[0050] The features and exemplary embodiments of various aspects of the present application will be described in detail below. To make the objectives, technical solutions, and advantages of the present application clearer and more understandable, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by showing examples of the present application.

[0051] It should be noted that in this text, relative terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprising", "including" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, the elements defined by the statement "comprising..." do not exclude the existence of additional identical elements in the process, method, article or device comprising the said elements.

[0052] With the progress of society, people's requirements for display devices have also increased, and how to achieve a higher screen-to-body ratio has become a difficult problem that needs to be solved urgently. In existing display devices, there are corners between adjacent borders. In order to improve the feel of use, some display devices will set the corners as arc-shaped corners.

[0053] There is usually a large area near the corners of the display device that cannot be displayed. The applicant found through research that this is because more electronic devices and signal traces usually need to be arranged at the corners, so it will occupy a relatively large area near the corners and it is difficult to meet the needs of narrow borders.

[0054] To solve the above problems, please refer to Figure 1 and Figure 2 , an embodiment of the present application provides an array substrate 8, which includes a display area A and a wiring area B arranged along the first direction X. The wiring area B includes a straight edge area B1 and a corner area B2 located on at least one side of the straight edge area B1 in the second direction Y. The display area A includes a first display area A1 located on one side of the corner area B2 in the first direction X, and the first direction X intersects the second direction Y.

[0055] The array substrate 8 includes a plurality of signal lines 1 arranged in the display area A along the second direction Y, and a multiplexing unit 2 arranged in the wiring area B and electrically connected to the signal lines 1. Among them, at least part of the signal lines 1 in the first display area A1 are electrically connected to the multiplexing unit 2 in the straight edge area B1.

[0056] A display device usually includes a display area for realizing a display effect and a non-display area for arranging electronic devices and peripheral traces. The non-display area is usually arranged around the outer periphery of the display area. Among them, the display area A of the array substrate 8 mentioned in the embodiment of the present application corresponds to the display area of the display device, and the wiring area B of the array substrate 8 corresponds to a part of the non-display area of the display device.

[0057] The wiring area B is arranged on one side of the display area A along the first direction X. In the wiring area B, the array substrate 8 is provided with various electronic devices including a multi-way distribution unit 2 and multiple driving traces. The multi-way distributor is used to divide one input signal into multiple outputs. Its input end is connected to the data signal input end, and the output ends are respectively electrically connected to multiple signal lines 1.

[0058] The wiring area B includes a straight-edge area B1 and a corner area B2 located on at least one side of the straight-edge area B1 along the second direction Y. Exemplarily, the first direction X is perpendicular to the second direction Y. For the rectangular array substrate 8, the first direction X and the second direction Y respectively correspond to the long-side direction and the short-side direction of the array substrate 8.

[0059] In some alternative embodiments, there are two corner areas B2, and they are located on both sides of the straight-edge area B1 along the second direction Y. The corner areas B2 of the array substrate 8 correspond to the corner positions of the display device. It should be noted that the outer contour of the corner area B2 in the embodiments of the present application can be a right-angle side, an arc angle side, or other shapes, and the embodiments of the present application do not limit this.

[0060] In the display area A of the array substrate 8, usually multiple pixel electrodes 3 and multiple signal lines 1 are arranged. In the display panel, the pixel electrodes 3 are used to drive the corresponding light-emitting units to achieve a light-emitting effect, thereby presenting a corresponding display screen. The multiple signal lines 1 are electrically connected to the pixel electrodes 3 and are used to transmit driving signals to the pixel electrodes 3. Optionally, the signal lines 1 are data lines. A single signal line 1 extends along the first direction X and is connected to multiple pixel electrodes 3 to simultaneously transmit data signals to multiple pixel electrodes 3 in the same column. At the same time, multiple columns of pixel electrodes 3 can be provided with data signals at different times through a multi-way distributor unit respectively, so as to meet the requirements of data driving.

[0061] The display area A includes a first display area A1 located on one side of the corner area B2 along the first direction X. Usually, the signal lines 1 located in the first display area A1 are controlled by the multi-way distribution unit 2 located in the corner area B2. However, in the embodiments of the present application, in order to reduce the size of the corner area B2, at least some of the signal lines 1 in the first display area A1 are electrically connected to the multi-way distribution unit 2 located in the straight-edge area B1, that is, some of the multi-way distribution units 2 located in the corner area B2 are transferred to the straight-edge area B1, so that the number of multi-way distribution units 2 in the straight-edge area B1 increases, and the number of multi-way distribution units 2 in the corner area B2 decreases. Thus, the area ratio of the corner area B2 can be reduced, and further the displayable area near the corner of the display device can be increased, the screen-to-body ratio can be improved, and the purpose of a narrow border can be achieved.

[0062] In some embodiments, as Figure 1 and Figure 2 shown, all the multi-way distribution units 2 are located in the straight-edge area B1.

[0063] Based on the above embodiments, in the embodiments of the present application, all the multi-way distribution units 2 are arranged within the straight-edge area B1, such that there are no multi-way distribution units 2 within the corner area B2, thereby further reducing the area ratio of the corner area B2 and increasing the screen ratio of the display device.

[0064] In some embodiments, the straight-edge area B1 includes a first area B11 and a second area B12 located on at least one side of the first area B11 in the second direction Y. A plurality of multi-way distribution units 2 within the first area B11 are uniformly arranged at intervals of a first preset distance L1 in the second direction Y, and a plurality of multi-way distribution units 2 within the second area B12 are uniformly arranged at intervals of a second preset distance L2 in the second direction Y. Among them, the first preset distance L1 is greater than the second preset distance L2.

[0065] The number of the second areas B12 is the same as that of the corner areas B2, and the second areas B12 are arranged between the corresponding corner areas B2 and the first area B11. Multi-way distribution units 2 are provided in both the first area B11 and the second area B12. The multi-way distribution units 2 within the first area B11 are used to control the signal lines 1 within the display area A corresponding to the first area B11, while the multi-way distribution units 2 within the second area B12 are used to control the signal lines 1 within the first display area A1 in addition to controlling the signal lines 1 within the display area A corresponding to the second area B12.

[0066] The first preset distance L1 being greater than the second preset distance L2 means that the density of the multi-way distribution units 2 within the second area B12 is greater than that of the multi-way distribution units 2 within the first area B11. In the embodiments of the present application, by increasing the number of the multi-way distribution units 2 within the second area B12, it can control the signal lines 1 within the first display area A1, thereby reducing the area size of the corner area B2. Optionally, the size of the second area B12 in the second direction Y is the same as the size of the corner area B2 in the second direction Y, and the first preset distance L1 is twice the second preset distance L2.

[0067] In the embodiments of the present application, only the multi-way distribution units 2 within the second area B12 are changed, without changing the multi-way distribution units 2 within the first area B11. This design can reduce the modification of the device layout in the array substrate 8 and reduce the structural modification of the traces connected to the multi-way distribution units 2.

[0068] In some embodiments, please refer to Figure 1 and Figure 2 , the array substrate 8 further includes a first connection line 4 connecting the signal lines 1 within the first display area A1 and the multi-way distribution units 2. The first connection line 4 is used to connect the multi-way distribution units 2 and the signal lines 1 within the first display area A1.

[0069] In some embodiments, at least a part of the first connection line 4 is connected to the multi-way distribution unit 2 in the corner area B2 and the straight-edge area B1.

[0070] In the embodiments of the present application, since at least a part of the multi-way distribution units 2 corresponding to the signal lines 1 in the first display area A1 are located in the straight-edge area B1, at least a part of the first connection line 4 for connecting the two will extend in the straight-edge area B1. Therefore, the space size occupied by the first connection line 4 in the corner area B2 can be reduced to a certain extent, thereby further improving the narrow border effect.

[0071] In some embodiments, please refer to Figure 3 and Figure 4 , the display area A includes a second display area A2 located on one side of the straight-edge area B1 in the first direction X, and the wiring density of the second display area A2 is greater than that of the first display area A1; at least a part of the first connection line 4 passes through the second display area A2 and is connected to the signal line 1 in the first display area A1.

[0072] The first display area A1 corresponds to the corner area B2, and the second display area A2 corresponds to the straight-edge area B1. The first connection line 4 is used to connect the multi-way distribution unit 2 and the signal line 1 in the first display area A1. Generally, the first connection line 4 needs to enter the first display area A1 through the corner area B2. In the embodiments of the present application, first, a part of the multi-way distribution units 2 that should be located in the corner area B2 are arranged in the straight-edge area B1, and then, on this basis, at least a part of the first connection line 4 passes through the second display area A2 and is connected to the signal line 1 in the first display area A1, thereby increasing the wiring density of the second display area A2.

[0073] This design can reduce the number of routing lines in the corner area B2, thereby further reducing the size of the corner area B2, improving the screen-to-body ratio of the display device, and achieving the purpose of a narrower border. Optionally, all the first connection lines 4 pass through the second display area A2 and are connected to the signal line 1 in the first display area A1.

[0074] It should be noted that the embodiments of the present application do not limit the structure of the first connection line 4. Exemplarily, the first connection line 4 can be a straight line, a curve, a broken line, or other line structures.

[0075] In some embodiments, as Figure 4 shown, the first connection line 4 includes a first segment 41 extending along the first direction X and a second segment 42 extending along the second direction Y, and the second segment 42 is connected to the first segment 41.

[0076] As can be seen from the foregoing, the first connection line 4 is connected to the signal line 1 in the first display area A1 through the second display area A2, and a plurality of pixel electrodes 3 are arranged in the second display area A2. In order to avoid the pixel electrodes 3 in the second display area A2, the embodiment of the present application makes the first connection line 4 include a first section 41 and a second section 42 extending in different directions to meet the routing layout requirements.

[0077] In some embodiments, as Figure 4 shown, the number of the first sections 41 and the second sections 42 is multiple, and the multiple first sections 41 and the multiple second sections are alternately connected to form a routing manner similar to a stepped shape, so as to be able to avoid a plurality of pixel electrodes 3.

[0078] In some embodiments, the array substrate 8 includes a plurality of pixel electrodes 3 arranged in an array along the first direction X and the second direction Y, and at least a part of the second sections 42 in the first display area A1 are located between adjacent pixel electrodes 3 in the first direction X and are connected to the signal line 1.

[0079] In the conventional array substrate 8, the connection line for connecting the demultiplexing unit 2 and the signal line 1 is usually connected to one end point of the signal line 1 in the extending direction. In this connection manner, the connection line has to pass through the corner area B2 to be connected to the signal line 1.

[0080] In the embodiment of the present application, at least a part of the second ends in the first display area A1 are located between adjacent pixel electrodes 3 in the first direction X and are connected to the signal line 1, and a single signal line 1 usually needs to be connected to all the pixel electrodes 3 in the first direction X. Therefore, the connection end of the first connection line 4 and the signal line 1 in the first display area A1 is not located at one end of the signal line 1 in the extending direction, but at other positions on the signal line 1 except the end points.

[0081] This design makes it not necessarily required for the first connection line 4 to extend into the first display area A1 through the corner area B2, so that more first connection lines 4 can be located outside the corner area B2, further reducing the size of the corner area B2, thereby improving the screen occupation ratio of the display device and achieving the purpose of a narrower border.

[0082] In some embodiments, at least a part of the first sections 41 are located between adjacent pixel electrodes 3 in the second direction Y. A part of the first sections 41 led out from the straight edge area B1 extends into the second display area A2. In order to avoid the pixel electrodes 3 in the second display area A2, at least a part of the first sections 41 are located between adjacent pixel electrodes 3 in the second direction Y. Optionally, all the first sections 41 are located between adjacent pixel electrodes 3 in the second direction Y.

[0083] In some embodiments, please refer to Figure 5 and Figure 6, the number of the first segment 41 and the second segment 42 is one each. The first segment 41 is connected to the demultiplexing unit 2, and the second segment 42 is connected to the signal line 1. The first segment 41 and the second segment 42 are connected to each other. The first segment 41 is used to receive the signal output by the demultiplexing unit 2, and the second segment 42 is used to transmit the signal of the first segment 41 to the corresponding signal line 1.

[0084] In the embodiment of the present application, one first segment 41 and one second segment 42 are provided, thereby reducing the complexity of the wiring in the array substrate 8, reducing the risk of signal crosstalk between different wirings, and improving the reliability.

[0085] In some embodiments, the connection ends of the plurality of first connection lines 4 on the demultiplexing unit 2 are arranged in sequence in the second direction Y along with the corresponding signal lines 1.

[0086] The plurality of first connection lines 4 can be connected to the same demultiplexing unit 2 or to different demultiplexing units 2. The embodiment of the present application does not limit this. Each first connection line 4 is provided with a connection end on the demultiplexing unit 2. Generally, the signal output by the driving chip 6 is transmitted to the demultiplexing unit 2 and is transmitted to the corresponding signal line 1 through the electrical connection between the connection end and the first connection line 4.

[0087] In the embodiment of the present application, the connection ends of the first connection lines 4 on the demultiplexing unit 2 are arranged in sequence in the second direction Y along with the corresponding signal lines 1, so that the signal order transmitted by the driving chip 6 to the demultiplexing unit 2 is the same as the order of the signal lines 1, thereby eliminating the need to additionally adjust the signals transmitted by the driving chip 6.

[0088] In some embodiments, such as Figure 5 and Figure 6 shown, the sorting of the plurality of signal lines 1 located in the first display area A1 and connected to different demultiplexing units 2 in the second direction Y is the same as the sorting of the corresponding demultiplexing units 2 in the second direction Y.

[0089] It should be noted that the "corresponding demultiplexing unit 2" mentioned in the embodiment of the present application refers to the demultiplexing unit 2 electrically connected to the signal line 1. At the same time, the "sorting of the plurality of signal lines 1 in the second direction Y" and the "sorting of the demultiplexing units 2 in the second direction Y" mentioned in the embodiment of the present application refer to the sorting of the signal lines 1 and the corresponding demultiplexing units 2 in the same direction. Exemplarily, the sorting mentioned in the embodiment of the present application refers to the arrangement order from the first display area A1 to the second display area A2.

[0090] In the embodiment of the present application, part of the multi-way distribution unit 2 is transferred from the corner area B2 to the straight-edge area B1, while the corresponding relationship between the multi-way distribution unit 2 and the signal line 1 remains unchanged, so that the arrangement order of the signal lines 1 in the first display area A1 is the same as the arrangement order of the corresponding multi-way distribution unit 2. Therefore, it is not necessary to adjust the signal order at the input end of each multi-way distribution unit 2, and further, it is not necessary to adjust and change the output signal of the driving chip 6, reducing the risk of signal transmission errors.

[0091] In some embodiments, as Figure 5 and Figure 6 shown, the sorting of multiple signal lines 1 connected to the same multi-way distribution unit 2 in the second direction Y is the same as the sorting of the corresponding first connection line 4 in the second direction Y.

[0092] It should be noted that the "sorting of the first connection line 4 in the second direction Y" mentioned in the embodiment of the present application refers to: the arrangement order of the connection ends of multiple first connection lines 4 and the corresponding multi-way distribution unit 2 in the second direction Y, or it can also be the arrangement order of the corresponding first section 41 of multiple first connection lines 4 in the second direction Y.

[0093] On the basis of the foregoing embodiment, the embodiment of the present application does not adjust the arrangement order of the output ends of the same multi-way distribution unit 2, so that the sorting of all the signal lines 1 in the second direction Y is the same as the sorting of the corresponding output ends on the multi-way distribution unit 2, thereby improving the reliability of signal transmission.

[0094] In some embodiments, the first connection line 4 and at least part of the signal lines 1 are located on different layers to reduce the risk of signal crosstalk.

[0095] As can be seen from the foregoing content, at least part of the first connection line 4 needs to extend through the second display area A2 into the first display area A1 to be connected to the corresponding signal line 1. Due to this wiring layout form, the first connection line 4 will overlap with at least part of the signal lines 1. In order to reduce the risk of signal crosstalk, therefore, in the embodiment of the present application, the first connection line 4 and at least part of the signal lines 1 are located on different layers, thereby reducing the risk of signal crosstalk.

[0096] In some embodiments, the array substrate 8 further includes a second connection line 5 for connecting the signal lines 1 and the multi-way distribution unit 2 located in the second display area A2. The signal lines 1 located in the second display area A2 are arranged on the same layer as the second connection line 5 and are located on different layers from the first connection line 4.

[0097] The second connection line 5 is used to connect the signal line 1 in the second display area A2 and the multi-way distribution unit 2. Since the first connection line 4 will occupy a part of the area of the second display area A2, some signal lines 1 in the second display area A2 and the first connection line 4 will overlap in the thickness direction of the array substrate 8.

[0098] In order to reduce the influence of the first connection line 4 on the signal line 1 in the second display area A2, the embodiment of the present application makes the first connection line 4 and the signal line 1 in the second display area A2 located in different layers. At the same time, in order to ensure the mutual connection between the second connection line 5 and the signal line 1 in the second display area A2, the embodiment of the present application also makes the signal line 1 located in the second display area A2 and the second connection line 5 located in the same layer, so as to make the wiring layout clear and reliable.

[0099] In some embodiments, please refer to Figure 7 , the array substrate 8 further includes a driving chip 6 and a third connection line that electrically connects the driving chip 6 and the multi-way distribution unit 2. Among them, a plurality of multi-way distribution units 2 are electrically connected to the driving chip 6 through the same third connection line.

[0100] One end of the third connection line is connected to the input end of the multi-way distribution unit 2, and is used to transmit the signal sent by the driving chip 6 to the corresponding multi-way distributor. Among them, the third connection line is electrically connected to the driving chip 6. The third connection line and the driving chip 6 can be directly connected or indirectly connected through other conductive structures. The embodiment of the present application does not limit this.

[0101] A single third connection line includes a plurality of branches so as to be able to connect a plurality of multi-way distribution units 2. Optionally, one third connection line can connect two to six multi-way distribution units 2.
