Description

Display panel and display device Technical Field

[0001] This application relates to the field of display technology, specifically to a display panel and display device. Background Technology

[0002] Organic light-emitting diode (OLED) display panels offer advantages over liquid crystal displays, including thinner and lighter designs, better display quality, higher resolution, wider color gamut, lower power consumption, and the ability to achieve flexible displays. These advantages have led to their rapid development in recent years, making them the preferred display panel type for many display applications.

[0003] Under-display camera (CUP) technology has been widely developed by major manufacturers because it enables full-screen display on OLED panels. OLED display panels using CUP technology generally include a CUP display area and a regular display area surrounding the CUP display area. The CUP display area includes a high-transparency area and a first display area surrounding the high-transparency area, where pixels for performing display functions are set.

[0004] In conventional OLED display panels, when the conventional display area and the first display area work together, the edge of the first display area adjacent to the conventional display area exhibits a severe jagged edge effect, and the brightness of the first display area is significantly lower than that of the conventional display area. Although increasing pixel density can improve the jagged edge effect and increase the brightness of the first display area, the pixel arrangement within the first display area has significant limitations. This means that increasing the pixel density of the first display area will substantially increase its area, thereby enlarging the bezel of the CPU display area. Consequently, the overall display effect of the OLED display panel is poor when displaying the entire screen. This problem urgently needs to be solved. Invention Overview

[0005] This application provides a display panel and display device that can effectively solve the problem in related technologies where it is difficult to reduce the bezel of the CPU display area and improve the overall display effect of the display panel while taking into account the pixel density of the first display area.

The first straight line and the second straight line together divide the first display area into four first regions.

Each first region is provided with a first pixel unit group and a second pixel unit group. The first pixel unit group includes a plurality of first pixel unit columns arranged sequentially along the first direction, and the second pixel unit group includes a plurality of second pixel unit columns arranged sequentially along the first direction.

[0037] The specific solutions of this application are described below with reference to specific embodiments.

[0038] Figure 1 is a plan view of the display panel provided in an embodiment of this application; Figure 2 is a plan view of the first display area provided in Embodiment 1 of this application; Figure 3 is a partial enlarged view of area AA in Figure 1 provided in Embodiment 1 of this application. Referring to Figures 1, 2, and 3, in a first aspect, this application provides a display panel, which can be an OLED display panel. The display panel includes a high-transparency area 10, a first display area 20, and a second display area 30. The first display area 20 surrounds the high-transparency area 10, and the second display area 30 surrounds the first display area 20. The high-transparency area 10 and the first display area 20 can be collectively referred to as the under-display camera area or CPU area, and the second display area 30 is referred to as the conventional display area.

[0039] In some embodiments of this application, the first straight line L1 and the second straight line L2 are located in the same plane and are perpendicular to each other. The first straight line L1 and the second straight line L2 together divide the first display area 20 into four first regions 21. The first straight line L1 extends along the first direction X, and the second straight line L2 extends along the second direction Y. Each first region 21 is provided with a first pixel unit group 40 and a second pixel unit group 50. The first pixel unit group 40 includes a plurality of first pixel unit columns 41 arranged sequentially along the first direction X, and the second pixel unit group 50 includes a plurality of second pixel unit columns 51 arranged sequentially along the first direction X. The first straight line L1 passes through the center of the high-transparency area 10. In the second pixel unit group 50, the distance between each second pixel unit column 51 and the first straight line L1 is equal, and the distance between each second pixel unit column 51 and the first straight line L1 is less than the distance between each first pixel unit column 41 and the first straight line L1.

[0040] In the display panel provided in this embodiment, since the distance between each second pixel unit column 51 in the second pixel unit group 50 and the first straight line L1 is equal, in the first region 21, in the second direction Y perpendicular to the first direction X, the length of the second pixel unit group 50 is equal to the length of the second pixel unit column 51 with the longest length in the second pixel unit group 50. That is, this arrangement can shorten the length of at least some pixel unit groups (such as the second pixel unit group 50) in the second direction Y, reduce the area of ​​the first region 21, thereby reducing the area of ​​the first display area 20, and thus reducing the bezel of the CUP area, improving the overall display effect of the display panel. It should be noted that since the display panel provided in Embodiment 1 of this application does not change the size and number of pixel units, the display panel provided in this application can reduce the bezel of the CUP display area and improve the overall display effect of the display panel while taking into account the pixel density of the first display area 20.

[0041] In addition, the distance between each second pixel unit column 51 and the first straight line L1 is smaller than the distance between each first pixel unit column 41 and the first straight line L1. This application improves the space utilization of the first region 21 by changing the distribution pattern of multiple second pixel unit columns 51 that are closer to the first straight line L1.

[0042] In some embodiments of this application, in a first region 21, along a direction away from the second straight line L2, the distance between a plurality of first pixel unit columns 41 and the first straight line L1 decreases sequentially.

[0043] Referring to FIG3, in the first pixel unit group 40 in the first region 21 in the upper right, the distance between the multiple first pixel unit columns 41 arranged sequentially along the first direction X and the first straight line L1 decreases sequentially.

[0044] In the display panel provided in this application embodiment, since the distances between the plurality of first pixel unit columns 41 arranged sequentially along the first direction X and the first straight line L1 increase or decrease sequentially, in the first region 21, in the second direction Y perpendicular to the first direction X, the length of the first pixel unit group 40 is greater than the length of the longest first pixel unit column 41 in the first pixel unit group 40. If the arrangement of the plurality of second pixel unit columns 51 in the second pixel unit group 50 is the same as the arrangement of the plurality of first pixel unit columns 41 in the first pixel unit group 40, the area of ​​the first display area 20 will be greatly increased, resulting in a larger border of the CUP area. This application effectively reduces the area of ​​the first display area 20 by making the distance between each second pixel unit column 51 in the second pixel unit group 50 and the first straight line L1 equal, thereby reducing the border of the CUP area and improving the overall display effect of the display panel.

[0045] In some embodiments of this application, each first pixel unit column 41 in the first pixel unit group 40 includes a plurality of first pixel units, and each second pixel unit column 51 in the second pixel unit group 50 includes a plurality of second pixel units, wherein the size of the first pixel unit is the same as the size of the second pixel unit, and / or the arrangement of the first pixel unit is the same as the arrangement of the second pixel unit.

[0046] In the display panel provided in this application embodiment, since the size of the first pixel unit is the same as the size of the second pixel unit, and / or the arrangement of the first pixel unit is the same as the arrangement of the second pixel unit, the pixel design difficulty in the first display area 20 of the display panel can be simplified, and the manufacturing cost can be reduced.

[0047] In some embodiments of this application, the arrangement of the first pixel unit and the second pixel unit includes a REAL RGB arrangement. Optionally, the conventional display area includes multiple pixel units, and the pixel units of the conventional display area are also arranged in a REAL RGB arrangement.

[0048] In the display panel provided in this application embodiment, since the display panel can reduce the bezel of the CUP display area while taking into account the pixel density of the first display area 20, the first display area 20 can be adapted to the REAL RGB arrangement method with a denser pixel arrangement and better display effect, so as to further improve the display effect of the display panel.

[0049] In some embodiments of this application, each of the first regions 21 is provided with a plurality of first driving lines 60 arranged sequentially along the first direction X, wherein the first driving line 60 electrically connected to the first pixel unit column 41 includes a straight first driving segment 61 and an arc-shaped second driving segment 62; the first driving lines 60 electrically connected to the second pixel unit column 51 may all be straight.

[0050] In the display panel provided in this embodiment, each first region 21 is provided with multiple first driving lines 60 arranged sequentially along the first direction X. The first driving lines 60 can also be referred to as vertical traces. Since the first region 21 is located on one side of the high-transparency area 10, and in order to ensure the light transmittance of the high-transparency area 10, the vertical traces are not provided in the high-transparency area 10. This causes the first driving line 60 electrically connected to the first pixel unit column 41 to not only include a straight first driving segment 61 extending along the second direction Y, but also an arc-shaped second driving segment 62 that matches the edge shape of the high-transparency area 10. Influenced by the routing method of the second driving segment 62, an inclined structure is formed in which the connecting lines of the ends of the multiple first pixel unit columns 41 away from the first edge 22 intersect the first direction X. Similarly, since the first driving lines 60 electrically connected to the second pixel unit column 51 are all straight, the second pixel unit column 51 will not be affected by the arc-shaped second driving segment 62. Therefore, it is possible to form a structure in which the line connecting the ends of multiple second pixel unit columns 51 away from the first edge 22 is parallel to the first direction X, shortening the length of the second pixel unit group 50 in the second direction Y, reducing the area of ​​the first region 21, thereby reducing the area of ​​the first display area 20, thereby reducing the bezel of the CUP area, and improving the overall display effect of the display panel.

[0051] In some embodiments of this application, in each of the first regions 21, the first pixel unit group 40 and the second pixel unit group 50 do not overlap in the second direction Y, and the first pixel unit group 40 and the second pixel unit group 50 do not overlap in the first direction X, wherein the second direction Y is perpendicular to the first direction X.

[0052] In the display panel provided in this application embodiment, since the first pixel unit group 40 and the second pixel unit group 50 do not overlap in the second direction Y and the first pixel unit group 40 and the second pixel unit group 50 in the first direction X in each of the first regions 21, the first pixel unit group 40 and the second pixel unit group 50 can be respectively set on different sides of the arc-shaped second driving segment 62, thereby making fuller use of the space of the first display area 20, minimizing the area of ​​the first display area 20, thereby reducing the bezel of the CUP area and improving the overall display effect of the display panel.

[0053] In some embodiments of this application, in the second direction Y, the ends of each second pixel unit column 51 in the second pixel unit group 50 do not exceed the opposite ends of the high-transparency area 10 in the second direction Y.

[0054] In some embodiments of this application, each pixel unit in the first pixel unit column 41 is equidistant from the second straight line L2, and each pixel unit in the second pixel unit column 51 is equidistant from the second straight line L2. The second straight line L2 extends along the second direction Y and divides the high-transparency area 10 into two sub-regions. The second direction Y is perpendicular to the first direction X.

[0055] In the display panel provided in this application embodiment, since the distance between each pixel unit in the first pixel unit column 41 and each pixel unit in the second pixel unit column 51 and the second straight line L2 is equal, each pixel unit in each pixel unit column (such as the first pixel unit column 51 or the second pixel unit column 51) can be electrically connected by straight wiring. On the one hand, this can reduce the wiring design difficulty of the first display area 20, and on the other hand, it can also reduce the wiring transition difficulty between the first display area 20 and the second display area 30.

[0056] In some embodiments of this application, in each of the first regions 21, the first pixel unit group 40 is disposed on the side of the second driving segment 62 facing or away from the second direction Y, the second pixel unit group 50 is disposed on the side of the second driving segment 62 facing or away from the first direction X, and the length of the second driving segment 62 in the second direction Y is greater than the length of the second pixel unit group 50 in the second direction Y, wherein the second direction Y is perpendicular to the first direction X.

[0057] In the display panel provided in this application embodiment, in each of the first regions 21, the first pixel unit group 40 is disposed on the side of the second driving segment 62 facing or away from the second direction Y, and the second pixel unit group 50 is disposed on the side of the second driving segment 62 facing or away from the first direction X. That is, the first pixel unit group 40 and the second pixel unit group 50 are respectively disposed on different sides of the second driving segment 62. Based on this, since the length of the second driving segment 62 in the second direction Y is greater than the length of the second pixel unit group 50 in the second direction Y, the second pixel unit group 50 disposed on the side of the second driving segment 62 facing or away from the first direction X can make full use of the vertical space (i.e., the space in the second direction Y) where the second driving segment 62 is located, thereby effectively reducing the area of ​​the first region 21, thereby reducing the area of ​​the first display area 20, thereby reducing the bezel of the CUP area, and improving the overall display effect of the display panel.

[0058] In some embodiments of this application, the spacing between two adjacent first drive segments 61 is a first distance, and the spacing between two adjacent second drives is a second distance, wherein the first distance is greater than the second distance.

[0059] In the display panel provided in this application embodiment, since the spacing between two adjacent first driving segments 61 is a first distance and the spacing between two adjacent second driving segments 62 is a second distance, the first distance is greater than the second distance. That is, the unit density of the arc-shaped second driving segment 62 is higher than that of the first driving segment 61. This also makes it possible for a larger space to be formed on the side of the second driving segment 62 facing or away from the first direction X in the first region 21, which provides conditions for the formation of the first driving line 60, which only includes the straight first driving segment 61, and the second pixel unit group 50.

[0060] In some embodiments of this application, each first region 21 is provided with a plurality of second driving lines 70 arranged sequentially along the second direction Y, wherein each second driving line 70 includes a zigzag third driving segment 71 and a straight fourth driving segment 72, the third driving segment 71 being electrically connected to a plurality of first pixel unit columns 41, and the fourth driving segment 72 being electrically connected to a plurality of second pixel unit columns 51.

[0061] In the display panel provided in this embodiment, each first area 21 is provided with multiple second driving lines 70 arranged sequentially along the second direction Y. The second driving lines 70 can also be referred to as horizontal traces. Among the second driving lines 70, the third driving segment 71 is electrically connected to multiple first pixel unit columns 41, and the fourth driving segment 72 is electrically connected to multiple second pixel unit columns 51. That is, the second driving line 70 serves to connect the first pixel unit in the first pixel unit group 40 and the second pixel unit in the second pixel unit group 50. Furthermore, the zigzag-shaped third driving segment 71 can be adapted to the inclined structure where the line connecting the ends of multiple first pixel unit columns 41 away from the first edge 22 intersects the first direction X, and the straight-shaped fourth driving segment 72 can be adapted to the structure where the line connecting the ends of multiple second pixel unit columns 51 away from the first edge 22 is parallel to the first direction X. This reduces the structural design difficulty of the first display area 20 of the display panel, reduces manufacturing costs, and improves product yield.

[0062] In some embodiments of this application, each second drive line 70 further includes a fifth drive segment 73 connecting the third drive segment 71 and the fourth drive segment 72, and the fifth drive segment 73 is straight (not shown in the figure). The distance between two adjacent third drive segments 71 is a third distance, the distance between two adjacent fourth drive segments 72 is a fourth distance, and the distance between two adjacent fifth drive segments 73 is a fifth distance. The fifth distance is less than the third distance and the fourth distance.

[0063] In the display panel provided in this application embodiment, the distance between two adjacent fifth driving segments 73 is greater than the distance between two adjacent third driving segments 71 and the distance between two adjacent fourth driving segments 72. That is, the unit density of the fifth driving segment 73 connecting the third driving segment 71 and the fourth driving segment 72 is higher than that of the third driving segment 71 and the fourth driving segment 72. The reason is that, since the line connecting the ends of the multiple first pixel unit columns 41 away from the first edge 22 intersects the first direction X, and the line connecting the ends of the multiple second pixel unit columns 51 away from the first edge 22 is parallel to the first direction X, that is, the arrangement of the pixel unit columns in the second pixel unit group 50 is different from the arrangement of the pixel unit columns in the first pixel unit group 40. This makes the acute angle between the fifth driving segment 73 and the straight line containing the first direction X further increase. At the same time, in order to ensure that the length of the first region 21 in the first direction X is minimized as much as possible, it is inevitable to squeeze the setting space of the fifth driving segment 73, thereby increasing the unit density of the fifth driving segment 73, making the fifth distance smaller than the third distance and the fourth distance.

[0064] Referring again to FIG3, in some embodiments of this application, each second drive line 70 further includes a fifth drive segment 73 connecting the third drive segment 71 and the fourth drive segment 72, and the fifth drive segment 73 is a polygonal line.

[0065] In the display panel and display device provided in this application embodiment, when the fifth driving segment 73 is a polygonal shape, the space of the first pixel unit group 40 facing or away from the second direction Y and the space of the second pixel unit group 50 facing or away from the second direction Y can be utilized more fully, thereby reducing wiring difficulty and avoiding the problem of reduced production yield caused by the small distance between two adjacent fifth driving segments 73.

[0066] In some embodiments of this application, the fifth driving segment 73 includes: a first line segment 731 connected to the third driving segment 71, a second line segment 732 connected to the fourth driving segment 72, and a third line segment 733 connecting the first line segment 731 and the second line segment 732; wherein, in the second direction Y, at least one of the first line segments 731 overlaps at least partially with the second pixel unit group 50; in the second direction Y, at least one of the second line segments 732 overlaps at least partially with the first pixel unit group 40, thereby making fuller use of the space of the first pixel unit group 40 facing or away from the second direction Y and making fuller use of the space of the second pixel unit group 50 facing or away from the second direction Y, so as to reduce the wiring difficulty and avoid the problem of reduced production yield caused by the small distance between two adjacent fifth driving segments 73.

[0067] In some embodiments of this application, the second drive line 70 includes a scan signal line, the material of which includes aluminum.

[0068] In the display panel provided in this application embodiment, the unit density of the fifth driving segment 73 is greatly increased, which makes the requirements for the electrical performance of the scanning signal lines of the display panel higher. When the sheet resistance of the scanning signal lines is large, a resistance jump can easily occur in the fifth driving segment 73, causing a decrease in the display quality of the display panel. In order to minimize the adverse effects of the resistance jump caused by the large unit density of the fifth driving segment 73 and improve the display effect of the display panel, this application uses aluminum material with better electrical performance, lower sheet resistance, and relatively low cost for the scanning signal lines.

[0069] In some embodiments of this application, the second drive line 70 further includes at least one of an enable signal line and a reset signal line, wherein the enable signal line, the reset signal line, and the scan signal line are disposed on different layers. Optionally, the second drive line 70 includes only two types of signal lines, such as a scan signal line and an enable signal line.

[0070] In the display panel provided in this application embodiment, the significantly increased unit density of the fifth driving segment 73 greatly increases the wiring difficulty of the second driving line 70. For example, when the second driving line 70 includes multiple types of signal lines, such as at least one of an enable signal line and a reset signal line in addition to the scan signal line, the wiring difficulty of the fifth driving segment 73 will be further increased, easily leading to problems such as short circuits and reduced yield. This application reduces the wiring difficulty of the second driving line 70, reduces the risk of short circuits, and improves product yield by setting the enable signal line, the reset signal line, and the scan signal line on different layers.

[0071] In some embodiments of this application, the second display area 30 includes a plurality of second regions 31, which overlap with the first region 21 in a second direction Y perpendicular to the first direction X; wherein each second region 31 includes a plurality of pixel unit columns arranged sequentially along the first direction X, wherein, in the corresponding first region 21 and second region 31, the sum of the number of the first pixel unit columns 41 and the second pixel unit columns 51 in the first region 21 is equal to the number of the third pixel unit columns 81 in the second region 31.

[0072] In the display panel provided in this application embodiment, since the sum of the number of the first pixel unit column 41 and the second pixel unit column 51 in the first region 21 is equal to the number of the third pixel unit column 81 in the second region 31, that is, in the first direction X, the number of pixel unit columns in the first display area 20 per unit length is the same as the number of pixel unit columns in the second display area 30 per unit length, thereby greatly increasing the pixel density of the first display area 20, improving the display brightness of the first display area 20, reducing the display difference between the first display area 20 and the second display area 30, and reducing the step size at the junction of the second display area 30 and the first display area 20 (i.e., the first edge 22), weakening the edge jagged effect, and improving the display effect of the display panel.

[0073] Figure 4 is another planar schematic diagram of the display panel provided in an embodiment of this application. Referring to Figures 2, 3, and 4, in some embodiments of this application, the second display area 30 includes a plurality of third areas 32, which overlap with the first area 21 in the first direction X; wherein each third area 32 includes a plurality of third pixel unit rows arranged sequentially along the second direction Y, wherein, in the corresponding first area 21 and third area 32, the sum of the number of the first pixel unit rows and the number of the second pixel unit rows in the first area 21 is a first number, and the number of the third pixel unit rows in the third area 32 is a second number, wherein the second number is twice the first number.

[0074] In the display panel provided in this application embodiment, since the number of the third pixel unit rows in the third region 32 is twice the sum of the number of the first pixel unit rows and the second pixel unit rows in the first region 21, that is, in the second direction Y, the number of pixel unit rows in the first display area 20 per unit length is less than the number of pixel unit rows in the second display area 30 per unit length, thereby appropriately reducing the number of pixel units in the first display area 20, reducing the pixel design difficulty and wiring difficulty of the first display area 20, and improving the yield of the display panel.

[0075] Of course, in other embodiments of this application, in the corresponding first region 21 and the third region 32, the sum of the number of the first pixel unit rows and the second pixel unit rows in the first region 21 can be equal to the number of the third pixel unit rows in the third region 32, so as to increase the number of pixel units in the first display area 20, thereby increasing the display brightness of the first display area 20 and weakening the display difference between the first display area 20 and the second display area 30. Alternatively, the number of the third pixel unit rows in the third region 32 is four times the sum of the number of the first pixel unit rows and the second pixel unit rows in the first region 21, so as to reduce the wiring difficulty of the first display area 20.

[0076] In some embodiments of this application, the first display area 20 is annular and includes four first regions 21. In two adjacent first regions 21 in the first direction X, two first pixel unit groups 40 are symmetrically arranged and two second pixel unit groups 50 are symmetrically arranged. In two adjacent first regions 21 in the second direction Y, two first pixel unit groups 40 are symmetrically arranged and two second pixel unit groups 50 are symmetrically arranged.

[0077] In some embodiments of this application, the first straight line L1 and the second straight line L2 together divide the first display area 20 into four first regions 21, so that the pixel unit arrangement of the first display area 20 is more regular and the wiring design of the first display area 20 is more regular, thereby reducing the manufacturing difficulty of the display panel and optimizing the display effect.

[0078] In some embodiments of this application, the first edge 22 is a circular shape including a stepped structure, but this application does not limit the shape of the first edge 22. In other embodiments of this application, the first edge 22 may also be a rectangular shape including a stepped structure.

[0079] Secondly, according to Embodiment 1 of this application, a display device is provided, the display device including an optical element and a display panel as described in any of the above claims, the optical element being disposed on the backlight side of the display panel and corresponding to the high transmittance area 10.

The first display area 20 surrounds the high-transparency area 10, and the second display area 30 surrounds the first display area 20. A first straight line L1 and a second straight line L2 are located in the same plane and are perpendicular to each other. The first straight line L1 and the second straight line L2 together divide the first display area 20 into four first regions 21. The first straight line L1 extends along a first direction X, and the second straight line L2 extends along a second direction Y. Each first region 21 is provided with a first... The system comprises a pixel unit group 40 and a second pixel unit group 50. The first pixel unit group 40 includes a plurality of first pixel unit columns 41 arranged sequentially along a first direction X, and the second pixel unit group 50 includes a plurality of second pixel unit columns 51 arranged sequentially along the first direction X. The first straight line L1 passes through the center of the high-transparency area 10. In the second pixel unit group 50, the distance between each second pixel unit column 51 and the first straight line L1 is equal, and the distance between each second pixel unit column 51 and the first straight line L1 is less than the distance between each first pixel unit column 41 and the first straight line L1.

[0082] It should be noted that the structure of the display panel and display device provided in Embodiment 2 of this application is similar to the structure of the display panel and display device provided in Embodiment 1 of this application, and the same parts will not be described again in Embodiment 2 of this application.

[0083] In some embodiments of this application, in a first region 21, along a direction away from the second straight line L2, the first pixel unit group 40 sequentially includes a straight segment K1 and a stepped segment K2. In the straight segment K1, the distance between each first pixel unit column 41 and the first straight line L1 is equal. In the stepped segment, the distance between multiple first pixel unit columns 41 and the second straight line L2 decreases sequentially.

[0084] In some embodiments of this application, in the first pixel unit group 40, the distance between each first pixel unit column 41 and the first straight line L1 is equal; wherein, each second driving line 70 includes a straight third driving segment 71 and a straight fourth driving segment 72, the third driving segment 71 is electrically connected to a plurality of first pixel unit columns 41, the fourth driving segment 72 is electrically connected to a plurality of second pixel unit columns 51, and the second direction Y is perpendicular to the first direction X.

[0085] In the display panel and display device provided in this application embodiment, since the distance between each first pixel unit column 41 and the first straight line L1 in the first pixel unit group 40 is equal, the shape of the second driving line 70 can be adjusted by optimizing the approach of a portion of the first pixel unit columns 41 in the first pixel unit group 40. This avoids the problem of increased wiring difficulty caused by setting the third driving segment 71 in the second driving line 70 to a zigzag shape, thereby improving the production yield of the display panel.
