[0055] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0056] The terms "first", "second" etc. in the embodiments of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequential order. In addition, the terms "comprise" and "have" and any deformation thereof are intended to cover non-exclusive inclusions, such as, the process, method, system, product or equipment comprising a series of steps or units need not be limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or that are intrinsic to these processes, methods, products or equipment. In addition, "and / or" is used in the present application to represent at least one of connected objects, such as A and / or B and / or C, and represents comprising independent A, independent B, independent C, and A and B all exist, B and C all exist, A and C all exist, and 7 situations that A, B and C all exist.

[0057] An embodiment of the present application provides a display substrate.

[0058] In one embodiment, the display substrate includes a substrate, and scan lines and data lines disposed on the substrate.

[0059] like Figures 1 to 4 As shown, in some embodiments, the display substrate includes a first area 101, a second area 102 and a third area 103, for example: the third area 103 includes a fan-out area 103, the first area 101 and the fan-out area 103 are connected by a first connecting portion 104, and the first area 101 and the second area 102 are connected by a second connecting portion 105.

[0060] The third area 103 can be used to implement signal transmission of the display substrate. For example, the third area 103 includes a fan-out area 103, and the fan-out area 103 is used to implement signal transmission of the display substrate. In this embodiment, the display driver chip 108 and the touch chip 109 are exemplarily shown in the fan-out area 103, but this does not mean that the display driver chip 108 and the touch chip 109 must be set in the fan-out area 103.

[0061] Of course, the third area 103 can also be used to implement signal line testing on the display substrate. For example, the third area 103 can also be provided with a test pad or a test circuit to test the signal lines (eg, data lines) of the first area 101 .

[0062] For example, the display driver chip 108 and the touch chip 109 may be bound to the fan-out area 103, or the display driver chip 108 and the touch chip 109 may be connected to the signal lines on the fan-out area only through the connection cables bound to the fan-out area 103. The signal lines include at least one of a data line, a touch signal line, a scan line, an initial signal line, a clock signal line, and a power signal line (e.g., a high-level VDD line and a low-level signal line VSS line).

[0063] In the technical solution of this embodiment, the substrate is made of a flexible material, so that the display substrate can adapt to a certain degree of deformation.

[0064] Exemplarily, both the first connection portion 104 and the second connection portion 105 can be used for bending or folding. For example, the first connection portion 104 and / or the second connection portion 105 can be folded to the corresponding positions in the first region 101 or the second region 102. As Figures 5A to 5C shown, in an embodiment, the display substrate is applied to a smart watch, and the smart watch includes a main display area 51 serving as a dial, and a peripheral area 52 surrounding the dial. The peripheral area 52 and the main display area 51 are located on different planes.

[0065] Of course, the display substrate can also be used in other display products. For example: mobile phones, notebooks, TVs, instrument panels of cars, central control screens, rearview mirrors for reversing, multimedia display products for the co-pilot, head-up display products, multimedia display products for headrests, sitting posture status display products, environmental status display products, electrical appliance expansion status display products, occupant interaction display products, etc.

[0066] In an exemplary embodiment, the main display area 51 serving as a dial can be in different shapes such as circular, rectangular, rounded rectangular, oval, etc. In this embodiment, the circular shape is used as an exemplary illustration.

[0067] As Figure 5A shown, the peripheral area 52 is distributed along the direction surrounding the main display area 51. It can be understood that the peripheral area 52 surrounds a part of the main display area 51, and the area not surrounded by the peripheral area 52 forms the fan-out area 103 of the corresponding display substrate.

[0068] The angle between the peripheral area 52 and the plane where the main display area 51 is located is greater than 0 degrees. In other words, the peripheral area 52 is inclined at a certain angle with respect to the main display area 51.

[0069] When the display substrate is attached to the transparent cover plate, the orthographic projection of the main display area 51 on the display substrate is located within the first region 101, and the orthographic projection of the peripheral area 52 on the display substrate is located within the second region 102. That is to say, the first region 101 of the display substrate corresponds to the main display area 51 of the smart watch, and the second region 102 of the display substrate is attached to the peripheral area 52 of the display device along a direction inclined with respect to the main display area 51.

[0070] Since there is a certain angle between the surfaces of the first region 101 and the second region 102, during the attachment process, the display substrate is bent at the first connection portion 104 and the second connection portion 105 to make the first region 101 attached to the main display area 51 of the display device, and the second region 102 attached to the peripheral area 52 of the display device.

[0071] In some of these embodiments, the display substrate includes a first signal line (e.g., a scan line) located in the first region 101 and a second signal line (e.g., a data line) located in the first region 101. Here, the first signal line and the second signal line can be signal lines for transmitting different signals. For example: the first signal line refers to one of a data line, a touch signal line, a scan line, an initial signal line, a clock signal line, and a power supply signal line; the second signal line refers to another one of a data line, a touch signal line, a scan line, an initial signal line, a clock signal line, and a power supply signal line.

[0072] In some of these embodiments, mainly taking the first signal line including a scan line and the second signal line including a data line as an example for introduction. For example: the scan line includes a first scan line 107 located in the first region 101, the data line includes a first data line 106 located in the first region 101, the first scan line 107 extends along a first direction and is arranged along a second direction, the first data line 106 extends along the second direction and is arranged along the first direction, and the first direction and the second direction are mutually intersecting directions.

[0073] In some of these embodiments, the scan line includes a first scan line 107 located in the first region 101, the data line includes a first data line 106 located in the first region 101, the first scan line 107 extends along a first direction and is arranged along a second direction, the first data line 106 extends along the second direction and is arranged along the first direction, and the first direction and the second direction are mutually intersecting directions.

[0074] As Figure 1 shown, in some of these embodiments, the display substrate further includes a first touch electrode 115 disposed in the first region 101 and a second touch electrode 110 disposed in the second region 102. The first touch electrode 115 and the second touch electrode 110 are independent of each other, and the first touch electrode 115 is connected to the touch chip 109 through a touch signal line disposed on the substrate.

[0075] In the technical solution of this embodiment, the first touch electrode 115 is used to implement touch control during the operation of the display device. Reference can be made to related technologies to a certain extent, and no further limitations will be made here.

[0076] In this embodiment, a second touch electrode 110 located in the second region 102 is further provided. In some of these embodiments, the second touch electrode 110 is a self-capacitance touch electrode. In this way, the setting difficulty of the second touch electrode 110 is lower.

[0077] In this embodiment, the number of the second touch electrodes 110 can be one. It can be understood that all of the second region 102 corresponds to one touch control signal. Exemplarily, it can correspond to a power on / off control signal, and then the second region 102 is used as the power on / off key of the display device.

[0078] In some other embodiments, the number of the second touch electrodes 110 is plural, and the second touch electrodes 110 are independent of each other. In this way, the second area 102 can replace a plurality of control buttons.

[0079] In an exemplary embodiment, the number of the second touch electrodes 110 includes three, and the three second touch electrodes 110 respectively correspond to volume up, volume down, and power on / off. In another embodiment, the number of the second touch electrodes 110 is five, and the five second touch electrodes 110 respectively correspond to brightness up, brightness down, volume up, volume down, and power on / off. During implementation, the number of the second touch electrodes 110 and the functions corresponding to the second touch electrodes 110 can be set according to needs.

[0080] The second touch electrodes 110 are also connected to a touch chip 109 located in the fan-out area 103 through touch signal lines disposed on the substrate.

[0081] In one embodiment, the touch signal traces corresponding to the second touch electrodes 110 extend from the second area 102 through the second connection portion 105 to the first area 101, and the touch signal lines can extend along the edge of the first area 101 to the first connection portion 104, and then are connected to the touch chip 109 located in the fan-out area 103.

[0082] In another embodiment, the touch signal traces corresponding to the second touch electrodes 110 extend from the second area 102 through the second connection portion 105 to the first area 101, and the touch signal lines can extend along a straight line or a broken line direction through the central area of the first area 101 to the first connection portion 104, and then are connected to the touch chip 109 located in the fan-out area 103.

[0083] In some embodiments, the first touch electrodes 115 are also connected to the touch chip 109 located in the fan-out area 103 through touch signal lines disposed on the substrate. For example, the first touch electrodes 115 can form an annular structure around the first area 101.

[0084] It can be understood that the annular structure can be a complete ring, that is, the first touch electrodes 115 surround the first area 101 to form a complete ring; the first touch electrodes 115 can also be a part of the complete ring.

[0085] During implementation, the routing positions of the touch signal lines can be reasonably arranged according to needs, and no further limitation and description are made here.

[0086] In some embodiments, the first touch electrodes 115 and the second touch electrodes 110 can be controlled by the same touch chip 109.

[0087] In some other embodiments, the first touch electrode 115 and the second touch electrode 110 are respectively connected to different touch chips 109 and are driven by different touch chips 109.

[0088] It should be understood that when the second touch electrode 110 is used as a switch key, if the display device is in the off state, the touch chip 109 will also be in the power-off state, which causes the power-on operation to not be recognized normally. If the touch chip 109 always remains in the standby state, it will result in relatively high power consumption.

[0089] In this embodiment, the first touch electrode 115 and the second touch electrode 110 can be driven by different touch chips 109. The touch chip 109 corresponding to the first touch electrode 115 disposed in the main display area 51 can only work normally when the display device is in the working state; the touch chip 109 corresponding to the second touch electrode 110 remains in the standby state when the display device is in the off state, so that the power-on instruction can be monitored through the second touch electrode 110.

[0090] In some of these embodiments, the standby power consumption of the touch chip 109 corresponding to the second touch electrode 110 is less than that of the touch chip 109 corresponding to the first touch electrode 115. In this embodiment, since the second touch electrode 110 only needs to identify the touch signals for power on and off, therefore, compared with the touch operations on the main display area 51, the requirements for the touch accuracy of the second touch electrode 110 are relatively low. Therefore, a touch chip 109 with relatively low cost and standby power consumption can be selected, which helps to reduce costs and extend the standby time while ensuring the normal realization of the power on and off functions.

[0091] In some embodiments, only one fan-out area 103 can be provided, and the touch chip 109 and the display driver chip 108 are connected to the display substrate through the same fan-out area 103.

[0092] In some other embodiments, the number of fan-out areas 103 is multiple, and the touch chip 109 and the display driver chip 108 are connected to the display substrate through different fan-out areas 103.

[0093] As Figures 1 to 4 shown, in this embodiment, setting one fan-out area 103 is used as an exemplary illustration. It should be understood that if multiple fan-out areas 103 need to be set, the setting method of the fan-out area 103 in this embodiment can be referred to, and only the number of fan-out areas 103 needs to be increased.

[0094] In this embodiment, the first direction is taken as the horizontal direction (or row direction) of the display substrate, and the second direction is taken as the vertical direction (or column direction) of the display substrate for exemplary illustration. It should be noted that the first direction and the second direction can be adjusted and are not limited thereto.

[0095] As shown in Figure 1 and Figure 2 shown, in some embodiments, the fan-out region 103 is disposed at one end of the first region 101 along the second direction, and the second region 102 is disposed at the other end of the first region 101 along the second direction. In other words, the fan-out region 103 and the second region 102 are respectively disposed at opposite ends of the first region 101, or it can be understood that the fan-out region 103 and the second region 102 are respectively disposed at both ends of the extending direction of the first data line 106.

[0096] One end of each first data line 106 close to the fan-out region 103 extends into the fan-out region 103 via the first connection portion 104 and is connected to the display driving chip 108 disposed in the fan-out region 103.

[0097] Optionally, the second region 102 is arc-shaped, the length of the second region 102 along the arc direction is less than the perimeter of the first region 101, both ends of the second region 102 extend along the direction surrounding the first region 101 from the second connection portion 105, and the distance between the second region 102 and the first region 101 increases as the minimum distance from the second connection portion 105 increases.

[0098] Please refer to Figures 1 to 4 , at each position of the second region 102, as the distance from the second connection portion 105 increases, the minimum distance between this position and the first region also gradually increases.

[0099] As shown in Figure 3 and Figure 4 shown, in some other embodiments, the fan-out region 103 is disposed at one end of the first region 101 along the second direction, the number of the second regions 102 is two, and the two second regions 102 are respectively disposed at opposite ends of the first region 101 along the first direction. The second region 102 is arc-shaped, the length of the second region 102 along the arc direction is less than half of the perimeter of the first region 101, both ends of the second region 102 extend along the direction surrounding the first region 101 from the second connection portion 105, and the distance between the second region 102 and the first region 101 increases as the minimum distance from the second connection portion 105 increases.

[0100] In this way, in this embodiment, when the display substrate is attached to the transparent cover plate, the second region 102 is attached to the peripheral region 52, and the second region 102 can adapt to the angle between the peripheral region 52 and the main display region 51, which helps to improve the attachment effect between the display substrate and the transparent cover plate.

[0101] As shown in Figures 1 to 4As shown, in some embodiments, each second region 102 is symmetrically arranged with respect to the second connection portion 105. When there are multiple second regions 102, the multiple second regions 102 may be symmetrically distributed about an axis of the first region 101, which helps to reduce the maximum distance between the end of the second region 102 and the second connection portion 105, thereby helping to improve the fitting effect between the display substrate and the transparent cover plate.

[0102] In some embodiments, the sizes of the multiple second regions 102 may be different. For example: Figure 3 As shown, the lengths of the second regions 102 located on the first side (e.g., the left side) of the first region 101 and the second regions 102 located on the second side (e.g., the right side) of the first region 101 are not equal. It can be understood that in some embodiments, the size may be at least one of length, width, area, thickness, etc. If there is a specific description of the size in the embodiment, it shall prevail according to the specific description.

[0103] In the technical solution of this embodiment, the peripheral area 52 of the display device may display an image or may not display an image.

[0104] In the case where the peripheral area 52 does not display an image, only touch electrodes may be provided in the second region 102 of the display substrate, and touch control can be achieved through the second region 102.

[0105] In the case where the peripheral area 52 displays an image, corresponding scan lines and data lines may also be provided in the second region 102 to drive the peripheral area 52 to display an image.

[0106] In some embodiments, the data line includes a second data line 111 located in the second region 102, and the second data line 111 extends in an arc along the length direction of the arc-shaped second region 102. The scan line includes a second scan line 114 located in the second region 102, and multiple second scan lines 114 are arranged in sequence along the length direction of the second region 102.

[0107] In this embodiment, each second scan line 114 extends substantially along the radial direction of the arc-shaped second region 102, while the second data line 111 extends along the length direction of the arc-shaped second region 102, so as to adapt to the shape of the second region 102.

[0108] In some embodiments, the first data line 106 includes a target data line, and each second data line 111 is connected in series with the target data line. In this way, the display control of the peripheral area 52 can be realized by using the display driving chip 108 corresponding to the first data line 106.

[0109] In some embodiments, the target data line and the second data line 111 are connected by a data line connection trace 112.

[0110] The data line connection trace 112 is connected to the target data line at one end opposite to the fan-out region 103 in the first region 101, and the data line connection trace 112 is connected to the second data line 111 at the end in the length direction of the second region 102.

[0111] As Figure 2 shown, in this embodiment, the end of the target data line is adjacent to the second connection portion 105, so the data line connection trace 112 can directly extend to the second region 102.

[0112] As Figure 4 shown, in some other embodiments, there is a certain gap between the end of the target data line and the second connection portion 105, then the data line connection trace 112 can first diffract along the edge of the first region 101 to extend to the second connection portion 105, and then extend to the second region 102 via the second connection portion 105.

[0113] In the second region 102, the data line connection trace 112 first extends along the edge of the second region 102 to one end in the arc length direction of the second region 102, and then is connected to the second data line 111 located at the end of the second region 102.

[0114] In some of these embodiments, other signal lines on the display substrate can also adopt the data line routing method. The other signal lines can be at least one of: touch signal lines, scan lines, initial signal lines, clock signal lines, power signal lines (such as: high-level VDD, low-level signal line VSS), etc.

[0115] For example: in some of these embodiments, the scan lines on the display substrate include the first scan line 107 located in the first region 101, the data lines include the first data line 106 located in the first region 101, the first scan line 107 extends along the first direction and is arranged along the second direction, the first data line 106 extends along the second direction and is arranged along the first direction, and the first direction and the second direction are mutually intersecting directions.

[0116] In some of these embodiments, other signal lines on the display substrate can also be routed with reference to the routing method of the above-mentioned second data line 111. Exemplarily, the power signal line can also be set with reference to the routing method of the second data line. The other signal lines can be at least one of: touch signal lines, scan lines, initial signal lines, clock signal lines, power signal lines (such as: high-level VDD, low-level signal line VSS), etc.

[0117] In some other embodiments, it is also possible to consider swapping the routing methods of the second scan line and the second data line, that is, the second scan line extends along the arc length direction of the second region, while the second data line extends along the radial direction of the arc of the second region.

[0118] During implementation, after the second data line extends to the second connection part, it extends in the reverse direction along the arc length of the second region for a certain length, then bends in the radial direction of the second region, and extends along the radial direction of the second region.

[0119] In some embodiments, the display substrate further includes a display driving chip 108 and a control unit 113 (exemplarily, it can be a scan control unit Gate GOA and / or a light emission control unit EM GOA). The data line is connected to the display driving chip 108, each scan line is connected to a control unit 113, and the control units 113 are cascaded in sequence.

[0120] Specifically, when the display function needs to be implemented in the second region 102, the second data line 111 in the second region 102 is connected to the target data line in the first data line 106, and the first data lines 106 are all connected to the display driving chip 108 to obtain data signals.

[0121] Each first scan line 107 and second scan line 114 are connected to a control unit 113, and the control units 113 corresponding to the first region 101 and the control units 113 corresponding to the second region 102 are cascaded in sequence, so as to control the main display area 51 and the peripheral area 52 to display images.

[0122] In this embodiment, the peripheral area 52 can be used to display notification prompt information. Exemplarily, when the display device receives a message, the display device is powered on or off, etc., different images can be controlled to be displayed in the peripheral area 52. Exemplarily, they can be different colorful images, etc., to prompt the existence of corresponding messages, etc. When the peripheral area 52 does not need to display an image, a specific image can be made to be displayed in the peripheral area 52. Exemplarily, a high potential can be provided for the second data line 111 to make the peripheral area 52 display a fixed black screen.

[0123] In some embodiments, along the direction of surrounding the first region 101, the size of the first connection part 104 is larger than the size of the second connection part 105; or, the size of the first connection part 104 is smaller than the size of the second connection part 105. For example: along the extending direction of the data line, the length of the first connection part 104 is greater than the length of the second connection part 105.

[0124] In some embodiments, the size of the first connection part 104 is smaller than the size of the second region 102; and / or, the size of the second connection part 105 is smaller than the size of the second region 102.

[0125] In some embodiments, along the direction surrounding the first region 101, the size (e.g., width) of the first connection portion 104 can be understood as the size (e.g., width) of the boundary between the first connection portion 104 and the first region 101. Similarly, along the direction surrounding the first region 101, the size of the second connection portion 105 can be understood as the size of the boundary between the second connection portion 105 and the first region 101. Since the number of data lines in the first region 101 and the second region 102 is different, the number of traces to be provided in the second connection portion 105 is less than the number of traces to be provided in the first connection portion 104. Correspondingly, the size of the first connection portion 104 is reduced, which helps to increase the aperture ratio of the display device and helps to improve the brightness of the display device.

[0126] In some embodiments, along the direction surrounding the first region 101, the size (e.g., width) of the fan-out region 103 is greater than the size (e.g., width) of the first connection portion 104. Exemplarily, referring to Figure 1 an edge above the fan-out region 103 in, it can be understood that the position of the common edge between the fan-out region 103 and the first connection portion 104 has a longer side length of the fan-out region 103. In this way, by reducing the size of the first connection portion 104 along the direction surrounding the first region 101, it helps to reduce the size of the wrinkles generated by the bending of the first connection portion 104 during the bonding process of the display substrate, and helps to improve the display effect.

[0127] In some embodiments, the sum of the size (e.g., length) of the side of the fan-out region 103 close to the first region 101 and the size of the side of the second region 102 close to the first region 101 along the direction surrounding the first region 101 is less than or equal to the perimeter of the first region 101. It can be understood that the sum of the side lengths of the side of the second region 102 close to the first region 101 and the side of the fan-out region 103 close to the first region 101 is less than the perimeter of the first region 101. In this way, when the display substrate is bonded, it can avoid the overlap between the second region 102 and the fan-out region 103, which helps to improve the flatness of the bonding and is beneficial to improving the display effect.

[0129] In some embodiments, at least a part of the peripheral area 52 is used as a switch button of the display device.

[0131] The embodiment of the present application also provides a manufacturing method for a display device.

[0133] Provide a transparent cover plate, where the transparent cover plate includes a central region and an edge region surrounding the central region, and the angle between the edge region and the plane where the central region is located is greater than 0 degrees;

[0134] Bond the display substrate to the transparent cover plate, where the display substrate is the display substrate described in any one of the above, the first region of the display substrate is bonded to the central region of the transparent cover plate, and the second region of the display substrate is bonded to the edge region of the transparent cover plate.

[0135] During implementation, first manufacture the display substrate 605, and the manufactured display substrate 605 is specifically any one of the display substrates in the above display substrate embodiments.

[0136] The display substrate 605 may include a touch control module. Exemplarily, it may include the above first touch control electrode 115 and second touch control electrode 110.

[0137] As Figure 6 and Figure 7 shown, next, sequentially dispose a polarizer 604 and an optical adhesive layer 603 on the display substrate 605.

[0138] In some embodiments, the display device further includes an ink layer 602. Correspondingly, the manufacturing method for the display device further includes a step of forming the ink layer 602. Generally, the ink layer 602 is coated on a specified area of the transparent cover plate 601, and the ink layer 602 may also be formed on the display substrate 605.

[0139] As Figure 8 shown, bond the transparent cover plate 601 to the display substrate 605. As Figure 9 shown, finally, bond the SCF 606 on the side of the display substrate 605 away from the transparent cover plate 601.

[0140] In some embodiments, the display device further includes an ink layer 602. As Figure 5B and Figure 5C shown, the ink layer 602 includes a first part 6021, a second part 6022, and a third part 6023.

[0141] Please refer to Figures 11 to 13 As shown, the first part is disposed around the peripheral area 52, and the first part can be understood as the outermost part of the peripheral area 52.

[0142] The second part is located between the main display area 51 and the peripheral area 52, and the second part is disposed around the main display area 51. It can be understood that the part within the second part is the light-emitting area of the main display area 51.

[0143] The third part is located between the first part and the second part, and the third part is in communication with both the first part and the second part. Along the direction of surrounding the main display area 51, the third part and the peripheral area 52 are arranged in sequence.

[0144] In this embodiment, the third part of the ink layer 602 corresponds to the part outside the second area 102 in the fan-out area 103. Exemplarily, it may include the fan-out area 103 or the first connection part 104.

In this way, the touch function can be independently realized through the second touch electrode 110 in the second area 102 and used as a control button, and the setting of physical buttons can be correspondingly reduced, which helps to improve the user experience.
