Description

Technical Field

[0002] With the continuous advancement of display module technology, small-sized panels are gradually evolving towards thinner and lighter designs, higher screen-to-body ratios, ultra-narrow bezels, and even borderless designs. Traditional display panels typically consist of a display area and a non-display area surrounding the display area. The non-display area is used to arrange and bond flexible circuits, and the presence of these flexible circuits occupies a significant amount of non-display space, which is detrimental to narrow bezel designs.

[0003] Therefore, there is an urgent need for a new display panel and display device. Summary of the Invention

[0047] In the display panel provided in this application embodiment, the display panel includes a display area, a non-display area, and register units.

[0062] The features and exemplary embodiments of various aspects of this application will now be described in detail. Numerous specific details are set forth in the following detailed description to provide a comprehensive understanding of this application. However, it will be apparent to those skilled in the art that this application can be implemented without requiring some of these specific details. The following description of embodiments is merely intended to provide a better understanding of this application by illustrating examples. In the accompanying drawings and the following description, at least some well-known structures and techniques are not shown to avoid unnecessarily obscuring the application; and, for clarity, the dimensions of some structures may be exaggerated. Furthermore, the features, structures, or characteristics described below can be combined in any suitable manner in one or more embodiments.

[0064] The directional terms appearing in the following description refer to the directions shown in the figures and are not intended to limit the specific structure of the embodiments of this application.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0065] As customer demands continue to rise and screen ratios increase, and given the inability to change the display area, reducing bezels is becoming increasingly popular among mobile phone manufacturers. Compared to a linear non-display area extending in a certain direction, the irregularly shaped non-display area located at one end of the linear non-display area is more irregular in shape. Furthermore, irregularly shaped non-display areas generally have a wider width due to the more complex and numerous connections between register units and signal lines within the display area. Therefore, reducing the width of irregularly shaped non-display areas is particularly important.

[0066] To address the aforementioned technical problems, this application is proposed. For a better understanding of this application, the following is combined with... Figures 1 to 7 The display panel and display device according to the embodiments of this application will be described in detail.

[0067] like Figure 1 and Figure 2As shown, an embodiment of the first aspect of this application provides a display panel, the display panel including: a display area 100 including a first edge 110 extending along a first direction Y, and at least one first irregular edge 120 connected to one end of the first edge 110 and extending along an arc path; a non-display area 200 including a first non-display area 210 and an irregular non-display area 220, the first non-display area being disposed on the side of the first edge 110 away from the display area 100, and the irregular non-display area 220 being disposed on the side of the first irregular edge 120 away from the display area 100; a register unit 300 including a first register unit 310 disposed in the first non-display area 210 and a second register unit 320 disposed in the irregular non-display area 220, wherein the extension dimension of the first register unit 310 in the direction away from the display area 100 is greater than its extension dimension in the first direction Y, and the extension dimension of the second register unit 320 in the direction away from the display area 100 is smaller than its extension dimension in the reference direction P, the reference direction P being parallel to the tangent of the first irregular edge 120.

[0068] Optionally, at different positions in the non-display area 220 of the irregular shape, corresponding to different positions of the first irregular edge 120, the tangent extension direction of the first irregular edge 120 is different, so the reference direction P is different at different positions, and the second register unit 320 at different positions can correspond to different reference directions P.

[0069] In the display panel provided in this embodiment, the display panel includes a display area 100, a non-display area 200, and a register unit 300. The display area 100 may be provided with a pixel driving circuit 170 for driving the light-emitting unit to emit light. The display area 100 includes a first edge 110 and a first irregular edge 120. The first edge 110 extends in a straight line along a first direction Y, and the first irregular edge 120 extends in an irregular shape along an arc path, which can enrich the shape of the display area 100. The non-display area 200 is disposed around the display area 100. The non-display area 200 includes a first non-display area 210 disposed on one side of the first edge 110 and an irregular non-display area 220 disposed on one side of the first irregular edge 120. The register unit 300 includes a first register unit 310 disposed in the first non-display area 210 and a second register unit 320 disposed in the irregular non-display area 220. The extension dimension of the first register unit 310 in the direction away from the display area 100 is greater than its extension dimension in the first direction Y, and the extension dimension of the second register unit 320 in the direction away from the display area 100 is smaller than its extension dimension in the reference direction P. That is, the shapes of the first register unit 310 and the second register unit 320 are different, and the extension dimension of the second register unit 320 in the reference direction P is longer and the extension dimension of the second register unit 320 in the direction away from the display area 100 is smaller. This can reduce the width of the irregular non-display area 220 and thus solve the problem of the display panel bezel being too wide.

[0070] Optional, such as Figure 3 As shown, a pixel driving circuit 170 can be disposed within the display area 100. The pixel driving circuit 170 is used to drive the light-emitting units of the display panel to emit light. Optionally, signal lines can also be disposed within the display area 100. The signal lines may include, for example, power supply voltage signal lines, data signal lines 161, scan signal lines 162, light emission control signal lines 163, reference voltage signal lines, etc. Multiple light-emitting units are arranged in an array along the first direction Y and the second direction X, and the corresponding multiple pixel driving circuits 170 are arranged in an array along the first direction Y and the second direction X.

[0071] Optionally, the display area 100 is provided with a plurality of pixel driving circuits 170 arrayed along a first direction Y and a second direction X, and a plurality of data signal lines 161, light emission control signal lines 163, and scan signal lines 162 distributed horizontally and vertically. The plurality of pixel driving circuits 170 are all connected to the data signal lines 161, light emission control signal lines 163, and scan signal lines 162. The data signal lines 161 extend along the first direction Y, while the light emission control signal lines 163 and scan signal lines 162 extend along the second direction X. The first direction Y and the second direction X intersect, for example, the first direction Y and the second direction X are perpendicular. One light emission control signal line 163 and one scan signal line 162 form a group located between two adjacent rows of pixel driving circuits 170. That is, pixel driving circuits 170 arranged in a row along the second direction X can be connected to the same group of light emission control signal lines 163 and scan signal lines 162; that is, pixel driving circuits 170 in the same row have a corresponding group of light emission control signal lines 163 and scan signal lines 162. This allows each pixel driving circuit 170 to be connected to the data signal line 161, the light emission control signal line 163, and the scan signal line 162 along the shortest path. The register unit 300 is disposed on at least one side of the display area 100 in the second direction X, so that the scan signal line 162 and the light emission control signal line 163 can be connected to the register unit 300 at least one end in the second direction X.

[0072] Optionally, the display area 100 includes a first display area 140 and a second display area 150. The first display area 140 is located on one side of the first edge 110, and the second display area 150 is located on one side of the first irregular edge 120. For example, when the two first edges 110 are respectively disposed on both sides of the display area 100 in the second direction X, and the two first irregular edges 120 are respectively disposed on both sides of the display area 100 in the second direction X, the first display area 140 can be located between the two oppositely disposed first edges 110, and the second display area 150 can be located between the two oppositely disposed first irregular edges 120. The number of second display areas 150 can be two, and the two second display areas 150 are respectively disposed on both sides of the first display area 140 in the first direction Y.

[0073] Optionally, the scan signal line 162 and the light emission control signal line 163 in the first display area 140 can be connected to the first register unit 310, and the scan signal line 162 and the light emission control signal line 163 in the second display area 150 can be connected to the second register unit 320.

[0074] In some optional embodiments, the number of first non-display areas 210 is at least two, the two first non-display areas 210 are respectively disposed on both sides of the display area 100, and at least one first non-display area 210 is provided with an irregular non-display area 220 at one end in the first direction Y.

[0075] In these optional embodiments, by providing two first non-display areas 210 on both sides of the display area 100, and by providing a first register unit 310 in each first non-display area 210, the scanning signal line 162 and the light emission control signal line 163 can be driven at both ends, which can improve the problem of uneven display caused by inconsistent voltage drop at different positions of the display area 100 and improve the display effect of the display panel.

[0076] Optionally, the non-display area 200 further includes a second non-display area 230, which extends along the second direction X and is located on at least one side of the display area 100 in the first direction Y. The irregular non-display area 220 is connected between the first non-display area 210 and the second non-display area 230.

[0077] In these optional embodiments, the non-display area 200 also includes a second non-display area 230. The second non-display area 230 and the first non-display area 210 are located on different sides of the display area 100 in different directions. The first non-display area 210 and the second non-display area 230 can be connected by the irregularly shaped non-display area 220, making the non-display area 200 more continuous and improving the display effect of the display panel.

[0078] Optionally, two first non-display areas 210 and two second non-display areas 230 are alternately arranged around the display area 100, and each of the first non-display areas 210 and the second non-display areas 230 is connected by an irregularly shaped non-display area 220. This makes the non-display areas 200 more continuous and can improve the display effect of the display panel.

[0079] The extension dimension of the first register unit 310 in the direction away from the display area 100 can be the extension dimension of the first register unit 310 in the second direction X. In this embodiment, the dimension of the first register unit 310 in the first direction Y is smaller than its extension dimension in the second direction X, so that more first register units 310 arranged side by side along the first direction Y can be set in the first non-display area 210. Each first register unit 310 is used to electrically connect to the pixel driving circuit 170 of each row.

[0080] The extension dimension of the second register in the direction away from the display area 100 refers to the extension dimension of the second register in the direction from the display area 100 to the irregular non-display area 220. The direction from the display area 100 to the irregular non-display area 220 can be perpendicular to the tangent of the first irregular edge 120.

[0081] Optionally, the distribution areas of the first register unit 310 and the second register unit 320 can be the same or different. For example, the distribution areas of the first register unit 310 and the second register unit 320 can be the same. In this embodiment, the shape of the second register unit 320 is changed relative to the first register unit 310 without changing the area of ​​the second register unit 320, so that the shape of the second register unit 320 can better fit the irregular non-display area 220, reducing the width of the irregular non-display area 220, that is, reducing the extension dimension of the irregular non-display area 220 in the direction from the display area 100 to the irregular non-display area 220.

[0082] In some optional embodiments, multiple second register units 320 in the irregular non-display area 220 are arranged adjacently. That is, no redundant register units 400 are provided in the irregular non-display area 220, and there are no redundant register units 400 in the irregular display area 100, thereby providing sufficient space for the second register units 320, ensuring that the second register units 320 have sufficient size and guaranteeing the display effect.

[0083] Optionally, the spacing between adjacent second register units 320 is smaller than the extension dimension of the second register unit 320 in the reference direction P. That is, the distance between two adjacent second register units 320 can be set to be smaller, so as to appropriately increase the area of ​​the second register unit 320 at the edge.

[0084] In some alternative embodiments, the display panel further includes a second redundant register unit 420 located in the irregular non-display area 220, and a plurality of second register units 320 are arranged between adjacent second redundant register units 420.

[0085] In these optional embodiments, the irregularly shaped non-display area 220 is provided with a second redundant register unit 420, which can improve the display unevenness problem caused by the uneven distribution of metal material within the irregularly shaped non-display area 220. Furthermore, multiple second register units 320 are provided between two adjacent second redundant register units 420, meaning the number of second redundant register units 420 is less than the number of second register units 320. By reducing the number of second redundant register units 420, sufficient space can be left for the placement of second register units 320. For example, two, three, four, or five second register units 320 can be provided between adjacent second redundant register units 420.

[0086] Optionally, the density of the second redundant register unit 420 gradually decreases along the arc path extending from the first irregular edge 120 and towards the direction close to the first non-display area 210. That is, the distribution density of the second redundant register unit 420 is different in different areas of the irregular non-display area 220, which facilitates adjusting the distribution of the second register unit 320 according to the shape of the irregular non-display area 220, making the distribution of the second register unit 320 more reasonable.

[0087] Optionally, the display area 100 is provided with multiple pixel driving circuits 170. A first register unit 310 is connected to the pixel driving circuit 170; a second register unit 320 is connected to the pixel driving circuit 170; and a second redundant register unit 420 is isolated from the pixel driving circuit 170. The second redundant register unit 420 is not electrically connected to the pixel driving circuit 170. Optionally, referring to the above, the first register unit 310 and the second register unit 320 can be used to connect pixel driving circuits 170 in different rows. The second redundant register unit 420 is used to make the metal material distribution area of ​​the irregular non-display area 220 more uniform, and is not used to transmit control signals to the pixel driving circuit 170. Therefore, the second redundant register unit 420 and the pixel driving circuit 170 can be isolated from each other to simplify the circuit structure of the display panel. The output terminal of the second redundant register unit 420 is left floating and does not output signals to the pixel driving circuit 170.

[0088] In some alternative embodiments, such as Figure 1 and Figure 4 As shown, the display panel also includes a redundant register unit 400, at least one of which is located in the first non-display area 210.

[0089] In these optional embodiments, the display panel further includes at least one redundant register unit 400 in the first non-display area 210. The redundant register unit 400 may not be electrically connected to the signal lines within the display area 100. The redundant register unit 400 is used to improve the display uniformity problem caused by uneven wire distribution within the first non-display area 210. For example, the redundant register unit 400 is isolated from the pixel driving circuit 170. The redundant register unit 400 is not electrically connected to the pixel driving circuit 170. The output terminal of the redundant register unit 400 is left floating and does not output signals to the pixel driving circuit 170.

[0090] There are various ways to configure the redundant register unit 400. For example, the circuit structure of the redundant register unit 400 and the circuit structure of the first register unit 310 can be the same. For example, the first register unit 310 includes transistors and capacitors, and the redundant register unit 400 also includes transistors and capacitors, so that the redundant register unit 400 and the first register unit 310 can be fabricated in the same process steps, which can simplify the manufacturing process of the display panel.

[0091] Optional, such as Figure 4 As shown, the redundant register unit 400 may exist only in the first non-display area 210, and the redundant register unit 400 may not be provided in the irregular non-display area 220, so as to further reduce the size of the irregular non-display area 220.

[0092] In some other alternative embodiments, such as Figure 1 and Figure 5 As shown, the display panel also includes a redundant register unit 400. The redundant register unit 400 includes a first redundant register unit 410 located in the first non-display area 210 and a second redundant register unit 420 located in the irregular non-display area 220. The density of the first redundant register unit 410 in the first non-display area 210 per unit area is less than the density of the second redundant register unit 420 in the irregular non-display area 220.

[0093] In these optional embodiments, the redundant register unit 400 includes a first redundant register unit 410 located in the first non-display area 210 and a second redundant register unit 420 located in the irregular non-display area 220. That is, redundant register units 400 are provided in both the first non-display area 210 and the irregular non-display area 200. However, the density of the first redundant register unit 410 in the first non-display area 210 per unit area is less than the density of the second redundant register unit 420 in the irregular non-display area 220, so as to reduce the size of the irregular non-display area 220.

[0094] There are several ways to set the density of the first redundant register unit 410 in the first non-display area 210 per unit area to be less than the density of the second redundant register unit 420 in the irregular non-display area 220. For example, the number of the first redundant register unit 410 in the first non-display area 210 per unit area is less than the number of the second redundant register unit 420 in the irregular non-display area 220.

[0095] In these optional embodiments, the size of the irregular non-display area 220 can be reduced by decreasing the number of second redundant register units 420 within the irregular non-display area 220. Optionally, in these optional embodiments, the distribution area of ​​the first redundant register unit 410 and the distribution area of ​​the second redundant register unit 420 can be the same, and / or, the shape of the first redundant register unit 410 and the shape of the second redundant register unit 420 can be the same.

[0096] Optionally, the first redundant register unit 410 and the first register unit 310 are arranged alternately along the first direction Y in the first non-display area 210 to improve the display unevenness problem caused by the uneven distribution of metal material at different positions in the first non-display area 210.

[0097] In some alternative embodiments, the area percentage of the first redundant register unit 410 in the first non-display area 210 is smaller than the area percentage of the second redundant register unit 420 in the irregular non-display area 220.

[0098] In these alternative embodiments, by reducing the area ratio of the second redundant register unit 420 within the irregular non-display area 220, the size of the irregular non-display area 220 can be reduced as much as possible, and the border size of the irregular non-display area 220 can be reduced.

[0099] In some alternative embodiments, the extension dimension of the second redundant register unit 420 in the direction away from the display area 100 is smaller than its extension dimension in the reference direction P.

[0100] In these optional embodiments, by reasonably setting the size of the second redundant register unit 420, the extension size of the second redundant register unit 420 in the width direction of the irregular non-display area 220 can be reduced, which is beneficial to reducing the size of the irregular non-display area 220 and reducing its width. The width direction of the irregular non-display area 220 can be the direction from the display area 100 to the irregular non-display area 220, or it can be a direction perpendicular to the tangent of the first irregular edge 120.

[0101] For example, the first redundant register unit 410 is isolated from the pixel driving circuit 170. The first redundant register unit 410 is not electrically connected to the pixel driving circuit 170. The output terminal of the first redundant register unit 410 is left floating and does not output a signal to the pixel driving circuit 170.

[0102] In some alternative embodiments, such as Figures 1 to 5 As shown, the first register unit 310 includes a first gate register 311 and a first light emission control register, which are arranged side by side along a direction away from the display area 100.

[0103] In these alternative embodiments, the first gate register 311 and the first light emission control register of the first register unit 310 are arranged side by side in a direction away from the display area 100, which makes the extension dimension of the first register unit 310 in the direction away from the display area 100 greater than its extension dimension in the first direction Y, thereby facilitating the arrangement of more first register units 310 in the first non-display area 210.

[0104] For example, the output terminals of the first gate register 311 and the first light emission control register 312, which are connected to the same pixel driving circuit 170, are connected to the gates of different transistors in the same pixel driving circuit 170.

[0105] Optionally, the dimensions and shapes of the first gate register 311 and the first light-emitting control register 312 can be the same or different. For example, the extension dimension of the first gate register 311 in the first direction Y and the extension dimension of the first light-emitting control register 312 in the first direction Y are the same. This is beneficial because it makes the extension dimension of the first register unit 310 in the first direction Y the same at different positions, making the shape of the first register unit 310 more regular and easier to arrange. The extension dimension of the first gate register 311 in the second direction X and the extension dimension of the second light-emitting control register 312 in the second direction X can be the same or different.

[0106] In some alternative embodiments, such as Figures 1 to 5 As shown, the second register unit 320 includes a second gate register 321 and a second light emission control register 322, which are arranged side by side along the reference direction P.

[0107] For example, the output terminal of the second gate register 321 and the output terminal of the second light emission control register 322, which are connected to the same pixel driving circuit 170, are connected to the gates of different transistors in the same pixel driving circuit 170.

[0108] In these optional embodiments, the second gate register 321 and the second light emission control register 322 of the second register unit 320 are arranged side by side along the reference direction P. This is advantageous because the extension dimension of the second register unit 320 in the direction away from the display area 100 is smaller than its extension dimension in the reference direction P. It also facilitates the direct electrical connection of the second gate register 321 and the second light emission control register 322 to the scan signal line 162 and the light emission control signal line 163 in the display area 100. This simplifies the arrangement of the signal lines and helps to further reduce the width dimension of the irregular non-display area 220.

[0109] Alternatively, in some other alternative embodiments, such as Figure 1 and Figure 6 As shown, the second gate register 321 and the second light emission control register 322 are arranged side by side in a direction away from the display area 100, and at least one of the second gate register 321 and the second light emission control register 322 has an extension dimension in the direction away from the display area 100 that is smaller than its extension dimension in the reference direction P.

[0110] In these optional embodiments, the second gate register 321 and the second light-emitting control register 322 of the second register unit 320 are arranged side by side along the direction away from the display area 100, such that the arrangement of the second gate register 321 and the second light-emitting control register 322 in the second register unit 320 is similar to the arrangement of the first gate register 311 and the first light-emitting control register in the first register unit 310, which simplifies the overall fabrication process of the register unit 300. Furthermore, at least one of the second gate register 321 and the second light-emitting control register 322 has a smaller extension dimension in the direction away from the display area 100 than its extension dimension in the reference direction P. This facilitates reducing the width of the irregular non-display area 220.

[0111] In some optional embodiments, when the second gate register 321 and the second light-emitting control register 322 are arranged side by side in a direction away from the display area 100, the extension dimensions of the second gate register 321 and the second light-emitting control register 322 in the direction away from the display area 100 are both smaller than their extension dimensions in the reference direction P. This further facilitates making the extension dimension of the second register unit 320 in the direction away from the display area 100 smaller than its extension dimension in the reference direction P, thereby facilitating the reduction of the width of the irregular non-display area 220.

[0112] In some optional embodiments, there are multiple second register units 320, and the multiple second register units 320 can be distributed sequentially along the extension path of the first irregular edge 120, so that the arrangement of the multiple second registers is more adapted to the shape of the first irregular edge 120.

[0113] In the display panel, the light emission control signal line 163 extends from the display area 100 to the non-display area 200 and is connected to the light emission register in the non-display area 200. Each light emission control signal line 163 is connected to one light emission register. The scan signal line 162 extends from the display area 100 to the non-display area 200 and is connected to the gate register in the non-display area 200. Each scan signal line 162 is connected to one gate register.

[0114] When there are multiple second register units 320, there are multiple second gate registers 321 and multiple second light-emitting control registers 322 within the irregular non-display area 220. In some optional embodiments, the second gate registers 321 and the second light-emitting control registers 322 are arranged side by side along the reference direction P, and multiple second gate registers 321 and multiple second light-emitting registers are alternately distributed along the first irregular edge 120.

[0115] In these optional embodiments, multiple second gate registers 321 and multiple second light-emitting registers are alternately distributed along the irregular edge, allowing adjacent second gate registers 321 and second light-emitting registers to be simultaneously connected to the scan signal line 162 and light-emitting control signal line 163 of the pixel driving circuit 170 in the same row. Figure 4 As shown, the second gate register 321 and the second light-emitting register can be respectively arranged adjacent to the scan signal line 162 and the light-emitting control signal line 163, thereby reducing the distance between each second gate register 321 and each scan signal line 162, and reducing the distance between each second light-emitting register and each light-emitting control signal line 163.

[0116] In some optional embodiments, the first register unit 310 and the second register unit 320 have the same circuit structure. For example, the equivalent circuit diagrams of the first register unit 310 and the second register unit 320 are the same, so that the performance of the first register unit 310 and the second register unit 320 is similar, which can improve the display uniformity of the display panel.

[0117] Register unit 300 typically includes transistors and capacitors. Optionally, the number of transistors in the first register unit 310 and the number of transistors in the second register unit 320 can be the same. For example, in some optional embodiments, the first register unit 310 includes a plurality of first transistors, and the second register unit 320 includes a plurality of second transistors, with the number of first transistors in the first register unit 310 and the number of second transistors in the second register unit 320 being equal. This makes the performance of the first register unit 310 and the second register unit 320 similar, improving the display uniformity of the display panel.

[0118] And / or, the first register unit 310 includes a first capacitor, and the second register unit 320 includes a second capacitor, wherein the number of first capacitors in the first register unit 310 and the number of second capacitors in the second register unit 320 are equal. This makes the performance of the first register unit 310 and the second register unit 320 similar, thereby improving the display uniformity of the display panel.

[0119] Optionally, the size of the first transistor in the first register unit 310 and the corresponding second transistor in the second register unit 320 are equal; and / or, the size of the first capacitor in the first register unit 310 and the corresponding second capacitor in the second register unit 320 are equal, so that the performance of the first register unit 310 and the second register unit 320 is similar, which can improve the display uniformity of the display panel.

[0120] Optionally, the spacing between the plurality of first transistors in the first register unit 310 is less than or equal to the spacing between the corresponding plurality of second transistors in the second register unit 320; and / or, the spacing between at least one first transistor and a first capacitor in the first register unit 310 is less than or equal to the spacing between the corresponding second transistor and a second capacitor in the second register unit 320. This makes the performance of the first register unit 310 and the second register unit 320 similar, thereby improving the display uniformity of the display panel.

[0121] The smaller the spacing between the second transistor and / or the second capacitor in the second register unit 320, the more compact the device distribution, which helps to reduce the bezel width while ensuring the display effect.

[0122] There are various ways to set the shape of the first register unit 310 and the second register unit 320. For example, the shape of the first register unit 310 and the second register unit 320 can both be rectangular, so as to simplify the shape of the first register unit 310 and the second register unit 320 and facilitate the preparation of the first register unit 310 and the second register unit 320.

[0123] In some optional embodiments, the extension dimension of the first register unit 310 in the direction away from the display area 100 is greater than the extension dimension of the second register unit 320 in the direction away from the display area 100; the extension dimension of the first register unit 310 in the first direction Y is smaller than the extension dimension of the second register unit 320 in the reference direction P. By adjusting the shapes of the first register unit 310 and the second register unit 320, the extension dimension of the first register unit 310 in the direction away from the display area 100 is larger, and the extension dimension of the second register unit 320 in the reference direction P is larger, so that the second register unit 320 can be better adapted to the irregular non-display area 220.

[0124] In some optional embodiments, the first register unit 310, arranged side-by-side along the second direction X, is connected to the pixel driving circuit 170. That is, the interconnected first register unit 310 and pixel driving circuit 170 are correspondingly arranged in the second direction X, and the scanning signal line 162 and the light emission control signal line 163 can be connected to the first register unit 310 and pixel driving circuit 170 by extending along the second direction X.

[0125] In some alternative embodiments, in the interconnected second register unit 320 and pixel driving circuit 170, the second register unit 320 is located on the side of the pixel driving circuit 170 away from the first edge 110. That is, in the interconnected second register unit 320 and pixel driving circuit 170, the second register unit 320 is further away from the first display area 140, so as to appropriately increase the extension size of the second register unit 320 in the reference direction P.

[0126] Optionally, the extension dimension of the first register unit 310 in the first direction Y is equal to the extension dimension of the pixel driving circuit 170 in the first direction Y, and / or, the extension dimension of the second register unit 320 in the reference direction P is greater than the extension dimension of the pixel driving circuit 170 in the first direction Y. This is to facilitate adjusting the size of the first register unit 310 according to the shape of the irregular non-display area 220, to appropriately increase the extension dimension of the second register unit 320 in the reference direction P, and to eliminate or reduce redundant register units. For example, the extension dimension of the pixel driving circuit 170 in the first direction Y can be equal to the extension dimension of the display area 100 in the first direction Y divided by the number of rows of the pixel driving circuit 170. The row direction can be parallel to the second direction X.

[0127] In some other alternative embodiments, such as Figure 1 and Figure 7 As shown, the non-display area 220 of the irregular shape has a second irregular shape edge 180 on the side away from the first irregular shape edge 120; the second register unit 320 has a first side 323 and a second side 324 arranged opposite to each other in the direction from the first irregular shape edge 120 to the second irregular shape edge 180, the first side 323 and the first irregular shape edge 120 are arranged adjacent to each other, and the second side 324 and the second irregular shape edge 180 are arranged adjacent to each other.

[0128] The shapes of the first side 323 and the second side 324 are not limited here. For example, the shape of the first side 323 can be adapted to the shape of the first irregular edge 120. This allows the second register unit 320 to be arranged along the first irregular edge 120, further reducing the distance between the second register unit 320 and the first irregular edge 120, reducing the width of the border, and achieving the purpose of a narrow border.

[0129] In some alternative embodiments, the second side 324 is adapted to the shape of the second irregular edge 180. This allows the second register unit 320 to be arranged along the second irregular edge 180, further reducing the spacing between the second register unit 320 and the second irregular edge 180, reducing the width of the border, and achieving the purpose of a narrow border.

[0130] The shape of the first irregular edge 120 is not limited here. For example, the first irregular edge 120 may be arc-shaped, and two or more first edges 323 may form a first connecting edge. The first connecting edge is arc-shaped and matches the shape of the first irregular edge 120. For ease of description of the shape of multiple first edges 323, the shape formed by two or more first edges 323 is referred to as the first connecting edge. The first connecting edge does not constitute a limitation on the structure of the display panel, as long as the first edges 323 can form the first connecting edge.

[0131] Typically, the connection between adjacent sides of a display screen, especially a mobile phone display screen, is curved. The first connecting edge is curved and matches the shape of the first irregular edge 120, which can reduce the distance between two or more second register units 320 and the first irregular edge 120, thereby further reducing the area of ​​the non-display area 200 and achieving the purpose of narrow bezel.

[0132] In some alternative embodiments, the second irregular edge 180 is arc-shaped, and two or more second sides 324 constitute a second connecting edge. The second connecting edge is arc-shaped and matches the shape of the second irregular edge 180, which can reduce the spacing between two or more second register units 320 and the second irregular edge 180, thereby further reducing the area of ​​the non-display area 200 and achieving the purpose of a narrow bezel.

[0133] The second aspect of this application also provides a display device, including the display panel provided in the first aspect embodiment. The display device in this application includes, but is not limited to, mobile phones, personal digital assistants (PDAs), tablet computers, e-readers, televisions, access control systems, smart landline phones, control consoles, and other devices with display functions. Since the display device of this application includes the aforementioned display panel, the display device of this embodiment has the beneficial effects of the aforementioned display panel, which will not be elaborated further here.

[0134] This application may be implemented in other specific forms without departing from its spirit and essential characteristics. For example, the algorithm described in a particular embodiment may be modified without departing from the basic spirit of this application. Therefore, the present embodiments are to be regarded as exemplary rather than limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description, and all changes falling within the meaning and scope of the claims and their equivalents are thus included within the scope of this application.
