For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments of the present application.

Furthermore, the terms "first," "second," "third," and the like are used merely to distinguish between descriptions and should not be construed as indicating or implying relative importance.
It should be noted that, in the case of no conflict, different features in the embodiments of the present application may be combined with each other.
Referring to fig. 1 and fig. 2, in some touch panels, an effective display area 10 is provided with staggered first touch electrodes 110 and second touch electrodes 120, each of the first touch electrodes 110 or the second touch electrodes 120 is composed of a plurality of electrode blocks, and the electrode blocks are connected with each other through a bridging structure 130. The bridging structures 130 of the first touch electrode 110 and the second touch electrode 120 are located in different film layers and are isolated from each other by an insulating layer, and there is an overlapping region in space. For example, the electrode block of the first touch electrode 110, the electrode block of the second touch electrode 120, and the bridge structure 130 of the first touch electrode 110 may be located in the same metal layer, while the bridge structure 130 of the second touch electrode 120 may be located in another metal layer, where the two metal layers are isolated from each other by an insulating layer, and the bridge structure 130 of the second touch electrode 120 is connected to the electrode block of the second touch electrode 120 by a through hole penetrating through the insulating layer. The bridging structure 130 of the first touch electrode 110 and the bridging structure 130 of the second touch electrode 120 have overlapping portions, that is, orthographic projections of the bridging structure 130 of the first touch electrode 110 and the bridging structure 130 of the second touch electrode 120 on the insulating layer have overlapping areas.
When static electricity generated in the manufacturing process of the touch panel is transferred into the effective display area through different touch electrodes, a voltage difference may be generated between the first touch electrode 110 and the second touch electrode 120, and the bridging structure 130 at the overlapping position of the first touch electrode 110 and the second touch electrode 120 has a relatively narrow effective line width, and is easily broken by static electricity injury, thereby causing poor touch function.
In order to improve the electrostatic protection effect, in some display panels, a grounded anti-electrostatic surrounding wiring 600 is disposed around the effective display area 10 for absorbing static electricity. However, on the touch panel side, the touch trace 210 needs to be led out to the bonding area 20 to connect with the touch driving chip, where the anti-static surrounding trace 600 cannot be disposed. Therefore, static electricity is easily introduced into the effective display area 10 through the touch trace 210, and the bridging structure 130 of the touch electrode is damaged.
In view of this, the present embodiment provides a solution for improving the electrostatic protection capability in the manufacturing process of the display panel, and the solution provided in the present embodiment is described in detail below.
The touch panel provided in this embodiment includes at least one first touch electrode 110 extending along a first direction and at least one second touch electrode 120 extending along a second direction, where the first direction intersects with the second direction. The first touch electrode 110 and the second touch electrode 120 may be located in an effective display area of the touch panel. The first touch electrode 110 and the second touch electrode 120 may be respectively composed of a plurality of electrode blocks, and adjacent electrode blocks are connected by a bridging structure.
Referring to fig. 3, the touch panel provided in the present embodiment may further include at least two touch traces 210, where the at least two touch traces 210 include a first touch trace 211 and a second touch trace 212.
The first touch trace 211 is electrically connected to the first touch electrode 110, and the second touch trace 212 is electrically connected to the second touch electrode 120. Each of the touch traces 210 may guide the first touch electrode 110 and the second touch electrode 120 from different directions to one side of the touch panel, so as to be connected to the touch driving chip.
For example, referring to fig. 4, the touch panel includes an effective display area 10 and a bonding area 20 located at one side of the effective display area 10 in the first direction, and the bonding area may be folded to the back of the effective display area 10. One end of the first touch trace 211 is connected to the first touch electrode 110, and the other end extends to the bonding region 20 along the first direction; one end of the second touch trace 212 is connected to the second touch electrode, and the other end extends from two sides of the effective display area or one side of the effective display area to the bonding area 20 along the first direction.
The touch panel further includes at least one first switching device 310, and in a closed state of the first switching device 310, the first touch trace 211 is shorted with the second touch trace 212. For example, when the first switching device 310 is closed, the first touch trace 211 and the second touch trace 212 may be shorted to each other or both may be shorted to the same shorting trace.
In this way, in some manufacturing steps of the touch panel, the first switching device 310 may be controlled to be closed so as to short the first touch trace 211 and the second touch trace 212, so that each of the first touch trace 211 and the second touch trace 212 may be at the same level. In this way, when static electricity is conducted to the effective display area, the bridge structure 130 is prevented from being damaged due to the overlarge voltage difference between the bridge structures 130 of the first touch electrode 110 and the second touch electrode 120, thereby improving the yield of the touch panel.
And when the touch panel works normally, the first switching device 310 may be controlled to be turned off, so as to release the short circuit between the first touch trace 211 and the second touch trace 212, so that each of the first touch trace 211 and the second touch trace 212 may independently transmit or receive a touch signal.
In one possible implementation manner, the touch panel includes a plurality of the first touch electrodes 110, a plurality of the second touch electrodes 210, a plurality of the first touch traces 211, and a plurality of the second touch traces 212, where the first touch traces 211 are correspondingly electrically connected to the first touch electrodes 110, and the second touch traces 212 are correspondingly electrically connected to the second touch electrodes. For example, the first touch traces 211 are respectively and electrically connected to the first touch electrodes 110 in a one-to-one correspondence, and the second touch traces 212 are respectively and electrically connected to the second touch electrodes 120 in a one-to-one correspondence.
The touch panel further includes a plurality of first switching devices 310, where the plurality of touch traces 210 are all shorted when the plurality of first switching devices 310 are in a closed state. For example, when the plurality of first switching devices 310 are closed, the plurality of first touch traces 211 and the plurality of second touch traces 212 may be shorted to each other or all be shorted to the same shorting trace.
For example, the control end of each first switching device 310 may be connected to a touch driving chip or other processing chip of the touch panel through a signal control line to obtain a control signal, so as to control shorting each first switching device 310 according to the control signal.
Thus, in some manufacturing steps of the touch panel, the plurality of first switching devices 310 may be controlled to be closed to short each touch trace 210, so that each touch trace 210 may be at the same level. In this way, the bridge structure 130 is prevented from being damaged due to the excessive voltage difference between the bridge structures 130 of the touch electrodes in different directions when static electricity is conducted to the effective display area, thereby improving the yield of the touch panel.
When the touch panel works normally, the plurality of first switching devices 310 may be controlled to be turned off, so as to release the mutual shorting of the touch traces 210, and the touch traces 210 may independently transmit or receive touch signals.
In one possible implementation, the first switching device 310 may include an input terminal, an output terminal, and a control terminal. Referring to fig. 5, one of the input end and the output end of each of the first switching devices 310 is connected to the first touch trace 211, and one of the input end and the output end of each of the first switching devices 310 is connected to the second touch trace 212.
In one example, the control terminals of the first switching devices 310 may receive the same on control signal at the same time, for example, the control terminals of the first switching devices 310 may be connected to the same signal control line 410. In another example, the control terminal of each of the first switching devices 310 may be respectively connected to different signal control lines 410, but different signal control lines 410 may simultaneously transmit the same on control signal.
Preferably, in this embodiment, the first touch trace 211 and the second touch trace 212 extend to the bonding region along the first direction, and are arranged along the second direction in the bonding region. The first switching device may be connected between every two adjacent touch traces 210. The first switching device 310 is closed when the control terminal thereof obtains a closing control signal, so that the input terminal and the output terminal thereof are conducted, and the touch trace 210 connected with the input terminal and the output terminal is short-circuited. The plurality of first switching devices 310 are controlled by the same signal control line 410 to be simultaneously closed, so that the plurality of touch traces 210 are shorted to each other.
Further, based on the scheme shown in fig. 5, in an example, the touch panel may further include a second switching device 320, one of an input end and an output end of the second switching device 320 is connected to the touch trace 210, and the other of the input end and the output end of the second switching device 320 is connected to the ground line 500. Preferably, the control terminal of the second switching device 320 is also connected to the signal control line 410. In this way, each of the touch traces 210 is grounded while being shorted, so that static electricity generated on the first touch electrode 110 and the second touch electrode 120 can be released.
In another example, referring to fig. 7, the touch panel further includes an anti-static surrounding trace 600 surrounding the effective display area 10 of the touch panel. Referring to fig. 8, the touch panel further includes a third switching device 330, one of an input end and an output end of the third switching device 330 is connected to the touch trace 210, and the other of the input end and the output end of the third switching device 330 is connected to the anti-static surrounding trace 600. Preferably, a control terminal of the third switching device 330 is connected to the signal control line 410. In this way, each of the touch traces 210 is shorted with the anti-static surrounding trace 600 while being shorted, so that the first touch electrode 110 and the second touch electrode 120 are equipotential with the anti-static surrounding trace 600, and electrostatic discharge is better avoided. In some examples, the anti-static wrap around trace 600 may also be grounded.
Further, in one example, two third switching devices 330 are provided, wherein an input end or an output end of one third switching device 330 is electrically connected to one end of the anti-static encircling trace 600, and an input end or an output end of the other third switching device 330 is electrically connected to the other end of the anti-static encircling trace 600. For example, after the anti-static surrounding wire 600 surrounds the effective display area 10, both ends of the anti-static surrounding wire 600 extend to the bonding area 20, and the two third switching devices 330 are respectively connected to both ends of the anti-static surrounding wire 600.
In another possible implementation, referring to fig. 9, the touch panel further includes a shorting trace 420, where one of an input end and an output end of each of the first switching devices 310 is connected to the shorting trace 420, and the other of the input end and the output end of each of the first switching devices 310 is connected to the touch trace 210. In this manner, each of the first switching devices 310 is closed such that each of the touch traces 210 connected thereto may be shorted to the shorting trace 420, thereby shorting the touch traces 210 to each other through the shorting trace 420.
In one example, the control terminals of the first switching devices 310 may receive the same on control signal at the same time, for example, the control terminals of the first switching devices 310 may be connected to the same signal control line 410. In another example, the control terminal of each of the first switching devices 310 may be respectively connected to different signal control lines 410, but different signal control lines 410 may simultaneously transmit the same on control signal.
Optionally, the grounding trace may be located at a different layer of the bonding region extending along the second direction from the first touch trace 211 and the second touch trace 212.
Further, based on the scheme shown in fig. 9, in one example, the shorting trace 420 is connected to the ground line 500. In this way, each of the touch traces 210 is grounded while being shorted, so that static electricity generated on the first touch electrode 110 and/or the second touch electrode 120 can be released.
In one possible implementation, referring to fig. 11, a plurality of touch traces 210 extend to the bonding area 20, and a plurality of first switching devices 310 are located in the bonding area 20. In this way, the first switching device 310 can be prevented from occupying the effective display area 10, and the screen ratio of the touch panel can be improved.
Further, in one possible implementation, referring to fig. 11, the touch panel further includes a touch driving chip 610 disposed on the bonding area 20, and the control end of each of the first switching devices 310 is electrically connected to the touch driving chip 610.
In one possible implementation, the first switching device 310 includes an N-type transistor or a P-type transistor. For example, the first switching device 310 may be a thin film transistor (Thin Film Transistor, TFT) formed in an array substrate of the touch panel.
In one possible implementation, the touch panel may include an array substrate, a light emitting layer located on one side of the array substrate, and a touch layer located on a side of the light emitting layer away from the array substrate, the first touch electrode 110 and the second touch electrode 120 are located in the touch layer, and the first switching device 110 is located in the array substrate.
Wherein, in one example, the touch layer may be formed based on the light emitting layer, for example, the touch layer is formed on a cover layer or a thin film encapsulation layer on the light emitting layer; alternatively, the touch layer may be formed separately and then attached to the light emitting layer.
The embodiment of the application also provides electronic equipment, which comprises the touch panel provided by the embodiment of the application.
In summary, in the touch panel and the electronic device provided by the embodiments of the present application, the plurality of first switching devices are added in the touch panel, so that the plurality of first switching devices can short the first touch trace and the second touch trace when being closed, and the first touch electrode and the second touch electrode can be at the same level. Therefore, static electricity can be prevented from being conducted to an effective display area, and the bridging structures of the touch electrodes in different directions are prevented from being damaged due to overlarge voltage difference, so that the yield of the touch panel is improved.
