Abstract
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, soft display, rollable screen, strong temperature adaptability, and simple manufacturing process. The method of preparing corresponding devices using inkjet printing (ink-jet printing, IJP) 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] The embodiments of the present application provide a display panel and a display device to reduce the frame of the display panel, so as to at least partially solve the above technical problems.
[0004] In order to achieve the above object, 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, wherein the non-display area includes a first lateral redundant pixel area and a second lateral redundant pixel area, wherein 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] 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, and are located on the substrate in a second lateral redundant pixel region, wherein 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, and the first direction intersects with 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 the display device of the embodiment 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 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 are dried, the edge with 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 display area in the first direction.
[0011] Furthermore, a plurality of second lateral redundant pixels extend along the first direction and are arranged at intervals 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. A larger number of ink droplets includes more solvent, which reduces the volatilization rate of the solvent in the second lateral redundant pixel area. The volatilization rate of the solvent in the second lateral redundant pixel area located on the outside tends to be the same as the smaller volatilization rate of the solvent in the display area on the inside, which reduces 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 the display pixels in the display area along the first direction is also improved, which is conducive 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 in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than 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 the present 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 hard substrate. The flexible substrate may include an organic substrate. The hard substrate may include a glass substrate.
[0028] The substrate 11 has a display area 11A and a non-display area 11B located around 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 include a plurality of display pixel rows 121A. One 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 one 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 respectively located in adjacent display pixel rows 121A emit light of different colors. The second direction Y intersects with 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 the second direction Y. An adjacent first display pixel row, a second display pixel row, and a third display pixel row 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 the 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 respectively emit three different colors of light, 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, 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. 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 first lateral redundant pixel region 11B1 is rectangular in shape, 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 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 are dried, the edge with uneven film thickness 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 has a buffering effect on the uneven thickness of the display pixels 121 in the display region 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 at least one display pixel 121. In this way, the area of the first lateral redundant pixel 122 is the same as the area of the at least one display pixel 121. Exemplarily, in an exemplary embodiment, the shape of the first lateral redundant pixel 122 and the shape of the display pixel 121 are both rectangular, but not limited thereto. In an exemplary embodiment, the shape of the first lateral redundant pixel 122 and the shape of the display pixel 121 can both 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 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 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. In this way, the area of the first lateral redundant pixel 122 is the same as or tends to be 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 at least one display pixel 121. In this way, 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 the at least one display pixel 121, and the formation process of the first lateral redundant pixel 122 plays a buffering role in the 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, along the first direction X, the number of the first lateral redundant pixels 122 is M, where M is a positive integer. Along the first direction X, the more the number of the first lateral redundant pixels 122 is, 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 is. Along the first direction X, the fewer the number of the first lateral redundant pixels 122 is, the smaller the size occupied by the first lateral redundant pixel region 11B1 in the first direction X is, 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 the number of first lateral redundant pixels 122 that are similar to the display pixels 121 outside the display area 11A is appropriate. In this way, while a portion of the first lateral redundant pixels 122 is reserved to play a buffering role in the first direction X, the space occupied by the first lateral redundant pixel area 11B1 in the first direction X is reduced, providing a 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 plurality of first lateral redundant pixels 122 arranged at intervals along the second direction Y are disposed in one first lateral redundant pixel region 11B1, and at least two display pixels 121 of one display pixel row 121A and at least one first lateral redundant pixel 122 are disposed side by side along the first direction X. In this way, the formation process of the display pixels 121 and the first lateral redundant pixels 122 is simplified.
[0049] In some embodiments, the first lateral redundant pixels 122 and the display pixels 121 disposed side by side include 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 is conducive to simplifying the formation process of the two.
[0050] See also Figure 1 As shown, the second lateral redundant pixel region 11B2 is located 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. Thus, the second lateral redundant pixel region 11B2 may 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 region 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 also Figure 2 and Figure 3As shown, the display panel 100 further includes a plurality of second lateral redundant pixels 123. The plurality of second lateral redundant pixels 123 extend along the first direction X and are arranged at intervals along the second direction Y, and are located on the substrate 11 of a second lateral redundant pixel area 11B2. 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. 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. A larger number of ink droplets includes more solvent, which reduces the volatilization rate of the solvent in the second lateral redundant pixel area 11B2. The volatilization rate of the solvent in the second lateral redundant pixel area 11B2 located on the outside tends to be the same as the smaller volatilization rate of the solvent in the display area 11A on the inside, which reduces the risk of the 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 beneficial 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 the 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 size XC2 of a 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 greater than or equal to 2. Thus, along the first direction X, a larger number of ink droplets is required to form the second lateral redundant pixel 123, and a larger number of ink droplets includes more solvent, further reducing the volatilization rate of the solvent in the second lateral redundant pixel area 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, 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 may be 3 to 12, 3 to 8, or 5 to 15. In this way, while improving the uneven thickness problem 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 understandable 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, 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 the opposite ends of the second lateral redundant pixel 123, respectively adjacent to the edges of the first lateral redundant pixel area 11B1 and the non-display area 11B. In this way, the size XC2 of the second lateral redundant pixel 123 along the first direction X is larger, so that the area of the second lateral redundant pixel 123 is larger. The total amount of ink droplets required to form the second lateral redundant pixel 123 is more, further reducing the volatilization rate of the solvent in the second lateral redundant pixel area 11B2. In addition, along the first direction X, the number of the second lateral redundant pixel 123 is one, so as to achieve the purpose of having a narrow frame of the display panel 100.
[0060] In some other embodiments, along the first direction X, the number of the second lateral redundant pixels 123 may be two or more, thereby improving the design flexibility of the second lateral redundant pixels 123 and further improving the flexibility of the display panel 100 for achieving a narrow frame.
[0061] In some embodiments, see Figure 2As shown, in the case where 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 may be equal to the size 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 volatilization rate of the solvent in the second lateral redundant pixel area 11B2. The volatilization rate of the solvent in the second lateral redundant pixel area 11B2 located on the outside tends to be the same as the smaller volatilization rate of the solvent in the display area 11A on the inside, reducing the risk of the 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 beneficial 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, in the case where 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, along the first direction X, a second lateral redundant pixel 123 can be arranged side by side with at least one first lateral redundant pixel 122 to simplify the formation process of the second lateral redundant pixel 123 and the first lateral redundant pixel 122. In addition, in the case where the first lateral redundant pixel 122 and the display pixel row 121A are arranged side by side 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 other embodiments, see Figure 3 As shown, 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 may also be greater than the size 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 size YC2 of one second lateral redundant pixel 123 along the second direction Y to a size YC1 of one 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 display pixel rows 121A along the second direction Y.
[0065] Optionally, a ratio of a size YC2 of a second lateral redundant pixel 123 along the second direction Y to a size 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 size YC2 of a second lateral redundant pixel 123 along the second direction Y to a size 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 some 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 may be arranged side by side with a 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 arranged side by side with two adjacent display pixel rows 121A (e.g., the first display pixel row and the second display pixel row), respectively.
[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 arranged side by side with three adjacent display pixel rows 121A (e.g., the first display pixel row to the third display pixel row), respectively.
[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 arranged side by side with six adjacent display pixel rows 121A (e.g., two groups of first to third display pixel rows), respectively.
[0070] In some embodiments, the second lateral redundant pixel 123 may be a stripe structure extending along the first direction X. The stripe structure design allows the second lateral redundant pixel 123 to fully utilize the space of the non-display area 11B in the first direction X and simplifies 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 may 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. In this way, 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, so as to reduce 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, and 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, so as to reduce 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 a corner redundant pixel 126. The corner redundant pixel 126 is located in the corner redundant pixel area 11B5, and the thickness of the corner redundant pixel 126 is greater than or equal to the thickness of the first lateral redundant pixel 122 and the second lateral redundant pixel 123. Therefore, the total amount of ink droplets required to form the corner redundant pixel 126 is greater than or equal to the total amount of ink droplets required to form the second lateral redundant pixel 123 and the first lateral redundant pixel 122. A large amount of solvent in the ink droplets forming the corner redundant pixel 126 provides a solvent atmosphere for the drying process of the ink droplets in the corner redundant pixel area 11B5, reducing the volatilization rate of the solvent in the corner redundant pixel area 11B5. The volatilization rate of the solvent in the corner redundant pixel area 11B5 located at the corner tends to be the same as the volatilization rate of the solvent at the corner in 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 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 beneficial 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 the related art, when ink printing is used to form display pixels, serious display unevenness problems may occur at the corners of the display area. In some embodiments of the present application, the above-mentioned corner redundant pixels 126 are added to the non-display area 11B, which can significantly improve the uneven thickness problem of the display pixels 121 at the corners of the display area 11A, thereby improving the display unevenness problem 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 problem of the display pixel 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. In this way, the total amount of ink droplets required to form the corner redundant pixel 126 is larger 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 volatilization 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 of the display area 11A.
[0079] In some embodiments, the area of a corner redundant pixel 126 is larger than the area of the display pixel 121. Thus, the total amount of ink droplets required to form the corner redundant pixel 126 is larger 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 volatilization rate of the solvent at the corner of the non-display area 11B, thereby improving the problem of uneven thickness of the display pixel 121 at the corner of 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 until two opposite ends of the corner redundant pixel 126 are respectively adjacent to the edge of the second lateral redundant pixel region 11B2 and the non-display region 11B. In this way, 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 also 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 shape of the corner redundant pixel 126 is a strip. For example, the shape of the corner redundant pixel 126 is a rectangle. In this way, the strip design allows the corner redundant pixel 126 to make full use of the space at the corner of the non-display area 11B, while also simplifying the difficulty of forming the corner redundant pixel 126. In some embodiments, the corner redundant pixel 126 can also be 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, and the areas of the plurality of corner redundant pixels 126 may be the same or different.
[0086] See also Figure 1 As shown, the non-display area 11B further includes a third lateral redundant pixel area 11B3. The third lateral redundant pixel area 11B3 is adjacent to the display area 11A along the second direction Y. In the first direction X, the third lateral redundant pixel area 11B3 extends along the first direction X and is located between the two second lateral redundant pixel areas 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 also 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 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. In this way, 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 are dried, the edge with 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 for the uneven thickness of the display pixels 121 in 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. In this way, the area of the third lateral redundant pixel 124 is advantageously 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. In this way, the area of the third lateral redundant pixel 124 is advantageously 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. In this way, 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 the at least one display pixel 121, and the formation process of the third lateral redundant pixel 124 plays a buffering role in the 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 area 11B3, the number of third lateral redundant pixels 124 along the second direction Y is N, and N is greater than M. In the case where the plurality of display pixels 121 include a plurality of 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, the number and design of the third lateral redundant pixels 124 along the second direction Y in the third lateral redundant pixel area 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 the third lateral redundant pixels 124 along the second direction Y in the third lateral redundant pixel area 11B3 needs to be greater than or equal to 3. The number of the first lateral redundant pixels 122 along the first direction X in the first lateral redundant pixel area 11B1 is generally 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 a plurality of different display pixel rows 121A (eg, the first display pixel row to the third display pixel row) arranged at intervals along the second direction Y for the third lateral redundant pixels 124 .
[0093] In an exemplary embodiment, when the plurality of display pixel rows 121A include the first to third display pixel rows, the plurality of third lateral redundant pixels 124 also include the first redundant pixel row, the second redundant pixel row, and the 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 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 directions of the first redundant pixel row, the second redundant pixel row, and the third redundant pixel row are 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 one display pixel row 121A in a one-to-one manner.
[0095] See also Figure 1As shown, the non-display area 11B further includes a fourth lateral redundant pixel area 11B4 located at least on 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 also 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 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 volatilization rate of the solvent in the fourth lateral redundant pixel region 11B4. The volatilization rate of the solvent in the fourth lateral redundant pixel region 11B4 located on the outside tends to be the same as the smaller volatilization rate of the solvent in the display region 11A on the inside, reducing the risk of the 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 of the display area 11A along the second direction Y is also improved, which is beneficial 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. In this way, 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 area 11B4, better improving the uneven thickness problem of the display pixel 121 along the second direction Y, and thus facilitating the reduction of 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. In this way, 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 volatilization rate of the solvent in the fourth lateral redundant pixel area 11B4. The problem of uneven thickness of the display pixel 121 along the second direction Y is better improved, thereby facilitating the reduction of 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. In this way, 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 volatilization rate of the solvent in the corner redundant pixel area 11B5, better improving the uneven thickness problem of the display pixel 121 at the corner in 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. In this way, the total amount of ink droplets required to form the fourth lateral redundant pixel 125 can be larger than the total amount of ink droplets required to form the third lateral redundant pixel 124 and the total amount 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 area 11B4. The problem of uneven thickness of the display pixel 121 along the second direction Y is better improved, thereby facilitating the reduction of 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 and is respectively adjacent to two corner redundant pixel regions 11B5. In this way, the size of the fourth lateral redundant pixel 125 is relatively large, which is conducive to increasing the area of the fourth lateral redundant pixel 125, so that the total amount of ink droplets required to form the fourth lateral redundant pixel 125 is relatively large.
[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 area 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 pixel 125 is in a strip shape, which can make full use of the lateral space of the display area 11A and simplify 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, and the second edge L2 is aligned with the first edge L1. In this way, 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, the display pixel 121, the first lateral redundant pixel 122 to the fourth lateral redundant pixel 125, and the corner redundant pixel 126 may include an organic light-emitting material, but are not limited thereto. The organic light-emitting material includes at least one of a red light organic light-emitting material, a green light organic light-emitting material, and a blue light organic light-emitting material. The above-mentioned pixel can be obtained by spraying ink droplets and then removing the solvent in 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 region opening 131A. The display region opening 131A is located in the display region 11A, and the display region dam 131 is disposed around the display region opening 131A. The display pixel 121 is located in the display region opening 131A.
[0109] The pixel definition layer 13 includes a first lateral pixel opening 132A. The first lateral pixel opening 132A is located in the first lateral redundant pixel area 11B1. The first lateral redundant pixel 122 is located in the first lateral pixel opening 132A. In the case where 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 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. In this way, the first lateral pixel dam 132 and the display area dam 131 can be formed by the same process, simplifying the manufacturing process of the display panel 100. In addition, the structure around the first lateral pixel opening 132A is the same as that around the display area opening 131A, and 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 the second lateral redundant pixel region 11B2. The second lateral redundant pixel 123 is located in the second lateral pixel opening 133A. In the case where the second lateral redundant pixel 123 extends along the first direction X, the second lateral pixel opening 133A extends along the first direction X. In one second lateral redundant pixel region 11B2, in the case where a plurality of second lateral redundant pixels 123 are arranged at intervals along the second direction Y, the plurality of 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. In this way, the risk of ink droplets in the display area 11A flowing into the opening of the second lateral redundant pixel 123 is reduced, and the thickness uniformity of the display pixels 121 in the display area 11A along the first direction X is improved. 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). 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 shapes and sizes of the two are the same.
[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 arranged 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. In this way, the third lateral pixel dam and the display area dam 131 can be formed by the same process, simplifying the manufacturing process of the display panel 100. In addition, the structure around the third lateral pixel opening and the display area opening 131A is the same, and the third lateral redundant pixel 124 can better play a buffering role 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. In the case where 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, in the case where a plurality of fourth lateral redundant pixels 125 are arranged at intervals along the second direction Y, the plurality of 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 in the figure). The fourth lateral pixel dam is arranged 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. In this way, the risk of ink droplets in the display area 11A flowing into the fourth lateral pixel opening is reduced, and the thickness uniformity of the display pixels 121 in the display area 11A along the second direction Y is improved. 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 area 11B5. The corner redundant pixel 126 is located in the corner redundant pixel opening. When 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 in the figure). The corner redundant pixel dam is arranged 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 in the display area 11A flowing into the corner redundant pixel opening is reduced, and the thickness uniformity of the display pixel 121 at the corner 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.

The driving circuit layer 143 includes a pixel driving circuit connected to the anode 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 a display pixel 121, a first lateral redundant pixel 122, and a third lateral redundant pixel 124.

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