Hereinafter, embodiments according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a view illustrating a touch control device according to an embodiment of the present disclosure.

A touch control device 100 according to the embodiment of the present disclosure may include a touch unit 101.

The touch unit 101 may be formed in a certain area capable of receiving a touch signal of the user. For example, as shown in the drawings, the touch unit 101 may be provided in a concave curved surface shape of different curvatures. Alternatively, the touch unit 101 may be provided in a convex curved surface shape of different curvatures, and may not be limited thereto. Curvatures may be provided larger than that shown in the drawings. Further, the touch unit 101 may be provided not as a curved surface but as a polygonal surface. In addition, although the touch unit 101 is illustrated as being circular, the touch unit 101 may be polygonal or elliptical.

The touch unit 101 may be a touch pad to which a signal is input when the user contacts it with a pointer, such as his/her finger or a touch pen. The user may input a desired instruction or command by inputting a predetermined touch gesture to the touch unit 101.

Recognizing the pointer's position while the pointer is not contacting but approaching the touch pad is called ‘proximity touch,’ and recognizing the pointer's position when the pointer contacts the touch pad is called ‘contact touch.’ Proximity touch is made by recognizing a position on the touch pad vertically corresponding to a position in the air where the pointer approaches the touch pad.

The touch unit 101 may use capacitive methods.

The touch unit 101 may be installed on the inner side of a border part 102. The border part 102 may refer to a part that encloses the touch unit 101, and may be formed of a separate member from that of the touch unit 101. As shown in FIG. 9, gradations that can be felt by the sense of touch are formed on the border part 102, so that the user can intuitively know a swype angle (or distance). Therefore, by making it possible to input different signals according to the swype angles (or distances), the degree of freedom of manipulation can be improved, and the input accuracy can be improved.

As described above, the border part 102 may be provided to receive a swype input of the user. The touch unit 101 may be provided to receive a gesture input of the user. The swype input denotes an action of inputting a gesture clockwise or counterclockwise without taking the pointer off the border part 102. The gesture input denotes an action of inputting a straight line or a curved line gesture without taking the pointer off the touch unit 101.

FIG. 2 is an exploded perspective view of the touch control device according to the embodiment of the present disclosure.

As shown in FIG. 2, the touch control device 100 according to the embodiment of the present disclosure includes a base 110 having a metal complex, electrode grooves 113a, 113b, 113c formed in a touch area 111 of the base 110 (see FIG. 6), sensor electrodes 120 formed on the electrode grooves 113 by a plating or deposition process, via holes 114 penetrating the base 110, connection electrodes 123 connecting the sensor electrodes 120 through the via holes 114 and an integrated circuit 130 coupled to the base 110 and connected to the sensor electrodes 120 to sense a change in capacitance of each of the sensor electrodes 120.

The base 110 may include a metal complex. This is to form the sensor electrodes 120 by the LDS (Laser Directing Structure) method. The LDS method refers to a method of forming a conductive structure in a region of a support member exposed to a laser by forming the support member with a material including a non-conductive and chemically stable metal complex, exposing a metal seed by exposing a portion of the supporting member to a laser, such as an Ultra Violet (UV) laser or Excimer laser to break the chemical bond of the metal complex, and metalizing the supporting member.

The base 110 may include the touch area 111 used as a touch pad and a peripheral portion 112 extending downward from an outer edge of the touch area 111.

The electrode grooves 113 may be formed in the touch area 111 of the base 110. The electrode grooves 113 may be formed by irradiating the base 110 with a laser. The electrode grooves 113 may be formed on an upper surface and a lower surface of the touch area 111, respectively. This is to form the sensor electrodes 120 and the connection electrodes 123 by a plating or deposition process.

The sensor electrodes 120 or the connection electrodes 123 may be formed on the electrode grooves 113 after a plating or deposition process.

That is, the sensor electrodes 120 (see FIG. 3) may be formed on the base 110 using the LSD (Laser Directing Structure) method.

The sensor electrodes 120 include a conductive material and may be metal, for example. Copper (Cu) may be used among metals in consideration of conductivity and cost. The sensor electrodes 120 may be formed of metal such as gold (Au) in addition to copper.

The via holes 114 may be formed at the touch area 111 of the base 110. A plurality of the via holes 114 may be formed throughout the touch area 111. The via holes 114 may be formed before irradiating the base 110 with a laser. That is, the via holes 114 may be formed together with the base 110 when the base 110 is manufactured by injection molding or the like.

The via holes 114 may be in contact with the sensor electrodes 120. Considering the process order, the sensor electrodes 120 may be formed on the via holes 114.

The via holes 114 may connect the sensor electrodes 120 which are separated from each other. For this, the connection electrodes 123 may be formed on the bottom surface of the base 110. A detailed description thereof will be described later.

The integrated circuit 130 may be coupled to the bottom of the base 110. The integrated circuit 130 includes a printed circuit board 131, terminal portions 126 disposed at a predetermined distance from the printed circuit board 131 along an edge of the printed circuit board 131, and a sensor IC 133 mounted on the printed circuit board 131. When the integrated circuit 130 is coupled to the base 110, the terminal portions 126 are connected to terminal electrodes 124 and 125, and the sensor electrodes 120 are electrically connected to the sensor IC 133.

A support unit 150 may be provided under the base 110 and the integrated circuit 130. The support unit 150 may be configured to fix the base 110 and the integrated circuit 130, and is not an essential component. The support unit 150 may be configured to fix the touch control device 100 at a specific position such as the inside of a vehicle.

FIG. 3 is a view illustrating a base of the touch control device according to the embodiment of the present disclosure and FIG. 4 is an enlarged view of ‘A’ shown in FIG. 3 and FIG. 5 is a bottom view of the base shown in FIG. 3 and FIG. 6 is a cross-sectional view taken along line B-B′ of FIG. 4.

The sensor electrodes 120 of the present disclosure will be described in detail with reference to FIG. 3 to FIG. 6.

According to the embodiment of the present disclosure, the sensor electrodes 120 may be formed on the upper surface of the touch area 111 of the base 110. As described later, the sensor electrodes 120 may be formed on the lower surface of the touch area 111. In this case, a distance between the sensor electrodes 120 and the pointer is increased by a thickness of the base 110. Therefore, it is preferable that the sensor electrodes 120 are formed on the upper surface of the base 110.

The sensor electrodes 120 may be formed on the upper surface of the base 110 using the LDS (Laser Directing Structure) method as described above.

The sensor electrodes 120 may include first sensor electrodes 121 directly connected to the upper surface of the base 110 and second sensor electrodes 122 separated from the upper surface of the base 110. The first sensor electrodes 121 may be formed on first electrode grooves 113a (see FIG. 6) formed on the upper surface of the base 110 by a plating or deposition process. The second sensor electrodes 122 may be formed on second electrode grooves 113b (see FIG. 6) formed on the upper surface of the base 110 by a plating or deposition process.

The first sensor electrodes 121 may be transmitting electrodes (TX electrodes), and the second sensor electrodes 122 may be receiving electrodes (RX electrodes). Alternatively, the first sensor electrodes 121 may be receiving electrodes (RX electrodes), and the second sensor electrodes 122 may be transmitting electrodes (TX electrodes).

The first sensor electrodes 121 may be directly connected to the upper surface of the base 110. The first sensor electrodes 121 may be connected to each other even if separate connection electrodes are not provided. The first sensor electrodes 121 may be connected to each other along the first direction. The first sensor electrodes 121 are not connected to each other along the second direction perpendicular to the first direction. That is, the first sensor electrodes 121 may be separated from each other in the second direction.

The second sensor electrodes 122 may be separated from each other on the upper surface of the base 110. The second sensor electrodes 122 may be separated not only in the first direction but also in the second direction perpendicular to the first direction.

The first sensor electrodes 121 and the second sensor electrodes 122 may be disposed in a crossing manner along the second direction. That is, the first sensor electrodes 121 and the second sensor electrodes 122 may be alternately arranged along the second direction.

The via holes 114 may be formed on lower surfaces of the second sensor electrodes 122. According to the manufacturing process sequence of the touch control device 100, since the via holes 114 are formed together with the base 110 and the sensor electrodes 120 are formed on the base using the LDS method, the second sensor electrodes 122 are formed on upper surfaces of the via holes 114.

The second sensor electrodes 122 may be connected to each other through the via holes 114. Specifically, the second sensor electrodes 122 separated from each other may be connected by the connection electrodes 123 formed on the lower surface of the base 110. The connection electrodes 123 may be formed on third electrode grooves 113c (see FIG. 6) formed on the lower surface of the base 110 by a plating or deposition process.

As shown in FIG. 5, the connection electrodes 123 may connect the via holes 114 arranged adjacent to each other. The connection electrodes 123 may be formed on the lower surface of the base 110. The connection electrodes 123 may be formed on the lower surface of the base 110 by using the LDS method, like the sensor electrodes 120. The connection electrodes 123 and the second sensor electrodes 122 may be connected through the via holes 114.

A double layer (two-layer) structure in which RX electrodes and TX electrodes are formed on a first base and a second base arranged vertically may be used, but the manufacturing process of the double layer (two-layer) structure is complicated, and the productivity and durability of the double layer (two-layer) structure are relatively low. In addition, in the double layer (two-layer) structure, a material of an overlay cannot be selected because UV coating is performed on a base without attaching a separate overlay for protecting electrodes.

According to the embodiment of the present disclosure, it is possible to connect both RX electrodes and TX electrodes on a base having one layer. The RX electrodes and the TX electrodes are formed on one surface of the base, and the RX electrodes or the TX electrodes are connected to each other on the other surface of the base through via holes, which is also referred to as a 1.5 layer.

In the manufacturing process of the touch control device 100 according to the embodiment of the present disclosure, a laser is irradiated to the base 110, and the first sensor electrodes 121, the second sensor electrodes 122 and the connection electrodes 123 are formed by a plating or deposition process. Therefore, compared to a manufacturing process of the double-layered touch control device, the number of processes is greatly reduced, and thus the productivity can be greatly improved.

In the touch control device 100 according to the embodiment of the present disclosure, an overlay 140 may be attached to the upper surface of the base 110, and the overlay 140 may be made of any material having low conductivity. Accordingly, the overlay 140 exposed to the outside of the touch control device 100 may include various materials, which leads to an improvement in the degree of freedom of design. The overlay 140 may include materials capable of recognizing capacitive touch such as glass, acrylic, ABS, wood, stone, and the like. The materials listed above are merely examples and the materials of the overlay 140 are not limited as long as they are nonconductive materials capable of recognizing capacitive touch. However, it is preferable that the thickness of the overlay 140 is not too thick in consideration of the touch performance.

By providing the via holes 114, the overlay 140 can be uniformly attached to the upper surface of the base 110.

An adhesive layer 141 is disposed on the upper surface of the base 110 and then the overlay 140 is attached to the upper surface of the adhesive layer 141. Generally, air bubbles are generated between the overlay 140 and the adhesive layer 141 or between the adhesive layer 141 and the base 110 in a process of attaching the overlay 140. In order to remove the air bubbles, air is sucked from a side of the base 110, and the above-described attaching process is performed. However, if the upper surface of the base 110 has a curved surface shape of different curvatures, air bubbles are not easily removed even if air is sucked from the side of the base 110, which makes it difficult to uniformly attach the overlay 140 to the base 110.

According to the embodiment of the present disclosure, the plurality of via holes 114 may be formed at the touch area 111 of the base 110 and the plurality of via holes 114 may be formed through the upper and lower surfaces of the base 110. When the overlay 140 is attached, the plurality of via holes 114 becomes passages through which air bubbles can move. This solves the non-uniform adhesion problem of the overlay 140. Thus, the overlay 140 can be uniformly attached onto the base 110, which can lead to increased productivity and improved touch performance.

According to the embodiment of the present disclosure, the sensor electrodes 120 and the printed circuit board 131 are connected by simply contacting the base 110 and the printed circuit board 131 without fastening members. The sensor IC 133 is mounted on the printed circuit board 131 and the sensor electrodes 120 are connected to the sensor IC 133.

Specifically, the plurality of terminal portions 126 may be provided on the edge of the printed circuit board 131, and the plurality of terminal portions 126 may have a C CLIP structure.

A plurality of terminal engaging portions 132 may be provided on an inner side surface of the peripheral portion 112 of the base 110 and the plurality of terminal engaging portions 132 may be coupled to the plurality of terminal portions 126 of the printed circuit board 131.

The first terminal electrodes 124 to connect the first sensor electrodes 121 and the terminal portions 126, and the second terminal electrodes 125 to connect the second sensor electrodes 122 and the terminal portions 126.

The first terminal electrodes 124 are connected to the first sensor electrodes 121 through the via holes 114 and may extend from the lower surface of the base 110 to the terminal engaging portions 132.

The second terminal electrodes 125 are connected to the second sensor electrodes 122 through the via holes 114 and may extend from the lower surface of the base 110 to the terminal engaging portions 132.

The first terminal electrodes 124 and the second terminal electrodes 125 may be formed using the LDS method, like the sensor electrodes 120.

The first terminal electrodes 124 and the second terminal electrodes 125 may be formed on an upper surface and a side surface of the terminal engaging portions 132. The terminal portions 126 are in contact with the side surface of the terminal engaging portions 132. Therefore, the sensor electrodes 120 and the printed circuit board 131 are electrically connected by engagements of the terminal portions 126 and the terminal engaging portions 132.

As described above, in the touch control device 100 according to the embodiment of the present disclosure, the base 110 is coupled to the integrated circuit 130 including the printed circuit board 131 without fastening members. Conventionally, a robot solder process, which causes a decrease in productivity, was needed to connect the base and the printed circuit board. On the other hand, the touch control device 100 according to the embodiment of the present disclosure does not require the robot solder process, so productivity is improved and the manufacturing process can be simplified.

That is, the sensor electrodes 120 may be formed on the lower surface as well as the upper surface of the base 110.
