However, embodiments of the present disclosure should not be limited to the specific disclosed forms, and should be construed to include all modifications, equivalents, or replacements included in the spirit and scope of the present disclosure.

In the present disclosure, it will be understood that when an element or layer is referred to as being “on”, “connected to” or “coupled to” another element or layer, it can be directly on, connected or coupled to the other element or layer or intervening elements or layers may be present.

Like numerals may refer to like elements throughout.

Hereinafter, embodiments of the present disclosure will be described with reference to accompanying drawings.

FIG. 1 is a perspective view of an electronic device DD according to an embodiment of the present disclosure. FIGS. 2A to 2C are cross-sectional views of electronic devices DD according to embodiments of the present disclosure.

According to embodiments, the electronic device DD is activated in response to electrical signals. The electronic device DD can be incorporated into various embodiments. For example, the electronic device DD can be incorporated into a large-sized electronic item, such as a television set, an outdoor billboard, etc., or a small or medium-sized electronic item, such as a mobile phone, a tablet computer, a car navigation unit, a game unit, etc. However, these are merely examples, and the electronic device DD can be incorporated into any other electronic device as long as it does not depart from concepts of the present disclosure. In a present embodiment, a mobile phone is shown as an example of the electronic device DD.

Referring to FIG. 1, according to an embodiment, the electronic device DD displays an image IM through a display surface DD-IS. The display surface DD-IS is substantially parallel to a plane defined by a first direction DR1 and a second direction DR2 that crosses the first direction DR1. In an embodiment, the second direction DR2 is perpendicular to the first direction DR1. A normal line direction of the display surface DD-IS is substantially parallel to a third direction DR3, and the third direction DR3 corresponds to a thickness direction of the electronic device DD.

In a present embodiment, front (or upper) and rear (or lower) surfaces of each member or each unit can be distinguished from each other with respect to a direction in which the image IM is displayed. However, directions indicated by the first, second, and third directions DR1, DR2, and DR3 are relative to each other and may be changed in other directions.

The electronic device DD includes a flat display surface DD-IS, however, embodiments are not limited thereto. In other embodiments, the electronic device DD includes a curved display surface or a three-dimensional display surface. A three-dimensional display surface includes a plurality of display areas that display images toward different directions from each other. For example, a three-dimensional display surface has a polygonal column-shaped display surface.

The electronic device DD is a rigid electronic device, however, embodiments are not limited thereto. In other embodiments, the electronic device DD is a flexible electronic device DD. A flexible electronic device DD may be a foldable electronic device or a bendable electronic device of which a portion thereof is bent.

The display surface DD-IS includes a transmissive area DD-DA through which the image IM is displayed and a bezel area DD-NDA through which no image IM is displayed. FIG. 1 shows application icons and a clock widget as representative examples of the image IM.

As shown in FIG. 1, in an embodiment, the transmissive area DD-DA has a substantially rectangular shape. The expression “substantially rectangular shape” refers not only to a rectangular shape as mathematically defined, but also a rectangular shape with rounded corners in which a vertex or corner area is rounded with a curved line boundary instead of a right-angled corner.

The bezel area DD-NDA is adjacent to the transmissive area DD-DA. For example, the bezel area DD-NDA surrounds the transmissive area DD-DA, however, embodiments are not limited thereto. The shape of the transmissive area DD-DA and the shape of the bezel area DD-NDA may be designed in various other ways in other embodiments. For example, in some embodiments, the bezel area DD-NDA is formed only at one side of the transmissive area DD-DA or is omitted. According to an embodiment, the bezel area DD-NDA is not exposed to the outside, depending on a combination of the display surface DD-IS and other components of the electronic device DD.

FIGS. 2A to 2C show electronic devices DD when viewed in a cross-section defined by the second direction DR2 and the third direction DR3. Referring to FIGS. 2A to 2C, in an embodiment, the electronic device DD may include a display panel DP, an input sensor ISP, an anti-reflective member RPP, and a window WP.

At least some components of the display panel DP, the input sensor ISP, the anti-reflective member RPP, and the window WP are formed through successive processes or can be attached to each other by an adhesive member ADS. FIGS. 2A to 2C schematically show various embodiments of a stack structure of components of the electronic device DD, however, these are merely examples of embodiments, and the stack structure of the components of the electronic device DD should not be limited thereto.

In embodiments of the present disclosure, when a component is formed by successive processes without using an adhesive layer or adhesive member, it can be expressed as “being directly disposed”. For example, the expression “component B is disposed directly on component A” means that the component “B” is formed on a base surface provided by the component “A” through successive processes after the component “A” is formed.

The adhesive member ADS is disposed between the components of the electronic device DD to attach the components to each other. The adhesive member ADS may be a transparent adhesive, such as a pressure sensitive adhesive (PSA) film, an optically clear adhesive (OCA) film, or an optically clear resin (OCR).

Some components of the electronic device DD are formed through successive processes and other components of the electronic device DD are attached to each other by the adhesive member ADS. Referring to FIG. 2A, in an embodiment, the input sensor ISP is disposed directly on the display panel DP to form a display module DM. The anti-reflective member RPP is disposed on the display module DM with the adhesive member ADS interposed therebetween. The window WP is disposed on the anti-reflective member RPP with the adhesive member ADS interposed therebetween.

Referring to FIG. 2B, according to an embodiment, components of the electronic device DD are coupled to each other by adhesive members ADS. That is, each of the display panel DP, the input sensor ISP, the anti-reflective member RPP, and the window WP is coupled to each other by the adhesive member ADS disposed therebetween.

Referring to FIG. 2C, according to an embodiment, components of the electronic device DD are formed through successive processes. The display panel DP, the input sensor ISP, the anti-reflective member RPP, and the window WP are sequentially stacked in the third direction DR3 through successive processes. That is, the input sensor ISP is disposed directly on the display panel DP, the anti-reflective member RPP is disposed directly on the input sensor ISP, and the window WP is disposed directly on the anti-reflective member RPP.

The display panel DP according to an embodiment is a light emitting type display panel, however, embodiments are not limited thereto. For example, the display panel DP may be an organic light emitting display panel or a quantum dot light emitting display panel. A light emitting layer of an organic light emitting display panel includes an organic light emitting material. A light emitting layer of a quantum dot light emitting display panel includes a quantum dot and/or a quantum rod. Hereinafter, an organic light emitting display panel will be described as a representative example of the display panel DP.

The input sensor ISP is disposed on the display panel DP and senses an external input applied thereto. The input sensor ISP obtains coordinate information of the external input. The external input may be a user input. The user input may include a variety of types of external inputs, such as contact with a part of user's body, light, heat, pen, or pressure.

The anti-reflective member RPP is disposed on the input sensor ISP. FIGS. 2A to 2C show embodiments in which the input sensor ISP is disposed closer to the display panel DP in the third direction DR3 than the anti-reflective member RPP, however, embodiments are not limited thereto. According to an embodiment, the stack order of the input sensor ISP and the anti-reflective member RPP may be changed. For example, the anti-reflective member RPP may be disposed on the display panel DP, and the input sensor ISP may be disposed on the anti-reflective member RPP.

The anti-reflective member RPP reduces reflectance of external light incident thereto from above the window WP. The anti-reflective member RPP includes at least one of a retarder or a polarizer. The retarder may be a film type or a liquid crystal coating type and may include a λ/2 retarder and/or a λ/4 retarder. The polarizer may be a film type or a liquid crystal coating type. The film type polarizer includes a stretching type synthetic resin film, and the liquid crystal coating type polarizer includes liquid crystals arranged in a predetermined arrangement.

According to an embodiment, the anti-reflective member RPP includes color filters. The color filters are arranged by taking into account the arrangement and the colors emitted by the pixels in the display panel DP. The anti-reflective member RPP may further include a black matrix disposed adjacent to and in between the color filters.

According to an embodiment, the anti-reflective member RPP includes a destructive interference structure. For example, the destructive interference structure includes a first reflection layer and a second reflection layer that are disposed on different layers from each other. A first reflection light and a second reflection light that are reflected by the first reflection layer and the second reflection layer, respectively, destructively interfere with each other, and thus, the reflectance of the external light is reduced.

The window WP forms an exterior of the electronic device DD. The window WP transmits images received from the display panel DP, and a user can view the images through the window WP. The window WP protects inner components of the electronic device DD from external impacts. For example, the window WP protects the display panel DP, the input sensor ISP, and the anti-reflective member RPP that are disposed thereunder.

Referring to FIG. 2A, in an embodiment, the window WP includes a base layer WP-BS and a light blocking pattern WP-BZ. On the other hand, in FIGS. 2B and 2C, the window WP is schematically shown without distinguishing the base layer WP-BS from the light blocking pattern WP-BZ.

The base layer WP-BS includes an optically transparent material. The base layer WP-BS includes at least one of a glass substrate or a synthetic resin film. The base layer WP-BS may have a single-layer or a multi-layer structure. For example, a multi-layer base layer WP-BS includes two or more synthetic resin films coupled to each other by adhesive members.

The light blocking pattern WP-BZ is disposed on a surface of the base layer WP-BS. The light blocking pattern WP-BZ overlaps a portion of the base layer WP-BS. An area in which the light blocking pattern WP-BZ is disposed corresponds to the bezel area DD-NDA of the electronic device DD. An area in which the light blocking pattern WP-BZ is not disposed corresponds to the transmissive area DD-DA of the electronic device DD.

The light blocking pattern WP-BZ may have a single-layer or multi-layer structure. A multi-layer light blocking pattern WP-BZ includes a chromatic color layer and an achromatic color light blocking layer, in particular, a black light blocking layer. The chromatic color layer and the achromatic color light blocking layer are formed on the base layer WP-BS through a depositing, printing, or coating process.

In addition, the window WP further includes a functional coating layer disposed on a front surface of the base layer WP-BS. The functional coating layer includes at least one of an anti-fingerprint layer, an anti-reflective layer, or a hard coating layer.

Referring to FIG. 8, the sensing unit SU2 includes portions of the first sensor portions SP1 that include the first connection portion CP1 interposed therebetween, and portions of the second sensor portions SP2 that are integrally connected to each other and include the second connection portion CP2 interposed therebetween. However, according to an embodiment, the sensing unit SU2 further includes dummy patterns DUP as shown in FIG. 8.

In an embodiment, a first cross direction DRa or a fourth direction and a second cross direction DRb or a fifth direction are additionally shown in FIG. 8 and the following drawings. The first cross direction DRa is a direction that crosses each of the first direction DR1 and the second direction DR2. The second cross direction DRb is a direction that crosses each of the first direction DR1 and the second direction DR2 and is substantially perpendicular to the first cross direction DRa. Each of the first cross direction DRa and the second cross direction DRb corresponds to a diagonal direction between the first direction DR1 and the second direction DR2 on a plane surface defined by the first direction DR1 and the second direction DR2.

Referring to FIG. 8, in an embodiment, each of the second sensor portions SP2 includes extension portions SP2a and SP2b and branch portions SP2c1, SP2c2, SP2c3 and SP2c4. The extension portions SP2a and SP2b includes a first extension portion SP2a that extends in the first direction DR1 and second extension portions SP2b that is bent and extends from the first extension portion SP2a in the first cross direction DRa and the second cross direction DRb such that a dummy pattern DUP is disposed therebetween, however, embodiments are not limited thereto. According to an embodiment, the dummy pattern DUP is not disposed between the second extension portions SP2b, and the second extension portion SP2b extend in a direction substantially diagonal to the first extension portion SP2a.

The branch portions SP2c1 to SP2c4 extend in the first cross direction DRa and the second cross direction DRb away from the second connection portion CP2 that is interposed therebetween. The branch portions SP2c1 to SP2c4 include first, second, third, and fourth branch portions SP2c1, SP2c2, SP2c3, and SP2c4. The first branch portion SP2c1 and the fourth branch portion SP2c4 extend in the first cross direction DRa, and the second branch portion SP2c2 and the third branch portion SP2c3 extend in the second cross direction DRb.

The first to fourth branch portions SP2c1 to SP2c4 extend away from each other in opposite directions. For example, the first branch portion SP2c1 extends away in the second direction DR2 from the second branch portion SP2c2 and extends away in the first direction DR1 from the third branch portion SP2c3. The first branch portion SP2c1 and the fourth branch portion SP2c4 extend away from each other in the first cross direction DRa with the second connection portion CP2 interposed therebetween, and the second branch portion SP2c2 and the third branch portion SP2c3 extend away from each other in the second cross direction DRb with the second connection portion CP2 interposed therebetween.

The second connection portion CP2 is disposed between portions of the first sensor portions SP1 that protrude toward each other in the second direction DR2. The second connection portion CP2 connects the first extension portions SP2a of the second sensor portions SP2. The second connection portion CP2 are disposed on the same layer as the first extension portions SP2a and are integrally formed with the first extension portions SP2a.

Each of the first sensor portions SP1 includes a first portion SP1b that extends in the second direction DR2 and a second portion SP1a that extends from the first portion SP1b and surrounds a portion of the second sensor portions SP2. The second portion SP1a of the first sensor portions SP1 surrounds the adjacent branch portions SP2c1 to SP2c4 of the second sensor portion SP2. Referring to FIG. 8, the second portion SP1a of the first sensor portion SP1 disposed at a left side of the sensing unit SU2 surrounds the first and third branch portions SP2c1 and SP2c3, and the second portion SP1a of the first sensor portion SP1 disposed at a right side of the sensing unit SU2 surrounds the second and fourth branch portions SP2c2 and SP2c4.

The first portions SP1b of the first sensor portions SP1 are spaced apart from each other in the second direction DR2 with the second connection portion CP2 interposed therebetween. The first connection portion CP1 electrically connects the spaced apart first sensor portions SP1. FIG. 8 shows two first connection portions CP1 disposed in the sensing unit SU2. However, embodiments are not limited thereto, and in other embodiments, the number of the first connection portions CP1 disposed in the sensing unit SU2 may be less than or greater than two.

As shown in FIG. 8, in an embodiment, the first connection portions CP1 have a turned V shape or a V shape when viewed in a plan view. The turned V shaped or V shaped first connection portions CP1 overlap the second sensor portions SP2, however, embodiments are not limited thereto. According to an embodiment, the first connection portions CP1 has a straight line shape that extends in the second direction DR2 and overlaps the second connection portion CP2 when viewed in a plan view.

The dummy patterns DUP are electrically floated. The dummy patterns DUP are insulated from the first and second electrode groups EG1 and EG2. The dummy patterns DUP include first, second, third, and fourth dummy patterns DUP1, DUP2, DUP3, and DUP4, according to their positions.

The first dummy patterns DUP1 are disposed between the first sensing electrodes IE1-1 to IE1-6 and the second sensing electrodes IE2-1 to IE2-4. In detail, the first dummy patterns DUP1 are disposed between the first sensor portions SP1 and the second sensor portions SP2. For example, the first dummy patterns DUP1 are disposed between the second portions SP1a of the first sensor portions SP1 and the branch portions SP2c1 to SP2c4 of the second sensor portions SP2 and surround the branch portions SP2c1 to SP2c4, as shown in FIG. 8.

Since the first dummy patterns DUP1 are disposed between the first sensor portions SP1 and the second sensor portions SP2, a mutual capacitance between the first sensor portions SP1 and the second sensor portions SP2 is reduced. However, although the first dummy patterns DUP1 are disposed between the first sensor portions SP1 and the second sensor portions SP2, an amount of the variation in mutual capacitance caused by occurrence of a touch event might not be significantly reduced. Accordingly, a value obtained by dividing the variation amount of the mutual capacitance by the mutual capacitance may increase due to the first dummy patterns DUP1.

Accordingly, a ghost touch phenomenon that occurs in a specific environment is reduced due to the first dummy patterns DUP1. A ghost touch phenomenon is a phenomenon in which a noise signal rather than a signal generated by an actual touch event is amplified and recognized as a touch. For example, when a temperature of a portion of the sensing area rises due to an operation such as a touch event in a low temperature state and the entire portion of the sensing area is turned on, an area within the sensing area in which no touch event is generated operates as if the touch occurs. However, the ghost touch phenomenon is reduced by the first dummy patterns DUP1, and a reliability of the input sensor ISP is increased.

A distance between the first sensor portions SP1 and the second sensor portions SP2 is increased by the first dummy patterns DUP1, and a possibility that the first sensor portions SP1 and the second sensor portions SP2 are shorted is reduced. For example, if no first dummy patterns DUP1 are disposed, the distance between the first sensor portions SP1 and the second sensor portions SP2 is on a scale from about 4 μm to about 5 μm, and when the first dummy patterns DUP1 are disposed, the distance between the first sensor portions SP1 and the second sensor portions SP2 increases on a scale of about 70 μm or more. Accordingly, the first sensor portions SP1 and the second sensor portions SP2 can be short-circuited only when a foreign substance or residue of size about 70 μm or more occurs in the area of the first dummy patterns DUP1.

The first dummy patterns DUP1 include a plurality of patterns electrically insulated from each other. A size of each of the patterns may change for each sensing unit SU2 by taking into account the mutual capacitance and the visibility. However, the first dummy patterns DUP1 are not limited thereto.

The second dummy patterns DUP2 are surrounded by the second extension portion SP2b of the second sensor portion SP2. The third dummy patterns DUP3 are surrounded by the first sensor portion SP1. The fourth dummy patterns DUP4 are disposed between the first sensing electrodes IE1-1 to IE1-6 arranged in the first direction DR1. However, according to embodiments, at least a portion of the first to fourth dummy patterns DUP1 to DUP4 may be omitted.

The cross-section shown in FIG. 9 corresponds to an area that overlaps one first connection portion CP1. In a present embodiment, the first connection portion CP1 is the bridge pattern.

However, according to an embodiment, the first sensor portion SP1, the second sensor portion SP2, and the second connection portion CP2 can be formed from the first conductive layer IS-CL1, and the first connection portion CP1 can be formed from the second conductive layer IS-CL2. According to an embodiment, the second connection portion CP2 is the bridge pattern and is disposed on a different layer different from that on which the first sensor portion SP1 and the second sensor portion SP2 are disposed, and the first connection portion CP1 is disposed on the same layer as the first sensor portion SP1 and the second sensor portion SP2.

In addition, the signal lines of the first signal line group SG1 and the second signal line group SG2 are formed from the second conductive layer IS-CL2, however, embodiments are not limited thereto. In an embodiment, the signal lines of the first signal line group SG1 and the second signal line group SG2 further include a portion formed from the first conductive layer IS-CL1, and have a two-layer structure. In this case, a portion of the signal lines formed from the second conductive layer IS-CL2 and a portion of the signal lines formed from the first conductive layer IS-CL1 are connected to each other via a contact hole formed through the second insulating layer IS-IL2. The two-layer signal lines have a low resistance.

Hereinafter, descriptions will be focused on those mesh patterns that correspond to inner areas of the first sensing electrodes IE1-1 to IE1-6 with reference to drawings, and the descriptions are applicable to the second sensing electrodes IE2-1 to IE2-4.

Referring to FIG. 10A, in an embodiment, the mesh opening rows M1 and M2 include a first row M1 and a second row M2. In the first row M1, the first mesh opening OP-M1 and the second mesh opening OP-M2 alternate with each other along the first cross direction DRa. In the second row M2, the second mesh opening OP-M2 and the third mesh opening OP-M3 alternate with each other along the first cross direction DRa. The first row M1 and the second row M2 alternate with each other in the second cross direction DRb. The second mesh opening OP-M2 in the first row M1 has a shape obtained by rotating the second mesh opening OP-M2 in the second row M2 by about 90 degrees.

Before the cut-away portion CT, shown in FIG. 10C, is formed, each of the conductive patterns COP includes the cross opening OP-C formed therethrough and spaced apart from the mesh opening OP-M. The cross openings OP-C are arranged in the first direction DR1 and the second direction DR2. The cross openings OP-C are alternately arranged with the mesh openings OP-M in the first direction DR1 and the second direction DR2.

Each of the cross openings OP-C includes a first side extending in the first direction DR1 and a second side extending in the second direction DR2. The cross openings OP-C have the same shape and the same size when viewed in a plan view, however, embodiments are not limited thereto.

The first side and the second side of each of the cross openings OP-C have different lengths from each other. Referring to FIG. 10A, a first side of each of first cross openings OP-C1 is longer than a second side thereof. A first side of each of second cross openings OP-C2 is shorter than a second side thereof. However, embodiments are not limited thereto, and in an embodiment, the first side and the second side of the cross openings OP-C have the same length as each other.

The cross openings OP-C include two or more openings whose first sides have different lengths. Referring to FIG. 10A, the cross openings OP-C include the first cross opening OP-C1 and the second cross opening OP-C2, and the length of the first side of the first cross opening OP-C1 differs from the length of the first side of the second cross opening OP-C2. The length of the first side of the first cross opening OP-C1 is greater than the length of the first side of the second cross opening OP-C2. For example, each of the first cross openings OP-C1 and the second cross openings OP-C2 has a rectangular shape, where the first cross openings OP-C1 extend lengthwise in the first direction DR1, and the second cross opening OP-C2 extend lengthwise in the second direction DR2. However, embodiments are not limited thereto and according to an embodiment, the cross openings OP-C have the same length with respect to the first side.

Although FIG. 10A shows each of the conductive patterns COP as including one cross opening OP-C formed therethrough before the cut-away portion CT, shown in FIG. 10C, is formed, however, in an embodiment, each of the conductive patterns COP includes a plurality of cross openings OP-C defined therethrough.

The conductive patterns COP are arranged in the first direction DR1 and the second direction DR2. The conductive patterns COP arranged in the second direction DR2 are defined as a conductive pattern row. A plurality of conductive pattern rows are provided, and the conductive pattern rows are arranged in the first direction DR1.

The conductive patterns COP that form a first conductive pattern row and the conductive patterns COP that form a second conductive pattern row are connected to each other by the mesh lines ML that extend in the first cross direction DRa or the second cross direction DRb. Accordingly, the conductive patterns COP that form the first conductive pattern row and the conductive patterns COP that form the second conductive pattern row are displaced from each other with respect to the first cross direction DRa and the second cross direction DRb.

The mesh lines ML include first mesh lines ML1 that extend in the first cross direction DRa and second mesh lines ML2 that extend in the second cross direction DRb. Each of the mesh lines ML connect the conductive patterns COP disposed at each end of the mesh line.

Before the cut-away portion CT, shown in FIG. 10C, is formed, the conductive patterns COP include a plurality of lines that form a closed line when viewed in a plan view. Each of the lines in the conductive patterns COP extends in a direction that crosses a direction in which the mesh lines ML extend. Referring to FIGS. 10A-C, the conductive patterns COP include lines each of which extends in the first direction DR1 or the second direction DR2 and which are connected to each other. FIG. 10A shows the conductive patterns COP as having a rectangular ring shape as a representative example. The cut-away portion CT, shown in FIG. 10C and described below, are formed in the conductive pattern COP by cutting at least one of the lines in the conductive patterns COP.

The conductive patterns COP and the mesh lines ML surround one of the mesh openings OP-M. In a present embodiment, the one opening surrounded by the conductive patterns COP and the mesh lines ML is defined as a center opening. For convenience of description, one of the second mesh openings OP-M2 will be described as a representative example of the center opening in FIG. 10A, and reference numerals of components are indicated based on the center opening.

The conductive patterns COP include first, second, third, and fourth conductive patterns COP1, COP2, COP3, and COP4 with the center opening interposed therebetween. The first conductive pattern COP1 and the second conductive pattern COP2 are separated in the first direction DR1 with the center opening interposed therebetween. The third conductive pattern COP3 and the fourth conductive pattern COP4 are separated in the second direction DR2 with the center opening interposed therebetween. The first mesh lines ML1 and the second mesh lines ML2 are disposed along an edge of the center opening.

The first conductive pattern COP1 and the third conductive pattern COP3 are connected to each other such that one second mesh line ML2 that extends in the second cross direction DRb is disposed therebetween. The second conductive pattern COP2 and the third conductive pattern COP3 are connected to each other such that one first mesh line ML1 that extends in the first cross direction DRa is disposed therebetween. The first conductive pattern COP1 and the fourth conductive pattern COP4 are connected to each other such that another first mesh line ML1 is disposed therebetween. The second conductive pattern COP2 and the fourth conductive pattern COP4 are connected to each other such that another second mesh line ML2 is disposed therebetween. Accordingly, the connected first to fourth conductive patterns COP1 to COP4 and the first and second mesh lines ML1 and ML2 form a center opening.

The conductive patterns COP and the mesh lines ML include the same conductive material. The conductive patterns COP and the mesh lines ML are integrally formed with each other. For example, the conductive patterns COP and the mesh lines ML are formed by patterning the same conductive layer.

Referring to FIG. 10B, in an embodiment, each of the conductive patterns COP includes the cutting portion P-CT. The cutting portion P-CT is a portion of the conductive patterns COP that is to be cut. In detail, the cutting portion P-CT is defined in at least one of the lines in the conductive patterns COP that is to be cut. After the cutting portion P-CT is cut, the cut portion of the conductive patterns COP forms the cut-away portion CT described below.

Referring to one conductive pattern COP, the cutting portion P-CT is defined such that at least one of the lines in the conductive pattern COP is integrally connected to the mesh lines ML and at least one line is cut to form end portions spaced apart from each other. Both ends of the line in the conductive pattern COP in which the cutting portion P-CT is not defined are connected to the first mesh line ML1 or the second mesh line ML2. One end of the line in the conductive pattern COP in which the cutting portion P-CT is defined is connected to the first mesh line ML1 or the second mesh line ML2 after being cut, and the other end of the line in the conductive pattern COP in which the cutting portion P-CT is defined is spaced apart from the mesh lines ML after being cut.

The cutting portion P-CT is defined in a longer line along the extension direction of the lines in the conductive patterns COP. Accordingly, a resistance of the conductive patterns COP is prevented from increasing, however, embodiments are not limited thereto.

The cutting portion P-CT is defined in the conductive pattern COP such that the cut-away portion CT formed by cutting the cutting portion P-CT opens toward one of the mesh openings. In the present disclosure, the expression “cut-away portion opens toward the mesh opening” means that “a separation space formed by cutting a portion of the conductive pattern defined by the cut-away portion is connected to an empty space where the mesh open forms an integral empty space”.

The cutting portion P-CT is defined such that some cut-away portions of the cut-away portions CT of the conductive patterns COP open toward the same opening, however, embodiments are not limited thereto. In an embodiment, the cutting portion P-CT is defined such that the cut-away portions CT of the conductive patterns COP opens toward different openings from each other. This will be described in detail with reference to drawings below.

FIG. 10C is a plan view of the conductive patterns COP in which the cut-away portion CT is formed by cutting the cutting portion P-CT of FIG. 10B. Referring to FIG. 10C, in an embodiment, each of the conductive patterns COP includes at least one cut-away portion CT formed therein. Since the cut-away portion CT is formed in each conductive pattern COP, the conductive patterns COP include lines spaced apart from each other with the cut-away portion CT interposed therebetween.

The cut-away portion CT opens toward one of the mesh openings. The cut-away portions CT of the conductive patterns COP, which include one center opening interposed therebetween, open toward the same center opening, however, embodiments are not limited thereto. According to an embodiment, some cut-away portions of the cut-away portions CT open toward the same center opening, and others of the cut-away portions of the cut-away portions CT open toward a different mesh opening from the center opening.

The cut-away portion CT connects the cross opening OP-C in the conductive pattern COP to the mesh opening OP-M adjacent to the conductive pattern COP. In a present embodiment, the expression “connect”, as used herein, means that the empty space in the cross opening OP-C and the empty space in the mesh opening OP-M are connected as an integral empty space with the empty space of the cut-away portion CT interposed therebetween.

FIGS. 11A to 11C are enlarged plan views of the first sensor portion SP1 of an area CC of FIG. 10C according to an embodiment of the present disclosure. FIG. 11A is centered on one second mesh opening OP-M2 of the first sensor portion SP1, shown in FIG. 10C. FIG. 11B is centered on one third mesh opening OP-M3 of the first sensor portion SP1, shown in FIG. 10C, and FIG. 11C is centered on one first mesh opening OP-M1 of the first sensor portion SP1, shown in FIG. 10C.

Referring to FIG. 11A, in an embodiment, the second mesh opening OP-M2 corresponds to the center opening. The first mesh openings OP-M1 are arranged along the first cross direction DRa with respect to the second mesh opening OP-M2. The third mesh openings OP-M3 are arranged along the second cross direction DRb with respect to the second mesh opening OP-M2.

The first to fourth conductive patterns COP1 to COP4 and the first and second mesh lines ML1 and ML2 are disposed along an edge of the second mesh opening OP-M2. The cut-away portions CT1 to CT4 are formed in the first to fourth conductive patterns COP1 to COP4, respectively.

Each of the first to fourth conductive patterns COP1 to COP4 includes lines that extend in different directions from the extension direction of the mesh lines ML. In this regard, the descriptions of the first to fourth conductive patterns COP1 to COP4 will be based on the first conductive pattern COP1 and the fourth conductive pattern COP4.

The first conductive pattern COP1 includes a first line LL1, a second line LL2, and a third line LL3, that extend in the first direction DR1. One end of the first line LL1 of the first conductive pattern COP1 is connected to the first mesh line ML1 and is connected to another conductive pattern by the first mesh line ML1. The other end of the first line LL1 of the first conductive pattern COP1 is connected to the second mesh line ML2 and is connected to another conductive pattern, such as the third conductive pattern COP3, by the second mesh line ML2. The one end of the first line LL1 of the first conductive pattern COP1 is also connected to one end of the second line LL2 of the first conductive pattern COP1, and the other end of the first line LL1 of the first conductive pattern COP1 is also connected to one end of the third line LL3 of the first conductive pattern COP1.

The one end of the second line LL2 of the first conductive pattern COP1 is connected to the second mesh line ML2, and thus is connected to another conductive pattern. However, the other end of the second line LL2 is spaced apart from the mesh line ML by the cut-away portion CT1. The one end of the third line LL3 of the first conductive pattern COP1 is connected to the first mesh line ML1 and is connected to another conductive pattern, such as the fourth conductive pattern COP4, by the first mesh line ML1. However, the other end of the third line LL3 is spaced apart from the mesh line ML by the cut-away portion CT1.

The other end of the second line LL2 of the first conductive pattern COP1 and the other end of the third line LL3 of the first conductive pattern COP1 are spaced apart from each other in the first direction DR1 with the cut-away portion CT1 interposed therebetween. The reflectance of light increases at the other ends of the second line LL2 and the third line LL3, and thus, a boundary between the sensing electrodes is prevented from being viewed.

The extension direction of the lines of the fourth conductive pattern COP4 that are spaced apart from each other with the cut-away portion CT4 interposed therebetween, differs from the extension direction of the lines of the first conductive pattern COP1 that are spaced apart from each other with the cut-away portion CT1 interposed therebetween. The fourth conductive pattern COP4 includes a first line LL1, a second line LL2, and a third line LL3 that extend in the second direction DR2. One end of the first line LL1 of the fourth conductive pattern COP4 is connected to the second mesh line ML2 and is connected to another conductive pattern, such as the second conductive pattern COP2, by the second mesh line ML2. The other end of the first line LL1 of the second conductive pattern COP2 is connected to the first mesh line ML1 and is connected to another conductive pattern by the first mesh line ML1. The one end of the first line LL1 of the fourth conductive pattern COP4 is also connected to one end of the second line LL2 of the fourth conductive pattern COP4, and the other end of the first line LL1 of the fourth conductive pattern COP4 is also connected to one end of the third line LL3 of the fourth conductive pattern COP4.

One end of the second line LL2 of the fourth conductive pattern COP4 is connected to the first mesh line ML1 and is connected to another conductive pattern, such as the first conductive pattern COP1. However, the other end of the second line LL2 is spaced apart from the mesh line ML by the cut-away portion CT4. The one end of the third line LL3 of the fourth conductive pattern COP4 is connected to the second mesh line ML2 and is connected to another conductive pattern by the second mesh line ML2. However, the other end of the third line LL3 is spaced apart from the mesh line ML by the cut-away portion CT4.

The other end of the second line LL2 of the fourth conductive pattern COP4 and the other end of the third line LL3 of the fourth conductive pattern COP4 are spaced apart from each other in the second direction DR2 with the cut-away portion CT4 interposed therebetween. The reflectance of the light increases at the other ends of the second line LL2 and the third line LL3, and thus, a boundary between the sensing electrodes is prevented from being viewed.

The details of the conductive patterns COP have been described with reference to the first conductive pattern COP1 and the fourth conductive pattern COP4, however, the descriptions of the first and fourth conductive patterns COP1 and COP4 are applicable to the other conductive patterns COP. In addition, the number of the lines included in the conductive patterns COP is not particularly limited as long as at least one cut-away portion CT is formed.

Some of the cut-away portions CT1 to CT4 of the first to fourth conductive patterns COP1 to COP4 open toward the same mesh opening. For example, the cut-away portion CT1 of the first conductive pattern COP1 and the cut-away portion CT4 of the fourth conductive pattern COP4 open toward the same third mesh opening OP-M3 as shown in FIG. 11A.

Some of the cut-away portions CT1 to CT4 of the first to fourth conductive patterns COP1 to COP4 open toward different mesh openings from each other. For example, the cut-away portion CT1 of the first conductive pattern COP1 and the cut-away portion CT3 of the third conductive pattern COP3 open toward different third mesh openings OP-M3, as shown in FIG. 11A.

The cut-away portion CT1 of the first conductive pattern COP1 and the cut-away portion CT2 of the second conductive pattern COP2 open toward different mesh openings. For example, the cut-away portion CT1 of the first conductive pattern COP1 and the cut-away portion CT2 of the second conductive pattern COP2 open in opposite directions. Similarly, the cut-away portion CT3 of the third conductive pattern COP3 and the cut-away portion CT4 of the fourth conductive pattern COP4 open in opposite directions.

The shape of the cut-away portions CT1 to CT4 of the first to fourth conductive patterns COP1 to COP4 may vary depending on which mesh opening corresponds to the center opening and is not particularly limited.

Referring to FIG. 11B, in an embodiment, the third mesh opening OP-M3 corresponds to the center opening. The second mesh openings OP-M2 are arranged in the first cross direction DRa and the second cross direction DRb with respect to the third mesh opening OP-M3. The second mesh openings OP-M2 are symmetrically arranged around the third mesh opening OP-M3.

The first to fourth conductive patterns COP1 to COP4 and the first and second mesh lines ML1 and ML2 are arranged along the edge of the third mesh opening OP-M3. The cut-away portions CT1 to CT4 are formed in the first to fourth conductive patterns COP1 to COP4, respectively.

The cut-away portion CT1 of the first conductive pattern COP1 and the cut-away portion CT2 of the second conductive pattern COP2 open toward the same mesh opening. For example, the cut-away portion CT1 of the first conductive pattern COP1 and the cut-away portion CT2 of the second conductive pattern COP2 face each other. Similarly, the cut-away portion CT3 of the third conductive pattern COP3 and the cut-away portion CT4 of the fourth conductive pattern COP4 face each other.

The cut-away portions CT1 to CT4 of the first to fourth conductive patterns COP1 to COP4 open toward the same mesh opening. As shown in FIG. 11B, the cut-away portions CT1 to CT4 of the first to fourth conductive patterns COP1 to COP4 open toward the same third mesh opening OP-M3, which corresponds to the center opening.

Referring to FIG. 11C, the first mesh opening OP-M1 corresponds to the center opening. The second mesh openings OP-M2 are arranged along the first cross direction DRa and the second cross direction DRb with respect to the first mesh opening OP-M1. The second mesh openings OP-M2 are symmetrically arranged around the first mesh opening OP-M1.

The first to fourth conductive patterns COP1 to COP4 and the first and second mesh lines ML1 and ML2 are arranged along the edge of the first mesh opening OP-M1. The cut-away portions CT1 to CT4 are formed in the first to fourth conductive patterns COP1 to COP4, respectively.

The cut-away portion CT1 of the first conductive pattern COP1 and the cut-away portion CT2 of the second conductive pattern COP2 open toward different mesh openings. Similarly, the cut-away portion CT3 of the third conductive pattern COP3 and the cut-away portion CT4 of the fourth conductive pattern COP4 open toward different mesh openings.

The cut-away portions CT1 to CT4 of the first to fourth conductive patterns COP1 to COP4 open toward different mesh openings. The cut-away portion CT1 of the first conductive pattern COP1 and the cut-away portion CT2 of the second conductive pattern COP2 open in opposite directions, and the cut-away portion CT3 of the third conductive pattern COP3 and the cut-away portion CT4 of the fourth conductive pattern COP4 opened in opposite directions.

The cut-away portions CT1 to CT4 of the first to fourth conductive patterns COP1 to COP4 open toward directions opposite to each other with respect to the first mesh opening OP-M1. The cut-away portions CT1 to CT4 of the first to fourth conductive patterns COP1 to COP4 do not opened toward the first mesh opening OP-M1, which corresponds to the center opening.

Since the cut-away portion CT is formed in the conductive patterns COP, the boundary between the first sensing electrode and the second sensing electrode is prevented from being viewed. Light reflectance is high at the boundary between the first sensing electrode and the second sensing electrode, and thus, the boundary between the first sensing electrode and the second sensing electrode can be viewed from the outside. However, since the cut-away portion CT is formed in each of the conductive patterns COP, light reflectance of the areas in which the cut-away portions CT are formed increases, and thus, light reflectance differences between the boundary of the first sensing electrode and the second sensing electrode and an inner portion of the first sensing electrode, or an inner portion of the second sensing electrode, is reduced. Accordingly, the visibility of the input sensor is reduced.

Since the conductive patterns COP include cut-away portions CT formed therein and are integrally connected to each other, the resistance of the conductive patterns COP is prevented from increasing even though the conductive patterns are partially cut. Accordingly, the mesh pattern MP reduces the visibility of the input sensor without increasing the resistance of the input sensor.

However, the first sensor portion SP1 shown in FIGS. 11A to 11C are merely examples, and the shape of the first to fourth conductive patterns COP1 to COP4 and the shape of the cut-away portions CT1 to CT4 can vary according to embodiments. Hereinafter, various embodiments of the first sensor portion SP1 will be described in detail with reference to drawings.

FIGS. 12A to 12C are enlarged plan views of first sensor portions SP1 that correspond to an area AA of FIG. 8 according to embodiments of the present disclosure. The first sensor portions SP1 shown in FIGS. 12A to 12C include substantially the same configurations as those of the first sensor portions SP1 shown in FIGS. 10A to 10C and 11A to 11C except for a position of the cut-away portions CT. In FIGS. 12A to 12C, the same reference numerals denote the same elements in FIGS. 10A to 10C and 11A to 11C, and thus, detailed descriptions of the same elements will be omitted.

For the convenience of description, in FIGS. 12A to 12C, one of the second mesh openings OP-M2 will be described as a representative example of a center opening, and reference numerals of components are indicated based on the center opening.

Referring to FIG. 12A, in an embodiment, a cut-away portion CT1 of a first conductive pattern COP1 and a cut-away portion CT2 of a second conductive pattern COP2, which are arranged along the first direction DR1, open toward the same direction. For example, the cut-away portions CT1 of each of the first conductive patterns COP1 and the cut-away portions CT2 of each of the second conductive patterns COP2 face right and open toward a mesh opening disposed at a right side thereof.

A cut-away portion CT3 of a third conductive pattern COP3 and a cut-away portion CT4 of a fourth conductive pattern COP4, which are arranged along the second direction DR2, open toward the same direction. For example, the cut-away portions CT3 of each of the third conductive patterns COP3 and the cut-away portions CT4 of each of the fourth conductive patterns COP4 face upward and open toward a mesh opening disposed at an upper side thereof.

The cut-away portion CT1 of the first conductive pattern COP1 opens toward the direction that crosses a facing direction of each of the cut-away portions CT3 of the third conductive patterns COP3 and the cut-away portions CT4 of the fourth conductive patterns COP4. For example, the cut-away portion CT1 of the first conductive pattern COP1 open toward the second direction DR2, and the cut-away portion CT3 of the third conductive pattern COP3 open toward the first direction DR1.

The cut-away portion CT1 of the first conductive pattern COP1 and the cut-away portion CT3 of the third conductive pattern COP3 open toward different mesh openings, and the cut-away portions CT1 of the first conductive pattern COP1 and the cut-away portions CT4 of the fourth conductive patterns COP4 open toward the same mesh opening.

The cut-away portions CT5 and CT6 of the conductive patterns, which are arranged along the second direction DR2 with respect to the first conductive pattern COP1, open toward the same direction as the cut-away portion CT1 of the first conductive pattern COP1. For example, the cut-away portion CT5 of the conductive pattern disposed at a left side of the first conductive pattern COP1 and the cut-away portion CT6 of the conductive pattern disposed at a right side of the first conductive pattern COP1 each open toward the second direction DR2 and toward a mesh opening disposed at a right side thereof.

Cut-away portions CT7 and CT8 of conductive patterns, which are arranged along the first direction DR1 with respect to the third conductive pattern COP3, open toward the same direction as the cut-away portion CT3 of the first conductive pattern COP3. For example, the cut-away portion CT7 of the conductive pattern disposed at a lower side of the third conductive pattern COP3 and the cut-away portion CT8 of the conductive pattern disposed at an upper side of the third conductive pattern COP3 each open toward the first direction DR1 and toward a mesh opening disposed at the upper side thereof.

Referring to FIG. 12B, in an embodiment, a cut-away portion CT1 of a first conductive pattern COP1 and a cut-away portion CT2 of a second conductive pattern COP2, which are arranged along the first direction DR1, open respectively toward opposite directions. For example, the cut-away portion CT1 of the first conductive pattern COP1 opens leftward toward a mesh opening disposed at a left side of the first conductive pattern COP1, and the cut-away portion CT2 of the second conductive pattern COP2 opens rightward toward a mesh opening disposed at a right side of the second conductive pattern COP2.

A cut-away portion CT3 of a third conductive pattern COP3 and a cut-away portion CT4 of a fourth conductive pattern COP4, which are arranged along the second direction DR2, open respectively toward opposite directions. For example, the cut-away portion CT3 of the third conductive pattern COP3 opens downward toward a mesh opening disposed at a lower side of the third conductive pattern COP3, and the cut-away portion CT4 of the fourth conductive pattern COP4 opens upward toward a mesh opening disposed at an upper side of the fourth conductive pattern COP4. However, the directions toward which the cut-away portions CT1, CT2, CT3, and CT4 open and the shapes of the cut-away portions CT1, CT2, CT3, and CT4 can change depending on which mesh opening is used as the center opening.

The cut-away portion CT1 of the first conductive pattern COP1 opens toward a different mesh opening from the mesh openings toward which each of the cut-away portions CT2, CT3, and CT4 of the second, third, and fourth conductive patterns COP2, COP3, and COP4 opens. The cut-away portions CT1, CT2, CT3 and CT4 of the first, second, third and fourth conductive patterns COP1, COP2, COP3 and COP4, respectively, each face a different mesh opening.

Among the cut-away portions CT5 and CT6 of the conductive patterns arranged in the second direction DR2 with the first conductive pattern COP1, one cut-away portion opens in a same direction as the cut-away portion CT1 of the first conductive pattern COP1, and the other cut-away portion opens in a direction opposite to that of the cut-away portion CT1 of the first conductive pattern COP1. For example, the cut-away portion CT5 of the conductive pattern disposed at a left side of the first conductive pattern COP1 faces the cut-away portion CT1 of the first conductive pattern COP1 and opens in an opposite direction toward the same mesh opening as the cut-away portion CT1 of the first conductive pattern COP1. The cut-away portion CT6 of the conductive pattern disposed at a right side of the first conductive pattern COP1 faces away from the cut-away portion CT1 of the first conductive pattern COP1 and opens in a same direction as the cut-away portion CT1 and toward the mesh opening disposed at the right side thereof.

Among cut-away portions CT7 and CT8 of conductive patterns arranged along the first direction DR1 with the third conductive pattern COP3, one cut-away portion opens toward a same direction as the cut-away portion CT3 of the third conductive pattern COP3, and the other cut-away portion opens in a direction opposite to that of the cut-away portion CT3 of the third conductive pattern COP3. For example, the cut-away portion CT7 of the conductive pattern disposed at a lower side of the third conductive pattern COP3 faces the cut-away portion CT3 of the third conductive pattern COP3 and opens in an opposite direction toward the same mesh opening as the cut-away portion CT3 of the third conductive pattern COP3. The cut-away portion CT8 of the conductive pattern disposed at an upper side of the third conductive pattern COP3 faces away from the cut-away portion CT3 of the third conductive pattern COP3 and in a same direction as the cut-away portion CT3 toward the mesh opening disposed at the upper side thereof.

Referring to FIG. 12C, in an embodiment, a cut-away portion CT1 of a first conductive pattern COP1 and a cut-away portion CT2 of a second conductive pattern COP2, which are arranged along the first direction DR1, open toward the same direction. For example, each of the cut-away portion CT1 of the first conductive pattern COP1 and the cut-away portion CT2 of the second conductive pattern COP2 opens leftward toward a mesh opening disposed at a left side thereof.

A cut-away portion CT3 of a third conductive pattern COP3 and a cut-away portion CT4 of a fourth conductive pattern COP4, which are arranged along the second direction DR2, open respectively toward opposite directions. For example, the cut-away portion CT3 of the third conductive pattern COP3 opens downward toward a mesh opening disposed at a lower side of the third conductive pattern COP3, and the cut-away portion CT4 of the fourth conductive pattern COP4 opens upward toward a mesh opening disposed at an upper side of the fourth conductive pattern COP4, or vice versa. However, the directions toward which the cut-away portions CT1, CT2, CT3, and CT4 open and the shapes of the cut-away portions CT1, CT2, CT3, and CT4 can changed depending on which mesh opening is used as the center opening.

Each of the cut-away portions CT5 and CT6 of the conductive patterns arranged along the second direction DR2 with the first conductive pattern COP1 opens toward the same direction as the cut-away portion CT1 of the first conductive pattern COP1. For example, each of the cut-away portions CT5 and CT6 of the conductive patterns respectively disposed at left and right sides of the first conductive pattern COP1 opens leftward toward a mesh opening disposed at a left side thereof.

Among cut-away portions CT7 and CT8 of conductive patterns arranged along the first direction DR1 with the third conductive pattern COP3, one cut-away portion opens toward a same direction as the cut-away portion CT3 of the third conductive pattern COP3, and the other cut-away portion opens toward a opposite direction to the cut-away portion CT3 of the third conductive pattern COP3.

However, the first sensor portions SP1 shown in FIGS. 12A to 12C are merely examples, and embodiments are not limited thereto. The mesh pattern MP of embodiments of the present disclosure are not particularly limited as long as the mesh pattern MP includes the integrally connected conductive patterns COP, the cut-away portions CT respectively formed therein, and the mesh lines ML that connect the conductive patterns COP.

FIGS. 13A to 13E are enlarged plan views of first sensor portions SP1 that correspond to an area AA of FIG. 8 according to embodiments of the present disclosure. The first sensor portions SP1 shown in FIGS. 13A to 13E include substantially the same configurations as those of embodiments described above except for a shape of conductive patterns COP. In FIGS. 13A to 13E, the same reference numerals denote the same elements described above, and thus, detailed descriptions of the same elements will be omitted.

For the convenience of description, in FIGS. 13A to 13E, one of the second mesh openings OP-M2 will be described as a representative example of a center opening, and reference numerals of components are indicated based on the center opening.

As shown in FIG. 10C, in an embodiment, one cut-away portion CT is formed in each of the conductive patterns COP, however, embodiments are not limited thereto. According to an embodiment, at least one of the conductive patterns COP includes two or more cut-away portions formed therein. This will be described in detail with reference to FIGS. 13A to 13E.

FIG. 13A shows conductive patterns COP in which no cut-away portion CT is formed. Referring to FIG. 13A, in an embodiment, each of the conductive patterns COP in which no cut-away portion CT is formed includes a plurality of lines that form a plurality of closed lines when viewed in a plan view. FIG. 13A shows the conductive patterns COP as including three lines that extend in the same direction as a representative example.

One cut-away portion is formed in the third conductive pattern COP3, and the cut-away portion of the third conductive pattern COP3 and the first cut-away portion CT1-1 of the first conductive pattern COP1 open toward different mesh openings. The cut-away portion CT4 of a fourth conductive pattern COP4 and the cut-away portion of the third conductive pattern COP3 open in opposite directions. However, embodiments are not limited thereto.

The conductive patterns COP are not limited to embodiments shown in FIG. 13C. According to an embodiment, each of the conductive patterns COP includes one cut-away portion formed therein. That is, each of the third and fourth conductive patterns COP3 and COP4 includes one cut-away portion as shown in FIG. 13C or FIG. 13D.

Referring to FIG. 13D, in an embodiment, some of cut-away portions CT of conductive patterns COP connect a plurality of cross openings OP-C, shown in FIG. 13A, in one conductive pattern COP. For example, a cut-away portion CT4 of a fourth conductive pattern COP4 separates a centermost fifth line LL2 and opens toward the cross openings OP-C, and the cross openings OP-C connected to each other by the cut-away portion CT4 form an integral cross opening.

The cut-away portion CT4 of the fourth conductive pattern COP4 is formed in one of the fifth lines LL-2.

Although the conductive patterns include one cut-away portion that opens toward one mesh opening, the conductive patterns may have a variety of shapes. For example, each of the fourth conductive pattern COP4 of FIG. 13E and the fourth conductive pattern COP4 of FIG. 13C includes one cut-away portion CT4 formed therein, however, the fourth conductive pattern COP4 of FIG. 13E and the fourth conductive pattern COP4 of FIG. 13C have different shapes. The number of lines in the fourth conductive pattern COP4 of FIG. 13E in which no cut-away portion CT4 is formed differs from the number of the lines in the fourth conductive pattern COP4 of FIG. 13C in which no cut-away portion CT4 is formed.

As described with reference to FIGS. 13A to 13E, the shape of the conductive patterns COP in the mesh pattern MP may have various forms as long as the cut-away portion CT can be formed without insulating the mesh pattern MP and embodiments are not limited to embodiments shown in the figures.

FIG. 14 is a plan view of a mesh pattern MP in which no cut-away portion CT is formed. FIGS. 15A to 15C are plan views that show the mesh pattern MP of FIG. 14 in which the cut-away portion CT is formed. The mesh pattern MP shown in FIG. 14 includes substantially the same configurations as those of an embodiment described with reference to FIG. 10A except for a shape of the mesh pattern MP. In FIG. 14, the same reference numerals denote the same elements in as described above, and thus, detailed descriptions of the same elements will be omitted.

Referring to FIG. 14, in an embodiment, mesh openings OP-M formed in the mesh pattern MP have substantially the same size. Before the cut-away portion CT, shown in FIG. 15A, is formed, cross openings OP-C that are respectively formed in conductive patterns COP have substantially the same size as each other.

Each of the cross openings OP-C includes a first side that extends in the first direction DR1 and a second side that extends in the second direction DR2. The first and second sides in each of the cross openings OP-C have substantially the same length. In addition, the lengths of the first sides of the cross openings OP-C are the same, and the lengths of the second sides of the cross openings OP-C are the same.

FIGS. 15A to 15C show various embodiments of the mesh pattern MP of FIG. 14 after the cut-away portion CT is formed in the mesh pattern MP. The embodiments shown in FIGS. 15A to 15C differ from those described above in positions at which the cut-away portions CT are formed. For convenience of description, in FIGS. 15A to 15C, one of the mesh openings OP-M will be described as a representative example of a center opening, and reference numerals of components are indicated based on the center opening.

Referring to FIG. 15A, in an embodiment, cut-away portions CT1, CT2, CT3, and CT4 of first, second, third, and fourth conductive patterns COP1, COP2, COP3, and COP4, respectively, open toward a direction substantially parallel to the second direction DR2, however, embodiments are should not limited thereto. In an embodiment, the cut-away portions CT1 to CT4 of the first to fourth conductive patterns COP1 to COP4 open toward a direction substantially parallel to the first direction DR1.

The cut-away portion CT1 of the first conductive pattern COP1 and the cut-away portion CT2 of the second conductive pattern COP2, which are arranged in the first direction DR1, open respectively toward opposite directions. For example, the cut-away portion CT1 of the first conductive pattern COP1 opens leftward toward a left mesh opening of the first conductive pattern COP1, and the cut-away portion CT2 of the second conductive pattern COP2 open rightward toward a right mesh opening of the second conductive pattern COP2.

The cut-away portion CT3 of the third conductive pattern COP3 and the cut-away portion CT4 of the fourth conductive pattern COP4, which are arranged in the second direction DR2, open respectively toward directions that either face each other or are opposite to each other. The cut-away portion CT3 of the third conductive pattern COP3 and the cut-away portion CT4 of the fourth conductive pattern COP4 open toward the same mesh opening, however, embodiments are not limited thereto. According to an embodiment, the cut-away portion CT3 of the third conductive pattern COP3 and the cut-away portion CT4 of the fourth conductive pattern COP4 open toward different mesh openings.

Referring to FIG. 15B, in an embodiment, a cut-away portion CT1 of a first conductive pattern COP1 and a cut-away portion CT4 of a fourth conductive pattern COP4 open toward the same direction, and the cut-away portion CT1 of the first conductive pattern COP1 opens toward a direction that crosses an opening direction of each of a cut-away portion CT2 of a second conductive pattern COP2 and a cut-away portion CT3 of a third conductive pattern COP3. For example, the cut-away portions CT1 and CT4 of the first and fourth conductive patterns COP1 and COP4 open toward the first direction DR1, and the cut-away portions CT2 and CT3 of the second and third conductive patterns COP2 and COP3 open toward the second direction DR2.

The cut-away portion CT1 of the first conductive pattern COP1 and the cut-away portion CT4 of the fourth conductive pattern COP4 open toward the same direction. For example, the cut-away portion CT1 of the first conductive pattern COP1 opens downward toward a mesh opening disposed at a lower side of the first conductive pattern COP1, and the cut-away portion CT4 of the fourth conductive pattern COP4 opens downward toward a mesh opening disposed at a lower side of the fourth conductive pattern COP4.

The cut-away portion CT2 of the second conductive pattern COP2 and the cut-away portion CT3 of the third conductive pattern COP3 open toward the same direction. For example, the cut-away portion CT2 of the second conductive pattern COP2 opens rightward toward a mesh opening disposed at a right side of the second conductive pattern COP2, and the cut-away portion CT3 of the third conductive pattern COP3 opens rightward toward a mesh opening disposed at a right side of the third conductive pattern COP3.

Referring to FIG. 15C, in an embodiment, a cut-away portion CT1 of a first conductive pattern COP1 and a cut-away portion CT2 of a second conductive pattern COP2 open toward opposite directions, and the cut-away portion CT1 of the first conductive pattern COP1 opens toward a direction that crosses an opening direction of each of a cut-away portion CT3 of a third conductive pattern COP3 and a cut-away portion CT4 of a fourth conductive pattern COP4.

For example, the cut-away portions CT1 and CT2 of the first and second conductive patterns COP1 and COP2 open respectively toward directions substantially parallel to the second direction DR2, and the cut-away portions CT3 and CT4 of the third and fourth conductive patterns COP3 and COP4 open respectively toward directions substantially parallel to the first direction DR1. In addition, the opening direction of cut-away portion CT1 is opposite to that of cut-away portion CT2, and the opening direction cut-away portion CT3 is opposite to that of cut-away portion CT4.

The cut-away portion CT1 of the first conductive pattern COP1 and the cut-away portion CT3 of the third conductive pattern COP3 open toward the same mesh opening, and the cut-away portion CT2 of the second conductive pattern COP2 and the cut-away portion CT4 of the fourth conductive pattern COP4 open toward the same mesh opening. Accordingly, some mesh openings are faced by four cur-away portions, and other mesh openings have no facing cut-away portions.

The cut-away portions CT1 to CT4 of the first to fourth conductive patterns COP1 to COP4, respectively, open toward the same mesh opening as each other, however, embodiments are not limited thereto. According to an embodiment, the cut-away portions CT1 to CT4 of the first to fourth conductive patterns COP1 to COP4 open toward different mesh openings.

The embodiments shown in FIGS. 15A to 15C are merely examples and are not particularly limited as long as the mesh pattern MP include the conductive patterns COP with cut-away portions CT that open toward the mesh opening OP-M and mesh lines ML that connect the conductive patterns COP.

FIG. 16 is an enlarged plan view of a first sensor portion SP1 that corresponds to an area AA of FIG. 8 according to an embodiment of the present disclosure. FIG. 17 is an enlarged plan view of the first sensor portion SP1 that corresponds to an area EE of FIG. 16 according to an embodiment of the present disclosure. FIG. 18 is a cross-sectional view taken along a line II-II′ of FIG. 16 to show a display module according to an embodiment of the present disclosure.

According to an embodiment, FIG. 16 shows a plurality of light emitting areas PXA that overlap mesh openings OP-M. The display panel DP includes light emitting areas PXA that respectively correspond to the light emitting elements OLE. As described above in FIG. 4B the light emitting areas PXA correspond to portions of first electrodes AE of the light emitting elements OLE that are exposed through the light emitting openings OP of the pixel definition layer PDL.

Referring to FIG. 16, in an embodiment, the light emitting areas PXA include a first light emitting area PXA-1, a second light emitting area PXA-2, and a third light emitting area PXA-3, which are distinguished from each other according to the color of light generated by the light emitting elements OLE. The first light emitting area PXA-1, the second light emitting area PXA-2, and the third light emitting area PXA-3 have different sizes from each other depending on the color of light emitted therefrom. As shown in FIG. 16, of the light emitting areas PXA, the first light emitting area PXA-1 has the largest size, and the second light emitting area PXA-2 has the smallest size when viewed in a plan view, however, embodiments are not limited thereto. In an embodiment, the sizes of the first light emitting area PXA-1, the second light emitting area PXA-2, and the third light emitting area PXA-3 are the same as each other.

The first light emitting area PXA-1 is an area from which a first color light is emitted, the second light emitting area PXA-2 is an area from which a second color light is emitted, and the third light emitting area PXA-3 is an area from which a third color light is emitted. For example, each of the first, second, and third color light is one of blue, green, or red light.

The mesh openings OP-M overlap the light emitting areas PXA. For example, one mesh opening OP-M overlaps one light emitting area PXA. When viewed in a plan view, a first mesh opening OP-M1 overlaps the first light emitting area PXA-1, a second mesh opening OP-M2 overlaps the second light emitting area PXA-2, and a third mesh opening OP-M3 overlaps the third light emitting area PXA-3.

When viewed in a plan view, the mesh openings OP-M are greater in size than the light emitting areas PXA that overlap therewith. For example, the size of the first mesh opening OP-M1 that overlaps the first light emitting area PXA-1 is greater than the size of the first light emitting area PXA-1.

When viewed in a plan view, each of the mesh openings OP-M has a shape that corresponds to the shape of the overlapping light emitting area PXA. For example, the mesh opening OP-M that overlaps a light emitting area PXA that has a lozenge shape in a plane will have a lozenge shape.

The light emitting areas PXA are arranged in the first cross direction DRa and the second cross direction DRb. The first light emitting area PXA-1 alternate with the second light emitting area PXA-2 in the first cross direction DRa and the second cross direction DRb, and the third light emitting area PXA-3 alternate with the second light emitting area PXA-2 in the first cross direction DRa and the second cross direction DRb. The first light emitting area PXA-1 and the third light emitting area PXA-3 alternately arranged with each other in the first direction DR1 and the second direction DR2.

FIG. 17 is an enlarged plan view of the first sensor portion SP1 based on one second mesh opening OP-M2 shown in FIG. 16. In FIG. 17, the second mesh opening OP-M2 will be described as a representative example of a center opening, and reference numerals of components are indicated based on the center opening for the convenience of description.

Referring to FIG. 17, in an embodiment, the first mesh openings OP-M1 are spaced apart from each other in the first cross direction DRa with the second mesh opening OP-M2 interposed therebetween. The third mesh openings OP-M3 are spaced apart from each other in the second cross direction DRb with the second mesh opening OP-M2 interposed therebetween.

The first conductive pattern COP1 and the second conductive pattern COP2 are arranged in the first direction DR1 with the second mesh opening OP-M2 interposed therebetween, and the third conductive pattern COP3 and the fourth conductive pattern COP4 are arranged in the second direction DR2 with the second mesh opening OP-M2 interposed therebetween.

Each of the first conductive pattern COP1 and the second conductive pattern COP2 is disposed between the first mesh opening OP-M1 and the third mesh opening OP-M3 in the second direction DR2. Each of the third conductive pattern COP3 and the fourth conductive pattern COP4 is disposed between the first mesh opening OP-M1 and the third mesh opening OP-M3 in the first direction DR1.

Each of the mesh lines ML extends in the first cross direction DRa or the second cross direction DRb and connects the conductive patterns COP. One of the mesh lines ML that extends in the first cross direction DRa connects the first conductive pattern COP1 to the fourth conductive pattern COP4, and the other of the mesh lines ML connects the second conductive pattern COP2 to the third conductive pattern COP3. Of the mesh lines ML that extend in the second cross direction DRb, one mesh line connects the first conductive pattern COP1 to the third conductive pattern COP3, and the other mesh line connects the second conductive pattern COP2 to the fourth conductive pattern COP4.

The cut-away portions CT1 to CT4 are formed in the first to fourth conductive patterns COP1 to COP4, respectively. Each of the cut-away portions CT1 to CT4 of the first to fourth conductive patterns COP1 to COP4 opens toward the third mesh opening OP-M3. For example, the cut-away portion CT1 of the first conductive pattern COP1 and the cut-away portion CT4 of the fourth conductive pattern COP4 open toward the same third mesh opening OP-M3. The cut-away portion CT1 of the first conductive pattern COP1 and the cut-away portion CT3 of the third conductive pattern COP3 open toward different third mesh openings OP-M3.

When the third mesh opening OP-M3 corresponds to the center opening, the cut-away portions CT of the conductive patterns COP arranged with the third mesh opening OP-M3 interposed therebetween open toward the same third mesh opening OP-M3 that corresponds to the center opening.

The light emitted from the first light emitting area PXA-1 has a wavelength shorter than a wavelength of the light emitted from the second light emitting area PXA-2. The light emitted from the third light emitting area PXA-3 has a wavelength longer than the wavelength of the light emitted from the second light emitting area PXA-2. For example, the first color light is blue, the second color light is green, and the third color light is red, however, embodiments are not limited thereto.

A reflectance of light at a point where the cut-away portion CT is formed changes depending on the wavelength of light emitted from the light emitting area PXA that overlaps the mesh opening OP-M. The light reflectance is controlled according to where the cut-away portion CT is formed, and thus, the visibility of the input sensor ISP is efficiently reduced.

A center of the mesh openings OP-M corresponds to a center of the overlapping light emitting area PXA. When viewed in a plan view, a separation interval between the light emitting area PXA and the mesh pattern MP is uniform. For example, a shortest separation distance between the light emitting area PXA and the mesh lines ML is substantially the same as a shortest separation distance between the light emitting area PXA and the conductive patterns COP.

Referring to FIG. 17, in an embodiment, a shortest separation interval D-C1 between the first light emitting area PXA-1 that overlaps the first mesh opening OP-M1 and the first conductive pattern COP1 is substantially the same as a shortest separation interval D-M1 between the first light emitting area PXA-1 and the mesh line ML. A shortest separation interval D-C2 between the second light emitting area PXA-2 that overlaps the second mesh opening OP-M2 and the first conductive pattern COP1 is substantially the same as a shortest separation interval D-M2 between the second light emitting area PXA-2 and the mesh line ML. A shortest separation interval D-C3 between the third light emitting area PXA-3 that overlaps the third mesh opening OP-M3 and the third conductive pattern COP3 is substantially the same as a shortest separation interval D-M3 between the third light emitting area PXA-3 and the mesh line ML.

When light emitted from the light emitting area PXA that overlaps the mesh opening OP-M is reflected by the mesh pattern MP, the reflected light influences color change characteristics according to a viewing angle, such as a white angle difference (WAD). According to an embodiment, as the shortest separation distance between the light emitting area PXA and the mesh lines ML is substantially the same as the shortest separation distance between the light emitting area PXA and the conductive patterns COP, a reflection difference of the light according to display area is reduced. Accordingly, a difference in color change characteristics according to the viewing angle is reduced, and a color difference of the emitted light caused by the viewing angle is reduced.

FIG. 18 is a cross-section of the display module DM corresponding to the first light emitting area PXA-1 and the third light emitting area PXA-3. Details of the same components described above are applicable to components shown in FIG. 18.

Referring to FIG. 18, in an embodiment, light emitting elements OLE1 and OLE2 overlap light emitting openings OP of the pixel definition layer PDL, respectively. As shown in FIG. 18, a first electrode AE of a first light emitting element OLE1 exposed through the light emitting opening OP of the pixel definition layer PDL corresponds to the first light emitting area PXA-1, and a first electrode AE of a second light emitting element OLE2 exposed through the light emitting opening OP of the pixel definition layer PDL corresponds to the third light emitting area PXA-3. The first light emitting element OLE1 and the second light emitting element OLE2 emit different color light, however, embodiments are not limited thereto. According to an embodiment, the first light emitting element OLE1 and the second light emitting element OLE2 emit the same color light.

The first sensor portion SP1 of FIG. 16 is formed in a second conductive layer IS-CL2, and the cross-section of FIG. 18 is shown based on this. However, according to an embodiment, the first sensor portion SP1 is formed in the first conductive layer IS-CL1, shown in FIG. 6.

Each of the conductive patterns COP overlaps a non-light-emitting area NPXA. The mesh opening OP-M is formed between the conductive pattern COP and another conductive pattern COP. As shown in FIG. 18, the first mesh opening OP-M1 disposed between the conductive patterns COP overlaps the first light emitting area PXA-1, and the third mesh opening OP-M3 overlaps the third light emitting area PXA-3.

The cross opening OP-C is formed in the conductive pattern COP. The cross opening OP-C of the conductive pattern COP overlaps the non-light-emitting area NPXA. The cut-away portion CT formed in the conductive pattern COP connects the cross opening OP-C to a mesh opening OP-M adjacent to the conductive pattern COP.

FIG. 19 is an enlarged plan view of sensor portions that correspond to an area BB of FIG. 8 according to an embodiment of the present disclosure. The area BB shown in FIG. 19 corresponds to a boundary area between the first sensor portion SP1 and the second sensor portion SP2. FIG. 19 shows an imaginary boundary line BDL, hereinafter referred to as a boundary line BDL, that determines a boundary between the first sensor portion SP1 and the second sensor portion SP2.

Each of the first sensor portion SP1 and the second sensor portion SP2 include the mesh pattern MP. Details of the mesh pattern MP are described with reference to the area AA of FIG. 8, which corresponds to an inner area of the first sensor portion SP1, and the descriptions thereof are applicable to the second sensor portion SP2.

The mesh pattern MP in the first sensor portion SP1 includes a plurality of protrusion portions PR1 adjacent to the boundary line BDL. The protrusion portions PR1 in the first sensor portion SP1 may be defined as first protrusion portions PR1.

The mesh pattern MP in the second sensor portion SP2 may include a plurality of protrusion portions PR2 adjacent to the boundary line BDL. The protrusion portions PR2 in the second sensor portion SP2 may be defined as second protrusion portions PR2.

The first protrusion portions PR1 are integrally formed with the conductive patterns COP and the mesh lines ML, which are disposed on the same layer. Similarly, the second protrusion portions PR2 are integrally formed with the conductive patterns COP and the mesh line ML, which are included in the mesh pattern MP of the second sensor portion SP2 on the same layer.

The first protrusion portions PR1 are spaced apart from the second protrusion portions PR2 such that the boundary line BDL is formed therebetween. Accordingly, the first sensor portion SP1 and the second sensor portion SP2 are electrically insulated from each other.

The first protrusion portions PR1 and the second protrusion portions PR2 protrude toward each other with the boundary line BDL formed therebetween.

The first protrusion portions PR1 includes a first protrusion PR1a that protrudes in the second direction DR2 and a second protrusion PR1b that protrudes in the first direction DR1. The second protrusion portions PR2 include a first protrusion PR2a that protrudes in the second direction DR2 and a second protrusion PR2b that protrudes in the first direction DR1.

The first protrusion PR1a of the first protrusion portions PR1 and the first protrusion PR2a of the second protrusion portions PR2 protrude toward each other in the second direction DR2. The second protrusion PR1b of the first protrusion portions PR1 and the second protrusion PR2b of the second protrusion portions PR2 protrude toward each other in the first direction DR1.

A direction in which the boundary line BDL extends changes depending on in which portion of the first sensor portion SP1 and the second sensor portion SP2 the boundary line BDL is defined. FIG. 19 shows the boundary line BDL as extending in the first cross direction DRa and having a zigzag shape as a representative example, however, embodiments are not limited thereto. According to an embodiment, the boundary line BDL may extend in the first cross direction DRa or the second cross direction DRb and has a straight line shape.

According to an embodiment, a mesh pattern includes conductive patterns and mesh lines that are disposed on the same layer and connected to each other to form openings. The conductive patterns are integrally connected with the mesh lines, respectively, and the cut-away portions that open toward a mesh opening are formed in the conductive patterns. Accordingly, a resistance of an input sensor that includes the mesh pattern does not increase, and the mesh pattern of the input sensor is prevented from being viewed. According to an embodiment, the mesh pattern are formed such that the distance between the light emitting area and the mesh pattern becomes uniform, and thus, differences in color change characteristics according to the viewing angle are reduced.

Although embodiments of the present disclosure have been described, it is understood that embodiments of the present disclosure should not be limited to these embodiments but various changes and modifications can be made by one ordinary skilled in the art within the spirit and scope as hereinafter claimed. Therefore, the disclosed subject matter should not be limited to any single embodiment described herein, and the scope of embodiments of the present inventive concept shall be determined according to the attached claims.
