Description

Technical Field

[0001] The present application relates to the field of display technology, and in particular to a display panel and a display device. Background Art

[0002] Organic Light Emitting Diode (OLED) display technology has become a research hotspot in the field of optoelectronic display technology due to its advantages such as self-luminescence, wide viewing angle, high contrast, low power consumption, extremely high response speed, ultra-light weight, flexible display, rollable screen, strong temperature adaptability, and simple manufacturing process. The method of using inkjet printing (IJP) to prepare corresponding devices has attracted much attention due to its high material utilization rate. However, when using inkjet printing to prepare a display device, in order to ensure the uniformity of film formation in the display area and the uniformity of the brightness of the light-emitting device, in addition to printing the light-emitting material in the display area, virtual pixels are generally printed with the same material around the display area to ensure the uniformity of film formation in the display area. However, setting more virtual pixels will result in a larger border of the display panel. Summary of the Invention

[0003] Embodiments of the present application provide a display panel and a display device to reduce the border of the display panel, thereby at least partially solving the above-mentioned technical problems.

[0004] In order to achieve the above-mentioned objective, according to a first aspect of the present application, a display panel is provided, comprising:

[0005] a substrate having a display area and a non-display area located around the display area, the non-display area including a first lateral redundant pixel area and a second lateral redundant pixel area, the second lateral redundant pixel area being located on at least one side of the display area in a first direction, and the first lateral redundant pixel area being located between the second lateral redundant pixel area and the display area;

[0006] a plurality of display pixels located on the substrate in the display area;

[0007] a first lateral redundant pixel, located on the substrate in the first lateral redundant pixel region, wherein the area of ​​the first lateral redundant pixel is the same as the area of ​​at least one of the display pixels;

[0008] A plurality of second lateral redundant pixels extend along the first direction and are arranged at intervals along the second direction. The pixels are located on the substrate in a second lateral redundant pixel region. A size of one second lateral redundant pixel along the first direction is larger than a size of at least one first lateral redundant pixel along the first direction. The first direction intersects the second direction.

[0009] According to a second aspect of the present application, a display device is provided, comprising the above-mentioned display panel.

[0010] In the display panel and display device of the embodiments of the present application, the area of ​​the first lateral redundant pixel is the same as the area of ​​at least one display pixel. Therefore, the total number of ink droplets required to form the first lateral redundant pixel is the same as the total number of ink droplets required to form the at least one display pixel. The first lateral redundant pixel region is located at the edge of the display area. After the ink droplets dry, the edges with uneven film thickness are first located in the first lateral redundant pixel region. In other words, the first lateral redundant pixel acts as a buffer against uneven thickness of the display pixels in the display area in the first direction.

[0011] Furthermore, multiple second lateral redundant pixels extend along the first direction and are spaced apart along the second direction. The size of the second lateral redundant pixels along the first direction is greater than the size of at least one first lateral redundant pixel along the first direction. Along the first direction, the number of ink droplets required to form the second lateral redundant pixels is greater than the number of ink droplets required to form at least one first lateral redundant pixel. The larger number of ink droplets contains more solvent, reducing the solvent volatilization rate in the second lateral redundant pixel region. The solvent volatilization rate in the outer second lateral redundant pixel region tends to be the same as the lower solvent volatilization rate in the inner display area, reducing the risk of ink in the display area flowing from the display area to the non-display area along the first direction. In this way, the problem of uneven thickness of display pixels in the display area along the first direction is also alleviated, which helps reduce the total size of the non-display area in the first direction, thereby reducing the size of the non-display area of ​​the display panel along the first direction.

[0025] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0026] See also Figures 1 to 4 As shown, an embodiment of the present application provides a display panel 100. The display panel 100 may be at least one of an organic light emitting diode display panel and a quantum dot display panel. In an exemplary embodiment, the display panel 100 is an organic light emitting diode display panel.

[0027] The display panel 100 includes a substrate 11. In some embodiments, the substrate 11 may include at least one of a flexible substrate and a rigid substrate. The flexible substrate may include an organic substrate. The rigid substrate may include a glass substrate.

[0028] The substrate 11 has a display area 11A and a non-display area 11B surrounding the display area 11A. The portion of the display panel 100 corresponding to the display area 11A can emit light to achieve display. The portion of the display panel 100 corresponding to the non-display area 11B cannot emit light.

[0029] The display panel 100 further includes a plurality of display pixels 121. The plurality of display pixels 121 are located on the substrate 11 in the display area 11A.

[0030] In some embodiments, the plurality of display pixels 121 includes a plurality of display pixel rows 121A. Each display pixel row 121A includes at least two display pixels 121 arranged side by side along a first direction X. At least two display pixels 121 in a display pixel row 121A emit light of the same color. The plurality of display pixel rows 121A are arranged along a second direction Y. Two display pixels 121 in adjacent display pixel rows 121A emit light of different colors. The second direction Y intersects the first direction X.

[0031] In an exemplary embodiment, the plurality of display pixel rows 121A include a first display pixel row, a second display pixel row, and a third display pixel row arranged at intervals along a second direction Y. Adjacent first display pixel rows, second display pixel rows, and third display pixel rows are repeatedly arranged along the second direction Y as a repeating unit. The first display pixel row includes at least two first display pixels arranged along a first direction X. The second display pixel row includes at least two second display pixels arranged along the first direction X. The third display pixel row includes at least two third display pixels arranged along the first direction X. The first display pixel, the second display pixel, and the third display pixel each emit light of three different colors, such as red light, blue light, and green light.

[0032] In some embodiments, the shape of the display pixel 121 is selected from at least one of a circle, an ellipse, and a polygon. The polygon includes at least one of a square, a rhombus, a pentagon, a hexagon, and an octagon. In an exemplary embodiment, the shape of the display pixel 121 is a rectangle.

[0033] In an exemplary embodiment, the first direction X is perpendicular to the second direction Y, but the present invention is not limited thereto. The angle between the first direction X and the second direction Y may also be an acute angle or an obtuse angle.

[0034] In some embodiments, as Figure 1 As shown, the first direction X is the width direction of the display panel 100, and the second direction Y is the length direction of the display panel 100. The length of the display panel 100 may be greater than or equal to the width of the display panel 100. In other embodiments, the first direction X may be the length direction of the display panel 100, and the second direction Y may be the width direction of the display panel 100.

[0035] See also Figure 1 As shown, the non-display area 11B includes a first lateral redundant pixel area 11B1 and a second lateral redundant pixel area 11B2 .

[0036] In the first direction X, the first lateral redundant pixel region 11B1 is adjacent to the display region 11A. In an exemplary embodiment, see Figure 1 As shown, along the first direction X, the display area 11A is located between the two first lateral redundant pixel areas 11B1 , that is, the two first lateral redundant pixel areas 11B1 are located at the outer edges of the display area 11A.

[0037] The first lateral redundant pixel region 11B1 extends along the second direction Y. The size of the first lateral redundant pixel region 11B1 along the second direction Y is greater than the size of the first lateral redundant pixel region 11B1 along the first direction X. In an exemplary embodiment, the shape of the first lateral redundant pixel region 11B1 is rectangular, but is not limited thereto.

[0038] In some embodiments, see Figures 1 to 3 As shown, the display panel 100 further includes a first lateral redundant pixel 122. The first lateral redundant pixel 122 is located on the substrate 11 in the first lateral redundant pixel region 11B1.

[0039] The area of ​​the first lateral redundant pixel 122 is the same as the area of ​​the at least one display pixel 121. Therefore, the total number of ink droplets required to form the first lateral redundant pixel 122 is approximately the same as the total number of ink droplets required to form the at least one display pixel 121. The first lateral redundant pixel region 11B1 is located at the edge of the display area 11A in the first direction X. After the ink droplets dry, the edges with uneven film thickness are initially located in the first lateral redundant pixel region 11B1. In other words, the first lateral redundant pixels 122 in the first lateral redundant pixel region 11B1 act as a buffer against uneven thickness of the display pixels 121 in the display area 11A in the first direction X.

[0040] In some embodiments, the shape of the first lateral redundant pixel 122 is the same as the shape of the at least one display pixel 121. This facilitates ensuring that the area of ​​the first lateral redundant pixel 122 is the same as the area of ​​the at least one display pixel 121. For example, in one exemplary embodiment, the shape of the first lateral redundant pixel 122 and the shape of the display pixel 121 are both rectangular, but the present invention is not limited thereto. In another exemplary embodiment, the shape of the first lateral redundant pixel 122 and the shape of the display pixel 121 can both be circular, elliptical, or the like.

[0041] In some embodiments, when the shape of the first lateral redundant pixel 122 is the same as the shape of the at least one display pixel 121, the size of the first lateral redundant pixel 122 along the first direction X is equal to the size of the one display pixel 121 along the first direction X, and the size of the first lateral redundant pixel 122 along the second direction Y is equal to the size of the one display pixel 121 along the second direction Y. In this way, the area of ​​the first lateral redundant pixel 122 is the same as or close to the same as the area of ​​the at least one display pixel 121.

[0042] It should be noted that, in the present application, the size of each pixel along the first direction X and the second direction Y is equal to the maximum size of each pixel along the first direction X and the second direction Y. For example, the size of the first lateral redundant pixel 122 along the first direction X is equal to the maximum size of the first lateral redundant pixel 122 along the first direction X. The size of the first lateral redundant pixel 122 along the second direction Y is equal to the maximum size of the first lateral redundant pixel 122 along the second direction Y.

[0043] In some embodiments, the thickness of the first lateral redundant pixel 122 is equal to the thickness of the at least one display pixel 121. Thus, the total amount of ink droplets used to form the first lateral redundant pixel 122 can be the same as the total amount of ink droplets used to form the at least one display pixel 121. The formation process of the first lateral redundant pixel 122 mitigates uneven thickness of the display pixels 121 in the display area 11A in the first direction X.

[0044] In some embodiments, see Figure 2 and Figure 3 As shown, in a first lateral redundant pixel region 11B1, the number of first lateral redundant pixels 122 along the first direction X is M, where M is a positive integer. The greater the number of first lateral redundant pixels 122 along the first direction X, the better the first lateral redundant pixel region 11B1 buffers uneven thickness of the display pixels 121 in the display area 11A along the first direction X. The fewer the number of first lateral redundant pixels 122 along the first direction X, the smaller the size of the first lateral redundant pixel region 11B1 in the first direction X, thereby reducing the size of the non-display area 11B in the first direction X.

[0045] Optionally, M is greater than or equal to 1 and less than or equal to 6, ensuring that an appropriate number of first lateral redundant pixels 122, which are substantially the same as the display pixels 121, are present outside the display area 11A. In this manner, a portion of the first lateral redundant pixels 122 is retained to function as a buffer in the first direction X. Furthermore, the space occupied by the first lateral redundant pixel region 11B1 in the first direction X is reduced, providing space for the second lateral redundant pixels 123 described below.

[0046] In one exemplary embodiment, see Figure 2 and Figure 3 As shown, in a first lateral redundant pixel area 11B1 , along the first direction X, the number of the first lateral redundant pixel 122 is one.

[0047] In another exemplary embodiment, in one first lateral redundant pixel region 11B1 , the number of first lateral redundant pixels 122 along the first direction X is three.

[0048] In some embodiments, when the plurality of display pixels 121 include a plurality of display pixel rows 121A arranged at intervals along the second direction Y, a first lateral redundant pixel region 11B1 is provided with a plurality of first lateral redundant pixels 122 arranged at intervals along the second direction Y. At least two display pixels 121 in a display pixel row 121A and at least one first lateral redundant pixel 122 are arranged side by side along the first direction X. This facilitates simplifying the process of forming the display pixels 121 and the first lateral redundant pixels 122.

[0049] In some embodiments, the first lateral redundant pixels 122 and the display pixels 121 disposed side by side are made of the same material. In this way, the first lateral redundant pixels 122 and the display pixels 121 disposed side by side can be continuously formed using the same ink droplets, which helps simplify the formation process of both.

[0050] See Figure 1 As shown, the second lateral redundant pixel region 11B2 is located on at least one side of the display region 11A in the first direction X. The first lateral redundant pixel region 11B1 is located between the second lateral redundant pixel region 11B2 and the display region 11A. As such, the second lateral redundant pixel region 11B2 can be located at the outermost side of the display panel 100 in the first direction X.

[0051] The second lateral redundant pixel region 11B2 extends along the second direction Y. The size of the second lateral redundant pixel region 11B2 along the second direction Y is greater than the size of the second lateral redundant pixel region 11B2 along the first direction X. In this way, the size of the second lateral redundant pixel region 11B2 along the first direction X is reduced, and the size of the non-display area 11B along the first direction X is reduced.

[0052] In an exemplary embodiment, along the first direction X, two second lateral redundant pixel regions 11B2 are respectively located at opposite sides of the display region 11A.

[0053] See Figure 2 and Figure 3As shown, the display panel 100 further includes a plurality of second lateral redundant pixels 123. These plurality of second lateral redundant pixels 123 extend along the first direction X and are spaced apart along the second direction Y. They are located on the substrate 11 in a second lateral redundant pixel region 11B2. A dimension XC2 of a second lateral redundant pixel 123 along the first direction X is greater than a dimension XC1 of at least one first lateral redundant pixel 122 along the first direction X. Therefore, along the first direction X, the number of ink droplets required to form a second lateral redundant pixel 123 is greater than the number of ink droplets required to form at least one first lateral redundant pixel 122. This greater number of ink droplets contains more solvent, reducing the solvent evaporation rate in the second lateral redundant pixel region 11B2. The solvent evaporation rate in the outer second lateral redundant pixel region 11B2 tends to be similar to the slower solvent evaporation rate in the inner display area 11A, reducing the risk of ink in the display area 11A flowing from the display area 11A to the non-display area 11B along the first direction X. In this way, the problem of uneven thickness of the display pixels 121 of the display area 11A along the first direction X is also improved, which is conducive to reducing the total size of the non-display area 11B in the first direction X, thereby reducing the size of the non-display area 11B of the display panel 100 along the first direction X.

[0054] It should be noted that the embodiment of the present application compresses the size of the second lateral redundant pixel area 11B2 along the first direction X and increases the total amount of ink droplets in this area to create a large amount of solvent atmosphere to improve the uneven thickness of the display pixels 121 in the first direction X, thereby achieving the purpose of a narrow frame along the first direction X.

[0055] In some embodiments, a ratio of a dimension XC2 of a second lateral redundant pixel 123 along the first direction X to a dimension XC1 of at least one first lateral redundant pixel 122 along the first direction X is greater than or equal to 2. Thus, a larger number of ink droplets are required to form the second lateral redundant pixel 123 along the first direction X. A larger number of ink droplets contains more solvent, further reducing the volatilization rate of the solvent in the second lateral redundant pixel region 11B2.

[0056] In some embodiments, a ratio of a size XC2 of one second lateral redundant pixel 123 along the first direction X to a size XC1 of at least one first lateral redundant pixel 122 along the first direction X is less than or equal to 15. In this way, the size occupied by the second lateral redundant pixel 123 along the first direction X is reduced, and the size of the non-display area 11B along the first direction X is reduced.

[0057] Optionally, a ratio of a dimension XC2 of the second lateral redundant pixel 123 along the first direction X to a dimension XC1 of the at least one first lateral redundant pixel 122 along the first direction X may be 3 to 12, 3 to 8, or 5 to 15. In this way, while improving the uneven thickness problem of the display pixels 121 along the first direction X, the dimension of the non-display area 11B along the first direction X is also reduced.

[0058] It is understandable that the ratio of the dimension XC2 of one second lateral redundant pixel 123 along the first direction X to the dimension XC1 of at least one first lateral redundant pixel 122 along the first direction X can be any value between 2 and 15, such as 2, 3, 5, 7, 9, 11, 13, or 15.

[0059] In some embodiments, see Figure 2 and Figure 3 As shown, one second lateral redundant pixel 123 extends along the first direction X to opposite ends of the second lateral redundant pixel 123, respectively adjacent to the edges of the first lateral redundant pixel region 11B1 and the non-display region 11B. This increases the dimension XC2 of the second lateral redundant pixel 123 along the first direction X, resulting in a larger area for the second lateral redundant pixel 123. This increases the total amount of ink droplets required to form the second lateral redundant pixel 123, further reducing the solvent volatilization rate in the second lateral redundant pixel region 11B2. Furthermore, along the first direction X, there is only one second lateral redundant pixel 123, thereby achieving a narrow bezel for the display panel 100.

[0060] In other embodiments, along the first direction X, the number of the second lateral redundant pixels 123 may be two or more, thereby increasing the design flexibility of the second lateral redundant pixels 123 and further increasing the flexibility of achieving a narrow-framed display panel 100 .

[0061] In some embodiments, see Figure 2As shown, when the dimension XC2 of a second lateral redundant pixel 123 along the first direction X is greater than the dimension XC1 of at least one first lateral redundant pixel 122 along the first direction X, the dimension YC2 of a second lateral redundant pixel 123 along the second direction Y can be equal to the dimension YC1 of at least one first lateral redundant pixel 122 along the second direction Y. In this way, the area of ​​a second lateral redundant pixel 123 is greater than the area of ​​at least one first lateral redundant pixel 122. The total amount of ink droplets required to form the second lateral redundant pixel 123 is greater than the total amount of ink droplets required to form the first lateral redundant pixel 122, reducing the evaporation rate of the solvent in the second lateral redundant pixel region 11B2. The evaporation rate of the solvent in the outer second lateral redundant pixel region 11B2 tends to be the same as the slower evaporation rate of the solvent in the inner display area 11A, reducing the risk of ink in the display area 11A flowing from the display area 11A to the non-display area 11B along the first direction X. In this way, the problem of uneven thickness of the display pixels 121 of the display area 11A along the first direction X is also improved, which is conducive to reducing the total size of the non-display area 11B in the first direction X, thereby reducing the size of the non-display area 11B of the display panel 100 along the first direction X.

[0062] In some embodiments, see Figure 2 As shown, when the dimension YC2 of a second lateral redundant pixel 123 along the second direction Y is equal to the dimension YC1 of a first lateral redundant pixel 122 along the second direction Y, a second lateral redundant pixel 123 can be arranged side by side with at least one first lateral redundant pixel 122 along the first direction X, thereby simplifying the formation process of the second lateral redundant pixels 123 and the first lateral redundant pixels 122. Furthermore, when the first lateral redundant pixels 122 and the display pixel row 121A are arranged side by side along the first direction X, the second lateral redundant pixels 123 can better alleviate the problem of uneven thickness of the display pixels 121 along the first direction X.

[0063] In other embodiments, see Figure 3 As shown, when the dimension XC2 of a second lateral redundant pixel 123 along the first direction X is greater than the dimension XC1 of at least one first lateral redundant pixel 122 along the first direction X, the dimension YC2 of a second lateral redundant pixel 123 along the second direction Y may also be greater than the dimension YC1 of a first lateral redundant pixel 122 along the second direction Y. In this way, the area of ​​a second lateral redundant pixel 123 is greater than the area of ​​at least one first lateral redundant pixel 122.

[0064] In some other embodiments, a ratio of a dimension YC2 of a second lateral redundant pixel 123 along the second direction Y to a dimension YC1 of a first lateral redundant pixel 122 along the second direction Y is less than or equal to the number of first lateral redundant pixels 122 in the first lateral redundant pixel column. The first lateral redundant pixel column includes at least two first lateral redundant pixels 122 arranged side by side along the second direction Y. The number of first lateral redundant pixels 122 in the first lateral redundant pixel column can be equal to the number of display pixel rows 121A along the second direction Y.

[0065] Optionally, a ratio of a dimension YC2 of a second lateral redundant pixel 123 along the second direction Y to a dimension YC1 of a first lateral redundant pixel 122 along the second direction Y may be greater than or equal to 2 and less than or equal to 50. Optionally, a ratio of a dimension YC2 of a second lateral redundant pixel 123 along the second direction Y to a dimension YC1 of a first lateral redundant pixel 122 along the second direction Y may be 3-30, 4-25, 5-20, or 6-15.

[0066] In other embodiments, when the dimension YC2 of a second lateral redundant pixel 123 along the second direction Y is greater than or equal to the dimension YC1 of a first lateral redundant pixel 122 along the second direction Y, two or more first lateral redundant pixels 122 arranged side by side along the second direction Y may be arranged side by side with one second lateral redundant pixel 123 along the first direction X.

[0067] In one exemplary embodiment, see Figure 3 As shown, two adjacent first lateral redundant pixels 122 arranged side by side along the second direction Y may be arranged side by side with one second lateral redundant pixel 123 along the first direction X. The two adjacent first lateral redundant pixels 122 arranged side by side along the second direction Y are respectively arranged side by side with two adjacent display pixel rows 121A (e.g., the first display pixel row and the second display pixel row).

[0068] In another exemplary embodiment, three adjacent first lateral redundant pixels 122 arranged side by side along the second direction Y may be arranged side by side with one second lateral redundant pixel 123 along the first direction X. The three adjacent first lateral redundant pixels 122 arranged side by side along the second direction Y are respectively arranged side by side with three adjacent display pixel rows 121A (e.g., the first to third display pixel rows).

[0069] In yet another exemplary embodiment, six adjacent first lateral redundant pixels 122 arranged side by side along the second direction Y may be arranged side by side with one second lateral redundant pixel 123 along the first direction X. The six adjacent first lateral redundant pixels 122 arranged side by side along the second direction Y are respectively arranged side by side with six adjacent display pixel rows 121A (e.g., two groups of first to third display pixel rows).

[0070] In some embodiments, the second lateral redundant pixels 123 may be strip-shaped structures extending along the first direction X. The strip-shaped structure design allows the second lateral redundant pixels 123 to fully utilize the space of the non-display area 11B in the first direction X while simplifying the formation of the second lateral redundant pixels 123 .

[0071] In some embodiments, the distance between two adjacent second lateral redundant pixels 123 along the second direction Y can be equal to the distance between two adjacent display pixel rows 121A. In some embodiments, the distance between two adjacent second lateral redundant pixels 123 along the second direction Y is equal to the distance between two adjacent first lateral redundant pixels 122.

[0072] In some embodiments, the thickness of the second lateral redundant pixel 123 is greater than or equal to the thickness of the display pixel 121 and the first lateral redundant pixel 122. Thus, the total amount of ink droplets required to form the second lateral redundant pixel 123 can be greater than or equal to the total amount of ink droplets required to form the display pixel 121 and the first lateral redundant pixel 122. The formation process of the second lateral redundant pixel 123 can better alleviate the problem of uneven thickness of the display pixel 121 along the first direction X, thereby reducing the size of the non-display area 11B along the first direction X.

[0073] Optionally, the thickness of the second lateral redundant pixel 123 is greater than the thickness of the display pixel 121 and the first lateral redundant pixel 122. In this way, the total amount of ink droplets required to form the second lateral redundant pixel 123 is greater than the total amount of ink droplets required to form the display pixel 121 and the first lateral redundant pixel 122. The formation process of the second lateral redundant pixel 123 can better improve the problem of uneven thickness of the display pixel 121 along the first direction X, thereby reducing the size of the non-display area 11B along the first direction X.

[0074] The non-display area 11B further includes a corner redundant pixel area 11B5. The corner redundant pixel area 11B5 is located at a corner of the non-display area 11B and is adjacent to the second lateral redundant pixel area 11B2. Figure 2 and Figure 3 As shown, the four corner redundant pixel areas 11B5 are respectively located at the four corners of the non-display area 11B.

[0075] In some embodiments, the display panel 100 further includes corner redundant pixels 126. Corner redundant pixels 126 are located in corner redundant pixel region 11B5. The thickness of corner redundant pixels 126 is greater than or equal to the thickness of the first lateral redundant pixels 122 and the second lateral redundant pixels 123. Therefore, the total number of ink droplets required to form corner redundant pixels 126 is greater than or equal to the total number of ink droplets required to form the second lateral redundant pixels 123 and the first lateral redundant pixels 122. The large amount of solvent in the ink droplets forming corner redundant pixels 126 provides a solvent atmosphere for the drying process of the ink droplets in corner redundant pixel region 11B5, reducing the solvent evaporation rate in corner redundant pixel region 11B5. The solvent evaporation rate in corner redundant pixel region 11B5 is similar to that of the solvent in the display area 11A, reducing the risk of ink flowing from the corners of the display area 11A to the corners of the non-display area 11B. In this way, the problem of uneven thickness of the display pixels 121 at the corners of the display area 11A due to the flow of ink to the corners of the non-display area 11B is improved, which is conducive to reducing the size of the corner redundant pixel area 11B5 in the non-display area 11B and further reducing the border of the display panel 100.

[0076] It should be noted that in related technologies, when ink printing is used to form display pixels, severe display unevenness may occur at the corners of the display area. In some embodiments of the present application, the addition of the aforementioned corner redundant pixels 126 in the non-display area 11B can significantly improve the uneven thickness of the display pixels 121 at the corners of the display area 11A, thereby improving the display unevenness that may occur at the corners of the display area 11A.

[0077] Optionally, the thickness of the corner redundant pixel 126 is greater than the thickness of the first lateral redundant pixel 122 and the second lateral redundant pixel 123. The total amount of ink droplets required to form the corner redundant pixel 126 is greater than the total amount of ink droplets required to form the second lateral redundant pixel 123 and the first lateral redundant pixel 122. The formation process of the corner redundant pixel 126 can better improve the uneven thickness of the display pixels 121 at the corners of the display area 11A.

[0078] In some embodiments, the area of ​​a corner redundant pixel 126 is larger than the area of ​​the first lateral redundant pixel 122 and the second lateral redundant pixel 123. Thus, the total amount of ink droplets required to form the corner redundant pixel 126 is greater than the total amount of ink droplets required to form the first lateral redundant pixel 122 and the second lateral redundant pixel 123. The process of forming the corner redundant pixel 126 can effectively reduce the evaporation rate of the solvent at the corner of the non-display area 11B, thereby improving the uneven thickness of the display pixels 121 at the corners of the display area 11A.

[0079] In some embodiments, the area of ​​a corner redundant pixel 126 is larger than the area of ​​a display pixel 121. Thus, the total amount of ink droplets required to form the corner redundant pixel 126 is greater than the total amount of ink droplets required to form the display pixel 121. The process of forming the corner redundant pixel 126 can further reduce the evaporation rate of the solvent at the corner of the non-display area 11B, thereby improving the uneven thickness of the display pixels 121 at the corner of the display area 11A.

[0080] In some embodiments, a dimension XZ1 of the corner redundant pixel 126 along the first direction X is equal to a dimension XC2 of the second lateral redundant pixel 123 along the first direction X, and a dimension YZ1 of the corner redundant pixel 126 along the second direction Y is greater than a dimension YC2 of the second lateral redundant pixel 123 along the second direction Y. Thus, the area of ​​the corner redundant pixel 126 is greater than the area of ​​the second lateral redundant pixel 123.

[0081] In some embodiments, a corner redundant pixel 126 extends along the second direction Y until its two opposite ends are adjacent to the edges of the second lateral redundant pixel region 11B2 and the non-display region 11B. Thus, the size of the corner redundant pixel 126 along the second direction Y is large enough to increase the area of ​​the corner redundant pixel 126.

[0082] See Figure 2 and Figure 3 As shown, the corner redundant pixel 126 and the second lateral redundant pixel 123 are arranged side by side along the second direction Y, which simplifies the formation process of the corner redundant pixel 126 and the second lateral redundant pixel 123 .

[0083] In some embodiments, see Figure 2 and Figure 3 As shown, the redundant corner pixels 126 are strip-shaped. For example, the redundant corner pixels 126 are rectangular. This strip-shaped design allows the redundant corner pixels 126 to more fully utilize the space at the corners of the non-display area 11B while simplifying the formation of the redundant corner pixels 126. In some embodiments, the redundant corner pixels 126 may also have other shapes, such as an L-shape.

[0084] In some embodiments, in a corner redundant pixel area 11B5, the number of corner redundant pixels 126 may be one or more. Figure 2 and Figure 3 As shown, in a corner redundant pixel area 11B5, the number of corner redundant pixels 126 may be one.

[0085] In a corner redundant pixel area 11B5 , a plurality of corner redundant pixels 126 may be arranged at intervals along at least one of the first direction X and the second direction Y. The areas of the plurality of corner redundant pixels 126 may be the same or different.

[0086] See Figure 1 As shown, the non-display area 11B further includes a third lateral redundant pixel region 11B3. The third lateral redundant pixel region 11B3 is adjacent to the display area 11A along the second direction Y. In the first direction X, the third lateral redundant pixel region 11B3 extends along the first direction X and is located between the two second lateral redundant pixel regions 11B2.

[0087] In an exemplary embodiment, along the second direction Y, the display area 11A is located between two third lateral redundant pixel areas 11B3 .

[0088] See Figure 2 and Figure 3 As shown, the display panel 100 further includes a third lateral redundant pixel 124. The third lateral redundant pixel 124 is located on the substrate 11 in a third lateral redundant pixel region 11B3. The area of ​​the third lateral redundant pixel 124 is the same as the area of ​​at least one display pixel 121. As such, the total number of ink droplets required to form the third lateral redundant pixel 124 is the same as the total number of ink droplets required to form at least one display pixel 121. The third lateral redundant pixel region 11B3 is located at the edge of the display area 11A in the second direction Y. After the ink droplets dry, the edges with uneven film thickness are first located in the third lateral redundant pixel region 11B3. In other words, the third lateral redundant pixel 124 in the third lateral redundant pixel region 11B3 acts as a buffer against uneven thickness of the display pixels 121 in the display area 11A in the second direction Y.

[0089] In some embodiments, the shape of the third lateral redundant pixel 124 is the same as that of at least one display pixel 121 , so that the area of ​​the third lateral redundant pixel 124 is advantageously the same as that of the display pixel 121 .

[0090] In some embodiments, when the shape of the third lateral redundant pixel 124 is the same as the shape of at least one display pixel 121, the size of the third lateral redundant pixel 124 along the first direction X is equal to the size of the display pixel 121 along the first direction X, and the size of the third lateral redundant pixel 124 along the second direction Y is equal to the size of the display pixel 121 along the second direction Y. In this way, the area of ​​the third lateral redundant pixel 124 is advantageously equal to the area of ​​the at least one display pixel 121.

[0091] In some embodiments, the thickness of the third lateral redundant pixel 124 is equal to the thickness of the at least one display pixel 121. Thus, the total amount of ink droplets used to form the third lateral redundant pixel 124 can be the same as the total amount of ink droplets used to form the at least one display pixel 121. The formation process of the third lateral redundant pixel 124 mitigates uneven thickness of the display pixels 121 in the display area 11A in the first direction X.

[0092] In some embodiments, see Figure 2 and Figure 3 As shown, in a third lateral redundant pixel region 11B3, the number of third lateral redundant pixels 124 along the second direction Y is N, where N is greater than M. When the plurality of display pixels 121 include a plurality of different display pixel rows 121A (e.g., first to third display pixel rows) arranged alternately along the second direction Y, the number and design of third lateral redundant pixels 124 along the second direction Y in third lateral redundant pixel region 11B3 are related to the number and design of different display pixel rows 121A. For example, when the number of different display pixel rows 121A is 3, the number of third lateral redundant pixels 124 along the second direction Y in third lateral redundant pixel region 11B3 needs to be greater than or equal to 3. The number of first lateral redundant pixels 122 along the first direction X in first lateral redundant pixel region 11B1 generally only needs to be greater than or equal to 1. The number of different display pixel rows 121A is generally greater than 1. Therefore, N is greater than M to meet the buffering requirements of the third lateral redundant pixels 124 from a plurality of different display pixel rows 121A (eg, the first to third display pixel rows) arranged at intervals along the second direction Y.

[0093] In an exemplary embodiment, when the plurality of display pixel rows 121A include the first to third display pixel rows described above, the plurality of third lateral redundant pixels 124 also include a first redundant pixel row, a second redundant pixel row, and a third redundant pixel row arranged at intervals along the second direction Y. The first redundant pixel row includes a first type of redundant pixels, which are identical to the first display pixels. The second redundant pixel row includes a second type of redundant pixels, which are identical to the second display pixels. The third redundant pixel row includes a third type of redundant pixels, which are identical to the third display pixels. The first redundant pixel row, the second redundant pixel row, and the third redundant pixel row are arranged in the same direction as the first to third display pixel rows.

[0094] In some embodiments, in the second direction Y, at least two third lateral redundant pixels 124 in each redundant pixel row are arranged side by side with at least two display pixels 121 in one display pixel row 121A in a one-to-one manner.

[0095] See Figure 1As shown, the non-display area 11B further includes a fourth lateral redundant pixel area 11B4 located on at least one side of the display area 11A in the second direction Y, and the third lateral redundant pixel area 11B3 located between the fourth lateral redundant pixel area 11B4 and the display area 11A.

[0096] See Figure 2 and Figure 3 As shown, the display panel 100 further includes a fourth lateral redundant pixel 125. The fourth lateral redundant pixel 125 is located on the substrate 11 in a fourth lateral redundant pixel region 11B4. The thickness of the fourth lateral redundant pixel 125 is greater than or equal to the thickness of the third lateral redundant pixel 124 and the thickness of the display pixel 121. Therefore, the total amount of ink droplets required to form the fourth lateral redundant pixel 125 is greater than or equal to the total amount of ink droplets required to form the third lateral redundant pixel 124 and the display pixel 121, thereby reducing the evaporation rate of the solvent in the fourth lateral redundant pixel region 11B4. The evaporation rate of the solvent in the outer fourth lateral redundant pixel region 11B4 tends to be the same as the slower evaporation rate of the solvent in the inner display area 11A, thereby reducing the risk of ink in the display area 11A flowing from the display area 11A to the non-display area 11B along the second direction Y. In this way, the problem of uneven thickness of the display pixels 121 of the display area 11A along the second direction Y is also improved, which is conducive to reducing the total size of the non-display area 11B in the second direction Y, thereby reducing the size of the non-display area 11B of the display panel 100 along the second direction Y.

[0097] It should be noted that the embodiment of the present application compresses the size of the fourth lateral redundant pixel area 11B4 along the first direction X and increases the total amount of ink droplets in the area to create a large amount of solvent atmosphere to improve the uneven thickness of the display pixels 121 in the second direction Y, thereby achieving the purpose of a narrow frame along the second direction Y.

[0098] In some embodiments, the thickness of the fourth lateral redundant pixel 125 is greater than the thickness of the third lateral redundant pixel 124. Thus, the total amount of ink droplets required to form the fourth lateral redundant pixel 125 can be greater than the total amount of ink droplets required to form the third lateral redundant pixel 124, further reducing the volatilization rate of the solvent in the fourth lateral redundant pixel region 11B4, further improving the uneven thickness of the display pixel 121 along the second direction Y, and thus facilitating a reduction in the size of the non-display area 11B along the second direction Y.

[0099] In some embodiments, the thickness of the fourth lateral redundant pixel 125 is greater than the thickness of the second lateral redundant pixel 123. Thus, the total number of ink droplets required to form the fourth lateral redundant pixel 125 can be greater than the total number of ink droplets required to form the second lateral redundant pixel 123, further reducing the volatilization rate of the solvent in the fourth lateral redundant pixel region 11B4. This further improves the uneven thickness of the display pixel 121 along the second direction Y, thereby facilitating a reduction in the size of the non-display area 11B along the second direction Y.

[0100] In some embodiments, the thickness of the corner redundant pixel 126 is greater than the thickness of the fourth lateral redundant pixel 125. Thus, the total number of ink droplets required to form the corner redundant pixel 126 can be greater than the total number of ink droplets required to form the fourth lateral redundant pixel 125, further reducing the evaporation rate of the solvent in the corner redundant pixel region 11B5, further improving the uneven thickness of the display pixels 121 at the corners of the display area 11A along the second direction Y, and reducing the size of the non-display area 11B.

[0101] In some embodiments, the area of ​​a fourth lateral redundant pixel 125 is larger than the areas of the third lateral redundant pixel 124 and the second lateral redundant pixel 123. Thus, the total number of ink droplets required to form the fourth lateral redundant pixel 125 can be greater than the total number of ink droplets required to form the third lateral redundant pixel 124 and the total number of ink droplets required to form the second lateral redundant pixel 123, further reducing the volatilization rate of the solvent in the fourth lateral redundant pixel region 11B4. This further improves the uneven thickness of the display pixels 121 along the second direction Y, thereby facilitating a reduction in the size of the non-display area 11B along the second direction Y.

[0102] In some embodiments, a fourth lateral redundant pixel 125 extends along the first direction X to both ends of the fourth lateral redundant pixel 125, respectively adjacent to two corner redundant pixel regions 11B5. Thus, the fourth lateral redundant pixel 125 is larger in size, which helps increase the area of ​​the fourth lateral redundant pixel 125 and increases the total amount of ink droplets required to form the fourth lateral redundant pixel 125.

[0103] In some embodiments, in a fourth lateral redundant pixel region 11B4, the number of the fourth lateral redundant pixels 125 may be one or more. Figure 2 and Figure 3 As shown, in a fourth lateral redundant pixel region 11B4 , a plurality of fourth lateral redundant pixels 125 are arranged at intervals along the second direction Y. The sizes of the plurality of fourth lateral redundant pixels 125 along the second direction Y may be the same or different.

[0104] In some embodiments, the fourth lateral redundant pixels 125 are strip-shaped, which allows the fourth lateral redundant pixels 125 to fully utilize the space lateral to the display area 11A and simplifies the formation of the fourth lateral redundant pixels 125 .

[0105] In some embodiments, the fourth lateral redundant pixel 125 includes a first edge L1 at its end in the first direction X, extending along the second direction Y. The first lateral redundant pixel 122 has a second edge L2 adjacent to the second lateral redundant pixel 123 and extending along the second direction Y. The second edge L2 is aligned with the first edge L1. In this manner, the fourth lateral redundant pixel 125 can also alleviate the uneven thickness problem of the first lateral redundant pixel 122 along the second direction Y.

[0106] In some embodiments, display pixel 121, first to fourth lateral redundant pixels 122 to 125, and corner redundant pixel 126 may include, but are not limited to, organic light-emitting materials. The organic light-emitting material includes at least one of a red organic light-emitting material, a green organic light-emitting material, and a blue organic light-emitting material. The above-described pixels can be obtained by spraying ink droplets and then removing the solvent from the ink droplets. Spraying includes at least one of inkjet printing and coating. Exemplarily, the ink droplets are sprayed by inkjet printing.

[0107] In some embodiments, see Figure 4 As shown, the display panel 100 further includes a pixel definition layer 13 , and the pixel definition layer 13 is located on the substrate 11 .

[0108] The pixel definition layer 13 includes a display area opening 131A. The display area opening 131A is located in the display area 11A. The display area dam 131 is provided around the display area opening 131A. The display pixel 121 is located in the display area opening 131A.

[0109] Pixel definition layer 13 includes a first lateral pixel opening 132A. First lateral pixel opening 132A is located in first lateral redundant pixel region 11B1. First lateral redundant pixel 122 is located in first lateral pixel opening 132A. If first lateral redundant pixel 122 is identical to display pixel 121, first lateral pixel opening 132A can be identical to display region opening 131A, i.e., have the same shape and size.

[0110] In some embodiments, the pixel definition layer 13 further includes a first lateral pixel dam 132. The first lateral pixel dam 132 is disposed around the first lateral pixel opening 132A. The thickness of the first lateral pixel dam 132 is equal to the thickness of the display area dam 131. Thus, the first lateral pixel dam 132 and the display area dam 131 can be formed using the same process, simplifying the manufacturing process of the display panel 100. Furthermore, the structure around the first lateral pixel opening 132A is identical to that around the display area opening 131A, allowing the first lateral redundant pixel 122 to better serve as a buffer during its formation.

[0111] The pixel definition layer 13 includes a second lateral pixel opening 133A. The second lateral pixel opening 133A is located in the second lateral redundant pixel region 11B2. The second lateral redundant pixels 123 are located in the second lateral pixel opening 133A. When the second lateral redundant pixels 123 extend along the first direction X, the second lateral pixel opening 133A extends along the first direction X. In a second lateral redundant pixel region 11B2, when multiple second lateral redundant pixels 123 are arranged at intervals along the second direction Y, the multiple second lateral pixel openings 133A are arranged at intervals along the second direction Y.

[0112] In some embodiments, the pixel definition layer 13 further includes a second lateral pixel dam 133. The second lateral pixel dam 133 is disposed around the second lateral pixel opening 133A. The thickness of the second lateral pixel dam 133 is greater than or equal to the thickness of the display area dam 131. This reduces the risk of ink droplets in the display area 11A flowing into the opening of the second lateral redundant pixel 123, thereby improving the thickness uniformity of the display pixels 121 in the display area 11A along the first direction X. Optionally, the thickness of the second lateral pixel dam 133 is greater than the thickness of the display area dam 131.

[0113] In some embodiments, pixel definition layer 13 includes a third lateral pixel opening (not shown). The third lateral pixel opening is located in third lateral redundant pixel region 11B3. Third lateral redundant pixel 124 is located in the third lateral pixel opening. If third lateral redundant pixel 124 is identical to display pixel 121, the third lateral pixel opening can be identical to display region opening 131A, i.e., the two have the same shape and size.

[0114] In some embodiments, the pixel definition layer 13 further includes a third lateral pixel dam (not shown). The third lateral pixel dam is disposed around the third lateral pixel opening. The thickness of the third lateral pixel dam is equal to the thickness of the display area dam 131. Thus, the third lateral pixel dam and the display area dam 131 can be formed using the same process, simplifying the manufacturing process of the display panel 100. Furthermore, the structure surrounding the third lateral pixel opening is identical to that surrounding the display area opening 131A, allowing the third lateral redundant pixel 124 to better serve as a buffer during its formation.

[0115] The pixel definition layer 13 includes a fourth lateral pixel opening (not shown). The fourth lateral pixel opening is located in the fourth lateral redundant pixel region 11B4. The fourth lateral redundant pixel 125 is located in the fourth lateral pixel opening. When the fourth lateral redundant pixel 125 extends along the first direction X, the fourth lateral pixel opening extends along the first direction X. In a fourth lateral redundant pixel region 11B4, when multiple fourth lateral redundant pixels 125 are arranged at intervals along the second direction Y, the multiple fourth lateral pixel openings are arranged at intervals along the second direction Y.

[0116] In some embodiments, the pixel definition layer 13 further includes a fourth lateral pixel dam (not shown). The fourth lateral pixel dam is disposed around the fourth lateral pixel opening. The thickness of the fourth lateral pixel dam is greater than or equal to the thickness of the display area dam 131. This reduces the risk of ink droplets in the display area 11A flowing into the fourth lateral pixel opening, thereby improving the thickness uniformity of the display pixels 121 in the display area 11A along the second direction Y. Optionally, the thickness of the fourth lateral pixel dam is greater than the thickness of the display area dam 131.

[0117] The pixel definition layer 13 includes a corner redundant pixel opening (not shown). The corner redundant pixel opening is located in the corner redundant pixel region 11B5. The corner redundant pixel 126 is located in the corner redundant pixel opening. If the corner redundant pixel 126 is in a stripe shape, the corner redundant pixel opening is also in a stripe shape.

[0118] In some embodiments, the pixel definition layer 13 further includes a corner redundant pixel dam (not shown). The corner redundant pixel dam is disposed around the corner redundant pixel opening. The thickness of the corner redundant pixel dam is greater than or equal to the thickness of the display area dam 131. This reduces the risk of ink droplets in the display area 11A flowing into the corner redundant pixel opening, thereby improving the thickness uniformity of the display pixels 121 at the corners of the display area 11A. Optionally, the thickness of the corner redundant pixel dam is greater than the thickness of the display area dam 131.

[0119] In some embodiments, as Figure 4As shown, the display panel 100 further includes an anode layer 141 and a cathode layer 142 , and the pixel definition layer 13 is located between the anode layer 141 and the cathode layer 142 .

[0120] In some embodiments, as Figure 4 As shown, the display panel 100 further includes a driving circuit layer 143 . The driving circuit layer 143 is located between the substrate 11 and the anode layer 141 . The driving circuit layer 143 includes a pixel driving circuit connected to the anodes in the anode layer 141 .

[0121] like Figure 5 As shown in (A) to (D), Figure 5 (A) is a schematic diagram of printing ink drops when forming the display pixel 121, the first lateral redundant pixel 122 and the third lateral redundant pixel 124. Figure 5 Middle (B) is a schematic diagram of printing ink droplets when forming the second lateral redundant pixel 123, Figure 5 Middle (C) is a schematic diagram of printing ink drops when forming the fourth lateral redundant pixel 125, Figure 5 Middle (D) is a schematic diagram of printing ink droplets when forming the corner redundant pixel 126.

[0122] Combine Figure 5 As can be seen from (A) to (D), the number and density of ink droplets printed when forming display pixel 121, first lateral redundant pixel 122, and third lateral redundant pixel 124 are the same. The number and density of ink droplets printed when forming second lateral redundant pixel 123, fourth lateral redundant pixel 125, and corner redundant pixel 126 are greater than the number and density of ink droplets printed when forming display pixel 121.
