Generally, touch control functions have become one of the standards of most display devices, and among them, capacitive touch screens are widely used, and the basic principle is to use a finger or a stylus to generate capacitance with the touch screen, and use an electrical signal generated by capacitance change before and after touch control to determine whether a panel is touched and determine touch coordinates.
An important touch technology of the capacitive touch panel is self-capacitance, i.e., a touch function is realized by a layer of metal. The touch sensing block and the touch signal line may be formed of the same metal layer, such as a transparent oxide conductive material or a metal material, such as Ti/Al/Ti (titanium/aluminum/titanium), Al (aluminum) alloy, and may be designed into a grid-like pattern.
Because the lengths of the control signal lines connecting different touch sensing blocks are different, the corresponding impedances are also different, and thus a voltage difference problem is generated, and even the touch performance may be seriously affected.

Detailed Description
The technical solution 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 is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; may be mechanically connected, may be electrically connected or may be in communication with each other; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
Fig. 1 is a schematic structural diagram of a display panel according to an 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 to 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 at least one touch sensing block 10 through the at least one control signal line 30. A portion of the control signal lines 30 is disposed in the non-display region 50 of the display panel, and a portion of the control signal lines 30 is disposed in the display region 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 end region 70 is located at the opposite end of the display panel, and the proximal end region 60 is located in the region formed between the control circuit 20 and the distal end region 70. With this arrangement, 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 blocks 10. The blind area is a gap area between the touch sensing blocks 10, i.e. an area that cannot implement a touch function.
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 disposed on the same layer.
The touch sensing panel has the advantages that one part of the control signal lines is arranged in the non-display area of the display panel, and the other part of the control signal lines is 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 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 positioned in the far-end area, the control signal line in the non-display area is longer and larger, and a through hole is formed in the non-display area, the control signal line in the non-display area is connected with the control circuit through the through hole, so that the control signal line in the non-display area can be formed by multiple layers of metal wiring layers, the equivalent signal transmission sectional area of the control signal line in the non-display area is increased, and the control signal line in the non-display area can be reduced.
Fig. 2 is a cross-sectional view taken along line 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: the organic light emitting diode display comprises a buffer layer 21, an active layer 23, a gate layer 24, a first gate insulating layer 22, a second gate insulating layer, a source drain electrode layer 25, an insulating layer 27, a flat layer, an anode layer 26, a pixel definition layer 31, an OLED device layer 32, an encapsulation layer 33, a barrier layer 34 and a signal routing layer 28.
Wherein the active layer 23 is disposed on the buffer layer 21 and located in the display region 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 flat 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 flat layer.
The pixel defining layer 31 is disposed on the flat layer, the OLED device layer 32 is disposed on the anode layer 26, the encapsulation layer 33 is disposed on the OLED device layer 32, the blocking layer 34 is disposed on the encapsulation layer 33 and the pixel defining layer 31 of the non-display region 50, and the signal wiring layer 28 is disposed on the blocking layer 34.
In the present embodiment, the signal wiring layer 28 in the non-display region 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 region 70 is longer than the control signal line 30 of the proximal end region 60, the resistance value of the control signal line 30 located at the distal end region 70 is larger in the case where the control signal lines 30 are the same. Accordingly, the control signal line 30 in the non-display area 50 adopts a multi-layer design, which increases the transmission cross-sectional area of the control signal line 30 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 large resistance.
Referring to fig. 1, the touch sensing blocks 10 are arranged in a matrix and arranged in a first direction and a second direction, specifically, the first direction is a row direction, the second direction is a column direction, and M, N respectively indicate the number of the touch sensing blocks 10 in the row direction and the column direction (where M, N is a positive integer, and M is 3, and N is 5 in fig. 1).
The touch sensing panel has the advantages that one part of the control signal lines is arranged in the non-display area of the display panel, and the other part of the control signal lines is 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 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 positioned in the far-end area, the control signal line in the non-display area is longer and larger, and a through hole is formed in the non-display area, the control signal line in the non-display area is connected with the control circuit through the through hole, so that the control signal line in the non-display area can be formed by multiple layers of metal wiring layers, the equivalent signal transmission sectional area of the control signal line in the non-display area is increased, and the control signal line in the non-display area can be reduced.
Fig. 3 is a cross-sectional view taken along line a-a in fig. 1 according to a third embodiment of the present invention. On the basis of the first embodiment, the display panel further includes: the organic light emitting diode display comprises a buffer layer 21, an active layer 23, a gate layer 24, a first gate insulating layer 22, a second gate insulating layer, a source drain electrode layer 25, an insulating layer 27, a flat layer, an anode layer 26, a pixel definition layer 31, an OLED device layer 32, an encapsulation layer 33, a barrier layer 34 and a signal routing layer 28.
Wherein the active layer 23 is disposed on the buffer layer 21 and located in the display region 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 flat 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 flat layer.

In the present embodiment, the signal wiring 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 region 70 is longer than the control signal line 30 of the proximal end region 60, the resistance value of the control signal line 30 located at the distal end region 70 is larger in the case where the control signal lines 30 are the same. Accordingly, the control signal line 30 in the non-display area 50 adopts a multi-layer design, which increases the transmission cross-sectional area of the control signal line 30 to reduce the impedance of the control signal line 30, thereby improving the problem that the control signal line 30 has a large resistance value and cannot be driven. It should be noted that the larger the thickness of the film layer connected to the control signal line 30 is, the lower the resistivity is, and the better the improvement effect is. Therefore, the resistivity of the control signal line 30 in the third embodiment is smaller than the resistivity of the control signal line 30 in the second embodiment. Specifically, the thickness of the source-drain electrode layer 25 is larger than that of the insulating layer 27, and the thickness of the insulating layer 27 is larger than that of the anode layer 26.
Referring to fig. 1, the touch sensing blocks 10 are arranged in a matrix and arranged in a first direction and a second direction, specifically, the first direction is a row direction, the second direction is a column direction, and M, N respectively indicate the number of the touch sensing blocks 10 in the row direction and the column direction (where M, N is a positive integer, and M is 3, and N is 5 in fig. 1).
The touch sensing panel has the advantages that one part of the control signal lines is arranged in the non-display area of the display panel, and the other part of the control signal lines is 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 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 positioned in the far-end area, the control signal line in the non-display area is longer and larger, and a through hole is formed in the non-display area, the control signal line in the non-display area is connected with the control circuit through the through hole, so that the control signal line in the non-display area can be formed by multiple layers of metal wiring layers, the equivalent signal transmission sectional area of the control signal line in the non-display area is increased, and the control signal line in the non-display area can be reduced.
Fig. 4 is a cross-sectional view taken along line a-a in fig. 1 according to a fourth embodiment of the present invention. On the basis of the first embodiment, the display panel further includes: the organic light emitting diode display comprises a buffer layer 21, an active layer 23, a gate layer 24, a first gate insulating layer 22, a second gate insulating layer, a source drain electrode layer 25, an insulating layer 27, a flat layer, an anode layer 26, a pixel definition layer 31, an OLED device layer 32, an encapsulation layer 33, a barrier layer 34 and a signal routing layer 28.
Wherein the active layer 23 is disposed on the buffer layer 21 and located in the display region 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 flat 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 flat layer.
The pixel defining layer 31 is disposed on the flat layer, the OLED device layer 32 is disposed on the anode layer 26, the encapsulation layer 33 is disposed on the OLED device layer 32, the blocking layer 34 is disposed on the encapsulation layer 33 and the pixel defining layer 31 of the non-display region 50, and the signal wiring layer 28 is disposed on the blocking layer 34.
In the present embodiment, the signal wiring layer 28 in the non-display region 50 is connected to the anode layer 26 through the via hole 29, and the anode layer 26 is connected to the source/drain electrode layer 25 through the via hole 29 to form the control signal line 30. Since the control signal line 30 of the distal end region 70 is longer than the control signal line 30 of the proximal end region 60, the resistance value of the control signal line 30 located at the distal end region 70 is larger in the case where the control signal lines 30 are the same. Accordingly, the control signal line 30 in the non-display area 50 adopts a multi-layer design, which increases the transmission cross-sectional area of the control signal line 30 to reduce the impedance of the control signal line 30, thereby improving the problem that the control signal line 30 has a large resistance value and cannot be driven. It should be noted that the more the control signal lines 30 are connected by the more film layers, the lower the resistivity is, and the better the improvement effect is. Therefore, the resistivity of the control signal line 30 in the scheme of the fourth embodiment is smaller than the resistivity of the control signal line 30 in the schemes of the second and third embodiments.
Referring to fig. 1, the touch sensing blocks 10 are arranged in a matrix and arranged in a first direction and a second direction, specifically, the first direction is a row direction, the second direction is a column direction, and M, N respectively indicate the number of the touch sensing blocks 10 in the row direction and the column direction (where M, N is a positive integer, and M is 3, and N is 5 in fig. 1).
The touch sensing panel has the advantages that one part of the control signal lines is arranged in the non-display area of the display panel, and the other part of the control signal lines is 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 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 positioned in the far-end area, the control signal line in the non-display area is longer and larger, and a through hole is formed in the non-display area, the control signal line in the non-display area is connected with the control circuit through the through hole, so that the control signal line in the non-display area can be formed by multiple layers of metal wiring layers, the equivalent signal transmission sectional area of the control signal line in the non-display area is increased, and the control signal line in the non-display area can be reduced.
Fig. 5 is a cross-sectional view taken along line a-a in fig. 1 according to a fifth embodiment of the present invention. On the basis of the first embodiment, the display panel further includes: the organic light emitting diode display comprises a buffer layer 21, an active layer 23, a gate layer 24, a first gate insulating layer 22, a second gate insulating layer, a source drain electrode layer 25, an insulating layer 27, a flat layer, an anode layer 26, a pixel definition layer 31, an OLED device layer 32, an encapsulation layer 33, a barrier layer 34 and a signal routing layer 28.
Wherein the active layer 23 is disposed on the buffer layer 21 and located in the display region 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 flat 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 flat layer.
The pixel defining layer 31 is disposed on the flat layer, the OLED device layer 32 is disposed on the anode layer 26, the encapsulation layer 33 is disposed on the OLED device layer 32, the blocking layer 34 is disposed on the encapsulation layer 33 and the pixel defining layer 31 of the non-display region 50, and the signal wiring layer 28 is disposed on the blocking layer 34.
In the present embodiment, the signal wiring layer 28 in the non-display region 50 is connected to the anode layer 26 through the via hole 29, the anode layer 26 is connected to the source and drain electrode layer 25 through the via hole 29, and the source and drain electrode layer 25 is connected to the gate layer 24 through the via hole 29 to form the control signal line 30. Since the control signal line 30 of the distal end region 70 is longer than the control signal line 30 of the proximal end region 60, the resistance value of the control signal line 30 located at the distal end region 70 is larger in the case where the control signal lines 30 are the same. Accordingly, the control signal line 30 in the non-display area 50 adopts a multi-layer design, which increases the transmission cross-sectional area of the control signal line 30 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 a large resistance value. It should be noted that the more the control signal lines 30 are connected by the more film layers, the lower the resistivity is, and the better the improvement effect is. Therefore, the resistivity of the control signal line 30 in the fifth embodiment is smaller than the resistivity of the control signal line 30 in the second, third, and fourth embodiments.
Referring to fig. 1, the touch sensing blocks 10 are arranged in a matrix and arranged in a first direction and a second direction, specifically, the first direction is a row direction, the second direction is a column direction, and M, N respectively indicate the number of the touch sensing blocks 10 in the row direction and the column direction (where M, N is a positive integer, and M is 5 and N is 3 in fig. 1).
The touch sensing panel has the advantages that one part of the control signal lines is arranged in the non-display area of the display panel, and the other part of the control signal lines is 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 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 positioned in the far-end area, the control signal line in the non-display area is longer and larger, and a through hole is formed in the non-display area, the control signal line in the non-display area is connected with the control circuit through the through hole, so that the control signal line in the non-display area can be formed by multiple layers of metal wiring layers, the equivalent signal transmission sectional area of the control signal line in the non-display area is increased, and 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 that of the insulating layer 27, and the thickness of the insulating layer 27 is greater than that 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.
