In the description of the present application, it should be noted that, unless explicitly specified and limited otherwise, the terms "mounted," "connected," and "attached" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the terms in this application will be understood by those of ordinary skill in the art as the case may be.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present application without departing from the spirit or scope of the application. Accordingly, this application is intended to cover such modifications and variations of this application as fall within the scope of the appended claims (the claims) and their equivalents. The embodiments provided in the examples of the present application may be combined with each other without contradiction.

Before describing the technical solution 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 describes the problems existing in the related art:

as described in the background art, at least a part of the area where the touch lead is located in the related art has a problem of poor visual effect.

The inventor conducts analysis research on the reason of the problem, and discovers that the ink can be used in the touch product, but poor visual effect of white edges can occur in a certain space close to the touch area due to the influence of the ink coverage precision and the reflective characteristic of the touch lead.

In order to solve the above technical problems, embodiments of the present application provide a touch panel, a touch display panel, and a display device, and embodiments of the touch panel, the touch display panel, and the display device will be described below with reference to the accompanying drawings.

The touch panel provided in the embodiments of the present application will be first described below.

Fig. 1 illustrates a schematic diagram of a touch panel according to an embodiment of the present application. As shown in fig. 1, the touch panel 100 includes a touch area 10 and a trace area 20, the trace area 20 includes a first trace area 21 and a second trace area 22, and the first trace area 21 is located between the touch area 10 and the second trace area 22 in a first direction X. It can be appreciated that, in the first direction X, the first routing area 21 is disposed close to the touch area 10, and the second routing area 22 is disposed far from the touch area 10. The routing area 20 may also be referred to as a bezel area. The interface of the first trace region 21 and the second trace region 22 may be an ink boundary. The ink covers the touch area 10 and the first routing area 21, and the interface of the first routing area 21 and the second routing area 22 can be understood as the furthest boundary of the ink.

Fig. 2 is a schematic top view of a touch panel according to an embodiment of the present application. As shown in fig. 2, the touch area 10 may include a plurality of first touch channels 11 and a plurality of second touch channels 12. The plurality of first touch channels 11 may all extend along the second direction Y and be arranged in the first direction X. The plurality of second touch channels 12 may extend along the first direction X and be arranged in the second direction Y.

One of the first touch channel 11 and the second touch channel 12 may be a driving channel, and the other may be a sensing channel. For example, the first touch channel 11 may be a sensing channel, and the second touch channel 12 may be a driving channel. Alternatively, the first touch channel 11 may be a driving channel, and the second touch channel 12 may be a sensing channel.

The mutual capacitance may be formed where the first touch channel 11 and the second touch channel 12 cross. The touch panel may be operated by applying an excitation signal to the driving channel, and the sensing channel may sense and receive the excitation signal due to the mutual capacitance, where the magnitude and 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 excitation signal is known, that is, the touch position is determined by the mutual capacitance between the drive channel and the sense channel. When a finger approaches or touches the touch panel, the finger corresponds to one conductor, so that part of the electric field or the electric line of force originally going from the driving channel to the sensing channel is transferred to the finger, and the weakening of the field strength or the reduction of the electric line of force between the two channels corresponds to the reduction of the mutual capacitance. Therefore, the position where the mutual capacitance is reduced can be determined to be the touch position of the finger.

It should be noted that, the structure of the touch panel provided in the present application may include, but is not limited to, the structure shown in fig. 2.

Fig. 3 shows a schematic structural diagram of the region Q1 in fig. 1. As shown in fig. 3, the touch panel 100 further includes a trace 30, the trace 30 includes a first type of trace 31, the first type of trace 31 is located in the first trace area 21, the first type of trace 31 includes a first segment 311 and a second segment 312 that are alternately connected, the first segment 311 extends along a first direction X, the second segment 312 extends along a second direction Y, and the plurality of first segments 311 are arranged in the second direction Y, the plurality of second segments 312 are also arranged in the second direction Y, and the first direction X and the second direction Y intersect. The first direction X may be a column direction and the second direction Y may be a row direction. Of course, the row and column directions may also be interchanged.

It will be appreciated that the first type of trace 31 is a serpentine trace that extends generally along the second direction Y.

In this embodiment, the first type of trace 31 in the first trace area 21 adopts a serpentine trace manner, that is, adopts a serpentine trace manner in a certain range (i.e., in the range of ink fluctuation) close to the touch area 10, so that the amount of reflected light of the trace in a specific direction can be reduced, which is equivalent to dispersing the emitting surface, so that the most obvious direction is avoided, and the white edge degree can be reduced as much as possible under the condition that the ink is not covered in place, so as to improve the visual effect.

As an example, a portion of the plurality of second touch channels 12 may be located in the first touch area 101, and another portion may be located in the second touch area 102. For example, the areas of the first touch area 101 and the second touch area 102 may be equal, and the number of the second touch channels 12 in the first touch area 101 may be equal to the number of the second touch channels 12 in the second touch area 102.

As shown in fig. 2, the touch panel 100 may further include a first binding area 71 and a second binding area 72. In the first direction X, the first binding area 71 and the second binding area 72 are located on a side of the trace area 20 away from the touch area 10. The first binding area 71 and the second binding area 72 are arranged in the second direction Y. The first bonding area 71 and the second bonding area 72 may be symmetrically distributed about a center line of the touch area 10 extending along the first direction X.

The first bonding region 71 may include a plurality of first bonding terminals 711, and the plurality of first bonding terminals 711 may be arranged along the second direction Y. For example, the plurality of first bonding terminals 711 may be arranged in a row along the second direction Y.

The second binding region 72 may include a plurality of second binding terminals 722, and the plurality of second binding terminals 722 may be arranged along the first direction X. For example, the plurality of second binding terminals 722 may be arranged in a row along the second direction Y.

One end of the first type of wire 31 may be connected to the first touch channel 11, and the other end of the first type of wire 31 may be connected to any one of the first bonding terminal 711 and the second bonding terminal 722.

For example, some of the plurality of second touch channels 12 may be connected to the first bonding terminal 711 through the first type of wire 31, and another part of the second touch channels 12 may be connected to the second bonding terminal 722 through the first type of wire 31. As an example, the first touch area 101 and the first bonding area 71 are located at the left side, the second touch area 102 and the second bonding area 72 are located at the right side, and the number of the second touch channels 12 of the first touch area 101 and the second touch area 102 is the same. The second touch channel 12 of 1/2 may be connected to the first bonding terminal 711 through the first type of wire 31, and the second touch channel 12 of 1/2 may be connected to the second bonding terminal 722 through the first type of wire 31. Thus, the number of binding terminals provided by the first binding area 71 and the second binding area 72 for the second touch channel 12 may be the same, so that the number of first type wires 31 corresponding to the first binding area 71 and the second binding area 72 respectively is the same, so that the first type wires 31 are uniformly distributed, and the narrow frame is facilitated.

For example, one first touch channel 11 may be connected to the binding terminal through one wire, and one second touch channel 12 may be connected to the binding terminal through one wire, that is, the touch panel may adopt a "1T1R" design mode, in the "1T1R" design mode, the number of wires required may be relatively small, the space of the frame may be relatively sufficient, which is more beneficial for the first type wires 31 to adopt serpentine wires while giving consideration to the narrow frame.

Of course, in other examples, for example, the touch panel may be configured in a manner of "2T1R" and "2T2R", and the first type of trace 31 may also be configured to use a serpentine trace. Where "T" represents the drive channel and R represents the sense channel. "2T" means that both ends of the driving channel are connected with touch leads, and that both ends of the driving channel are connected with touch leads connected to touch terminals. Similarly, "2R" means that both ends of the sensing channel are connected with the touch leads, and both ends of the sensing channel are connected with the touch terminals

For example, as shown in fig. 3, one first type trace 31 may include a plurality of second segments 312, where adjacent second segments 312 are offset, and any two adjacent second segments 312 may have equal spacing in the first direction X.

In some embodiments, as shown in fig. 4, the linewidth of the first segment 311 is less than the linewidth of the second segment 312. The first segment 311 extends along a first direction X, and a line width of the first segment 311 refers to a width of the first segment 311 in a second direction Y. The second segment 312 extends along the second direction Y, and the line width of the second segment 312 refers to the width of the second segment 312 in the first direction X.

The line width of the first section 311 is different from the line width of the second section 312, so that the line resistance of the first type of wiring 31 can be flexibly adjusted, and the first section with small line width can be used for improving the line resistance of the first type of wiring 31.

In some embodiments, please continue to refer to fig. 4, at least a portion of the first segments 311 of the plurality of first segments 311 belonging to the same first type of trace 31 has a trace length along the first direction X smaller than a trace length along the second direction Y of the second segment 312.

As shown in fig. 4, the first type trace 31 may include a plurality of first segments 311, an end of the first segments 311 away from the touch area 10 may be leveled in the second direction Y, and an end of the first segments 311 located in the middle of the first segments 311 close to the touch area 10 may be leveled in the second direction Y. For two first segments located at the edge of the plurality of first segments 311, one first segment 311 is connected to a touch channel in the touch area 10 through a connection terminal 50, and the other first segment is used for connecting a flexible circuit board or a touch driving chip.

The first segments 311 located in the middle of the plurality of first segments 311 have the same track length along the first direction X. The routing length of the first segments 311 located in the middle among the first segments 311 is smaller than the routing length of the second segments 312 along the second direction Y in the first direction X. The trace length of two first segments located at the edge of the plurality of first segments 311 may be slightly longer.

Illustratively, the trace lengths of the plurality of second segments 312 along the second direction Y are equal.

The first section 311 extends along the first direction X, where the trace length of the first section 311 is relatively smaller, the frame of the touch panel in the first direction X may be advantageously reduced, thereby being advantageous for implementing a narrow frame.

In some embodiments, as shown in fig. 5, at least one auxiliary line 40 is also included between adjacent first segments 311 in the second direction Y. It is understood that the auxiliary line 40 is located in the first routing area 21. The auxiliary line 40 may not be connected to other wirings or structures, that is, the auxiliary line 40 may not be used to transmit signals, and the auxiliary line 40 may be referred to as a dummy line.

For example, among the plurality of second sections 312, a portion of the second sections 312 may be provided with the auxiliary line 40 on a side close to the touch area 10, and another portion of the second sections 312 may be provided with the auxiliary line 40 on a side far from the touch area 10.

The viewing efficiency is also affected if there is a blank area between adjacent first segments 311. In the embodiment of the present application, the auxiliary wire 40 is inserted between the adjacent first segments 311, so as to further improve the problem of poor visual effect.

A plurality of auxiliary wires 40 may be interposed between two adjacent first segments 311, the plurality of auxiliary wires 40 each extend along the first direction X, and the plurality of auxiliary wires 40 are arranged in the second direction Y.

For example, the line width of the first segment 311 in the second direction Y is denoted as w1, the line width of the auxiliary line 40 in the second direction Y is denoted as w2, and w2 is larger than w1.

There is a limit to the process of manufacturing the trace, and the first segment 311 may be manufactured by using the minimum line width under the process limit, that is, the line width of the first segment 311 may be the minimum, so that the resistance compensation of the first type trace 31 is advantageously realized through the first segment with the smaller line width.

If w2 is greater than w1, the auxiliary line 40 can be manufactured without using the minimum line width at the process limit, so that the process difficulty of the auxiliary line 40 can be reduced to a certain extent.

Illustratively, the spacing between the first segment 311 and the adjacent auxiliary line 40 in the second direction Y is denoted as s1, and the spacing between two adjacent auxiliary lines 40 in the second direction Y is denoted as s2, with s2 being greater than s1.

Illustratively, the dimension occupied by the first segment 311 in the second direction Y is denoted as pitch1, the dimension occupied by the auxiliary line 40 in the second direction Y is denoted as pitch2, pitch 1=w1+s1, pitch 2=w2+s2, and pitch2 > pitch1. That is, the auxiliary line 40 has a pitch2 greater than the pitch1 of the first segment 311.

The plurality of auxiliary lines 40 between adjacent first segments 311 in the second direction Y may be wired to the pitch, that is, the line widths of the plurality of auxiliary lines 40 between adjacent first segments 311 in the second direction Y are the same, and the pitches of the adjacent auxiliary lines 40 in the second direction Y are the same.

For example, the line width of the auxiliary line 40 in the second direction Y may be smaller than the line width of the second segment 312 in the first direction X.

In some embodiments, as shown in fig. 6, the first direction X and the second direction Y are perpendicular, and the first type trace 31 may further include a third section 313, where the first section 311 and the second section 313 are connected by the third section 313. That is, the third section 313 is connected between the first section 311 and the second section 313.

The third segment 313 extends along a third direction that intersects both the first direction X and the second direction Y.

In this embodiment, the first section 311 and the second section 313 are connected through the third section 313, and the extending direction of the third section 313 is intersected with the extending direction of the first section 311 and the extending direction of the second section 313, which is equivalent to adopting a large chamfer between the first section 311 and the second section 313, that is, adopting a large chamfer at the corner of the first type of serpentine wire 31, so that the corner of the first type of wire 31 is approximately arc-shaped. It can be appreciated that the right angle corner has only two surfaces, and the adoption of the large chamfer can reduce the reflection length of the two surfaces and increase the other reflection surface, thereby playing a role of dispersing the reflection angle.

For example, two third segments 313 connected by the same first segment 311 may be parallel. The extension directions of the two third segments 313 to which the same second segment 312 is connected may intersect.

For example, the first section 311, the second section 312, and the third section 313 may be located on the same film layer, and the first section 311, the second section 312, and the third section 313 may be integrally formed.

Illustratively, the first segment 311, the second segment 312, and the auxiliary line 40 may be located in the same film layer.

In some embodiments, referring to fig. 6, the trace 30 may further include a plurality of second-type traces 30, the second-type traces 30 are located in the second trace area 22, the second-type traces 32 extend along the second direction Y, and the line widths of the plurality of second-type traces 32 are equal and are equally spaced in the first direction X.

The line width of the second type of trace 32 plus the pitch between the second type of trace 32 is denoted as pitch of the second type of trace 32 in the first direction X, and it is understood that the plurality of second type of traces 32 are routed using equal pitch.

Illustratively, the line width of the second type of trace 32 in the first direction X may be greater than the line width of the first segment 311 in the second direction Y. The line width of the second type of trace 32 in the first direction X may be smaller than the line width of the second segment 312 in the first direction X. The line width of the second type wirings 32 in the first direction X may be smaller than the line width of the auxiliary lines 40 in the second direction Y.

Illustratively, at least a portion of the plurality of second-type traces 32 may be used to connect to a first touch channel of the touch pad 10.

Since the trace is of a certain thickness. The section of the wiring in the actual product is similar to a trapezoid, and the waist surface of the trapezoid can reflect light. The smaller the line width of the wiring is, the larger the waist area of the wiring in the actual product is, and the more obvious the reflection is; on the contrary, the larger the line width of the wiring is, the smaller the waist area of the wiring in the actual product is, and the less obvious the reflection is. The plurality of second-type wirings 32 are routed by using larger pitch, which is favorable for reducing the reflective metal area at two sides of the wirings of the second-type wirings 32 and reducing the reflective quantity, and in addition, the plurality of second-type wirings 32 are routed by using equal pitch, so that the visual effect of the second wiring area 22 tends to be consistent.

In some embodiments, at least some of the traces 30 may employ dual-layer metal routing. As shown in fig. 7, the trace 30 may include a first branching line 301 and a second branching line 302, where the first branching line 301 is located in a first metal layer M1, the second branching line 302 is located in a second metal layer M2, and the first metal layer M1 and the second metal layer M2 are stacked in a thickness direction of the touch panel. An insulating layer 60 may be disposed between the first metal layer M1 and the second metal layer M2. The touch panel may further include a cover plate (not shown), and the second metal layer M2 is located between the cover plate and the first metal layer M1 of the touch panel in a thickness direction of the touch panel. That is, the second metal layer M2 is close to the cover plate of the touch panel, the first metal layer M1 is far away from the cover plate of the touch panel, the second metal layer M2 is an upper metal layer, and the first metal layer M1 is a lower metal layer.

The first branch 301 is a lower metal trace, and the second branch 302 is an upper metal trace. It is appreciated that the second split line 302 is closer to the human eye, and that the reflection of light from the second split line 302 has a greater impact on visual performance.

Illustratively, the linewidth of the first line segment 301 is less than the linewidth of the second line segment 302. That is, the line width of the upper metal wiring is large. The larger the line width of the wiring is, the smaller the waist area of the wiring in the actual product is, and the less obvious the reflection is. The linewidth of the second branch line 302 is larger, and the amount of reflection light on the waist surface of the second branch line 302 can be reduced.

In some embodiments, as shown in fig. 7, the orthographic projection of the second split line 302 in the thickness direction of the touch panel covers the orthographic projection of the first split line 301 in the thickness direction of the touch panel. In this way, the influence of the reflection of light on the viewing effect of the first branching line 301 can be further weakened.

The difference between the line width of the second branch line 302 and the line width of the first branch line 301 is called a package variable, and the single-side package variable is equal to half of the difference between the line width of the second branch line 302 and the line width of the first branch line 301. Mask plates (masks) can be used in the preparation process of the first branching lines 301 and the second branching lines 302, the masks need to be aligned in the preparation process, and under the condition of inaccurate alignment, the masks have alignment Offset (OVL), and single-side package variables can be larger than the alignment offset, so that the orthographic projection of the second branching lines 302 in the thickness direction of the touch panel is guaranteed to cover the orthographic projection of the first branching lines 301 in the thickness direction of the touch panel.

Based on the same inventive concept, the application also provides a touch display panel. Fig. 8 is a schematic structural diagram of a touch display panel according to an embodiment of the present application. As shown in fig. 8, a touch display panel 1000 provided in an embodiment of the present application may include the touch panel 100 described in any of the above embodiments.

According to the touch display panel provided by the embodiment of the application, the first type of wiring in the first wiring area adopts the serpentine wiring mode, namely, the serpentine wiring mode is adopted in a certain range (namely, in the ink fluctuation range) close to the touch area, so that the quantity of reflected light of the wiring in a specific direction can be reduced, which is equivalent to dispersing the emitting surface, so that the most obvious direction is avoided, and the white edge degree can be reduced as much as possible under the condition that the ink is not covered in place, so that the visual effect is improved.

As an example, as shown in fig. 8, the touch display panel 1000 may further include a display panel 200, where the display panel 200 and the touch panel 100 are stacked, and the touch panel 100 may be located at one side of the light emitting surface of the display panel 200.

In other examples, the touch panel 100 of the touch display panel 1000 may be integrated in a display panel, for example, the display panel includes an array substrate including a plurality of metal layers stacked, at least some of the metal layers may be multiplexed into a touch metal layer and a trace of the touch panel.

For example, the Light Emitting element of the touch display panel may be an Organic Light-Emitting Diode (OLED).
