Before explaining the technical solutions provided by the embodiments of the present application, in order to facilitate understanding of the embodiments of the present application, the present application first specifically explains the problems existing in the related art:

the touch panel may adopt a design of 2TX +1RX or 2TX +2RX, where TX is a driving channel and RX is a sensing channel. For example, for 2TX +1RX, two ends of the driving channel TX are respectively connected to a lead wire, and in the related art, the two lead wires are respectively connected to different binding terminals, so that the number of the binding terminals required for the driving channel TX is increased by multiple times, which results in an increase in the width of a binding region, and if an FPC (Flexible Printed Circuit) is used for binding with the binding region, the cost of the FPC is increased.

In order to solve the above technical problems, embodiments of the present application provide a touch panel and an electronic device, and the following describes embodiments of the touch panel and the electronic device with reference to the accompanying drawings.

First, a touch panel provided in an embodiment of the present application will be described.

Fig. 1 is a schematic top view of a touch panel according to an embodiment of the present disclosure, and fig. 2 is a partially enlarged view of an example of a Q region in fig. 1. As shown in fig. 1 and fig. 2, a touch panel 100 provided in the embodiment of the present application may include a touch channel 10, where the touch channel 10 includes a first channel 11 and a second channel 12, the first channel 11 extends along a first direction X, the second channel 12 extends along a second direction Y, and the first direction X and the second direction Y intersect with each other. Illustratively, the first direction X and the second direction Y may be perpendicular to each other. The first direction X may be a row direction, and the second direction Y may be a column direction. Of course, the row and column directions may be interchanged. One of the first channel 11 and the second channel 12 is a driving channel, and the other is a sensing channel. For example, the first channel 11 may be a sensing channel and the second channel 12 may be a driving channel. Alternatively, the first channel 11 may be a drive channel and the second channel 12 may be a sense channel.

Where the first channel 11 and the second channel 12 cross, a mutual capacitance may be formed. The working process of the touch panel may be that an excitation signal is applied to the driving channel, the sensing channel may sense and receive the excitation signal due to the existence of the mutual capacitance, and the magnitude and the phase shift of the signal received by the sensing channel are related to the frequency of the applied excitation signal and the magnitude of the mutual capacitance. The frequency of the applied stimulation signal is known, that is, the touch location is determined by the mutual capacitance between the drive and sense channels. When a finger approaches or touches the touch panel, the finger acts as a conductor, so that the part of the electric field or the electric line of force originally from the driving channel to the sensing channel is transferred to the finger, and the reduction of the field strength or the reduction of the electric line of force between the two channels is equivalent to the reduction of the mutual capacitance. Therefore, the position where the mutual capacitance is reduced can be determined as the touch position of the finger.

The end of the touch channel 10 is connected with a lead 20, and the lead 20 is connected with a corresponding binding terminal 30. Both ends of at least one of the first and second channels 11 and 12 may be each connected with a lead 20. That is, the touch panel may adopt a design of 2TX +1RX or 2TX +2RX, so as to reduce the voltage drop of the leads. For the touch channel 10 with the leads 20 connected to both ends, the leads 20 at both ends of the touch channel 10 may be connected to the same binding terminal 30.

Fig. 1 and 2 take a design of a touch panel adopting 2TX +1RX as an example, a first channel 11 is a sensing channel, a second channel 12 is a driving channel, for convenience of understanding, a lead connected to the first channel 11 is referred to as a first channel lead 21, a lead connected to two ends of the second channel 12 is referred to as a second channel lead 22, a binding terminal connected to the first channel lead 21 is referred to as a first binding terminal 31, and a binding terminal connected to the second channel lead 22 is referred to as a second binding terminal 32. As shown in fig. 1 or 2, two second channel leads 22 connected to both ends of the second channel 12 may be respectively connected to the same second binding terminal 32, one end of the first channel 11 is connected to the first channel lead 21, and the first channel lead 21 is connected to the first binding terminal 31. For example, two second channel leads 22 connected to both ends of the second channel 12 may be respectively connected to the same second binding terminal 32, and it is understood that the two second channel leads 22 may be respectively connected to different positions of the same second binding terminal 32.

The drawings of the present application are only examples and are not intended to limit the present application, for example, in the design of 2TX +1RX, two leads connected to two ends of the first channel 11 may be connected to the same binding terminal, and one end of the second channel 12 is connected to a lead. For another example, in the design of 2TX +2RX, two leads connected to both ends of the first channel 11 may be connected to the same bonding terminal, and two leads connected to both ends of the second channel 12 may be respectively connected to the same bonding terminal.

For example, the touch panel may include a touch region S1 and a bezel region S2 surrounding the touch region S1. The frame region S2 may include a binding region S21. The touch channel 10 can be disposed in the touch region S1, the bonding terminals 30 can be disposed in the bonding region S21, and the leads 20 can be routed in the frame region S2.

For example, still taking the design of the touch panel in fig. 1 and 2 adopting 2TX +1RX as an example, the first channel 11 is a sensing channel, the second channel 12 is a driving channel, each first channel 11 is connected to one first channel lead 21, two ends of each second channel 12 are respectively connected to second channel leads 22, and the second channel leads 22 at two ends of each second channel 12 are respectively connected to the same second binding terminal 32, for example, 34 first channels 11 and 16 second channels 12 are provided, in this embodiment, the number of binding terminals required for the touch channel 10 is 34+ 16-50. If the second channel leads 22 at the two ends of each second channel 12 are respectively connected to different second bonding terminals 32, the number of bonding terminals required for the touch channel 10 is 34+2 × 16 — 66.

According to the touch panel provided by the embodiment of the application, the plurality of lead wires connected with the two ends of the same touch channel are respectively connected to the same binding terminal, so that on one hand, the number of the binding terminals required by the touch channel can be reduced, the size of a binding area in a first direction is prevented from being increased, and if an FPC (flexible printed circuit) is used for binding with the binding area, the cost of the FPC can be prevented from being increased; on the other hand, for in the correlation technique will connect many lead wires at same touch-control passageway both ends and merge, rethread one section common line connection after merging binds the terminal, different lines will have alternately like this, and walk the line intersection and need set up the line in different retes and utilize via hole connection, will reduce the reliability, and many lead wires are connected to same binding terminal respectively in this application embodiment, connect just also need not merge many lead wires respectively, just so can avoid different lead wires to have alternately, improve the reliability, and do not intersect between the different lead wires, can avoid alternately the signal interference who leads to.

In some optional embodiments, still taking the first channel 11 as the sensing channel, the second channel 12 as the driving channel, and the two second channel leads 22 connected to two ends of the same second channel 12 are respectively connected to the same second binding terminal 32 as an example, please refer to fig. 1 or fig. 2, the plurality of binding terminals 30 may be located on one side of the touch channel 10 in the second direction Y, for example, the plurality of binding terminals 30 may be located on the upper side of the touch channel 10, and the plurality of binding terminals 30 may be arranged along the first direction X. The binding terminal 30 may have a certain length in the second direction Y and a certain width in the first direction X. Each binding terminal 30 may include a first end a and a second end b in the second direction Y, and the two second channel leads 22 connecting both ends of the same second channel 12 are connected to the first end a and the second end b of the second binding terminal 32, respectively.

Since the two second channel leads 22 are connected to the first end a and the second end b of the second binding terminal 32, the second channel leads 22 do not need to run between the adjacent binding terminals 30, and the distance between the adjacent binding terminals 30 in the first direction X can be set to be relatively small, so that the size of the binding region S21 in the first direction X is further reduced, and the FPC cost is further reduced.

For example, if there is no requirement for the pitch of the adjacent binding terminals 30 in the first direction X, two second channel leads 22 may also be connected to positions between the first and second ends a and b of the second binding terminals 32, respectively.

In some optional embodiments, with continued reference to fig. 1 or fig. 2, the first end a of the second bonding terminal 32 is an end of the second bonding terminal 32 close to the touch channel 10, the second end b of the second bonding terminal 32 is an end of the second bonding terminal 32 far from the touch channel 10, the two second channel leads 22 connecting two ends of the same second channel 12 include a first lead 221 and a second lead 222, the first lead 221 is connected to the end of the second channel 12 close to the bonding terminal 30, the second lead 222 is connected to the end of the second channel 12 far from the bonding terminal 30, the first lead 221 can be connected to the first end a of the second bonding terminal 32, and the second lead 222 can be connected to the second end b of the second bonding terminal 32.

The first lead 221 is connected to the first end a of the second binding terminal 32, the end of the second channel 12 connected to the second lead 222 is relatively far from the second binding terminal 32, and the second lead 222 is connected to the second end b of the second binding terminal 32, so that the second lead 222 can be disposed on the periphery of the first lead 221, and crossing between the leads is avoided, thereby avoiding signal interference and improving signal stability of each lead.

In some alternative embodiments, there may be no crossing between the first and second leads 221 and 222 as described above, and the first and second leads 221 and 222 may be located in the same film layer. Thus, the first lead 221 and the second lead 222 can be simultaneously prepared in the same process step, and the process complexity is reduced.

For example, the lead wires 20 connected to each touch channel 10 may be located on the same film layer. For example, the first channel lead 21 connected to the first channel 11 and the first lead 221 and the second lead 222 connected to the second channel 12 are both located in the same film layer, so that all the leads can be simultaneously prepared in the same process step, and the process complexity is further reduced.

In some alternative embodiments, the plurality of second lead lines 222 corresponding to the plurality of second channels 12 may extend to the same side of the touch channel 10 in the first direction X, and the plurality of first channel lead lines 21 corresponding to the plurality of first channels 11 may extend to the other side of the touch channel 10 in the first direction X. For example, as shown in fig. 1, the plurality of second lead lines 222 may extend to the second binding terminals 32 at the right side of the touch channel 10, and the plurality of first channel lead lines 21 may extend to the first binding terminals 31 at the left side of the touch channel 10. In the process of determining the touch position, the signals on the second lead line 222 and the first channel lead line 21 are different, and the signals are extended to both sides of the touch channel 10, so that signal interference can be further avoided.

In some alternative embodiments, as shown in fig. 1 or fig. 2, a plurality of binding terminals 30 are distributed in a row in the first direction X; still taking the binding terminals correspondingly connected to the first channel 11 as the first binding terminals 31 and the binding terminals correspondingly connected to the second channel 12 as the second binding terminals 32 as an example, the plurality of first binding terminals 31 may be located at one side of a row and the plurality of second binding terminals 32 may be located at the other side of the row. For example, the plurality of first binding terminals 31 are located on the left side of a row of binding terminals, the plurality of first channel leads 21 extend on the left side of the touch channel 10, the plurality of second binding terminals 32 are located on the right side of a row of binding terminals, and the plurality of second leads 222 are located on the right side of the touch channel 10, so that the leads and the corresponding binding terminals connected thereto are on the same side of the touch panel, the distance between the leads and the corresponding binding terminals connected thereto can be reduced, and the voltage drop of the leads can be reduced.

Fig. 3 is a schematic cross-sectional view taken along line a-a of fig. 2. In some alternative embodiments, as shown in fig. 3, the touch panel 100 may include a substrate 01, a first conductive layer 02, and a second conductive layer 03. The base substrate 01 may be a glass substrate. The first conductive layer 02 is located on one side of the substrate base plate 03, and the second conductive layer 03 is located on one side of the first conductive layer 02 far away from the substrate base plate 01 and is insulated from the first conductive layer 02. For example, an insulating layer 04 may be disposed between the first conductive layer 02 and the second conductive layer 03. The insulating layer 04 may include SiOx. The first conductive layer 02 may include Mo, and the second conductive layer 03 may include ITO.

The first and second wires 221 and 222 may be disposed on the first conductive layer 02. Illustratively, the first channel lead 21 may also be disposed on the first conductive layer 02.

As such, the second binding terminal 32 may include a plurality of film layers, which may reduce the resistance of the second binding terminal 32.

Illustratively, the first binding terminal 31 may also include a first portion disposed on the first conductive layer 02 and a second portion disposed on the second conductive layer 03, thereby reducing the resistance of the first binding terminal 31.

For example, the number of the via holes may include two, and the two via holes may be respectively located at both ends of the second binding terminal 32 in the second direction Y. Thus, the first branch 321 and the second branch 322 of the second binding terminal 32 correspond to a parallel structure, and the resistance of the second binding terminal 32 can be further reduced.

Illustratively, the structure of the first binding terminal 31 may be identical to that of the second binding terminal 32.

As shown in fig. 4, the first electrode block 111 and the second electrode block 121 may be disposed on the second conductive layer 03. The second connection line 122 crosses the first connection line 112, for example, the first connection line 112 may be disposed on the second conductive layer 03, and the second connection line 122 may be disposed on the first conductive layer 02 and connected to the second electrode block 121 through a via hole. The touch panel may further include a protective layer 05, and the protective layer 05 covers the second conductive layer 03. As shown in fig. 3, the protective layer 05 exposes each binding terminal 30.

In some alternative embodiments, as shown in fig. 1 or fig. 2, a first shield terminal 33 is provided between the first binding terminal 31 and the second binding terminal 32. The first shielding terminal 33 may be used to receive a fixed signal, for example, the first shielding terminal 33 may be used to receive a ground signal, thereby shielding signal interference between the first binding terminal 31 and the second binding terminal 32. The first shielding terminal 33 may be connected with a first shielding line 331, and the first shielding line 331 and the leads 21, 221, and 222 may be located in the same film layer.

Illustratively, the row of binding terminals 30 is provided with a second shielding terminal 34 on at least one side in the first direction X, the second shielding terminal 34 can also be used for receiving a fixed signal, for example, the second shielding terminal 34 can be used for receiving a ground signal, and the second shielding wire 341 connected with the second shielding terminal 34 at least partially surrounds the lead 20. Thus, the second shielding wire 341 can shield the interference of other signals to the lead 20, and can also discharge static electricity to the lead 20.

For example, the second shielding line 341 and the leads 21, 221, and 222 may be located in the same film layer.
