Description
Technical Field
The invention relates to the technical field of display, in particular to a touch display panel and a display device.
Background
Currently, a touch screen is the first choice for more and more mobile terminals. With the continuous enhancement of touch technology, the demand of consumers for touch screens is also increasing. Nowadays, touch screens are developing in the direction of narrow bezel and low interference, and how to realize narrow bezel and reduce impedance and interference while ensuring touch accuracy becomes a research focus.
As shown in fig. 1, fig. 1 is a schematic view of a touch panel provided in the prior art, wherein a substrate 1 has a display area AA and a sector area F located at the periphery of the display area AA, and the sector area F is used for disposing traces in the display area of the display panel and electrically connecting the traces with a driving circuit. In the existing touch screen, the following problems are formed because the touch wiring and the data line are crossed in a sector area:
1. in the sector area, the touch control routing and the data line are not overlapped, so that the capacitive coupling influence is small and the interference degree is low; however, the number of touch traces and data lines is large, which causes a large fan-shaped area and occupies much space, and is not favorable for realizing a narrow frame.
2. In the sector area, the touch routing and the data lines are completely overlapped, so that the area of the sector area can be effectively reduced, and a narrow frame is realized; however, the touch traces are sensitive to the capacitive coupling effect, and interference is easily caused under the condition that the touch traces are overlapped with other traces, so that the touch performance is affected.
3. In the sector area, the touch trace and the data line are partially overlapped, which is the same as the case where the touch trace and the data line are completely overlapped.
Therefore, a touch screen capable of realizing low interference and a narrow frame while ensuring touch accuracy is urgently needed.

In addition, the projections of the second traces 5 and the first traces 4 in the vertical direction of the first substrate 1 are not overlapped, that is, the second traces 5 and the first traces 4 are arranged in a staggered manner.

With continued reference to fig. 4, the first trace 4 has a first sub-trace 41 and a second sub-trace 42. Specifically, the first sub-traces 41 are disposed on the first wiring layer 31, and the second sub-traces 42 are disposed on the second wiring layer 32, as shown in fig. 4, the number of the first sub-traces 41 is less than the number of the second sub-traces 42. The second trace 5 is provided at the first wiring layer 31. In this embodiment, only the first sub-trace 41 is disposed on the first wiring layer 31, the second sub-trace 42 is disposed on the second wiring layer 32, and the number of the first sub-trace 41 is less than that of the second sub-trace 42. The invention may also be such that the number of the first sub-traces 41 is greater than that of the second sub-traces 42, and the second traces 5 are disposed at the second wiring layer 32. Alternatively, the first sub-trace 41 is disposed at the second wiring layer 32, and the second sub-trace 42 is disposed at the first wiring layer 31.
As shown in fig. 5, fig. 5 is a schematic cross-sectional view of a touch display panel according to an embodiment of the present invention, wherein a first sub-trace 41 is located on the first routing layer 31, a second sub-trace 42 is located on the second routing layer 42, and a second trace 5 is located on the second routing layer 32. The number of the first sub-traces 41 is greater than that of the second sub-traces 42.

In addition, a projection of the first sub-trace 41 in a vertical direction of the first substrate (not shown in the figure) overlaps a projection of the second sub-trace 42 in the vertical direction of the first substrate. That is, the first sub-trace 41 and the second sub-trace 42 have the same shape, and are completely overlapped in the vertical direction, and the projection of the first sub-trace 41 on the first substrate is identical to the projection of the second sub-trace 42 on the first substrate.
The specific wiring area 3 has the wiring unit 30, the wiring unit 30 is composed of one first sub-wiring 41, two second sub-wirings 42(42a and 42b), and one second wiring 5, and the wiring unit 30 is repeatedly arranged in the wiring area 3. In the same wiring unit 30, a projection of one second sub-trace 42a in the vertical direction of the first substrate overlaps one first sub-trace 41. As shown in fig. 4, in the wiring unit 30, the traces overlapped on the left side are the first sub-trace 41 and the second sub-trace 42a, which are completely overlapped. In addition, the projection of one second trace 5 in the first substrate vertical direction is located at a side where the projection of the other second sub-trace 42b in the first substrate vertical direction is far from the projection of the first sub-trace 41 in the first substrate vertical direction. As shown in the figure, the second trace 5 is located at the right side of the wiring region 30, and the second trace 5 is not overlapped with the first trace 4, that is, the second trace 5 is not overlapped with the first sub-trace 41, and the second trace 5 is not overlapped with the second sub-traces 42a and 42 b. In addition, the first wiring area 31 is provided with the first sub-wiring 41 and the second wiring 5, and the second wiring area 32 is provided with two second sub-wirings 42a and 42 b.
In this embodiment, one first sub-trace 41 and one second sub-trace 42a are overlapped in the vertical direction of the first substrate, and by such arrangement, the traces originally in one plane can be divided into two planes, which can effectively reduce the area of the wiring area 3 and greatly save the area of the frame. In addition, in order to reduce the influence of the coupling capacitance between the first trace 4 and the second trace 5 on the second trace 5, the second trace 5 and the first trace 4 (including the first sub-trace 41 and the second sub-traces 42a and 42b) are not overlapped or overlapped, and such an arrangement manner can not influence the second trace 5, especially, when the second trace 5 is a touch trace, the touch accuracy is influenced by the coupling capacitance and is reduced.
In other embodiments, the first sub-trace and the second sub-trace can be overlapped. As shown in fig. 7, fig. 7 is a schematic cross-sectional view of another touch display panel according to an embodiment of the invention. The basic structure of fig. 7 is substantially the same as that of fig. 4, and the description of the same parts is omitted, with the difference that: the first sub-trace 41 located in the first wiring region 31 partially overlaps with the second sub-trace 42 located in the second wiring region 32 in projection in the vertical direction of the first substrate.

I.e., the left side of the wiring unit 30 shown in fig. 8, the first sub-trace 41 and the second sub-trace 42 are overlapped in the vertical direction, and the sizes of the two sub-traces are the same. The projection of the second routing line 5 in the vertical direction of the first substrate is located between the projections of the two second sub-routing lines 42 in the vertical direction of the first substrate. That is, the two second sub-traces 42 are located in the second wiring region 32, the second trace 5 is located in the first wiring region, and the projection of the second trace 5 in the vertical direction is located between the two second sub-traces 42.

In other embodiments, the wiring unit 30 may also be as shown in fig. 9, and fig. 9 is a schematic cross-sectional view of another touch display panel according to an embodiment of the present invention. The basic structure and the action of fig. 9 and fig. 8 are basically the same, and the description of the same parts is omitted, and the difference lies in: the first sub-trace 41 and the second sub-trace 42 partially overlap in the first substrate vertical direction.
In the embodiments of fig. 4 to 9, the first sub-wires 41 and the second sub-wires 42 are overlapped, so as to achieve the purpose of reducing the wiring area 3, and satisfy the narrow frame. Meanwhile, the second wires 5 are not overlapped with any first wires, so that interference can be reduced to a certain degree, and touch precision is guaranteed.
In addition, in the above embodiment, the insulating layer 8 is disposed between the first trace 4 and the second trace 5, and the insulating layer 8 is disposed between the first sub-trace 41 and the second sub-trace 42.
