Generally, touch control has become one of the standard of many display devices, wherein capacitive touch screens are widely used, and the basic principle is to use tools such as a finger or a stylus to generate capacitance with the touch screen, and to use an electric signal formed by capacitance change before and after touch to confirm whether the panel is touched and confirm touch coordinates.
One important touch technology of capacitive touch panels is self-capacitance, i.e., a touch function is realized by a layer of metal. The touch sensing block and the touch signal line can be formed by the same layer of metal, such as a transparent oxide conductive material or a metal material such as Ti/Al/Ti (titanium/aluminum/titanium), al (aluminum) alloy, etc., and can be designed into a grid pattern.
Because the lengths of the control signal lines connected with different touch sensing blocks are different, the corresponding impedances are also different, so that a voltage difference problem can be generated, and even the touch performance can be seriously influenced.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. It will be apparent that the described embodiments are only some, but not all, embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to fall within the scope of the invention.
In the description of the present invention, it should be noted that, unless explicitly specified and limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be either fixedly connected, detachably connected, or integrally connected, for example; can be mechanically connected, electrically connected or can be communicated with each other; can be directly connected or indirectly connected through an intermediate medium, and can be communicated with the inside of two elements or the interaction relationship of the two elements. The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art according to the specific circumstances.
Fig. 1 is a schematic structural diagram of a display panel according to a first embodiment of the present invention. The display panel includes: at least one touch sensing block 10, at least one control signal line 30 and a control circuit 20.
Wherein the at least one control signal line 30 is connected with the at least one touch sensing block 10. The control circuit 20 is disposed at one end of the display panel, and the control circuit 20 is connected to the corresponding at least one touch sensing block 10 through the at least one control signal line 30. A part of the control signal lines 30 are disposed in the non-display area 50 of the display panel, and a part of the control signal lines 30 are disposed in the display area 40 of the display panel.
The touch sensing block 10 connected to the control signal line 30 located in the non-display area 50 is located in the distal area 70, and the touch sensing block 10 connected to the control signal line 30 located in the display area 40 is located in the proximal area 60. Wherein the distal region 70 is located at the opposite end of the display panel and the proximal region 60 is located at the region formed between the control circuit 20 and the distal region 70. Thus, the number of control signal lines 30 passing through the dead zone 80 is reduced, thereby reducing the width of the dead zone 80 to increase the density of the touch sensing block 10. The blind area refers to a gap area between the touch sensing blocks 10, i.e., an area where a touch function cannot be realized.
In this embodiment, the touch sensing blocks 10 are distributed in an array, and the touch sensing blocks 10 and the control circuit 20 are arranged in the same layer.
The invention has the advantages that by arranging one part of the control signal lines in the non-display area of the display panel and the other part of the control signal lines in the display area of the display panel, the number of the control signal lines in the display area is reduced, so that the density of the corresponding touch sensing blocks is improved, and the touch sensing performance is improved. In addition, because the touch sensing block connected with the control signal line in the non-display area is located in the far-end area, the control signal line in the non-display area is longer and larger, and the control signal line in the non-display area is connected with the control circuit through the via hole, so that the control signal line in the non-display area can be composed of a plurality of metal wiring layers, the equivalent signal transmission sectional area of the control signal line in the non-display area is increased, and the impedance of the control signal line in the non-display area can be reduced.
Fig. 2 is a cross-sectional view of A-A in fig. 1 according to a second embodiment of the present invention. On the basis of the first embodiment, the display panel further includes: buffer layer 21, active layer 23, gate layer 24, first gate insulating layer 22, second gate insulating layer, source drain electrode layer 25, insulating layer 27, planarization layer, anode layer 26, pixel definition layer 31, OLED device layer 32, encapsulation layer 33, barrier layer 34, and signal trace layer 28.

The first gate insulating layer 22 is disposed on the buffer layer 21, the second gate insulating layer is disposed on the first gate insulating layer 22, and the gate layer 24 is disposed on the first gate insulating layer 22 and the second gate insulating layer, respectively.

In the present embodiment, the signal trace layer 28 located in the non-display area 50 is connected to the source/drain electrode layer 25 through the via 29 to form the control signal line 30. Since the control signal line 30 of the distal end portion 70 is longer than the control signal line 30 of the proximal end portion 60, the resistance value of the control signal line 30 located in the distal end portion 70 is larger when the control signal line 30 is the same. In view of this, the control signal line 30 of the non-display area 50 adopts a multi-layer design, so that the cross-sectional area of the control signal line 30 can be increased to reduce the impedance of the control signal line 30, thereby improving the problem that the control signal line 30 cannot be driven due to the large resistance.
Referring to fig. 1 in combination, the touch sensing blocks 10 are arranged in a matrix manner and are arranged in a first direction and a second direction, specifically, the first direction is a row direction and the second direction is a column direction, and M, N respectively represents the number of the touch sensing blocks 10 in the row direction and the column direction (wherein M, N is a positive integer, m=3 and n=5 in fig. 1).
The invention has the advantages that by arranging one part of the control signal lines in the non-display area of the display panel and the other part of the control signal lines in the display area of the display panel, the number of the control signal lines in the display area is reduced, so that the density of the corresponding touch sensing blocks is improved, and the touch sensing performance is improved. In addition, because the touch sensing block connected with the control signal line in the non-display area is located in the far-end area, the control signal line in the non-display area is longer and larger, and the control signal line in the non-display area is connected with the control circuit through the via hole, so that the control signal line in the non-display area can be composed of a plurality of metal wiring layers, the equivalent signal transmission sectional area of the control signal line in the non-display area is increased, and the impedance of the control signal line in the non-display area can be reduced.
As shown in fig. 3, a third embodiment of the present invention provides a cross-sectional view at A-A in fig. 1. On the basis of the first embodiment, the display panel further includes: buffer layer 21, active layer 23, gate layer 24, first gate insulating layer 22, second gate insulating layer, source drain electrode layer 25, insulating layer 27, planarization layer, anode layer 26, pixel definition layer 31, OLED device layer 32, encapsulation layer 33, barrier layer 34, and signal trace layer 28.
The active layer 23 is disposed on the buffer layer 21 and located in the display area 40. The first gate insulating layer 22 is disposed on the buffer layer 21, the second gate insulating layer is disposed on the first gate insulating layer 22, and the gate layer 24 is disposed on the first gate insulating layer 22 and the second gate insulating layer, respectively. The insulating layer 27 is disposed on the second gate insulating layer, the planarization layer is disposed on the insulating layer 27, the source/drain electrode layer 25 is disposed on the insulating layer 27, and the anode layer 26 is disposed on the planarization layer.

In the present embodiment, the signal trace layer 28 located in the non-display area 50 is connected to the anode layer 26 through the via 29 to form the control signal line 30. Since the control signal line 30 of the distal end portion 70 is longer than the control signal line 30 of the proximal end portion 60, the resistance value of the control signal line 30 located in the distal end portion 70 is larger when the control signal line 30 is the same. In view of this, the control signal line 30 of the non-display area 50 adopts a multi-layer design, so that the cross-sectional area of the control signal line 30 can be increased to reduce the impedance of the control signal line 30, thereby improving the problem that the resistance of the control signal line 30 is large and cannot be driven. The greater the thickness of the film layer to which the control signal line 30 is connected, the lower the specific resistance, and the better the improvement effect. Therefore, the resistivity of the control signal line 30 in the third embodiment is smaller than that of the control signal line 30 in the second embodiment. Specifically, the thickness of the source-drain electrode layer 25 is greater than the thickness of the insulating layer 27, and the thickness of the insulating layer 27 is greater than the thickness of the anode layer 26.
Referring to fig. 1 in combination, the touch sensing blocks 10 are arranged in a matrix manner and are arranged in a first direction and a second direction, specifically, the first direction is a row direction and the second direction is a column direction, and M, N respectively represents the number of the touch sensing blocks 10 in the row direction and the column direction (wherein M, N is a positive integer, m=3 and n=5 in fig. 1).
The invention has the advantages that by arranging one part of the control signal lines in the non-display area of the display panel and the other part of the control signal lines in the display area of the display panel, the number of the control signal lines in the display area is reduced, so that the density of the corresponding touch sensing blocks is improved, and the touch sensing performance is improved. In addition, because the touch sensing block connected with the control signal line in the non-display area is located in the far-end area, the control signal line in the non-display area is longer and larger, and the control signal line in the non-display area is connected with the control circuit through the via hole, so that the control signal line in the non-display area can be composed of a plurality of metal wiring layers, the equivalent signal transmission sectional area of the control signal line in the non-display area is increased, and the impedance of the control signal line in the non-display area can be reduced.
As shown in fig. 4, a cross-sectional view of A-A in fig. 1 is provided in accordance with a fourth embodiment of the present invention. On the basis of the first embodiment, the display panel further includes: buffer layer 21, active layer 23, gate layer 24, first gate insulating layer 22, second gate insulating layer, source drain electrode layer 25, insulating layer 27, planarization layer, anode layer 26, pixel definition layer 31, OLED device layer 32, encapsulation layer 33, barrier layer 34, and signal trace layer 28.
The active layer 23 is disposed on the buffer layer 21 and located in the display area 40. The first gate insulating layer 22 is disposed on the buffer layer 21, the second gate insulating layer is disposed on the first gate insulating layer 22, and the gate layer 24 is disposed on the first gate insulating layer 22 and the second gate insulating layer, respectively.

Since the control signal line 30 of the distal end portion 70 is longer than the control signal line 30 of the proximal end portion 60, the resistance value of the control signal line 30 located in the distal end portion 70 is larger when the control signal line 30 is the same. In view of this, the control signal line 30 of the non-display area 50 adopts a multi-layer design, so that the cross-sectional area of the control signal line 30 can be increased to reduce the impedance of the control signal line 30, thereby improving the problem that the resistance of the control signal line 30 is large and cannot be driven. The more the control signal lines 30 are connected by the film layers, the lower the resistivity, and the better the improvement effect. Therefore, the resistivity of the control signal line 30 in the case of the fourth embodiment is smaller than that of the control signal line 30 in the cases of the second and third embodiments.
Referring to fig. 1 in combination, the touch sensing blocks 10 are arranged in a matrix manner and are arranged in a first direction and a second direction, specifically, the first direction is a row direction and the second direction is a column direction, and M, N respectively represents the number of the touch sensing blocks 10 in the row direction and the column direction (wherein M, N is a positive integer, m=3 and n=5 in fig. 1).
The invention has the advantages that one part of the control signal lines are arranged in the non-display area of the display panel, and the other part of the control signal lines are arranged in the display area of the display panel, so that the number of the control signal lines in the display area is reduced, the density of the corresponding touch sensing blocks is improved, and the touch sensing performance is improved. In addition, because the touch sensing block connected with the control signal line in the non-display area is located in the far-end area, the control signal line in the non-display area is longer and larger, and the control signal line in the non-display area is connected with the control circuit through the via hole, so that the control signal line in the non-display area can be composed of a plurality of metal wiring layers, the equivalent signal transmission sectional area of the control signal line in the non-display area is increased, and the impedance of the control signal line in the non-display area can be reduced.
Fig. 5 is a cross-sectional view of fig. 1 A-A according to a fifth embodiment of the present invention. On the basis of the first embodiment, the display panel further includes: buffer layer 21, active layer 23, gate layer 24, first gate insulating layer 22, second gate insulating layer, source drain electrode layer 25, insulating layer 27, planarization layer, anode layer 26, pixel definition layer 31, OLED device layer 32, encapsulation layer 33, barrier layer 34, and signal trace layer 28.
The active layer 23 is disposed on the buffer layer 21 and located in the display area 40. The first gate insulating layer 22 is disposed on the buffer layer 21, the second gate insulating layer is disposed on the first gate insulating layer 22, and the gate layer 24 is disposed on the first gate insulating layer 22 and the second gate insulating layer, respectively. The insulating layer 27 is disposed on the second gate insulating layer, the planarization layer is disposed on the insulating layer 27, the source/drain electrode layer 25 is disposed on the insulating layer 27, and the anode layer 26 is disposed on the planarization layer.

In this embodiment, the signal trace layer 28 in the non-display area 50 is connected to the anode layer 26 through the via 29, the anode layer 26 is connected to the source/drain electrode layer 25 through the via 29, and the source/drain electrode layer 25 is connected to the gate layer 24 through the via 29 to form the control signal line 30. Since the control signal line 30 of the distal end portion 70 is longer than the control signal line 30 of the proximal end portion 60, the resistance value of the control signal line 30 located in the distal end portion 70 is larger when the control signal line 30 is the same. In view of this, the control signal line 30 of the non-display area 50 adopts a multi-layer design, so that the cross-sectional area of the control signal line 30 can be increased to reduce the impedance of the control signal line 30, thereby improving the problem that the control signal line 30 cannot be driven due to the large resistance. The more the control signal lines 30 are connected by the film layers, the lower the resistivity, and the better the improvement effect. Therefore, the resistivity of the control signal line 30 in the fifth embodiment is smaller than that of the control signal line 30 in the second, third and fourth embodiments.

In addition, because the touch sensing block connected with the control signal line in the non-display area is located in the far-end area, the control signal line in the non-display area is longer and larger, and the control signal line in the non-display area is connected with the control circuit through the via hole, so that the control signal line in the non-display area can be composed of a plurality of metal wiring layers, the equivalent signal transmission sectional area of the control signal line in the non-display area is increased, and the impedance of the control signal line in the non-display area can be reduced.
In summary, when the control signal line 30 is connected to only a single layer, the thickness of the source/drain electrode layer 25 is greater than the thickness of the insulating layer 27, and the thickness of the insulating layer 27 is greater than the thickness of the anode layer 26. When the control signal line 30 connects only a plurality of layers, the more the number of layers connected, the lower the resistivity.
