Description

Technical Field

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

[0002] High-resolution inkjet printing uses a pixel dam structure, where each subpixel of the same color is isolated from the others, preventing ink from flowing between them.

[0003] Due to the influence of ink droplet ejection volume and landing point deviation in the inkjet printing process, the ink volume distribution inside a single sub-pixel is uneven, resulting in poor consistency of film thickness after curing, which can easily cause defects such as uneven brightness and color deviation in the display panel.

[0004] It should be noted that the information in the background section above is only used to enhance the understanding of the background of the present invention, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0005] The purpose of this invention is to overcome the problems of uneven brightness and color deviation in display panels caused by uneven ink distribution within a single sub-pixel, and to provide a display panel and display device.

[0006] According to one aspect of the present invention, a display module is provided. The display panel includes a substrate and a plurality of sub-pixels of at least three different colors. The plurality of sub-pixels of at least three different colors are disposed on one side of the substrate. The plurality of sub-pixels are arranged in a plurality of sub-pixel rows along a first direction and in a plurality of sub-pixel columns along a second direction. The second direction intersects the first direction. In at least some of the sub-pixel rows and / or sub-pixel columns, the size of at least one color sub-pixel along the first direction is smaller than its size along the second direction, and the size of other different colors sub-pixels along the first direction is larger than their size along the second direction. The at least one color sub-pixel and other different colors sub-pixels are alternately arranged along the sub-pixel rows or sub-pixel columns.

[0007] In one embodiment of the present invention, a plurality of sub-pixels of at least three different colors include a first sub-pixel, a second sub-pixel, and a third sub-pixel of different colors. The size of the first sub-pixel and the second sub-pixel in a first direction is larger than the size in a second direction, and the size of the third sub-pixel in the first direction is smaller than the size in the second direction. The first sub-pixel and the second sub-pixel are arranged in a first sub-pixel group along the second direction, and two third sub-pixels are arranged in a second sub-pixel group along the first direction. In the same sub-pixel row, the first sub-pixel group and the second sub-pixel are alternately arranged along the first direction. In the same sub-pixel column, the first sub-pixel group and the second sub-pixel are alternately arranged along the second direction.

[0008] In one embodiment of the present invention, each sub-pixel row includes a first sub-pixel row, a second sub-pixel row, and a third sub-pixel row. The first sub-pixel row includes a first sub-pixel group and a second sub-pixel group. The first sub-pixel group includes two third sub-pixels.

The third sub-pixel row includes a plurality of second sub-pixels located on the same straight line along the first direction.

[0009] In one embodiment of the present invention, the plurality of sub-pixel columns include a plurality of odd-numbered sub-pixel columns and a plurality of even-numbered sub-pixel columns, which are arranged alternately along a first direction. The odd-numbered sub-pixel columns include a plurality of first pixel units arranged along a second direction. Each first pixel unit includes a first sub-pixel, a second sub-pixel, and a first sub-pixel group. The size of the first sub-pixel and the second sub-pixel in the odd-numbered sub-pixel columns is larger in the first direction than in the second direction. The first sub-pixel group includes two third sub-pixels, which have smaller sizes in the first direction than in the second direction. The first sub-pixel group, the first sub-pixel, and the second sub-pixel are arranged sequentially in the second direction. The even-numbered subpixel column includes a plurality of second pixel units arranged along the second direction. The second pixel unit includes a first subpixel, a third subpixel, and a second subpixel group. The size of the first subpixel and the third subpixel in the even-numbered subpixel column is larger in the first direction than in the second direction. The second subpixel group includes two first subpixels arranged along the first direction. The size of the two first subpixels in the second subpixel group is smaller in the first direction than in the second direction. The third subpixel, the second subpixel group, and the first subpixel are arranged sequentially in the second direction.

[0010] In one embodiment of the present invention, the ratio of the number of first sub-pixels, the number of second sub-pixels, and the number of third sub-pixels is 4:3:5.

[0011] In one embodiment of the present invention, the sub-pixel rows include multiple odd-numbered rows and even-numbered rows. Both odd-numbered and even-numbered rows include a first sub-pixel group, a second sub-pixel group, and a third sub-pixel group. The first sub-pixel group includes two first sub-pixels, the second sub-pixel group includes two second sub-pixels, and the third sub-pixel group includes two third sub-pixels. The dimensions of the first, second, and third sub-pixels in the odd-numbered rows are smaller in the third direction than in the fourth direction. The dimensions of the first, second, and third sub-pixels in the odd-numbered rows are larger in the third direction than in the fourth direction. The odd-numbered and even-numbered rows are alternately arranged along the fourth direction. The gaps between the first sub-pixel groups in the even-numbered rows and the first and second sub-pixel groups in the odd-numbered rows are opposite. The gaps between the second sub-pixel groups in the even-numbered rows and the second and third sub-pixel groups in the odd-numbered rows are opposite. The gaps between the third sub-pixel groups in the even-numbered rows and the first and third sub-pixel groups in the odd-numbered rows are opposite.

[0012] In one embodiment of the present invention, the first sub-pixel, the second sub-pixel, and the third sub-pixel are parallelogram structures. The first side of the first sub-pixel, the first side of the second sub-pixel, and the first side of the third sub-pixel extend along a third direction, and the second side of the first sub-pixel, the second side of the second sub-pixel, and the second side of the third sub-pixel extend along a fourth direction. The angle between the third direction and the fourth direction is less than 90 degrees.

[0013] In one embodiment of the present invention, a plurality of sub-pixels of at least three different colors include a first sub-pixel, a second sub-pixel, and a third sub-pixel of different colors. The size of the first sub-pixel in a first direction is smaller than its size in a second direction, and the sizes of the second and third sub-pixels in the first direction are larger than their sizes in the second direction. The at least three-color sub-pixels include a plurality of first sub-pixels and a plurality of first sub-pixel groups. The first sub-pixel groups include second and third sub-pixels that are alternately arranged along a second direction. The first sub-pixels and first sub-pixel groups in a sub-pixel row are alternately arranged along a first direction. A plurality of first sub-pixels in the same sub-pixel column are located on the same straight line along a second direction, and a plurality of first sub-pixel groups in the same sub-pixel column are located on the same straight line along a second direction.

[0014] In one embodiment of the present invention, at least three different colors of multiple sub-pixels include multiple sets of first sub-pixels, multiple sets of second sub-pixels and multiple sets of third sub-pixels of different colors. The size of the first sub-pixels and second sub-pixels in the first direction is smaller than the size in the second direction, and the size of the third sub-pixels in the first direction is larger than the size in the second direction. Two first sub-pixels of a set of first sub-pixels are arranged along the first direction, and two third sub-pixels of a set of third sub-pixels are arranged along the second direction. The same sub-pixel column includes a first sub-pixel column and a second sub-pixel column. The first sub-pixel column includes a set of first sub-pixels and a set of third sub-pixels alternately arranged along the second direction. The second sub-pixel column includes multiple second sub-pixels located on the same straight line along the second direction. A set of first sub-pixels and a set of third sub-pixels in the same sub-pixel row are alternately arranged along the first direction, and a second sub-pixel is provided between adjacent first sub-pixels and third sub-pixels.

[0015] According to another aspect of this application, a display device is provided, comprising a display panel provided in any one aspect of the present invention.

[0016] The display panel of the present invention includes a plurality of sub-pixels of at least three different colors. The plurality of sub-pixels are arranged in a plurality of sub-pixel rows along a first direction and in a plurality of sub-pixel columns along a second direction. When sub-pixels of at least one color are alternately arranged with sub-pixels of other different colors along sub-pixel rows, the distance between two adjacent sub-pixels of the same color is equal to the size of the sub-pixels of other different colors in the first direction, and the size of the sub-pixels of other different colors along the first direction is greater than the size along the second direction. When sub-pixels of at least one color are alternately arranged with sub-pixels of other different colors along sub-pixel columns, the distance between the sub-pixels of other different colors is equal to the distance between sub-pixels of one color in the second direction, and the size of the sub-pixels of at least one color along the second direction is greater than the size along the first direction. Increasing the distance between two adjacent subpixels of the same color in the same row or column along the first or second direction significantly reduces the density of subpixels of the same color. When printing one type of subpixel along the second direction and other types of subpixels of different colors along the first direction, the inkjet printing frequency can be reduced. At a lower inkjet frequency, the printing accuracy is improved, resulting in a more uniform ink distribution across individual subpixels and ensuring consistent brightness and color uniformity of the display panel. Furthermore, without increasing the printing accuracy, the inkjet printhead has a larger margin, allowing for a slight increase in the density of subpixels of the same color, thereby improving the pixel density of the display panel.

Detailed Implementation

[0052] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that the invention will be thorough and complete, and the concept of the exemplary embodiments will be fully conveyed to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted. Furthermore, the drawings are merely illustrative of the invention and are not necessarily drawn to scale.

[0053] Although relative terms such as "upper" and "lower" are used in this specification to describe the relative relationship of one component of an icon to another, these terms are used only for convenience, such as according to the orientation of the examples in the accompanying drawings. It is understood that if the device of the icon is flipped so that it is upside down, the component described as "upper" will become the component described as "lower." When a structure is "upper" of another structure, it may mean that the structure is integrally formed on the other structure, or that the structure is "directly" mounted on the other structure, or that the structure is "indirectly" mounted on the other structure through another structure.

[0054] The terms “a,” “one,” “the,” “the,” and “at least one” are used to indicate the existence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended inclusion and to mean that there may be other elements / components / etc. in addition to the listed elements / components / etc.; the terms “first,” “second,” and “third,” etc., are used only as markers and are not a limitation on the number of objects.

[0055] like Figure 1 As shown, the display panel includes multiple sub-pixels 1 of three different colors. The multiple sub-pixels 1 of the three different colors include multiple first sub-pixels 101, multiple second sub-pixels 102, and multiple third sub-pixels 103. The multiple first sub-pixels 101 are arranged along a second direction to form a column of first sub-pixels 101, the multiple second sub-pixels 102 are arranged along a second direction to form a column of second sub-pixels 102, and the multiple third sub-pixels 103 are arranged along a second direction to form a column of third sub-pixels 103. The columns of first sub-pixels 101, second sub-pixels 102, and third sub-pixels 103 are arranged alternately along a first direction. Different sub-pixels are separated by pixel definition parts 22. The pixel definition parts 22 include a first pixel definition part 221 and a second pixel definition part 222. The height of the first pixel definition part 221 is greater than the height of the second pixel definition part 222. The first pixel definition part 221 is disposed between adjacent sub-pixels 1 of different colors, and the second pixel definition part 222 is disposed between adjacent sub-pixels 1 of the same color.

[0056] When forming multiple sub-pixels 1 of different colors, high-resolution inkjet printing employs a pixel dam structure, where each sub-pixel 1 of the same color is independently isolated, preventing ink from flowing between them. The minimum distance that can be set between nozzles 61 is limited, because... Figure 1 The small size between two adjacent sub-pixels 1 means that during inkjet printing, ink droplets from one sub-pixel 1 can easily be sprayed onto the position of another sub-pixel 1, resulting in ink cross-contamination. Furthermore, because unidirectional inkjet printing requires nozzles 61 to operate at a high frequency, the inkjet precision of nozzles 61 is poor under high-frequency inkjet conditions. Affected by the volume and landing point deviation of ink droplets during the inkjet printing process, the ink distribution within a single sub-pixel 1 is uneven, resulting in poor consistency in film thickness after curing. This can easily cause defects such as uneven brightness and color shift in the display panel.

[0057] Based on this, embodiments of the present invention provide a display panel. For example... Figures 2 to 32 As shown, the display panel includes a substrate 5 and a plurality of sub-pixels 1 of at least three different colors. The plurality of sub-pixels 1 of at least three different colors are disposed on one side of the substrate 5. The plurality of sub-pixels 1 are arranged in a plurality of sub-pixel 1 rows along a first direction and in a plurality of sub-pixel 1 columns along a second direction. The second direction intersects with the first direction. In at least some of the sub-pixel 1 rows and / or sub-pixel 1 columns, the size of at least one color of sub-pixel 1 along the first direction is smaller than the size along the second direction, and the size of other different colors of sub-pixels 1 along the first direction is larger than the size along the second direction. The at least one color of sub-pixels 1 and other different colors of sub-pixels 1 are alternately arranged along the sub-pixel 1 rows or sub-pixel 1 columns.

[0058] Multiple sub-pixels 1 are arranged in multiple rows along a first direction and in multiple columns along a second direction. When sub-pixels 1 of at least one color are alternately arranged with sub-pixels 1 of other different colors along the rows of sub-pixels 1, the distance between two adjacent sub-pixels 1 of one color is equal to the size of the sub-pixels 1 of other different colors in the first direction, and the size of the sub-pixels 1 of other different colors along the first direction is greater than the size along the second direction. When sub-pixels 1 of at least one color are alternately arranged with sub-pixels 1 of other different colors along the columns of sub-pixels 1, the distance of the sub-pixels 1 of other different colors is equal to the distance of the sub-pixels 1 of one color in the second direction, and the size of the sub-pixels 1 of at least one color along the second direction is greater than the size along the first direction. Increasing the distance between two adjacent sub-pixels of the same color in the same row or column along the first or second direction significantly reduces the density of sub-pixels of the same color. When printing one type of sub-pixel along the second direction and other types of sub-pixels of different colors along the first direction, the inkjet printing frequency can be reduced. With a lower inkjet frequency, the printing accuracy is improved, resulting in a more uniform ink distribution across individual sub-pixels, ensuring consistent brightness and color uniformity of the display panel. Furthermore, without increasing the printing accuracy, the inkjet printhead has a larger margin, allowing for a slight increase in the density of sub-pixels of the same color, thereby improving the pixel density of the display panel.

[0059] The display panel involved in the embodiments of the present invention will be described in detail below with reference to specific examples.

[0060] like Figure 2 As shown, the display panel includes a substrate 5 and a plurality of sub-pixels 1 of at least three different colors. The plurality of sub-pixels 1 of at least three different colors includes a plurality of first sub-pixels 101, a plurality of second sub-pixels 102, and a plurality of third sub-pixels 103. The first sub-pixels 101 are red, the second sub-pixels 102 are green, and the third sub-pixels 103 are blue. The dimensions of the first sub-pixels 101 and the second sub-pixels 102 in a first direction are both larger than their dimensions in a second direction. The dimensions of the third sub-pixels 103 in the first direction are smaller than their dimensions in the second direction.

[0061] Multiple first sub-pixels 101, multiple second sub-pixels 102, and multiple third sub-pixels 103 are arranged in multiple sub-pixel rows along a first direction and in multiple sub-pixel columns along a second direction. The first sub-pixels 101 and second sub-pixels 102 are arranged in a first sub-pixel group 11 along the second direction, and the two third sub-pixels 103 are arranged in a second sub-pixel group 12 along the first direction. In odd-numbered sub-pixel rows, the first sub-pixel group 11 and the second sub-pixel group 12 alternate sequentially; in even-numbered sub-pixel rows, the second sub-pixel group 12 and the first sub-pixel group 11 alternate sequentially. In odd-numbered sub-pixel columns, the first sub-pixel group 11 and the second sub-pixel group 12 alternate sequentially; in even-numbered sub-pixel columns, the second sub-pixel group 12 and the first sub-pixel group 11 alternate sequentially.

[0062] like Figure 3 As shown, in column 1 of subpixels, the distance d1 between two adjacent first subpixels 101 in the second direction is greater than the sum of the dimensions of the second subpixel 102 and the third subpixel 103 in the second direction; similarly, the distance d2 between two adjacent second subpixels 102 in the first direction is greater than the sum of the dimensions of the first subpixel 101 and the third subpixel 103 in the second direction. In row 1 of subpixels, the distance d3 between two adjacent second subpixel groups 12 in the first direction is greater than the dimensions of either the first subpixel 101 or the second subpixel 102 in the first direction.

[0063] like Figure 4 As shown, the nozzle 61 of the inkjet device 6 is moved along a first direction to print the first sub-pixel 101 and the second sub-pixel 102. Then, the nozzle 61 is rotated by the first rotating device 62 and moved along a second direction. The stage 64 is rotated by the second rotating device 363, while the direction of movement of the nozzle 61 remains unchanged, and the third sub-pixel 103 continues to be printed. It can be understood that the distance between two adjacent sub-pixels of the same color in the same row or column of sub-pixels increases in both the first and second directions.

[0064] While maintaining consistent inkjet printing precision, the inkjet printhead has a larger margin, allowing for a slight increase in the density of sub-pixels of the same color, thereby improving the pixel density of the display panel. Increasing the distance between adjacent sub-pixels of the same color allows for a reduction in the inkjet printing frequency. At a lower frequency, the printing precision improves, ensuring that ink droplets fall more accurately into their corresponding sub-pixels, thus preventing ink cross-contamination.

[0065] like Figure 5 As shown, the relationship between the area uniformity of a single sub-pixel 1, the area uniformity of sub-pixel 1 along the major axis, and the area uniformity of sub-pixel 1 along the minor axis is as follows: U(S1) = U(L1) × U(LS), where U(L1) represents the uniformity of sub-pixel 1 along its major axis. This uniformity value U(L1) is the percentage of the length of the uniformly emitting portion of sub-pixel 1 along its major axis to the total length L1 of sub-pixel 1 along its major axis. U(LS) represents the uniformity of sub-pixel 1 along its minor axis. This uniformity value U(LS) is the percentage of the length of the uniformly emitting portion of sub-pixel 1 along its minor axis to the total length LS of sub-pixel 1 along its minor axis. U(S1) is the area uniformity value of a single sub-pixel 1, which is a percentage value. This area uniformity also reflects the uniformity of the film thickness within a certain area (especially within the area of ​​sub-pixel 1). The length of sub-pixel 1 along its major axis is L1, the length along its minor axis is LS, and S1 is the area of ​​sub-pixel 1.

[0066] For a single sub-pixel 1, after ink is printed, the ink in each column of sub-pixels of the same color is separated from each other; however, for a pattern section 301 (Line Bank) connecting multiple sub-pixels of the same color, after ink is printed, the ink in each column of sub-pixels of the same color flows between each other, and the ink within each sub-pixel 1 is averaged in the pattern section 301. Therefore, the pattern section 301 formed by connecting multiple sub-pixels 1 can effectively improve the uniformity of the printed film within a pixel. Multiple first sub-pixels 101 are connected to form a first pattern section 3011, multiple second sub-pixels 102 are connected to form a second pattern section 3012, and multiple third sub-pixels 103 are connected to form a third pattern section 3013.

[0067] like Figure 6 As shown, the relationship between the area uniformity, the uniformity along the major axis, and the uniformity along the minor axis of two adjacent sub-pixels 1 connected along the second direction is as follows: U(S2) = U(L2) × U(LS), where U(L2) represents the uniformity value of two adjacent sub-pixels of the same color connected along the second direction in the long axis direction. This uniformity value U(L2) is the percentage of the length of the uniformly emitting portion of the two adjacent sub-pixels of the same color in the long axis direction relative to the length L2 of the two sub-pixels of the same color in the long axis direction. U(LS) represents the uniformity value of two adjacent sub-pixels of the same color connected along the second direction in the short axis direction. This uniformity value U(LS) is the percentage of the length of the uniformly emitting portion of the two adjacent sub-pixels of the same color in the short axis direction relative to the length LS of the two connected sub-pixels of the same color in the short axis direction. U(S2) is the area uniformity value of two adjacent sub-pixels of the same color connected along the second direction. The length of the two adjacent sub-pixels of the same color connected along the second direction in the long axis direction is L2, the length of the two adjacent sub-pixels of the same color connected along the second direction in the short axis direction is LS, and S2 is the area of ​​the two adjacent sub-pixels of the same color connected along the second direction.

[0068] like Figure 7 As shown, the major axes of two adjacent sub-pixels of the same color along the first direction can also be connected. For example... Figure 8 As shown, the major axes of adjacent sub-pixels 1 of the same color along the first direction can be connected, while the minor axes of adjacent sub-pixels 1 of the same color along the second direction can also be connected. This results in a longer connection length for sub-pixels 1 of the same color, and better uniformity of the area of ​​the connected sub-pixels 1 of the same color.

[0069] By printing in different directions, sub-pixel 1 combinations in different directions can be achieved, and sub-pixels 1 of the same color can be connected to achieve efficient and stable printing. Because inkjet printers can print at rotating angles and can achieve printing at different positions by editing the printed pattern, all sub-pixels 1 must be parallel. Since the print head is a three-column parallel array, the corresponding printed pattern also needs to be a parallel array of sub-pixels 1, such as... Figure 9 As shown.

[0070] like Figures 9 to 11As shown, each sub-pixel row 1 includes a first sub-pixel row 101, a second sub-pixel row 102, and a third sub-pixel row 103. The first sub-pixel row 101 includes a first sub-pixel group 11 and a second sub-pixel group 12. The first sub-pixel group 11 includes two third sub-pixels 101, and the second sub-pixel group 12 includes one first sub-pixel 101 and one third sub-pixel 103. The size of the two third sub-pixels 103 in the first sub-pixel group 11 is smaller in the first direction than in the second direction. The size of the first sub-pixel 101 and the third sub-pixel 103 in the second sub-pixel group 12 is larger in the first direction than in the second direction. The first sub-pixel 101 and the third sub-pixel 103 in the second sub-pixel group 12 are symmetrically arranged about a first symmetry line. The first symmetry line can pass through the center of the two third sub-pixels 103 in the first sub-pixel group 11 and extends along the first direction. The first sub-pixel group 11 and the second sub-pixel group 12 are arranged alternately along the first direction. The second sub-pixel row 102 includes a plurality of first sub-pixels 101 located on the same straight line along the first direction. The third sub-pixel row 103 includes a plurality of second sub-pixels 102 located on the same straight line along the first direction.

[0071] The plurality of sub-pixel columns include a plurality of odd-numbered sub-pixel columns and a plurality of even-numbered sub-pixel columns, which are arranged alternately along a first direction. The odd-numbered sub-pixel columns include a plurality of first pixel units 1001 arranged along a second direction. Each first pixel unit 1001 includes a first sub-pixel 101, a second sub-pixel 102, and a first sub-pixel group 11. The dimensions of the first sub-pixel 101 and the second sub-pixel 102 in the odd-numbered sub-pixel columns are larger in the first direction than in the second direction. The first sub-pixel group 11 includes two third sub-pixels 103 arranged along the first direction, with the dimensions of the two third sub-pixels 103 in the first sub-pixel group 11 being smaller in the first direction than in the second direction. The first sub-pixel group 11, the first sub-pixel 101, and the second sub-pixel 102 are arranged sequentially in the second direction. The two third sub-pixels 103 in the first sub-pixel group 11 are symmetrically arranged about a second symmetry line, which passes through the center of the first sub-pixel 101 and the center of the second sub-pixel 102 of the first pixel unit 1001, and extends along the second direction.

[0072] The even-numbered subpixel column 1 includes a plurality of second pixel units 1002 arranged along a second direction. Each second pixel unit 1002 includes a first subpixel 101, a third subpixel 103, and a second subpixel group 12. The dimensions of the first subpixel 101 and the third subpixel 103 in the even-numbered subpixel column 1 are larger in the first direction than in the second direction. The second subpixel group 12 includes two first subpixels 101 arranged sequentially along the second direction. The dimensions of the two first subpixels 101 in the second subpixel group 12 are larger in the first direction than in the second direction. The third subpixel 103, the second subpixel group 12, and the first subpixel 101 are arranged sequentially in the second direction. Both the first pixel unit 1001 and the second pixel unit 1002 can be referred to as pixel unit 100.

[0073] exist Figures 9 to 11 In the process, the second sub-pixel 102 can be inkjet printed along the axis S11 extending in the first direction, the third sub-pixel 103 arranged along the first direction can be inkjet printed along the axis S12 extending in the first direction, the first sub-pixel 101 can be inkjet printed along the axes S13 and S14 extending in the first direction, and two columns of the third sub-pixel 103 arranged in the second direction can be inkjet printed along the axes S21 and S22 extending in the second direction.

[0074] like Figure 12 As shown, a pixel definition section 22 is provided between different first sub-pixels 101, between different second sub-pixels 102, and between different third sub-pixels 103. The pixel definition section 22 is a second pixel definition section 222 with a lower height. The ink for printing the same seed pixel 1 can pass through the second pixel definition section 222 and flow between different sub-pixels 1 of the same seed pixel 1. The ink in each sub-pixel 1 is averaged in the pattern section 301. Therefore, the pattern section 301 formed by connecting multiple sub-pixels 1 can effectively improve the uniformity of the printed film within the pixel.

[0075] like Figure 13 As shown, with Figure 9 The difference lies in that the second sub-pixel group 12 of the even-numbered sub-pixel column includes two first sub-pixels 101 arranged sequentially along the first direction. The size of the two first sub-pixels 101 in the second sub-pixel group 12 in the first direction is smaller than its size in the second direction. The two first sub-pixels 101 of the second sub-pixel group 12 are symmetrically arranged about a third symmetry line, which extends along the second direction and can pass through the center of the first sub-pixel 101 and the center of the third sub-pixel 103 of the second pixel unit 1002.

[0076] exist Figure 13In this process, a second sub-pixel 102 can be inkjet printed along axis S11 extending in the first direction; a third sub-pixel 103 arranged along the first direction can be inkjet printed along axis S12 extending in the first direction; a first sub-pixel 101 arranged in the first direction can be inkjet printed along axis S14 extending in the first direction; two columns of third sub-pixels 103 arranged in the second direction can be inkjet printed along axes S21 and S22 extending in the second direction; and two columns of first sub-pixels 101 arranged in the second direction can be inkjet printed along axes S23 and S24 extending in the second direction.

[0077] like Figure 14 As shown, pixel definition sections 22 are provided between different first sub-pixels 101, between different second sub-pixels 102, and between different third sub-pixels 103. The pixel definition sections 22 are second pixel definition sections 222 with a lower height. Ink that prints the same seed pixel 1 can pass through the second pixel definition section 222 and flow between different sub-pixels 1 of the same seed pixel 1. The ink in each sub-pixel 1 is averaged in the pattern section 301. Therefore, the pattern section 301 formed by connecting multiple sub-pixels 1 can effectively improve the uniformity of the printed film within the pixel, thereby further improving the consistency of the film thickness after curing.

[0078] It should be noted that, in Figure 8 and Figure 13 The ratio of the number of the first sub-pixel 101, the number of the second sub-pixel 102, and the number of the third sub-pixel 103 is 4:3:5.

[0079] like Figure 15 As shown, sub-pixel row 1 includes multiple odd-numbered sub-pixel rows 1 and even-numbered sub-pixel rows 1. Both odd-numbered and even-numbered sub-pixel rows 1 include a first sub-pixel group 11, a second sub-pixel group 12, and a third sub-pixel group 103. The first sub-pixel group 11 includes two first sub-pixels 101, the second sub-pixel group 12 includes two second sub-pixels 102, and the third sub-pixel group 103 includes two third sub-pixels 103. The dimensions of the first sub-pixels 101, second sub-pixels 102, and third sub-pixels 103 in the odd-numbered sub-pixel rows 1 are smaller in the first direction than in the second direction. The dimensions of the first sub-pixels 101, second sub-pixels 102, and third sub-pixels 103 in the even-numbered sub-pixel rows 1 are smaller in the first direction than in the second direction. 01. The size of the second sub-pixel 102 and the third sub-pixel 103 in the first direction is larger than the size in the second direction. Odd-numbered sub-pixel rows 1 and even-numbered sub-pixel rows 1 are alternately arranged along the second direction. The gap between the first sub-pixel group 11 of the even-numbered sub-pixel rows 1 and the first sub-pixel group 11 and the second sub-pixel group 12 of the odd-numbered rows 1 are opposite. The gap between the second sub-pixel group 12 of the even-numbered sub-pixel rows 1 and the second sub-pixel group 12 and the third sub-pixel group 103 of the odd-numbered rows 1 are opposite. The gap between the third sub-pixel group 103 of the even-numbered sub-pixel rows 1 and the first sub-pixel group 11 and the third sub-pixel group 103 of the odd-numbered rows 1 are opposite.

[0080] With the length of the major axis and the length of the minor axis of sub-pixel 1 remaining unchanged, the shape of sub-pixel 1 can be set as a parallelogram. The shape of the pixel definition portion 22 between the sub-pixels 1 of the parallelogram is also a parallelogram. When the area of ​​the pixel definition portion 22 of the parallelogram is the same as the area of ​​the pixel definition portion 22 of the rectangle, the dimension of the pixel definition portion 22 of the parallelogram in the third direction is larger than the dimension of the pixel definition portion 22 of the rectangle in the third direction. By using a pixel definition portion 22 of the parallelogram with a larger width, the ink will have a larger area to spread after the width is increased, which enhances the flowability of the ink and helps the ink to flow evenly into each pixel opening 21 within the pattern portion 301.

[0081] To facilitate the calculation of the area uniformity of two interconnected sub-pixels 1, we can... Figure 16 To simplify, Figure 16 The simplified model is as follows Figure 17 As shown, the relationship between the area uniformity, the uniformity along the major axis, and the uniformity along the minor axis of two staggered and interconnected sub-pixels 1 is as follows: like Figure 17 As shown, U(S3) = U(L1) U(L'S)≈U(L1) U(L1), where U(L1) represents the uniformity value of two interleaved and interconnected sub-pixels 1 along the major axis, and this uniformity value U(L1) is the percentage of the length of the uniformly emitting sub-pixel 1 portion along the major axis of the two interleaved and interconnected sub-pixels 1 along the major axis to the total length L1 of the two interleaved and interconnected sub-pixels 1 along the major axis. U(L'S) represents the uniformity value of two interleaved and interconnected sub-pixels 1 along the minor axis, and this uniformity value U(L'S) is the percentage of the length of the uniformly emitting sub-pixel 1 portion along the minor axis of the two interleaved and interconnected sub-pixels 1 along the minor axis to the total length L'S of the two interleaved and interconnected sub-pixels 1 along the minor axis. U(S3) is the area uniformity value of two interleaved and interconnected sub-pixels 1. Here, the minor axis portion that is not actually connected in the middle is not considered when calculating the area. The length L'S of two side-by-side sub-pixels 1 along the minor axis is given by S, and the length L1 of sub-pixels 1 along the major axis is given by S3. S3 is the area of ​​two interleaved and interconnected sub-pixels 1.

[0082] like Figure 18As shown, in order to increase the ink flow between two interleaved and interconnected sub-pixels 1, the length of the common major axis of the two sub-pixels 1 can be increased, and the length of the pixel definition portion 22 between the two sub-pixels 1 can be increased, thereby increasing the ink flow between the two interconnected sub-pixels 1. At the same time, the area uniformity of the two interleaved and interconnected sub-pixels 1 can also be increased.

[0083] like Figure 19 and Figure 20 As shown, a patterned area 301 (Line Bank) connecting multiple pixel openings 21 is formed on the pixel definition layer 2 using a half-etching process, which can be completed in one exposure and development step. The light transmittance of the first light-transmitting area 71 of the mask 7 is 0%, and adhesive material will remain below the non-light-transmitting area. The transmittance of the second light-transmitting area 72 of the mask 7 is greater than 0% and less than 100%, and the transmittance of the second light-transmitting area 72 of the mask 7 is determined according to the height of the second pixel definition section 222. In order to prevent ink cross-contamination between two adjacent sub-pixels 1, the pixel definition section 22 should also have a surface hydrophobic property.

[0084] The process steps for the patterned portion 301 connecting multiple sub-pixels 1 are as follows: a full-surface pixel definition layer 2 is uniformly coated on a substrate 5, the solvent in the full-surface pixel definition layer 2 is dried at low temperature, the full-surface pixel definition layer 2 is exposed through a mask 7, the unexposed areas of the full-surface pixel definition layer 2 are etched away to form the patterned portion 301, the pixel definition portion 22 is formed between adjacent patterned portions 301, the pixel definition portion 22 is heated and strengthened, and the strengthened pixel definition portion 22 is irradiated with ultraviolet light to give the pixel definition surface a hydrophobic effect.

[0085] like Figure 20 As shown, multiple sub-pixels 1 of different colors form a pixel layer 3. The pixel layer 3 includes a functional layer 31 and a light-emitting material layer 32. The functional layer 31 includes a first functional part 311, a second functional part 312, and a third functional part 313. The light-emitting material layer 32 includes a first light-emitting part 321, a second light-emitting part 322, and a third light-emitting part 323. First, the first functional part 311, the second functional part 312, and the third functional part 313 are printed in the first connecting part 23, the second connecting part 24, and the third connecting part 25, respectively. Then, the first light-emitting part 321 is formed on the side of the first functional part 311 away from the substrate 5, the second light-emitting part 322 is formed on the side of the second functional part 312 away from the substrate 5, and the third light-emitting part 323 is formed on the side of the third functional part 313 away from the substrate 5. The first light-emitting part 321 and the first functional part 311 form the first pattern part 3011, the second light-emitting part 322 and the second functional part 312 form the second pattern part 3012, and the third light-emitting part 323 and the third functional part 313 form the third pattern part 3013.

[0086] like Figure 21 As shown, the size of the first sub-pixel 101 in the first direction can also be set to be smaller than that in the second direction, and the sizes of the second sub-pixel 102 and the third sub-pixel 103 in the first direction can be larger than those in the second direction. At least three color sub-pixels 1 include multiple pixel units 100. The pixel unit 100 includes a first sub-pixel 101 and a first sub-pixel group 11. The first sub-pixel group 11 includes a second sub-pixel 102 and a third sub-pixel 103 that are alternately arranged along the second direction. The first sub-pixel 101 and the first sub-pixel group 11 in the sub-pixel 1 row are alternately arranged along the first direction. Multiple first sub-pixels 101 in the same sub-pixel 1 column are located on the same straight line along the second direction. Multiple first sub-pixel groups 11 in the same sub-pixel 1 column are located on the same straight line along the second direction.

[0087] like Figure 22 As shown, the dimensions of the first sub-pixel 101 and the second sub-pixel 102 in the first direction can be set to be smaller than their dimensions in the second direction, and the dimension of the third sub-pixel 103 in the first direction can be set to be larger than its dimensions in the second direction. The same sub-pixel column includes a first sub-pixel column and a second sub-pixel column. The first sub-pixel column includes a group of first sub-pixels 101 and a group of third sub-pixels 103 alternately arranged along the second direction. The two first sub-pixels 101 of the group of first sub-pixels 101 are arranged along the first direction, and the two third sub-pixels 103 of the group of third sub-pixels 103 are arranged along the second direction. The second sub-pixel column includes multiple second sub-pixels 102 located on the same straight line along the second direction. The two first sub-pixels 101 and two third sub-pixels in the same sub-pixel row are alternately arranged along the first direction. A second sub-pixel 102 is provided between adjacent first sub-pixels 101 and third sub-pixels 103, that is, the first sub-pixels 101 and third sub-pixels 103 are located on both sides of the second sub-pixel 102 along the first direction. One second sub-pixel 102 and two adjacent third sub-pixels 103 can form a pixel unit. Two sets of first sub-pixels 101, two sets of third sub-pixels 103, and two second sub-pixels 102 located in region A form a arrangement cycle.

[0088] like Figure 23 As shown, the display panel also includes multiple data lines 4 and multiple columns of sub-pixels 1. The multiple data lines 4 are divided into three types: the first type connects to a column of first sub-pixels 101, the second type connects to a column of second sub-pixels 102, and the third type connects to a column of third sub-pixels 103. The first sub-pixels 101, second sub-pixels 102, and third sub-pixels 103 are arranged alternately in the first direction. Figure 24 As shown, in Figure 23 Based on this, the first sub-pixel 101, the second sub-pixel 102, and the third sub-pixel 103 can also be arranged in an alternating manner in the second direction, thereby increasing the uniformity of light emission of the display panel.

[0089] The improvement in the arrangement of sub-pixel 1 above mainly shows that, according to Figure 23 and Figure 24 The result of deforming the arrangement of sub-pixel 1 in the image. Alternatively, the above deformation method can be used to modify... Figures 25 to 32 The arrangement of sub-pixels 1 is changed, while retaining the advantages of the original arrangement, thereby improving the accuracy of inkjet printing and making the ink distribution of each sub-pixel 1 uniform, ensuring the brightness and color uniformity of the display panel.

[0090] For example: Figure 25 The pixel arrangement in the image is modified according to the above deformation method. Figure 25 Sub-pixels 1 in different rows can still be staggered by a certain distance, ensuring high space utilization while guaranteeing uniform ink distribution for each individual sub-pixel 1. For example: Figure 26 and Figure 27 After modifying the pixel arrangement according to the above deformation method, even when enlarging the area of ​​the third sub-pixel 103 with the worst lifespan, it is possible to ensure uniform ink distribution in a single sub-pixel 1. For example: Figure 28 and Figure 29 After the pixel arrangement is modified according to the above deformation method, while increasing the proportion of the second sub-pixel 102 and improving the visual equivalent resolution, the ink distribution of a single sub-pixel 1 can be guaranteed to be uniform.

[0091] For example: to Figure 30 The arrangement of hexagonal sub-pixels 1 in the image is modified according to the above deformation method. While maintaining better isotropy in all directions, this ensures a uniform ink distribution for each sub-pixel 1. Figure 31 Using the central sub-pixel 1 as a baseline, and with the four corner sub-pixels 1 arranged symmetrically and modified according to the above deformation method, the color of the display panel can be more uniform when visual sampling is uniform in all directions and the diagonal image performance is more balanced. Figure 32 By adding a white fourth sub-pixel 1 to the arrangement of the pixels, the arrangement can be modified in accordance with the above deformation method. This can improve the brightness of the display panel and make the color of the display panel more uniform.

[0092] It should be noted that the first direction is the x-direction of the graph, the second direction is the y-direction of the graph, the third direction is the m-direction of the graph, and the fourth direction is the n-direction of the graph.

[0093] This invention also provides a display device, which may include the display module described in any of the above embodiments of this invention.
