Detailed Description

The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

Currently, touch technology has penetrated into various fields of life to production, such as ATM machines, cell phones, smart bracelets, car-mounted, AR/VR, machine dashboards, etc. The development of touch technology has led to various technologies, such as resistive touch, surface capacitive touch, projected capacitive touch, infrared touch, optical touch, surface acoustic wave touch, acoustic pulse touch, electromagnetic active pen touch, capacitive active pen touch, etc. Among them, projected capacitive is the most widely used touch technology at present. In order to meet the development trend of increasingly thinner display products, the projected capacitive Touch technology gradually develops from external Touch to embedded Touch, and an external Touch structure (Out cell Touch) mainly comprises a display module and a Touch module, wherein the two modules are two relatively independent devices, and then the two devices are integrated through a back-end laminating process, so that the thickness of the product can be influenced by the external Touch structure, and the development trend of increasingly thinner Touch display products is not met; an In/out embedded structure (In/On cell Touch) embeds a Touch module into a display module, so that the two modules are integrated together, and the product is light and thin.

The In-cell is formed by manufacturing a touch electrode between a color film substrate (CF) and an array substrate (TFT); the external embedded touch (On-cell) is to make the touch electrode On one side of the color film substrate far away from the liquid crystal layer, the external embedded touch technology also comprises two technologies of Mloc (Multi-layer On cell) and Sloc (Single-layer On cell), and the Sloc (Single-layer On cell) technology is adopted widely because the exposure process is only needed once, and the process flow is simpler.

However, in the related art, in the actual product design, due to the limitation of the narrow frame, under the premise of meeting the requirement of the touch IC on the Sloc pattern routing impedance, redundant FPC pins are added in the design of the FPC in the display device to expand the routing space on the display substrate, and due to the fact that the redundant FPC pins are not connected with the routing to the display area, an empty area without routing coverage can appear in the area corresponding to the redundant FPC pins, when external light irradiates on the surface of the product, the inconsistent brightness of the routing area and the empty area can be observed, so that the actual product has the adverse phenomena of external leakage and uneven display of the routing.

In view of this, an embodiment of the present application proposes a display substrate, fig. 1 shows a schematic structural diagram of a touch layer of a display panel according to an embodiment of the present application, as shown in fig. 1, where the display substrate includes a display area A1 and a non-display area A2, the non-display area A2 is disposed on at least one side of the display area A1, the non-display area A2 includes at least one routing area a21 and a non-routing area a22 that are arranged at intervals, an interface of an FPC circuit board is disposed in the routing area a21, and the routing area a21 is used to implement connection between the interface of the FPC circuit board and the display area A1; the non-wiring area A22 is internally provided with a redundant (dummy) FPC interface, and the non-wiring area A22 is used as an empty area corresponding to the redundant (dummy) FPC interface and is used for expanding the wiring space of a connecting line between the interface of the FPC circuit board and the display area A1.

In this embodiment, fig. 7a shows a schematic view of a B-B 'cross-section position of a display substrate according to an embodiment of the present application, fig. 7B shows a schematic view of a cross-section of a display substrate according to an embodiment of the present application at B-B', and as shown in fig. 7a and fig. 7B, the display substrate includes: a substrate base plate 11; a touch layer 12, wherein the touch layer 12 is disposed on one side of the substrate 11. As shown in fig. 1, the touch layer 12 is provided with a plurality of first connection lines 121 in the routing area a21, and the first connection lines 121 are electrically connected with the display area A1. A plurality of first pins 124 are disposed in the routing area a21, the plurality of first pins 124 are disposed on a side, far away from the display area A1, in the routing area a21, and the first pins 124 are used as an interface of the FPC board to form connection with the display area A1 through the first connection lines 121.

The first gaps exist between two adjacent first connecting lines 121, and the first gaps in the routing area a21 and the connecting lines of the non-routing area a22 are not provided with the touch layer 12, so that when the area provided with the connecting lines and the area not provided with the connecting lines are inconsistent in brightness when receiving the irradiation of external light, specifically, the first connecting lines 121 in the routing area a21 in the touch layer 12 are represented as bright line areas, the first gaps and the non-routing area a22 are all represented as dark areas, the dark areas are close to the color of the cover plate of the display product, and the color difference between the bright line areas and the cover plate of the display product is large, so that the display product is represented as uneven display bad on a macroscopic level. Therefore, in the embodiment of the present application, in order to reduce the brightness gap between the touch layer area where no connection line is disposed and the first connection line 121, a plurality of redundant lines 123 are disposed in the touch layer 12, the redundant lines 123 fill the first gap in the routing area a21, and fill the non-routing area a22 in the non-routing area a22, and the redundant lines 123 are insulated from the display area A1 and the first connection line, and adjacent redundant lines 123 are insulated from each other.

It should be noted that, in the embodiment of the present application, the touch layer 12 is an ITO film layer, the pattern and the wiring on the touch layer 12 are both ITO film layer materials, and the first pin 124 is disposed on one side of the display panel close to the FPC circuit board, so that the side with the non-routing area a22 is the side close to the FPC circuit board, the ITO film layer in the non-display area A2 on the side with the non-routing area a22 in the display area A1 is uneven, and the ITO film layer in the non-display area A2 on the other three sides without the non-routing area a22 in the display area A1 is even.

According to the embodiment of the application, the redundant wires 123 are arranged in the area where the dark area can appear when being irradiated by external light (namely, the area where no connecting wire is arranged in the touch layer 12), and mutual insulation between the redundant wires 123, between the redundant wires 123 and the connecting wire 121 and between the display area A1 is ensured, so that the area where the dark area can appear originally (the first gap in the wiring area A21 and the non-wiring area A22) is filled with the redundant wires 123 under the condition that the connecting effect of the connecting wire is not influenced, and the redundant wires 123 and the connecting wire 121 are ITO film layers of the touch layer 12, so that the external light irradiates the redundant wires 123 and the bright wire area with the same brightness on the connecting wire 121, and therefore, color difference is effectively reduced, and uneven display defects of wiring leakage and display are eliminated. Alternatively, the sum of the widths of the redundant line 123 along the arrangement direction of the display area A1 and the non-display area A2 is greater than or equal to 200 μm and less than or equal to 300 μm, and within this range, it is possible to ensure that the external light irradiates the bright line area where both the redundant line 123 and the connecting line 121 show the same brightness.

In an alternative implementation, fig. 2 shows a schematic diagram of a redundant line area in a non-routing area according to an embodiment of the present application, as shown in fig. 1 and fig. 2, the redundant lines 123 are arranged along a first direction, each of the redundant lines 123 includes at least one redundant unit 1231 arranged along a second direction, and a second gap 1232 exists between two adjacent redundant units 1231 along the second direction. The first direction and the second direction are perpendicular to each other, one of the first direction and the second direction is a direction in which the display area A1 and the non-display area A2 are arranged, and the other is a direction perpendicular to a direction in which the display area A1 and the non-display area A2 are arranged. Further, the width of the second gap 1232 is greater than or equal to 10 μm and less than or equal to 20 μm, and the width of the second gap 1232 is, illustratively, 10 μm.

In addition, the redundant lines 123 having at least two redundant units 1231 each have at least one second gap 1232, and if the second gaps 1232 included in the redundant lines 123 are on the same straight line, the visual effect of the second gaps of the redundant lines arranged in succession may be elongated, so that the bright line area caused by the second gaps included in the redundant lines 123 located on the same straight line appears when viewed on a macroscopic level, resulting in poor display of the display drain line. Therefore, in the embodiment of the present application, as shown in fig. 2, the orthographic projections of at least two second gaps 1232 on the substrate 11 are not located on the same straight line, and preferably, the orthographic projections of the second gaps 1232 included in any two redundant lines 123 on the substrate 11 are not located on the same straight line. As shown in fig. 7a and 7B, the cross section along B-B 'passes through the second gap 1232 of one of the redundant lines 123, while the second gap 1232 of the adjacent redundant line 123 is not on the cross section of B-B', and the gaps of the adjacent two redundant lines in the first direction are smaller than the width of the second gap 1232 in the first direction, so that the orthographic projections of at least two of the second gaps 1232 on the substrate 11 are not on the same straight line.

Taking the direction shown in fig. 1 and 2 as an example, the orthographic projection of the redundancy unit 1231 on the substrate 11 is rectangular, the first direction is the horizontal direction (the width direction of the rectangle), the second direction is the vertical direction (the length direction of the rectangle), the redundancy lines 123 are arranged along the horizontal direction, and the plurality of redundancy units 1231 included in each redundancy line 123 are arranged along the vertical direction. It should be noted that the foregoing examples are only an alternative way given for those skilled in the art to better understand the solution of the present application, and the specific arrangement direction and the quadrilateral shape of the redundant units may be determined according to the actual situation, which is not limited herein.

Further, as shown in fig. 2, the redundant lines 123 in the non-routing area a22 include a first redundant line 123-1 and a second redundant line 123-2, where the first redundant line 123-1 and the second redundant line 123-2 are respectively arranged at intervals along the first direction, and each of the second redundant lines 123-2 is disposed between adjacent first redundant lines 123-1, that is, the second redundant line 123-2 is disposed in a gap formed by the first redundant lines 123-1. Wherein the widths of the first redundancy line 123-1 and the second redundancy line 123-2 along the first direction are different, and the widths of the first redundancy line 123-1 and the second redundancy line 123-2 along the second direction are the same or different.

Since the second lead 125 is not used for connecting with the display area A1, the redundant line 123 disposed in the non-wiring area a22 is only used for filling the non-wiring area a22, so as to reduce the difference in display brightness between the non-wiring area a22 and the connection 121 in the wiring area a21 when the external light irradiates the touch layer 12, and the redundant line 123 disposed in the non-wiring area a22 is not used for connecting the display area A1 with the second lead 125, so that the second lead 125 and the redundant line 123 are insulated from each other.

In an alternative embodiment, the first redundancy lines 123-1 are disposed in one-to-one correspondence with the second pins 125, the second redundancy lines 123-2 are disposed between the first redundancy lines 123-1, and the widths of the first redundancy lines 123-1 and the second redundancy lines 123-2 along the first direction are different. To further simplify the manufacturing process, the width of the first redundancy line 123-1 along the first direction is the same as the width of the second pin 125 along the first direction; the width of the second redundancy line 123-2 along the first direction is smaller than the width of the second pin 125 along the first direction, specifically, the width of the second redundancy line 123-2 along the first direction is 0.5-0.8 times the width of the second pin 125 along the first direction. Alternatively, the width of the first redundancy line 123-1 in the first direction is greater than or equal to 120 μm and less than or equal to 180 μm; the width of the second redundancy line 123-2 in the first direction is greater than or equal to 60 μm and less than or equal to 144 μm; preferably, the width of the first redundancy line 123-1 in the first direction is 150 μm, and the width of the second redundancy line 123-2 in the first direction is greater than or equal to 75 μm and less than or equal to 120 μm.

In an alternative implementation, fig. 6 shows a schematic diagram of a redundant unit structure having the same shape as the second connection line according to an embodiment of the present application, and as shown in fig. 6, since the second connection line 122 is disposed on the same layer as the redundant line 123, in order to simplify the manufacturing process, the shape of the orthographic projection of the redundant unit 1231 on the substrate 11 is the same as the shape of the orthographic projection of the second connection line 122 on the substrate 11; when the second direction is the arrangement direction of the display area A1 and the non-display area A2, and the first direction is a direction perpendicular to the arrangement direction of the display area A1 and the non-display area A2, the width of the redundancy unit 1231 along the first direction is the same as the width of the second connection line along the first direction.
