Abstract
Description
Display panel and display device Technical Field
[0001] This application relates to the field of display technology, and more particularly to a display panel and display device. Background Technology
[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-illumination, wide viewing angle, high contrast, low power consumption, extremely fast response speed, ultra-lightweight and thin design, flexible display, rollable screen, strong temperature adaptability, and simple manufacturing process. The method of fabricating corresponding devices using inkjet printing (IJP) has attracted much attention due to its high material utilization rate. However, when using inkjet printing to fabricate display devices, in order to ensure the uniformity of film formation in the display area and the uniformity of brightness of the light-emitting device, in addition to printing the light-emitting material in the display area, virtual pixels are generally printed around the display area using the same material to ensure the uniformity of film formation in the display area. However, setting a large number of virtual pixels results in a larger bezel on the display panel. Invention Overview
[0003] This application provides a display panel and a display device to reduce the bezel of the display panel, thereby at least partially solving the above-mentioned technical problems.
[0004] To achieve the above objectives, according to a first aspect of this application, a display panel is provided, comprising:
[0005] A substrate has a display area and a non-display area surrounding the display area. The non-display area includes a first lateral redundant pixel area and a second lateral redundant pixel area. The second lateral redundant pixel area is located on at least one side of the display area in a first direction, and the first lateral redundant pixel area is located between the second lateral redundant pixel area and the display area.
[0006] Multiple display pixels are located on the substrate of the display area;
[0007] A first lateral redundant pixel is located on the substrate of the first lateral redundant pixel region, and the area of the first lateral redundant pixel is the same as the area of at least one of the display pixels.
[0008] Multiple second lateral redundant pixels, extending along the first direction and spaced apart along the second direction, are located on the substrate of a second lateral redundant pixel region. The size of a second lateral redundant pixel along the first direction is greater than the 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 this application, a display device is provided, the display device including the above-described display panel. Beneficial effects
[0010] In the display panel and display device of this application embodiment, the area of the first lateral redundant pixel is the same as the area of at least one display pixel. Therefore, the total amount of ink droplets required to form the first lateral redundant pixel is the same as the total amount of ink droplets required to form at least one display pixel. The first lateral redundant pixel area is located at the edge of the display area. After the ink droplets dry, the edge of the uneven film thickness will first be located in the first lateral redundant pixel area, that is, the first lateral redundant pixel plays a buffering role for the uneven thickness of the display pixels in the first direction of the display area.
[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 larger 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 includes more solvent, reducing the evaporation rate of the solvent in the second lateral redundant pixel area. The evaporation rate of the solvent in the outer second lateral redundant pixel area tends to be the same as the smaller evaporation rate of the solvent in the inner display area, reducing the risk of ink flowing from the display area to the non-display area along the first direction. Thus, the problem of uneven thickness of the display pixels in the display area along the first direction is also improved, which is beneficial to reducing 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 technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.
[0026] Please refer to Figures 1 to 4. This application embodiment provides a display panel 100. The display panel 100 can be at least one of an organic light-emitting diode (OLED) display panel and a quantum dot display panel. In one exemplary embodiment, the display panel 100 is an organic light-emitting diode (OLED) 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 also includes a plurality of display pixels 121. The plurality of display pixels 121 are located on the substrate 11 of the display area 11A.
[0030] In some embodiments, the plurality of display pixels 121 includes a plurality of display pixel rows 121A. A 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 located in adjacent display pixel rows 121A emit light of different colors. The second direction Y intersects the first direction X.
[0031] In one 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. An adjacent first display pixel row, a second display pixel row, and a third display pixel row are arranged repeatedly 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, second, and third display pixels emit three different colors of light, such as red, blue, 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. A polygon includes at least one of a square, a rhombus, a pentagon, a hexagon, and an octagon. In one exemplary embodiment, the shape of the display pixel 121 is rectangular.
[0033] In one exemplary embodiment, the first direction X is perpendicular to the second direction Y, but this is not a limitation. The angle between the first direction X and the second direction Y can also be an acute angle or an obtuse angle.
[0034] In some embodiments, as shown in FIG1, 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] Please refer to Figure 1. 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, referring to FIG1, along the first direction X, the display region 11A is located between the two first lateral redundant pixel regions 11B1, that is, the two first lateral redundant pixel regions 11B1 are located at the outer edge of the display region 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 larger 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 it is not limited thereto.
[0038] In some embodiments, referring to Figures 1 to 3, the display panel 100 further includes a first lateral redundant pixel 122. The first lateral redundant pixel 122 is located on the substrate 11 of the first lateral redundant pixel region 11B1.
[0039] The area of the first lateral redundant pixel 122 is the same as the area of at least one display pixel 121. Therefore, the total amount of ink droplets required to form the first lateral redundant pixel 122 is similar to the total amount of ink droplets required to form at least one display pixel 121. The first lateral redundant pixel region 11B1 is located at the edge of the display region 11A in the first direction X. After the ink droplets dry, the uneven film thickness edges will first be located in the first lateral redundant pixel region 11B1. That is, the first lateral redundant pixel 122 in the first lateral redundant pixel region 11B1 acts as a buffer against the uneven thickness of the display pixels 121 in the first direction X of the display region 11A.
[0040] In some embodiments, the shape of the first lateral redundant pixel 122 is the same as the shape of at least one display pixel 121. This makes it advantageous that the area of the first lateral redundant pixel 122 is the same as the area of at least one display pixel 121. Exemplarily, in one exemplary embodiment, the shape of both the first lateral redundant pixel 122 and the display pixel 121 is rectangular, but this is not a limitation. In one exemplary embodiment, the shape of both the first lateral redundant pixel 122 and the display pixel 121 may be circular or elliptical, etc.
[0041] In some embodiments, when the shape of the first lateral redundant pixel 122 is the same as the shape of 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 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 one display pixel 121 along the second direction Y. This makes it advantageous for the area of the first lateral redundant pixel 122 to be the same as or nearly the same as the area of at least one display pixel 121.
[0042] It should be noted that, in this 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, respectively. 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 at least one display pixel 121. Thus, the total amount of ink droplets forming the first lateral redundant pixel 122 can be the same as the total amount of ink droplets forming at least one display pixel 121, and the formation process of the first lateral redundant pixel 122 buffers the uneven thickness of the display pixels 121 in the first direction X of the display area 11A.
[0044] In some embodiments, referring to Figures 2 and 3, 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 more first lateral redundant pixels 122 along the first direction X, the better the buffering effect of the first lateral redundant pixel region 11B1 on the uneven thickness of the display pixels 121 of the display area 11A in the first direction X. Conversely, the fewer first lateral redundant pixels 122 along the first direction X, the smaller the size occupied by the first lateral redundant pixel region 11B1 in the first direction X, thus 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 the number of first lateral redundant pixels 122 outside the display area 11A that is similar to the display pixel 121 is appropriate. In this way, while reserving a portion of the first lateral redundant pixels 122 to serve as a buffer in the first direction X, it also reduces the space occupied by the first lateral redundant pixel area 11B1 in the first direction X, providing formation space for the second lateral redundant pixels 123 described below.
[0046] In an exemplary embodiment, referring to Figures 2 and 3, in a first lateral redundant pixel region 11B1, the number of first lateral redundant pixels 122 along the first direction X is 1.
[0047] In another exemplary embodiment, in a first lateral redundant pixel region 11B1, the number of first lateral redundant pixels 122 along the first direction X is 3.
[0048] In some embodiments, when the plurality of display pixels 121 include a plurality of display pixel rows 121A spaced apart along the second direction Y, a plurality of first lateral redundant pixels 122 spaced apart along the second direction Y are provided in a first lateral redundant pixel region 11B1, and at least two display pixels 121 and at least one first lateral redundant pixel 122 of a display pixel row 121A are arranged side by side along the first direction X. This simplifies the formation process of 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 arranged side by side comprise the same material. This allows the first lateral redundant pixels 122 and the display pixels 121 to be continuously formed using the same ink droplets, simplifying their formation process.
[0050] Referring to Figure 1, the second lateral redundant pixel region 11B2 is located on at least one side of the display area 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 area 11A. Thus, the second lateral redundant pixel region 11B2 can be located on 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 larger 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 also reduced.
[0052] In an exemplary embodiment, along the first direction X, two second lateral redundant pixel regions 11B2 are located on opposite sides of the display area 11A.
[0053] Referring to Figures 2 and 3, the display panel 100 also includes a plurality of second lateral redundant pixels 123. The plurality of second lateral redundant pixels 123 extend along a first direction X and are spaced apart along a second direction Y, and are located on a substrate 11 of a second lateral redundant pixel region 11B2. The dimension XC2 of a second lateral redundant pixel 123 along the first direction X is larger than the 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 the second lateral redundant pixel 123 is greater than the number of ink droplets required to form at least one first lateral redundant pixel 122. The larger number of ink droplets includes more solvent, 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 smaller evaporation rate of the solvent in the inner display region 11A, reducing the risk of ink in the display region 11A flowing from the display region 11A to the non-display region 11B along the first direction X. Thus, the problem of uneven thickness of the display pixels 121 in the display area 11A along the first direction X is also improved, which helps to reduce 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, in this embodiment of the application, the thickness unevenness of the display pixels 121 in the first direction X is improved by compressing the size of the second lateral redundant pixel area 11B2 along the first direction X and increasing the total amount of ink droplets in the area to create a large solvent atmosphere, thereby achieving the purpose of a narrow bezel along the first direction X.
[0055] In some embodiments, the ratio of the dimension XC2 of a 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 is greater than or equal to 2. Thus, forming the second lateral redundant pixel 123 along the first direction X requires a larger number of ink droplets, which includes more solvent, further reducing the solvent evaporation rate in the second lateral redundant pixel region 11B2.
[0056] In some embodiments, the ratio of the size XC2 of a second lateral redundant pixel 123 along the first direction X to the size XC1 of at least one first lateral redundant pixel 122 along the first direction X is less than or equal to 15. This reduces the size occupied by the second lateral redundant pixel 123 along the first direction X, and reduces the size of the non-display area 11B along the first direction X.
[0057] Optionally, the ratio of the size XC2 of the second lateral redundant pixel 123 along the first direction X to the size XC1 of at least one first lateral redundant pixel 122 along the first direction X can be 3~12, 3~8, or 5~15. In this way, while improving the problem of uneven thickness of the display pixel 121 along the first direction X, the size of the non-display area 11B along the first direction X is also reduced.
[0058] It is understood that the ratio of the size XC2 of a second lateral redundant pixel 123 along the first direction X to the size XC1 of at least one first lateral redundant pixel 122 along the first direction X can be any value between 2 and 15. For example, 2, 3, 5, 7, 9, 11, 13, or 15.
[0059] In some embodiments, referring to Figures 2 and 3, a second lateral redundant pixel 123 extends along a first direction X to its opposite ends, adjacent to the edges of the first lateral redundant pixel region 11B1 and the non-display region 11B, respectively. Thus, the size XC2 of the second lateral redundant pixel 123 along the first direction X is larger, resulting in a larger area. A greater total amount of ink droplets is required to form the second lateral redundant pixel 123, further reducing the solvent evaporation rate in the second lateral redundant pixel region 11B2. Furthermore, the number of second lateral redundant pixels 123 along the first direction X is one, achieving the purpose of a narrow bezel in the display panel 100.
[0060] In other embodiments, the number of second lateral redundant pixels 123 along the first direction X may also be two or more, improving the design flexibility of the second lateral redundant pixels 123, thereby improving the flexibility of realizing the narrow bezel display panel 100.
[0061] In some embodiments, referring to FIG2, when the size XC2 of a second lateral redundant pixel 123 along the first direction X is greater than the size XC1 of at least one first lateral redundant pixel 122 along the first direction X, the size YC2 of a second lateral redundant pixel 123 along the second direction Y can be equal to the size YC1 of at least one first lateral redundant pixel 122 along the second direction Y. Thus, 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 smaller evaporation rate of the solvent in the inner display region 11A, reducing the risk of ink in the display region 11A flowing from the display region 11A to the non-display region 11B along the first direction X. Thus, the problem of uneven thickness of the display pixels 121 in the display area 11A along the first direction X is also improved, which helps to reduce 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, referring to FIG2, when the size YC2 of a second lateral redundant pixel 123 along the second direction Y is equal to the size 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 pixel 123 and the first lateral redundant pixel 122. Furthermore, when the first lateral redundant pixel 122 is arranged side-by-side with the display pixel row 121A along the first direction X, the second lateral redundant pixel 123 can better improve the problem of uneven thickness of the display pixel 121 along the first direction X.
[0063] In some embodiments, referring to FIG3, when the size XC2 of a second lateral redundant pixel 123 along the first direction X is greater than the size XC1 of at least one first lateral redundant pixel 122 along the first direction X, the size YC2 of a second lateral redundant pixel 123 along the second direction Y can also be greater than the size YC1 of a first lateral redundant pixel 122 along the second direction Y. Thus, 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 other embodiments, the ratio of the dimension YC2 of a second lateral redundant pixel 123 along the second direction Y to the 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 may be equal to the number of rows of display pixel row 121A along the second direction Y.
[0065] Optionally, the ratio of the dimension YC2 of a second lateral redundant pixel 123 along the second direction Y to the dimension YC1 of a first lateral redundant pixel 122 along the second direction Y can be greater than or equal to 2 and less than or equal to 50. Optionally, the ratio of the dimension YC2 of a second lateral redundant pixel 123 along the second direction Y to the dimension YC1 of a first lateral redundant pixel 122 along the second direction Y can be 3~30, 4~25, 5~20, or 6~15.
[0066] In other embodiments, when the size YC2 of a second lateral redundant pixel 123 along the second direction Y is greater than or equal to the size 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 can be arranged side by side with a second lateral redundant pixel 123 along the first direction X.
[0067] In one exemplary embodiment, referring to FIG3, two adjacent first lateral redundant pixels 122 arranged side by side along the second direction Y can be arranged side by side with a 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 can be arranged side by side with a 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 display pixel row to the third display pixel row).
[0069] In yet another exemplary embodiment, six adjacent first lateral redundant pixels 122 arranged side-by-side along the second direction Y can be arranged side-by-side with a 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 sets of first display pixel rows to third display pixel rows).
[0070] In some embodiments, the second lateral redundant pixel 123 can be a strip structure extending along the first direction X. The strip structure design allows the second lateral redundant pixel 123 to make fuller use of the space in the non-display area 11B in the first direction X, while also simplifying the formation of the second lateral redundant pixel 123.
[0071] In some embodiments, along the second direction Y, the distance between two adjacent second lateral redundant pixels 123 can be equal to the distance between two adjacent display pixel rows 121A. In some embodiments, along the second direction Y, the distance between two adjacent second lateral redundant pixels 123 is equal to the spacing 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 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.
[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. Thus, 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 also includes a corner redundant pixel area 11B5. The corner redundant pixel area 11B5 is located at the corner of the non-display area 11B and is adjacent to the second lateral redundant pixel area 11B2. Referring to Figures 2 and 3, the four corner redundant pixel areas 11B5 are 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. The corner redundant pixels 126 are located in the corner redundant pixel region 11B5, and the thickness of the 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 amount of ink droplets required to form the corner redundant pixels 126 is greater than or equal to the total amount 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 the corner redundant pixels 126 provides a solvent atmosphere for the drying process of the ink droplets in the corner redundant pixel region 11B5, reducing the evaporation rate of the solvent in the corner redundant pixel region 11B5. The evaporation rate of the solvent in the corner redundant pixel region 11B5 located at the corner tends to be the same as the evaporation rate of the solvent at the corner of the display area 11A, reducing the risk of ink flowing from the corner of the display area 11A to the corner of the non-display area 11B. In this way, the problem of uneven thickness of the display pixels 121 at the corner of the display area 11A due to ink flowing to the corner of the non-display area 11B is improved, which helps to reduce the size of the corner redundant pixel area 11B5 in the non-display area 11B and further reduce the bezel of the display panel 100.
[0076] It should be noted that in related technologies, when ink printing is used to form display pixels, severe unevenness in display areas occurs at the corners. In some embodiments of this application, the aforementioned redundant corner pixels 126 are added to the non-display area 11B, which can significantly improve the uneven thickness problem of display pixels 121 at the corners of display area 11A, thereby improving the unevenness in display areas at the corners of 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 problem of uneven thickness of the display pixels 121 at the corner 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 better reduce the evaporation rate of the solvent at the corner of the non-display area 11B, and improve the problem of uneven thickness of the display pixels 121 at the corner 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 better reduce the evaporation rate of the solvent at the corner of the non-display area 11B, and improve the problem of uneven thickness of the display pixel 121 at the corner in the display area 11A.
[0080] In some embodiments, the dimension XZ1 of the corner redundant pixel 126 along the first direction X is equal to the dimension XC2 of the second lateral redundant pixel 123 along the first direction X, and the dimension YZ1 of the corner redundant pixel 126 along the second direction Y is greater than the 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 to be adjacent to the edges of the second lateral redundant pixel area 11B2 and the non-display area 11B at its opposite ends. Thus, the corner redundant pixel 126 is large enough along the second direction Y to increase its area.
[0082] Referring to Figures 2 and 3, 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, referring to Figures 2 and 3, the corner redundant pixel 126 is strip-shaped. For example, the corner redundant pixel 126 is rectangular. This strip design allows the corner redundant pixel 126 to make better use of the space at the corner of the non-display area 11B while also simplifying the formation of the corner redundant pixel 126. In some embodiments, the corner redundant pixel 126 can also be other shapes, such as L-shaped.
[0084] In some embodiments, the number of corner redundant pixels 126 in a corner redundant pixel area 11B5 can be one or more. In an exemplary embodiment, referring to Figures 2 and 3, the number of corner redundant pixels 126 in a corner redundant pixel area 11B5 can be one.
[0085] In a corner redundant pixel area 11B5, multiple corner redundant pixels 126 can be arranged at intervals along at least one of the first direction X and the second direction Y. The areas of the multiple corner redundant pixels 126 can be the same or different.
[0086] Referring to Figure 1, the non-display area 11B also includes a third lateral redundant pixel area 11B3. Along the second direction Y, the third lateral redundant pixel area 11B3 is adjacent to the display area 11A. In the first direction X, the third lateral redundant pixel area 11B3 extends along the first direction X and is located between two second lateral redundant pixel areas 11B2.
[0087] In one exemplary embodiment, along the second direction Y, the display area 11A is located between two third lateral redundant pixel areas 11B3.
[0088] Referring to Figures 2 and 3, the display panel 100 also includes a third lateral redundant pixel 124. The third lateral redundant pixel 124 is located on the substrate 11 of the 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. Thus, the total amount of ink droplets required to form the third lateral redundant pixel 124 is the same as the total amount 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 region 11A in the second direction Y. After the ink droplets dry, the edge of the uneven film thickness will first be located in the third lateral redundant pixel region 11B3. That is, the third lateral redundant pixel 124 in the third lateral redundant pixel region 11B3 plays a buffering role against the uneven thickness of the display pixels 121 of the display region 11A in the second direction Y.
[0089] In some embodiments, the shape of the third lateral redundant pixel 124 is the same as the shape of at least one display pixel 121. This makes it advantageous for the area of the third lateral redundant pixel 124 to be the same as the area 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. This makes it advantageous for the area of the third lateral redundant pixel 124 to be the same as the area of 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 at least one display pixel 121. Thus, the total amount of ink droplets forming the third lateral redundant pixel 124 can be the same as the total amount of ink droplets forming at least one display pixel 121, and the formation process of the third lateral redundant pixel 124 buffers the uneven thickness of the display pixels 121 in the first direction X of the display area 11A.
[0092] In some embodiments, referring to Figures 2 and 3, the number of third lateral redundant pixels 124 along the second direction Y in a third lateral redundant pixel region 11B3 is N, where N is greater than M. When the plurality of display pixels 121 include multiple different display pixel rows 121A (e.g., from the first display pixel row to the third display pixel row) spaced apart along the second direction Y, the number and design of the third lateral redundant pixels 124 along the second direction Y in the third lateral redundant pixel region 11B3 are related to the number and design of the 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 the 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 the first lateral redundant pixel region 11B1 is typically 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 accommodate the buffering effect of multiple different display pixel rows 121A (e.g., the first display pixel row to the third display pixel row) arranged at intervals along the second direction Y on the third lateral redundant pixel 124.
[0093] In one exemplary embodiment, when the plurality of display pixel rows 121A include the aforementioned first to third display pixel rows, the plurality of third lateral redundant pixels 124 also include first, second, and third redundant pixel rows arranged at intervals along the second direction Y. The first redundant pixel row includes a first type of redundant pixels, which are the same as the first display pixels. The second redundant pixel row includes a second type of redundant pixels, which are the same as the second display pixels. The third redundant pixel row includes a third type of redundant pixels, which are the same as the third display pixels. The arrangement direction of the first, second, and third redundant pixel rows is the same as the arrangement of 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 a display pixel row 121A in a one-to-one manner.
[0095] Referring to Figure 1, the non-display area 11B also includes a fourth lateral redundant pixel area 11B4. The fourth lateral redundant pixel area 11B4 is located on at least one side of the display area 11A in the second direction Y, and the third lateral redundant pixel area 11B3 is located between the fourth lateral redundant pixel area 11B4 and the display area 11A.
[0096] Referring to Figures 2 and 3, the display panel 100 also includes a fourth lateral redundant pixel 125. The fourth lateral redundant pixel 125 is located on the substrate 11 of the fourth lateral redundant pixel region 11B4, and 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, 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 smaller evaporation rate of the solvent in the inner display region 11A, reducing the risk of ink in the display region 11A flowing from the display region 11A to the non-display region 11B along the second direction Y. In this way, the problem of uneven thickness of the display pixels 121 in the display area 11A along the second direction Y is also improved, which helps to reduce 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, in this embodiment of the application, the thickness unevenness of the display pixels 121 in the second direction Y is improved by compressing the size of the fourth lateral redundant pixel area 11B4 along the first direction X and increasing the total amount of ink droplets in the area to create a large solvent atmosphere, thereby achieving the purpose of a narrow bezel 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 solvent evaporation rate in the fourth lateral redundant pixel region 11B4, and better improving the thickness unevenness of the display pixel 121 along the second direction Y, thereby facilitating a reduction in the size of the non-display region 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 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 second lateral redundant pixel 123, further reducing the solvent evaporation rate in the fourth lateral redundant pixel region 11B4. This better improves the problem of uneven thickness of the display pixel 121 along the second direction Y, thereby facilitating a reduction in the size of the non-display region 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 amount of ink droplets required to form the corner redundant pixel 126 can be greater than the total amount of ink droplets required to form the fourth lateral redundant pixel 125, further reducing the solvent evaporation rate in the corner redundant pixel region 11B5, better improving the uneven thickness problem of the display pixel 121 at the corner in the display region 11A along the second direction Y, and reducing the size of the non-display region 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 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 and the second lateral redundant pixel 123, further reducing the solvent evaporation rate in the fourth lateral redundant pixel region 11B4. This better improves the uneven thickness problem of the display pixel 121 along the second direction Y, thereby facilitating a reduction in the size of the non-display region 11B along the second direction Y.
[0102] In some embodiments, a fourth lateral redundant pixel 125 extends along the first direction X to its two ends, which are adjacent to two corner redundant pixel regions 11B5 respectively. Thus, the fourth lateral redundant pixel 125 has a larger size, which is beneficial for increasing the area of the fourth lateral redundant pixel 125, resulting in a larger total amount of ink droplets required to form the fourth lateral redundant pixel 125.
[0103] In some embodiments, the number of fourth lateral redundant pixels 125 in a fourth lateral redundant pixel region 11B4 can be one or more. Referring to Figures 2 and 3, 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 dimensions of the plurality of fourth lateral redundant pixels 125 along the second direction Y can be the same or different.
[0104] In some embodiments, the fourth lateral redundant pixel 125 is strip-shaped. The strip design allows the fourth lateral redundant pixel 125 to make fuller use of the lateral space of the display area 11A while also simplifying the formation of the fourth lateral redundant pixel 125.
[0105] In some embodiments, the end of the fourth lateral redundant pixel 125 in the first direction X includes a first edge L1 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 being aligned with the first edge L1. Thus, the fourth lateral redundant pixel 125 can also improve the problem of uneven thickness of the first lateral redundant pixel 122 along the second direction Y.
[0106] In some embodiments, display pixel 121, first lateral redundant pixels 122 to fourth lateral redundant pixels 125, and corner redundant pixel 126 may include, but are not limited to, organic light-emitting materials. Organic light-emitting materials include at least one of red, green, and blue organic light-emitting materials. The aforementioned 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, ink droplets are sprayed by inkjet printing.
[0107] In some embodiments, as shown in FIG4, the display panel 100 further includes a pixel definition layer 13, which 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, and the display area dam 131 is arranged around the display area opening 131A. The display pixel 121 is located in the display area opening 131A.
[0109] The pixel definition layer 13 includes a first lateral pixel opening 132A. The first lateral pixel opening 132A is located in a first lateral redundant pixel area 11B1. A first lateral redundant pixel 122 is located in the first lateral pixel opening 132A. When the first lateral redundant pixel 122 is the same as the display pixel 121, the first lateral pixel opening 132A can be the same as the display area opening 131A, that is, the two 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 a 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, since the structure around the first lateral pixel opening 132A is the same as that around the display area opening 131A, the first lateral redundant pixel 122 can better play a buffering role 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 a second lateral redundant pixel region 11B2. Second lateral redundant pixels 123 are located in the second lateral pixel opening 133A. When the second lateral redundant pixels 123 extend along a 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 a second direction Y, 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 flowing into the second lateral redundant pixel 123 opening in the display area 11A, and improves 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, the pixel definition layer 13 includes a third lateral pixel opening (not shown in the figure). The third lateral pixel opening is located in the third lateral redundant pixel area 11B3. The third lateral redundant pixel 124 is located in the third lateral pixel opening. When the third lateral redundant pixel 124 is the same as the display pixel 121, the third lateral pixel opening can be the same as the display area opening 131A, that is, 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 in the figure). 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, since the structure around the third lateral pixel opening is the same as that around the display area opening 131A, the third lateral redundant pixel 124 can better serve as a buffer during its formation.
[0115] Pixel definition layer 13 includes a fourth lateral pixel opening (not shown in the figure). The fourth lateral pixel opening is located in a fourth lateral redundant pixel region 11B4. A fourth lateral redundant pixel 125 is located in the fourth lateral pixel opening. When the fourth lateral redundant pixel 125 extends along a 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 a second direction Y, 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 flowing into the fourth lateral pixel opening in the display area 11A and improves 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] Pixel definition layer 13 includes corner redundant pixel openings (not shown in the figure). The corner redundant pixel openings are located in corner redundant pixel area 11B5. Corner redundant pixel 126 is located within the corner redundant pixel opening. When the corner redundant pixel 126 is strip-shaped, the corner redundant pixel opening is also strip-shaped.
[0118] In some embodiments, the pixel definition layer 13 further includes a corner redundant pixel dam (not shown in the figure). 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. In this way, the risk of ink droplets flowing into the corner redundant pixel opening in the display area 11A is reduced, and the thickness uniformity of the display pixels 121 at the corners in the display area 11A is improved. 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 shown in FIG4, the display panel 100 further includes an anode layer 141 and a cathode layer 142, and a pixel definition layer 13 is located between the anode layer 141 and the cathode layer 142.
[0120] In some embodiments, as shown in FIG4, 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 anode in the anode layer 141.
[0121] As shown in Figures 5(A) to (D), Figure 5(A) is a schematic diagram of printing ink droplets when forming display pixel 121, first lateral redundant pixel 122 and third lateral redundant pixel 124, Figure 5(B) is a schematic diagram of printing ink droplets when forming second lateral redundant pixel 123, Figure 5(C) is a schematic diagram of printing ink droplets when forming fourth lateral redundant pixel 125, and Figure 5(D) is a schematic diagram of printing ink droplets when forming corner redundant pixel 126.
[0122] As shown in Figures 5(A) to (D), the number and density of printed ink droplets are the same when forming display pixel 121, the first lateral redundant pixel 122, and the third lateral redundant pixel 124. The number and density of printed ink droplets are greater when forming the second lateral redundant pixel 123, the fourth lateral redundant pixel 125, and the corner redundant pixel 126 than when forming display pixel 121.
