The following embodiments of the present invention are provided to those skilled in the art in order to describe the present invention more completely. Accordingly, shapes and sizes of elements shown in the drawings may be exaggerated for clarity.
Hereinafter, a liquid crystal display panel is used as an example of a display panel. Other display panels may be used. For example, a plasma display panel (PDP), a field emission display (FED) panel, and an organic light emitting diode (OLED) display panel may be used.
As shown in
Although not shown, the display panel 100 may include a front substrate and a back substrate that are positioned opposite each other. The bracket 140 may be attached to a back surface of the back substrate of the display panel 100.
The optical layer 110 may be fixed to the bracket 140. The optical layer 110 may include a plurality of sheets. For example, although not shown, the optical layer 110 may include at least one of a prism sheet and a diffusion sheet.
The backlight unit 10B may be positioned in the rear of the optical layer 110. Although not shown, the backlight unit 10B may further include a frame as well as the light source 120. In the embodiment disclosed herein, the backlight unit 10B includes the light source 120, the optical layer 110, and the frame (not shown). However, the backlight unit 10B may include a light guide plate (not shown). Further, in the embodiment disclosed herein, the backlight unit may be used as the light source 120 and thus may indicate the light source 120. In other word, the backlight unit 10B may be referred to as the light source. The configuration of the backlight unit may be variously changed.
Various types of light sources 120 may be used in the embodiment of the invention. For example, the light source may be one of a light emitting diode (LED) chip and a LED package having at least one LED chip. In this instance, the light source may be a colored LED emitting one of red, green, and blue light or a white LED.
The back cover 130 may be positioned in the rear of the backlight unit 10B. The back cover 130 may protect the backlight unit 10B and the optical layer 110 from the outside.
The optical layer 110 may be closely attached to the display panel 100. Alternatively, the backlight unit 10B may be closely attached to the optical layer 110. In this instance, a thickness of the display device according to the embodiment of the invention may be reduced.
As shown in
A color filter 102 may be positioned on the front substrate 101 to implement red, green, and blue colors. The color filter 102 may include a plurality of pixels each including red, green, and blue subpixels. Other configurations of the subpixels may be used for the pixel. For example, each pixel may include red, green, blue, and white subpixels. When light is incident on the color filter 102, images corresponding to the red, green, and blue colors may be displayed.
A predetermined transistor 103, for example, a thin film transistor (TFT) may be formed on the back substrate 111. The transistor 103 may turn on or off liquid crystals in each pixel. Thus, the front substrate 101 may be referred to as a color filter substrate, and the back substrate 111 may be referred to as a TFT substrate.
The display panel 100 may include a front polarizing film 3400 and a back polarizing film 3410. The front polarizing film 3400 may be positioned on a front surface of the front substrate 101 to polarize light passing through the display panel 100. The back polarizing film 3410 may be positioned on a back surface of the back substrate 111 to polarize light passing through the optical layer 110 positioned in the rear of the back substrate 111. In the embodiment disclosed herein, the front polarizing film 3400 may be referred to as a first front polarizing film, and the back polarizing film 3410 may be referred to as a second front polarizing film.
The liquid crystal layer 104 may be formed of a plurality of liquid crystal molecules, and the arrangement of the liquid crystal molecules may change in response to a driving signal supplied by the transistor 103. Hence, light provided by the backlight unit may be incident on the color filter 102 in response to the molecular arrangement of the liquid crystal layer 104.
As a result, the color filter 102 may implement red, green, and blue light, and thus a predetermined image may be displayed on the front substrate 101 of the display panel 100.
As shown in
The TFT 103 supplies a data voltage supplied through the data lines 300 to a pixel electrode 320 of a liquid crystal cell Clc in response to a gate pulse from the gate lines 310. The liquid crystal cell Cle is driven by an electric field generated by a voltage difference between a voltage of the pixel electrode 320 and a common voltage Vcom applied to a common electrode 330, thereby controlling an amount of light passing through a polarizing plate. A storage capacitor Cst is connected to the pixel electrode 320 of the liquid crystal cell Clc and holds a voltage of the liquid crystal cell Clc.
Since the above-described structure and the above-described configuration of the display panel 100 are only one example, they may be changed, added, or omitted.
As shown in
When the bracket 140 is attached to the back surface of the back substrate 111 using the adhesive layer 400, a supporting member such as a pem nut and a boss and a fastening member such as a screw are not used. Therefore, a fixing process may be simply performed, the manufacturing cost may be reduced, and the thickness of the display device may be reduced.
A groove 141 may be formed in one surface of the bracket 140 facing the back substrate 111, so as to improve an adhesive strength between the bracket 140 and the back substrate 111. It may be preferable that the adhesive layer 400 is formed in the groove 141. The groove 141 of the bracket 140 may be referred to as a first groove. In this instance, because the groove 141 may prevent from an adhesive material of the adhesive layer 400 from being discharged to the outside of the bracket 140, an attaching process may be easily performed.
When the bracket 140 is attached to the back surface of the back substrate 111, the display panel 100 may include a portion W1 extending further than the bracket 140 in a longitudinal direction of the display panel 100.
As shown in
More specifically, the groove 141 of the bracket 140 may include portions A1 and A2 each having a gradually decreasing or increasing depth in a width direction WD, so as to further improve the adhesive strength between the bracket 140 and the back substrate 111 while efficiently injecting the adhesive material of the adhesive layer 400 into the groove 141.
For example, a depth t1 of a middle portion of the groove 141 may be different from a depth t2 of an edge portion of the groove 141. A length of the groove 141 in the edge portion of the groove 141 may gradually decrease.
In other words, the adhesive layer 400 formed in the groove 141 may include portions having each a different thickness. For example, a width of a middle portion of the adhesive layer 400 may be greater than a width of an edge portion of the adhesive layer 400.
The bracket 140 may include a portion having different widths. More specifically, the bracket 140 may include a portion having different widths as measured in the longitudinal direction of the display panel 100, i.e., the horizontal direction. In other words, the bracket 140 may include a portion having a gradually deceasing width as the bracket 140 goes in the direction away from the display panel 100.
As shown in
Preferably, the optical layer 110 may be fixed to the bracket 140 in the inner area IA of the bracket 140. When the optical layer 110 is fixed to the bracket 140, a portion of the optical layer 110 may overlap the bracket 140. In other words, the portion of the optical layer 110 may be positioned inside the bracket 140 or contact the bracket 140.

As shown in
An edge of the front surface of the front substrate 101 or an edge of the side of the front substrate 101 may be exposed in a state where the back cover 130 is fixed to the bracket 140. The exposure of the edge of the front surface of the front substrate 101 may indicate that an edge of a front surface of the front polarizing film 3400 attached to the front substrate 101 is exposed such that no components are in front, and that components such as glass, for example, are omitted.
The exposure of the edge of the front surface of the front substrate 101 may indicate that no elements are in front such that an observer can view the edge of the front surface of the front substrate 101 when the observer in the front of the display panel 100 views the front surface of the front substrate 101, i.e., when the observer in the front of the display panel 100 views the display panel 100 in a direction D2. The exposure of the edge of the side of the front substrate 101 may indicate that the observer can view the edge of the side of the front substrate 101 when the observer in the side of the display panel 100 views the front surface of the front substrate 101, i.e., when the observer in the side of the display panel 100 views the display panel 100 in a direction D1.
As above, when the edge of the front surface of the front substrate 101 or the edge of the side of the front substrate 101 is exposed after the back cover 130 is fixed to the bracket 140, the front substrate 101 may be formed of a tempered glass. In this instance, even if the edge of the front surface of the front substrate 101 or the edge of the side of the front substrate 101 is exposed, the front substrate 101 may be prevented from being damaged by an external impact.
As shown in
In this instance, when the observer in the front of the display panel 100 views the display panel 100, the observer may observe almost the entire area of the display panel 100. Hence, an attractive appearance of the display panel 100 may be provided. Further, because another edge of the side of the display panel 100 may not be showed to the observer, a visual effect, in which the observer may feel that the screen size of the display panel 100 is greater than the real screen size of the display panel 100, may be obtained.
In this instance, the edge of the front surface of the front substrate 101 and the edge of the side of the front substrate 101 in each of an upper part ({circle around (1)}) and a lower part ({circle around (2)}) of the display panel 100 may be exposed.
It can be seen from
A blocking member 1500 may be positioned at the edge of the front surface of the front substrate 101. Preferably, the blocking member 1500 may be attached to the edge of the front surface of the front substrate 101. Because the blocking member 1500 hides a dummy area positioned outside an active area of the display panel 100 on which an image is displayed, the image displayed on the active area may be more prominently showed.
The blocking member 1500 may have lightness lower than ambient lightness. For example, the lightness of the blocking member 1500 may be lower than lightness of the display panel 100. For this, the blocking member 1500 may be substantially black. For example, the blocking member 1500 may be substantially a black tape and may be formed by attaching a black tape to the front surface of the front substrate 101. Thus, the blocking member 1500 may be referred to as a black layer.
Because the blocking member 1500 is positioned on the front surface of the front substrate 101 and the edge of the front surface of the front substrate 101 is exposed, almost the entire portion of the blocking member 1500 may be exposed as shown in
Because the bracket 140 does not display the image, it may be preferable that the bracket 140 is positioned in the dummy area outside the active area. Further, it may be preferable that the bracket 140 is hidden by the blocking member 1500. Hence, as shown in FIG. 15, the blocking member 1500 may overlap the bracket 140. Preferably, the bracket 140 may entirely overlap the bracket 140. More preferably, widths W10 and W20 of the blocking member 1500 may be greater than widths W11 and W12 of the bracket 140. In this instance, the blocking member 1500 may include portions P1 and P2 extending further than the bracket 140 in a middle direction of the front substrate 101. Further, the blocking member 1500 may include portions W1 and W2 extending further than the bracket 140 in the opposite direction of the middle direction of the front substrate 101.
The widths W10 and W20 of the blocking member 1500 and the widths W11 and W12 of the bracket 140 may be a width in a cross section of the display panel 100.
As shown in
In this instance, the frame 1600 may be fixed to the bracket 140. More specifically, as shown in
Even in this case, as shown in
Alternatively, unlike the structure illustrated in
When the frame 1600 is positioned in the rear of the backlight unit, the back cover 130 may be omitted.
Alternatively, when the frame 1600 is positioned in the rear of the backlight unit, the size of the back cover 130 may be reduced.
As shown in
As shown in
In this instance, the edge of the front surface of the front substrate 101 may be exposed, and the edge of the side of the front substrate 101 may not be exposed. Hence, the edge of the side of the front substrate 101 may be efficiently protected from the external impact.
As shown in
In other words, the fact that the edge of the side of the front substrate 101 is hidden by the bracket 140 may mean that the bracket 140 overlaps the entire side or the partial side of the display panel 100 (for example, the entire side or the partial side of the back substrate 111 or the entire side or the partial side of the front substrate 101) in the longitudinal direction of the display panel 100.
Further, as shown in
Even if the bracket 140 hides the portion of the edge of the front surface of the front substrate 101, the bracket 140 may not hide the entire edge of the front surface of the front substrate 101. For example, as shown in
Alternatively, as shown in
Alternatively, as shown in
The above-described structure illustrated in
As shown in
Even when the bracket 140 hides the portion of the blocking member 1500, the size of the overlap portion P3 between the bracket 140 and the blocking member 1500 may be less than the size of a non-overlap portion between the bracket 140 and the blocking member 1500. For example, the size of the portion P3 of the blocking member 1500 hidden by the bracket 140 may be less than the size of a portion W100 of the blocking member 1500 that is not hidden by the bracket 140 and is exposed.
Further, as shown in
Alternatively, as shown in
Alternatively, as shown in
The above-described structure illustrated in
As shown in
One side of the auxiliary bracket 2300 may be fixed to the bracket 140, and the other side of the auxiliary bracket 2300 may be fixed to the back cover 130. In other word, auxiliary bracket 2300 provided adjacent to the brackets 140.
The auxiliary bracket 2300 may have a groove 2310, that is depressed in a direction toward the bracket 140, so as to fix the back cover 130 to the auxiliary bracket 2300. An end of the back cover 130 may be inserted into the groove 2310. The groove 2310 of the auxiliary bracket 2300 used to fix the back cover 130 may be referred to as a fourth groove.
When the back cover 130 is fixed to the auxiliary bracket 2300, the back cover 130 and the light source 120 (i.e., the back cover 130 and the backlight unit) may be separated from each other by a predetermined distance. This structure may be substantially the same as the structure illustrated in
Even when the back cover 130 is fixed to the auxiliary bracket 2300, the edge of the front surface of the front substrate 101 or the edge of the side of the front substrate 101 may be exposed. This structure was described above with reference to
As shown in
The bracket 140 and the auxiliary bracket 2300 may be coupled with each other using a predetermined coupling member. For example, as shown in
As shown in
More specifically, the auxiliary bracket 2300 may extend to the side of the display panel 100. For example, the auxiliary bracket 2300 may extend to the side of the back substrate 111 of the display panel 100 and thus may include a portion positioned on the side of the back substrate 111. Alternatively, the auxiliary bracket 2300 may extend to the side of the front substrate 101 of the display panel 100 and thus may include a portion positioned on the side of the front substrate 101.
As shown in
In this instance, the partial edge of the front surface of the front substrate 101 may be hidden by the auxiliary bracket 2300, but almost the entire front surface of the front substrate 101 may be exposed.
Even when the auxiliary bracket 2300 hides the partial edge of the front surface of the front substrate 101, all of the edges of the front surface of the front substrate 101 may not be hidden by the auxiliary bracket 2300. This structure may be substantially the same as the structure illustrated in
Further, when the auxiliary bracket 2300 extends to the front surface of the front substrate 101, the auxiliary bracket 2300 may include a portion P4 overlapping the blocking member 1500 on the front surface of the front substrate 101. In this instance, the auxiliary bracket 2300 may hide a portion of the blocking member 1500. The overlap portion P4 between the auxiliary bracket 2300 and the blocking member 1500 may contact the blocking member 1500.
Even when the auxiliary bracket 2300 hides the portion of the blocking member 1500, a size of the overlap portion P3 between the auxiliary bracket 2300 and the blocking member 1500 may be less than a size of a non-overlap portion between the auxiliary bracket 2300 and the blocking member 1500. The structure of the auxiliary bracket 2300 may be substantially the same as the structure illustrated in
The bracket 140 may be divided into a plurality of parts. For example, as shown in
The first brackets 140A1 and 140A2 may be respectively attached to long sides LS1 and LS2 of the back surface of the back substrate 111 of the display panel 100. The second brackets 140B1 and 140B2 may be respectively attached to short sides SS1 and SS2 of the back surface of the back substrate 111.
The first brackets 140A1 and 140A2 may be separated from the second brackets 140B1 and 140B2 by a predetermined distance d10. Preferably, the first brackets 140A1 and 140A2 and the second brackets 140B1 and 140B2 may be separated from each other in the corner of the back surface of the back substrate 111. In this instance, a process for attaching the first brackets 140A1 and 140A2 and the second brackets 140B1 and 140B2 to the back substrate 111 may be easily performed, and the manufacturing cost of the bracket 140 may be reduced. Hence, the manufacturing cost of the display device may be reduced.
The optical layer 110 may be fixed to the first brackets 140A1 and 140A2, the second brackets 140B1 and 140B2, or both. For example, as shown in
In this instance, widths A10 of the first brackets 140A1 and 140A2 may be different from widths A20 of the second brackets 140B1 and 140B2. Preferably, as shown in
Alternatively, as shown in
The first brackets 140A1 and 140A2 may be connected to the second brackets 140B1 and 140B2 using a predetermined connecting part. For example, as shown in
As shown in
As shown in
As shown in
Preferably, the width L10 of the front polarizing film 3400 may be greater than the width L11 of the back polarizing film 3410. In other words, an end of at least one side of the front polarizing film 3400 may extend further than the back polarizing film 3410.
More specifically, as shown in
Further, the front polarizing film 3400 may be separated from an end of the front surface of the front substrate 101 by a predetermined distance d12. In this instance, a process for attaching the front polarizing film 3400 to the front substrate 101 may be easily performed, and the production yield may be improved.
As shown in
Further, the front polarizing film 3400 may include a portion Y1 extending further than the blocking member 1500 in an outside direction of the display panel 100.
Alternatively, as shown in
As shown in
As shown in
When the auxiliary bracket 2300 includes a portion positioned on the side of the display panel 100, the front polarizing film 3400 and the auxiliary bracket 2300 may be separated from each other by a predetermined distance d22 on the front surface of the front substrate 101. This may be equally applied to the structure in which the auxiliary bracket 2300 is not used and the bracket 140 includes a portion positioned on the side of the display panel 100.
As shown in (a) and (b) of
For example, the first short side SS1 of the front substrate 101 may extend further than the first short side SS1 of the back substrate 111 corresponding to the first short side SS1 of the front substrate 101 by a first length S1. The second short side SS2 of the front substrate 101 may extend further than the second short side SS2 of the back substrate 111 corresponding to the second short side SS2 of the front substrate 101 by a second length S2.
The first length S1 may be substantially equal to the second length S2. Alternatively, the first length S1 may be different from the second length S2. In this instance, the structure of the first short side SS1 of the front substrate 101 may be different from the structure of the second short side SS2 of the front substrate 101.
For example, a sufficient space may be provided in the first short side SS1 of the back substrate 111, so as to mount a gate driver on the first short side SS1 of the back substrate 111 corresponding to the first short side SS1 of the front substrate 101. In this instance, the first length S1 may be less than the second length S2.
Further, the first long side LS1 of the front substrate 101 may extend further than the first long side LS1 of the back substrate 111 corresponding to the first long side LS1 of the front substrate 101 by a length S10. The second long side LS2 of the front substrate 101 may extend further than the second long side LS2 of the back substrate 111 corresponding to the second long side LS2 of the front substrate 101 by a length S20. The length S10 and the length S20 may be different from each other.
When the long sides LS1 and LS2 and the short sides SS1 and SS2 of the front substrate 101 extend further than the long sides LS1 and LS2 and the short sides SS1 and SS2 of the back substrate 111, respectively, a distance X1 between the front substrate 101 and the auxiliary bracket 2300 may be different from a distance X2 between the back substrate 111 and the auxiliary bracket 2300 as shown in
This may be equally applied to the structure in which the auxiliary bracket 2300 is not used and the bracket 140 includes the portion positioned on the side of the display panel 100.
At least one of a gate driver for supplying a driving signal to the gate lines and a data driver for supplying a driving signal to the data lines may be mounted outside the back substrate 111. The gate driver may include a plurality of gate driver integrated circuits (ICs), and the data driver may include a plurality of source driver ICs.
For example, as shown in
It may be preferable that the gate driver 3900 and the data driver 3910 are formed on the back substrate 111 in a dummy area DA positioned outside an active area AA on which the image is displayed.
In this instance, because circuit elements required to display the image may be directly formed on the back substrate 111, the number or the size of circuit boards positioned outside may be reduced. Hence, the size or the thickness of the display device may be further reduced.
As shown in
The first transistor 103, for example, the first TFT 103 capable of turning on or off the liquid crystals in each pixel may be formed on the back substrate 111. The gate driver 3900 or the data driver 3910 may include a second transistor that is positioned in the area OVA commonly overlapping the front substrate 101 and the back substrate 111 outside the seal portion 200. Namely, the first transistor 103 may be positioned inside the seal portion 200, and the second transistor may be positioned in the area OVA commonly overlapping the front substrate 101 and the back substrate 111 outside the seal portion 200.
As shown in
As shown in
In this instance, as shown in
For example, the driving board 1900 for supplying the driving signal to the display panel 100 may be positioned outside the display panel 100, for example, between the frame 1600 and the back cover 130.
In this instance, a connector 4310 may be positioned on the driving board 1900. One terminal of a connection substrate 4320 including an electrode 4330 may be connected to the connector 4310, and the other terminal may be connected to the pad electrode 4300. Hence, the driving board 1900 and the pad electrode 4300, more specifically, the driving board 1900 and the data driver 3910 may be electrically connected to each other. The connection substrate 4320 may be a flexible substrate such as a tape carrier package (TCP) and a flexible printed circuit (FPC).
As above, the connection substrate 4320 may be connected to the pad electrode 4300 in a formation portion of the pad electrode 4300. The length of the front substrate 101 may be greater than the length of the back substrate 111, so that the connection substrate 4320 is not seen in the front of the display panel 100. In other words, when the pad electrode 4300 is formed on the second long side LS2 of the back substrate 111, the length S20 may be greater than the length S10.
As shown in
A first transfer line 4400 may be formed between the first pad electrode 4300A and the gate driver 3900 to transfer a driving signal, that is received from a driving board (not shown) through the first connection substrate 4320A, to the gate driver 3900. A second transfer line 4410 may be formed between the second pad electrode 4300B and the data driver 3910 to transfer a driving signal, that is received from a driving board (not shown) through the second connection substrate 4320B, to the data driver 3910.
As shown in
The active area AA may be formed in an area overlapping the optical layer 110 positioned in the inner area IA of the bracket 140. Hence, it may be preferable that the seal portion 200 for sealing the liquid crystal layer 104 is positioned in the inner area IA of the bracket 140. More specifically, the seal part 200 may be separated from the bracket 140 by a predetermined distance C1 in the longitudinal direction of the back substrate 111.

When the length of the front substrate 101 is greater than the length of the back substrate 111 by a predetermined length C10, the blocking member 1500 may be positioned on the back surface of the front substrate 101. In this instance, the blocking member 1500 positioned on the back surface of the front substrate 101 may be prevented from being exposed to the front surface of the front substrate 101 while hiding the back substrate 111 positioned outside the seal portion 200. Hence, a good appearance of the display device may be provided.
The end of the front substrate 101 may extend further than the blocking member 1500 in the outside direction of the display panel 100 by a predetermined distance, so as to easily perform an attaching process of the blocking member 1500 and increase the production yield and the blocking efficiency. The blocking member 1500 may extend further than the end of the back substrate 111 by a predetermined distance C20.
The back cover 130 and the auxiliary bracket 2300 are coupled with each other using a coupling member.
For example, as shown in
A hole 4710 may be formed in the back cover 130, and a hole 4720 corresponding to the hole 4710 of the back cover 130 may be formed in the auxiliary bracket 2300. In this instance, the second coupling member 4700 may pass through the hole 4710 of the back cover 130 and then may be fixed to the hole 4720 of the auxiliary bracket 2300. Hence, the back cover 130 may be fixed to the auxiliary bracket 2300.

An active retarder 14 may be positioned in the front of the display panel 100, thereby causing a 3D image to be displayed on the display panel 100. The active retarder 14 may be attached to a front surface of the display panel 100 using a transparent adhesive or may be coupled with the front surface of the display panel 100 using a structure.
The active retarder 14 controls a tilting angle of liquid crystals, first-circularly polarizes light coming from the display panel 100, and transmits the first circularly polarized light. Alternatively, the active retarder 14 controls a tilting angle of liquid crystals, second-circularly polarizes light coming from the display panel 100, and transmits the second circularly polarized light. The first circularly polarized light and the second circularly polarized light are perpendicular to each other. A left eye image and a right eye image are alternately displayed on the display panel 100 every one frame. The active retarder 14 first-circularly polarizes the left eye image and second-circularly polarizes the right eye image in synchronization the display timing.
A left eye glass of glasses a viewer uses includes a first circular polarizing filter, and a right eye glass of the glasses includes a second circular polarizing filter. Hence, the viewer views only the first circularly polarized left eye image through his or her left eye and views only the second circularly polarized right eye image through his or her right eye. As a result, the display device according to the embodiment of the invention implements a binocular disparity in a time division driving manner, thereby displaying the 3D image.
A filter 12 may be positioned in the front of the display panel 100. Preferably, the filter 12 may be laminated on the front surface of the display panel 100. The filter 12 may be exposed to the outside and may protect the display panel 100 forming an external appearance from a mechanical damage such as a scratch. The filter 12 may include an opaque layer 12a positioned at an edge of the filter 12 and a transparent layer 12b positioned inside the filter 12. The opaque layer 12a is positioned at a location substantially corresponding to a non-display area (i.e., a dummy area) of the display panel 100, and the transparent layer 12b is positioned at a location substantially corresponding to an active area of the display panel 100. The transparent layer 12b may be omitted in the filter 12.
The opaque layer 12a prevents the bracket 140 from being seen outside the display panel 100. Further, because the opaque layer 12a has as the same color as the bracket 140, when the display panel 100 is turned off, the display panel 100 and the bracket 140 looks like one part. In other words, because the user perceives the display panel 100 and the bracket 140 as one part, the opaque layer 12a may make the display panel 100 look larger than its actual size. The opaque layer 12a may be the blocking member.
The bracket 140 supports the display panel 100 and receives the backlight unit inside the bracket 140. The bracket 140 has a rectangular plane shape suitable for the shape of the display panel 100 and has a groove 13a formed in an inner wall thereof. A portion (i.e., one end) of the edge of the display panel 100 is received into the groove 13a of the bracket 140 and is fixed to the bracket 140. The optical layer 110 and the light source 120 are closely stacked in the rear of the bracket 140 with the bracket 140 interposed between the display panel 100 and the optical layer 110 and the light source 120.
The optical layer 110 may include a prism sheet 15a and a diffusion plate 15b. The optical layer 110 transfers light from the light source 120 to the display panel 100, thereby causing the image to be displayed on the display panel 100.
The back cover 130 may be formed of iron material, so as to improve the structural stability. The back cover 130 is coupled with the bracket 140 with the optical layer 110 and the light source 120 interposed between the back cover 130 and the bracket 140.
As shown in
The light source 120 may include a light emitting unit 17a and a support plate 1600. The light emitting unit 17a may have a direct type structure in which light sources, for example, light emitting diodes are mounted on a substrate. The support plate 1600 is a structure for structurally supporting the light emitting unit 17a and may be formed of aluminum with the good rigidity or iron material such as a steel sheet. The light emitting unit 17a is fixed to the support plate 1600 using an adhesive or a structure such as a bolt coupling. The support plate 1600 may be a frame.
One end of the support plate 1600 is fixed to the bracket 140 through a screw coupling between the support plate 1600 and a boss 13b of the bracket 140. The optical layer 110 is closely positioned and fixed between the light source 120 and the display panel 100. One end of the optical layer 110 may be fixed to the bracket 140 using an adhesive or a protrusion provided in the bracket 140, so as to prevent a movement of the optical layer 110. Furthermore, a fixer (not shown) for fixing the bracket 140 and the optical layer 110 is positioned between the bracket 140 and the optical layer 110. The fixer may remove a space between the bracket 140 and the optical layer 110, thereby fixing the optical layer 110.
As above, when the support pin 23 is used, the support plate 1600 used to support the light source 120 may be omitted. Therefore, a thickness of the backlight unit may be reduced.
As shown in
The light guide plate 110c guides light coming from the side of the light sources, thereby causing the light to be uniformly incident on the entire surface of the display panel 100. The reflection plate 110d reflects light travelling toward a bottom surface of the reflection plate 110d on a front surface of the reflection plate 110d on which the display panel 100 is formed.
The light guide plate 110c and the reflection plate 110d are sequentially stacked and are fixed using the support pin 23. One end of the support pin 23 is screw-coupled with the bracket 140, and the other end extends to the bottom of the reflection plate 110d. Hence, the optical layer 110 may be supported and fixed by the elastic force of the support pin 23.
A backlight unit 31 includes a light emitting diode 31b serving as a light source and a substrate 31a on which the light emitting diode 31b is mounted. The size of the substrate 31a and the number of light emitting diodes 31b may vary. The backlight unit 31 may be fixed to a receiving groove 131a using an adhesive. The receiving groove 131a may prevent a leakage of light. The receiving groove 131a may be omitted as shown in
The thickness of the module having the edge-type backlight unit may be less than the thickness of the module having the direct type backlight unit.
As shown in
The display panel 61 displaying an image is exposed to a front surface of the display device to form an external appearance of the display device. A filter 62 including a transparent 62a and an opaque layer 62b and an active retarder 66 making a 3D image may be selectively positioned in the front of the display panel 61.
The first bracket 63 supports the display panel 61 and receives the optical layer 65 and the backlight unit 67 therein. The first bracket 63 has a E-shape in which a lower portion of the first bracket 63 is open, so that the first bracket 63 can support three portions of the display panel 61. A recess is formed in an inside wall of the first bracket 63 and supports the display panel 61.
The optical layer 65 and the backlight unit 67 are sequentially stacked and closely positioned in the rear of the display panel 61 with the first bracket 63 interposed between the display panel 61 and the optical layer 65 and the backlight unit 67.
The second bracket 64 is positioned under a module.
As shown in
An electrode 711 for sensing changes in a capacitance may be formed on an inside surface of one end of the display panel 61. The electrode 711 may be formed of a transparent conductive material and may have a diamond cell structure of a lattice shape. When the user indirectly touches the electrode 711 with the display panel 61 interposed between the user and the electrode 711, a capacitance at a touch position varies. The capacitance at the touch position is then transferred to a controller 713. A row coordinate and a column coordinate of the touched electrode lattice are read, and the touch position is understood. The controller 713 generates a control signal corresponding to the touch position and thus may control an operation of the display device. The controller 713 turns up or down the volume of the display device based on the touch position and thus may control an operation of the display device.
It is preferable that only one of the upper substrate and the lower substrate exists and an electrode is formed on a back surface of the remaining substrate, so as to increase the touch sensitivity of the electrode 711.
The controller 713 connected through above-described electrode 711 serving as a touch sensor and a signal line 715, a speaker 71, a remote control receiving module (not shown), etc. may be positioned inside the second bracket 64. The display device having the slim structure may be manufactured by disposing the functional modules inside the second bracket 64. Hence, the space of the display device may be efficiency used.
The second bracket 64 may be screw-coupled with the back cover 69 and may be fixed to the back cover 69. As shown in
As shown in
The plurality of light sources 6120 are formed on the first layer 6110, and the second layer 6130 is formed on the first layer 6110 to cover the plurality of light sources 6120.
The first layer 6110 may be a substrate on which the light sources 6120 are mounted. An electrode pattern (not shown) for connecting the light sources 6120 is formed on the first layer 6110. The first layer 6110 may be a metal printed circuit board (PCB) obtained by forming an insulating layer using a metal such as aluminum in which electric current does not flow.
The light sources 6120 may be one of a light emitting diode (LED) chip and a LED package having at least one LED chip. It is preferabelt that the light sources 6120 are a side view type LED package in which a light emitting surface is formed to face the side surface. The light sources 6120 emit red, green, and blue light, or may emit white light.
The second layer 6130 is formed on the first layer 6110 to cover the light sources 6120. The second layer 6130 transmits and diffuses light emitted from the light sources 6120, thereby causing the light sources 220 to uniformly provide the light to the display panel.
A reflection layer 6140 for reflecting the light from the light sources 6120 may be formed between the first layer 6110 and the second layer 6130, more particularly, on the first layer 6110. The reflection layer 6140 again reflects light totally reflected from a boundary between the second layer 6130 and the reflection layer 6140, thereby more widely diffusing the light emitted from the light sources 6120.
The reflection layer 6140 may use a sheet in which a white pigment, for example, titanium oxide is dispersed, a sheet in which a metal deposition layer is stacked on the surface of the sheet, a sheet in which bubbles are dispersed so as to scatter light, etc. among various types of sheets formed of synthetic resin material. The surface of the reflection layer 6140 may be coated with silver (Ag) so as to increase a reflectance. The reflection layer 6140 may be coated on the first layer 6110. The second layer 6130 may be formed of a light transmissive material, i.e., silicon or an acrylic resin. Other materials may be used for the second layer 6130.
The second layer 6130 may be formed of a resin, that is capable of diffusing the light from the light sources 6120 and has a refractive index of approximately 1.4 to 1.6, so that the optical assembly 6101 has the uniform luminance.
The second layer 6130 may be formed by applying and curing a liquid or gel-type resin on the first layer 6110 and the plurality of light sources 6120. Alternatively, the second layer 6130 may be separately fabricated and then may be attached on the first layer 6110.
As a thickness of the second layer 6130 increases, the second layer 6130 more widely diffuses the light emitted from the light sources 6100. Hence, the light sources 6100 may provide the light having the uniform luminance to the display panel. On the other hand, as the thickness of the second layer 6130 increases, an amount of light absorbed in the second layer 6130 increases. Hence, the luminance of light which the optical assembly 6101 provides to the display panel may entirely decrease. Accordingly, the thickness of the second layer 6130 may be approximately 0.1 mm to 4.5 mm, so that the backlight unit 6100 can provide light having the uniform luminance to the display panel without a reduction in the luminance.
As shown in
For example, the adjacent light sources 6120 positioned on the left and right sides of the first light source 6120 emit light in the same direction (in an arrow direction in
As above, because the LEDs 6120 and 6121 emit light in the opposite directions along the line, the luminance of light may be prevented from being concentrated or reduced in a predetermined region of the optical assembly 6101.
The optical assemblies 6101 thus formed may form a light source module 6100. The light source module 6100 may be driven in a global dimming method, a local dimming method, an impulsive driving method, or other driving methods.
For example, the light source module 6100 may be divided into a plurality of driving regions and may operate. The display quality, for example, the contrast ratio and the clarity of the image may be improved by driving the light source module 6100 so that luminances of the driving regions of the light source module 6100 are equal to a luminance of an image signal. Accordingly, the light source module 6100 may be manufactured by assembling a plurality of components. For example, as shown in
A region of the display panel corresponding to one optical assembly 6101 may be divided into two or more blocks, and the display panel and the light source module 6100 may be separately driven by the unit of a block. As above, when the light source module 6100 is configured using the plurality of optical assemblies 6101, a manufacturing process of the light source module 6100 may be simplified and a loss generated in the manufacturing process may be minimized. Further, the light source module 6100 has an advantage applicable to backlight units having various sizes through mass production by standardizing the optical assemblies 6101.
Furthermore, when some of the LEDs included in the light source module 6100 have a failure, only the optical assembly having the failure has only to be replaced without replacing the light source module 6100. Therefore, a replacing work may be easily performed and the part replacement cost may be saved.

As shown in
As above, when the optical layer 110 is disposed on the fixing part 6600, the size of a contact surface between the optical layer 110 and the fixing part 6600 may be relatively small. Therefore, a damage of the optical layer 110 may be prevented.
The fixing part 6600 contacting the optical layer 110 may be tender than the bracket 140, so as to suppress the movement of the optical layer 110 and to sufficiently prevent the damage of the optical layer 110. For example, the fixing part 6600 may contain polyurethane.
A light guide plate 7000 may be disposed in the rear of the optical layer 110. In this instance, the backlight unit may include an edge type light source, the optical layer 110, the light guide plate 7000, and a frame. When the backlight unit includes the light guide plate 7000, the edge type light source may be disposed on the side of the light guide plate 7000.
A maximum height Z2 of the optical layer 110 may be less than a height Z3 of the bracket 140 as measured from the back surface of the back substrate 111, so as to prevent the movement of the optical layer 110.
When the light guide plate 7000 is disposed in the rear of the optical layer 110, a maximum height Z4 of the light guide plate 7000 may be less than the height Z3 of the bracket 140 as measured from the back surface of the back substrate 111, so as to prevent the movement of the light guide plate 7000.

In the embodiment disclosed herein, the air gap 6500 formed between the back substrate 111 and the optical layer 110 is referred to as a first air gap, and the air gap 7200 formed between the frame 1600 and the back cover 130 is referred to as a second air gap. A thickness Z5 of the second air gap 7200 may be greater than a thickness Z1 of the first air gap 6500.

As shown in
The bracket 140 may be separated from the auxiliary bracket 2300 by a predetermined distance Z10 in a longitudinal direction D31 of the display panel 100. Namely, an air gap may be formed between the bracket 140 and the auxiliary bracket 2300 in the longitudinal direction D31 of the display panel 100. In other words, the bracket 140 may be separated from the side cover 2300 in the longitudinal direction D31 of the display panel 100. Hence, the attractive appearance of the display device may be provided, and the entire weight of the display device may be reduced. Further, because the auxiliary bracket 2300 is prevented from contacting the display panel 100, the damage of the display panel 100 may be prevented.
In other word, the auxiliary bracket 2300 includes a sidewall 2330 and an overhang portion 2300A extending in the horizontal direction DRH a first end portion of the sidewall 2330 covers the sides of the front and back substrates 101, 111.

For example, the adhesive layer 400 may be formed using a double sided adhesive tape as the adhesive sheet.
As shown in
Because the edge of the front surface of the front substrate 101 may be exposed in the display device according to the embodiment of the invention, the thickness Z11 of the front substrate 101 may increase so as to prevent the damage of the front substrate 101. In this instance, the thickness Z11 of the front substrate 101 may be greater than the thickness Z10 of the back substrate 111.
