Description

Technical Field

[0001] This invention relates to the field of touch display technology, and more particularly to a touch panel and electronic device. Background Technology

[0002] In the laptop industry, in pursuit of thinner and lighter designs and superior aesthetics while maintaining overall manufacturing costs, current laptop casings typically use insulating non-metallic materials. During ESD reliability testing of the entire laptop, some test points are located in the gaps of the laptop casing. Therefore, there is a possibility that ESD can enter the laptop through these gaps, travel through the sheet metal components, and ultimately reach the metal traces in the touch area. This can lead to damage to the metal traces and touch failure. In particular, existing touch modules usually have their own sheet metal structure, and there is an overlapping area between the metal structure and the metal traces in the touch area. This area is a weak point in ESD protection, easily attracting static electricity, which can cause ESD to damage the metal traces and ultimately result in touch failure. Summary of the Invention

[0003] The present invention aims to solve at least one problem in the prior art. To this end, the present invention provides a touch panel and electronic device that have good electrostatic discharge performance.

[0004] According to a first aspect of the present invention, a touch panel includes a base and a touch module, a display module, and a cover plate disposed on the base. The base has a metal component disposed on one edge region. The touch module includes a touch area and a wiring area. The wiring area is disposed around the touch area and includes multiple metal wirings extending from the touch area. A ground wire is disposed around the metal wirings. An ink layer and a transparent protective layer are sequentially disposed above the metal wirings and the ground wire. The metal wirings and the projected pattern of the metal component in the vertical direction have an overlapping area. A ground wire compensation portion is disposed around the overlapping area. A cutout area is disposed above the ground wire compensation portion of the ink layer and the transparent protective layer.

[0005] Therefore, this solution provides a grounding compensation section around the overlapping area of ​​the vertical projection pattern of the metal trace and the metal component. By providing a hollowed-out area with an ink layer and a transparent protective layer above the grounding compensation section, the grounding compensation section and the metal component are in direct contact. This area is closer to 0 potential than the surrounding area and can be equivalent to grounding. Thus, the static electricity of the metal component is released through the grounding compensation section. Releasing the static electricity of the metal component through the grounding line can prevent the static electricity from the metal component from affecting the metal trace and the touch area.

[0006] According to another embodiment of the present invention, the grounding compensation part is in direct contact with the metal part in the vertical direction.

[0007] According to another embodiment of the present invention, the distance between the ground wire compensation part and the overlapping area is twice or more the width of the ground wire.

[0008] According to another embodiment of the present invention, the area of ​​the grounding compensation part is 1-3 times the area of ​​the overlapping region.

[0009] According to another embodiment of the present invention, the grounding compensation part is one of a rectangle, rhombus, trapezoid, circle or polygon.

[0010] According to another embodiment of the present invention, the grounding compensation part is metal.

[0011] According to another embodiment of the present invention, the width of the ground wire is 0.1-1 mm.

[0012] According to another embodiment of the present invention, the base includes a body, the body being a conductor, and the metal component communicating with the body.

[0013] According to another embodiment of the present invention, a conductive element is provided on the metal part, and the conductive element is connected to the touch module.

[0014] An electronic device according to a second aspect of the present invention includes any of the touch panels described above.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This invention discloses a touch panel and an electronic device. The touch panel includes a base and a touch module, a display module, and a cover plate disposed on the base. A metal part is disposed on one edge of the base. The touch module includes a touch area and a wiring area. The wiring area is disposed around the touch area and includes multiple metal wirings extending from the touch area. A ground wire is disposed around the metal wirings. An ink layer and a transparent protective layer are disposed sequentially above the metal wirings and the ground wire in the wiring area. The projection patterns of the metal wirings and the metal part in the vertical direction have an overlapping area. A ground wire compensation part is disposed around the overlapping area of ​​the ground wire. A hollow area is disposed above the ground wire compensation part of the ink layer and the transparent protective layer. Therefore, this solution provides a grounding compensation section around the overlapping area of ​​the vertical projection pattern of the metal trace and the metal component. By providing a hollowed-out area with an ink layer and a transparent protective layer above the grounding compensation section, the grounding compensation section and the metal component are in direct contact. This area is closer to 0 potential than the surrounding area and can be equivalent to grounding. Thus, the static electricity of the metal component is released through the grounding compensation section. Releasing the static electricity of the metal component through the grounding line can prevent the static electricity from the metal component from affecting the metal trace and the touch area.

[0034] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0035] To illustrate the touch panel and electronic device provided in this application, the following detailed description is provided in conjunction with the accompanying drawings and textual descriptions of the embodiments.

[0036] The following is for reference. Figures 1-3 A touch panel 100 according to an embodiment of the first aspect of the present invention is described, such as Figures 1-3As shown, the touch panel 100 includes a base 110 and a touch module 120, a display module 130, and a cover plate 140 disposed on the base 110. A metal component 111 is disposed on one edge of the base 110, the metal component 111 serving to connect to an external structure. Specifically, the touch module 120 includes a touch area 121 and a wiring area 122. The wiring area 122 is disposed around the touch area 121 and includes multiple wiring lines from the touch area 121. A metal trace 123 extends from region 121, and a ground wire 124 is provided around the metal trace 123. An ink layer 125 and a transparent protective layer 126 are sequentially disposed above the metal trace 123 and ground wire 124 in trace region 122. The vertical projection of the metal trace 123 and the metal component 111 overlaps in a region 127. A ground wire compensation part 1241 is provided around the overlapping region 127 of the ground wire 124. The ink layer 125 and the transparent protective layer 126... A hollow area 128 is provided above the ground compensation part 1241. The hollow area 128 is used to connect the ground compensation part 1241 and the metal part 111, thereby enabling the ground compensation part 1241 to connect the metal part 111 and the ground wire 124. This allows the static electricity of the metal part 111 to be released through the ground wire 124, preventing the static electricity from the metal part 111 from affecting the metal trace 123 and the touch area 121. It can be seen that by providing the ground compensation part 1241 around the overlapping area 127 of the vertical projection pattern of the metal trace 123 and the metal part 111, and by providing the hollow area 128 above the ink layer 125 and the transparent protective layer 126, the ground compensation part 1241 and the metal part 111 are in direct contact. This area is closer to 0 potential than the surrounding area and can be equivalent to grounding, thereby enabling the static electricity of the metal part 111 to be released through the ground compensation part 1241.

[0037] It should be noted that the area of ​​the hollow area 128 and the area of ​​the ground wire compensation part 1241 can be determined according to the specific application scenario. Preferably, the area of ​​the hollow area 128 and the area of ​​the ground wire compensation part 1241 are the same, so that the ground wire compensation part 1241 and the metal part 111 can be reliably connected.

[0038] It should be noted that the pattern of the ground compensation part 1241 can be determined according to the specific application scenario. For example, the pattern of the ground compensation part 1241 can be a regular pattern with a smooth surface, so as to avoid the discharge of sharp parts and thus affect the metal trace 123 and interfere with the touch effect.

[0039] It should be noted that the touch area 121 may include a first touch layer, a second touch layer and an insulating layer. The insulating layer is disposed between the first touch layer and the second touch layer to achieve electrical isolation between the two. It can be understood that the first touch layer and the second touch layer are respectively led out with metal traces 123, and the metal traces 123 extend from the touch area 121 to the trace area 122 for bonding.

[0040] According to one embodiment of the present invention, such as Figures 1-3 As shown, the grounding compensation part 1241 is in direct contact with the metal part 111 in the vertical direction. It can be understood that by directly connecting the grounding compensation part 1241 with the metal part 111, the metal part 111 and the ground wire 124 are directly connected through the grounding compensation part 1241, thereby forming a complete path for the static electricity discharge of the metal part 111. The static electricity on the metal part 111 is released through the grounding compensation part 1241 and the ground wire 124.

[0041] It should be noted that in some other embodiments, the grounding compensation part 1241 can be connected to the metal part 111 through a conductive intermediate object. Furthermore, the conductive intermediate object can be conductive cloth or conductive pad, etc.

[0042] According to one embodiment of the present invention, such as Figures 1-3 As shown, the distance between the ground wire compensation part 1241 and the overlapping area 127 is twice or more the width of the ground wire 124. It can be understood that in order to avoid the distance between the ground wire 124 and the metal wire being too small, which would damage the metal wire when the ground wire 124 discharges, the distance between the ground wire compensation part 1241 and the overlapping area 127 is twice or more the width of the ground wire 124. Preferably, the distance between the ground wire compensation part 1241 and the overlapping area 127 is twice the width of the ground wire 124.

[0043] According to one embodiment of the present invention, such as Figures 1-3 As shown, the area of ​​the ground compensation part 1241 is 1-3 times the area of ​​the overlapping region 127. It can be understood that the larger the area of ​​the ground compensation part 1241, the larger the proportion of its surface damage area to the total area after multiple discharges. In other words, the probability of reliable connection between the ground compensation part 1241, the ground wire 124, and the metal part 111 after multiple discharges is greater. However, since the ground compensation part 1241 is affected by the overall space, its area cannot be too large. Preferably, the area of ​​the ground compensation part 1241 is twice the area of ​​the overlapping region 127, so as to balance the reliability of discharge and the overall space.

[0044] According to one embodiment of the present invention, such as Figures 1-3As shown, the grounding compensation part 1241 is one of a rectangle, rhombus, trapezoid, circle or polygon. It can be understood that by setting the grounding compensation part 1241 to a conventional shape, it is easy to process and manufacture, and at the same time, it can.

[0045] According to one embodiment of the present invention, such as Figures 1-3 As shown, the grounding compensation part 1241 is made of metal. It can be understood that the grounding compensation part 1241 needs to conduct the metal part 111 and the ground wire 124. Therefore, the grounding compensation part 1241 needs to have the function of conducting electricity. Preferably, the grounding compensation part 1241 is made of metal, which can improve the conductivity and has the advantages of high strength and low cost. Furthermore, the grounding compensation part 1241 can be made of copper.

[0046] According to one embodiment of the present invention, such as Figures 1-3 As shown, the width of the ground wire 124 is 0.1-1mm. Preferably, the width of the ground wire 124 can be 0.2mm, or 0.5mm, or 0.8mm.

[0047] It should be noted that the ground wire 124 is located around the metal conductor, which has the effect of shielding the touch area 121 from interference, and at the same time, it can achieve the effect of static discharge.

[0048] According to one embodiment of the present invention, such as Figures 1-3 As shown, the base 110 includes a main body 112, which is a conductor. The metal part 111 is connected to the main body 112. It can be understood that the base 110 is used to protect the touch module 120 and the display module 130. Therefore, the main body 112 can be a conductor to achieve electrostatic discharge. By connecting the metal part 111 and the main body 112, the electrostatic discharge effect of the metal part 111 is further enhanced.

[0049] According to one embodiment of the present invention, such as Figures 1-3 As shown, a conductive element (not shown in the figure) is provided on the metal part 111. The conductive element is connected to the touch module 120. It can be understood that the metal part 111 and the touch module 120 are connected, which further enhances the electrostatic discharge effect of the metal part 111. Specifically, the conductive element is a conductive cloth or a conductive pad.

[0050] The following is for reference. Figure 4 An electronic device 10 according to an embodiment of a second aspect of the present invention is described, such as... Figure 4As shown, the electronic device 10 includes a touch panel 100, which includes a base 110 and a touch module 120, a display module 130, and a cover plate 140 disposed on the base 110. A metal component 111 is disposed on one edge of the base 110, the metal component 111 serving to connect to an external structure. Specifically, the touch module 120 includes a touch area 121 and a wiring area 122, the wiring area 122 being disposed around the touch area 121. Domain 122 includes multiple metal traces 123 extending from the touch area 121. A ground line 124 is disposed around the metal traces 123. An ink layer 125 and a transparent protective layer 126 are sequentially disposed above the metal traces 123 and ground line 124 in the trace area 122. The vertical projection patterns of the metal traces 123 and the metal component 111 overlap in a region 127. A ground line compensation portion 1241 is disposed around the overlap region 127 of the ground line 124. The ink layer 125... A cutout area 128 is provided above the grounding compensation section 1241 and the transparent protective layer 126. The cutout area 128 is used to connect the grounding compensation section 1241 and the metal part 111, thereby enabling the grounding compensation section 1241 to connect the metal part 111 and the ground wire 124. This allows the ground wire 124 to release static electricity from the metal part 111, preventing static electricity from the metal part 111 from affecting the metal trace 123 and the touch area 121. Therefore, by using the metal... A grounding compensation section 1241 is provided around the overlapping area 127 of the vertical projection pattern of the trace 123 and the metal part 111. At the same time, by providing a hollow area 128 with an ink layer 125 and a transparent protective layer 126 above the grounding compensation section 1241, the grounding compensation section 1241 and the metal part 111 are in direct contact. This area is closer to 0 potential than the surrounding area and can be equivalent to grounding, thereby realizing the static discharge of the metal part 111 through the grounding compensation section 1241.
