Abstract
Description
Technical Field
[0001] This application relates to the field of display technology, and more specifically, to an anti-static touch cover and display device. Background Technology
[0002] In the development of touch cover plates, sensor electrode pattern layers have been widely used in the functional lines of various sensors due to their excellent transparent conductivity. However, conventional grounding wires use a closed-loop design, i.e., a complete grounding wire structure. When static electricity enters, the entire grounding ring is prone to electrostatic discharge. The static electricity flowing inward can damage the inner horizontal and vertical electrodes. Since the horizontal and vertical electrodes are inherently sensitive, they are easily burned out once affected by static electricity, leading to open circuits or partial failures in the circuitry, seriously affecting the normal operation and lifespan of the touch cover plate. This phenomenon is particularly common during use, as static electricity easily accumulates and dissipates, posing a threat to the sensitive ITO lines (i.e., electrodes). Utility Model Content
[0003] The technical problem to be solved by the embodiments of this application is to reduce or even avoid the influence of static electricity on the sensor electrode pattern layer and functional wiring, so as to improve the stability and reliability of the sensor and adapt to a wider range of application scenarios.
[0004] To solve the above-mentioned technical problems, the following technical solution was adopted:
[0005] An antistatic touch cover, comprising:
[0006] A substrate, a sensor electrode pattern layer and functional traces disposed on the substrate, wherein the functional traces are connected to each electrode of the sensor electrode pattern layer and extend to one side of the substrate to form an FPC bonding area;
[0007] A grounding wire is also provided around the functional wiring. When viewed from above, the grounding wire has a U-shaped structure, with its two ends located on both sides of the FPC bonding area. A break point is also provided at any point on the grounding wire to divide the grounding wire into a first grounding wire and a second grounding wire.
[0008] Furthermore, the end of the first or second grounding wire at the break point continues to extend to form an extension line, which covers the break point.
[0009] Furthermore, a discharge tip group is added around the grounding wire to allow static electricity to be released towards the discharge tip.
[0010] Furthermore, the discharge tip group is preferably located at the corner of the grounding wire.
[0011] Furthermore, the discharge tip group includes a plurality of first discharge tips disposed at the corner of the grounding wire, and a plurality of second discharge tips are disposed at intervals opposite to the plurality of first discharge tips.
[0012] Furthermore, both the first discharge tip and the second discharge tip are wedge-shaped.
[0013] Furthermore, the sensor electrode pattern layer includes several intersecting horizontal and vertical electrodes disposed on the substrate.
[0014] A display device includes an anti-static touch cover and a display panel as described above, wherein the display panel and the touch cover are fully bonded together.
[0015] Compared with the prior art, the embodiments of this application have the following main advantages:
[0016] This utility model discloses an anti-static touch cover plate, which is provided with a grounding wire around the functional wiring. In a top view, the grounding wire has a U-shaped structure, with its two ends located on both sides of the FPC bonding area. There is also a break point at any point on the grounding wire to divide the grounding wire into a first grounding wire and a second grounding wire, so that it cannot form an electrostatic loop and reduce damage to one side of the sensor electrode pattern layer.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.
[0027] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0028] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.
[0029] Anti-static touch cover
[0030] like Figure 1-5 As shown, the anti-static touch cover of this application includes a substrate 100, a sensor electrode pattern layer 200, a functional trace 300, a connecting wire 400, and an FPC bonding area 500.
[0031] Both the sensor electrode pattern layer 200 and the functional traces 300 are disposed on the substrate 100. The sensor electrode pattern layer 200 includes a plurality of intersecting horizontal electrodes 210 and vertical electrodes 220 disposed on the substrate 100 (e.g., ...). Figure 3 As shown), several functional traces 300 are connected to and led out from each horizontal electrode and vertical electrode to one side of the substrate to form an FPC bonding area 500. The FPC bonding area 500 is used to bond the FPC 600 (e.g., Figure 2 As shown), the sensor electrode pattern layer 200 is electrically connected to the FPC 600 through the functional trace 300;
[0032] like Figure 6 As shown, a grounding wire 400 is provided on the outermost periphery of the functional trace 300. In a top view, the grounding wire 400 has a U-shaped structure. The two ends of the grounding wire 400 are located on both sides of the FPC bonding area 500, that is, one end of the grounding wire 400 is located on one side of the FPC bonding area 500, and the other end extends around the three sides of the sensor electrode pattern layer 200 to the other side of the FPC bonding area 500. Furthermore, a break point 410 is provided at any point on the grounding wire 400, that is, the original whole grounding wire 400 is interrupted by the break point 410 to form a first grounding wire 420 and a second grounding wire 430, so that it cannot form an electrostatic ring and reduce damage to one side of the sensor electrode pattern layer 200.
[0033] Furthermore, the end of the first grounding wire 420 or the second grounding wire 430 at the break point 410 continues to extend to form an extension line 440. The extension line 440 blocks the break point 410 to prevent static electricity from easily entering directly through the gap at the break point 410.
[0034] Furthermore, such as Figure 5 , 6 As shown, a discharge tip group is also provided around the grounding wire 400 to release static electricity towards the static tip and avoid releasing it towards the internal sensor electrode pattern layer 200.
[0035] Furthermore, the discharge tip group is preferably located at the corner of the grounding wire 400, such as the corner of the grounding wire 420 and the grounding wire 430. With this design, the addition of the discharge tip group does not require an additional increase in the size of the substrate.
[0036] Specifically, the discharge tip group includes several first discharge tips 700 disposed at the corner of the connecting wire 400, and several second discharge tips 800 disposed at intervals opposite to the several first discharge tips 700.
[0037] Based on the above structural analysis, the first and second discharge tips are designed to release accumulated static electricity. The first discharge tip 700 is located at the edge of the grounding wire 400 and faces the second discharge tip 800, forming a static electricity release channel, which effectively prevents static electricity from affecting signal transmission.
[0038] Furthermore, both the first discharge tip 700 and the second discharge tip 800 are wedge-shaped, such as... Figure 5 As shown.
[0039] Based on the above structural analysis, the wedge shape provides guidance for electrostatic discharge and is beneficial for conducting static electricity.
[0040] Display devices
[0041] The display device includes an anti-static touch cover and a display panel, as described above, with the display panel and touch cover fully bonded together.
