[0023] The present application will be described in further detail below in conjunction with the accompanying drawings and examples. It is particularly noted that the following examples are intended only to illustrate the present application and are not intended to limit the scope of the present application. Similarly, the following examples are only some examples of the present application and are not intended to be exhaustive. All other examples obtained by persons of ordinary skill in the art without creative effort are intended to fall within the scope of protection of the present application.

[0024] See also Figure 1 , Figure 1 Schematic diagram of the top view of the display panel provided in the embodiment of the present application. Figure 1 As shown, the display panel may include a plurality of pixel units 10 arranged in rows and columns, and each pixel unit 10 may include at least one first primary color photon pixel 11 and at least one second primary color photon pixel 12 arranged around the at least one first primary color photon pixel 11 .

[0025] In this embodiment, two adjacent pixel units 10 (for example, Figure 1 A pixel unit 10 (for example, a first pixel unit P1 and a second pixel unit P2) Figure 1 The first pixel unit P1 in the embodiment includes at least one second primary color photon pixel 12 and another pixel unit 10 (for example, Figure 1 The at least one second primary color photon pixel 12 included in the second pixel unit P2 in the image may be adjacent to each other. Figure 1 As shown, the two second primary color photon sub-pixels 12 of the first pixel unit P1 are arranged adjacent to the two second primary color photon sub-pixels 12 of the second pixel unit P2.

[0026] Specifically, if Figure 1 As shown, each pixel unit 10 may further include at least one third primary color photon pixel 13, and in each pixel unit 10, the at least one third primary color photon pixel 13 and the at least one second primary color photon pixel 12 may be disposed together around the at least one first primary color photon pixel 11. Furthermore, two adjacent pixel units 10 (for example, Figure 1 A pixel unit 10 (for example, a first pixel unit P1 and a second pixel unit P2) Figure 1 The first pixel unit P1 in the embodiment includes at least one third primary color photon pixel 13 and another pixel unit 10 (for example, Figure 1 The at least one third primary color photon pixel 13 included in the second pixel unit P2 in the image may be adjacent to each other. Figure 1 As shown, the two third primary color photon sub-pixels 13 of the first pixel unit P1 are arranged adjacent to the two third primary color photon sub-pixels 13 of the second pixel unit P2.

[0027] In some specific embodiments, Figure 1 As shown, each pixel unit 10 may include a plurality of first primary color photon pixels 11, and the plurality of first primary color photon pixels 11 may be arranged in rows and columns and disposed adjacent to each other. Figure 1 As shown, each pixel unit 10 may include six first primary color photon pixels 11 , and the six first primary color photon pixels 11 may be arranged in two rows and three columns and disposed adjacent to each other.

[0028] In this embodiment, each primary color photon pixel 11 / 12 / 13 may include an anode, a cathode, and a light-emitting functional layer located between the anode and the cathode in the longitudinal direction Z, and the light-emitting functional layer of each primary color photon pixel 11 / 12 / 13 may be formed by an inkjet printing process.

[0029] Specifically, when using an inkjet printing process to prepare the light-emitting functional layer of the first primary color photon pixel 11 in the display panel, the region where the adjacent first primary color photon pixel 11 is located in the display panel can be treated as a whole printing region for inkjet printing of the light-emitting material to form the light-emitting functional layer of the adjacent first primary color photon pixel 11 in the display panel. That is, the light-emitting functional layer of the adjacent first primary color photon pixel 11 in the display panel can be formed by a single inkjet printing process, and thus the light-emitting functional layer of the adjacent first primary color photon pixel 11 in the display panel can be connected as a whole.

[0030] Specifically, when using an inkjet printing process to prepare the light-emitting functional layer of the second primary color photon pixel 12 in the display panel, the region where the adjacent plurality of second primary color photon pixels 12 are located in the display panel can be treated as a whole printing region for inkjet printing of the light-emitting material to form the light-emitting functional layer of the adjacent plurality of second primary color photon pixels 12 in the display panel. That is, the light-emitting functional layer of the adjacent plurality of second primary color photon pixels 12 in the display panel can be formed by a single inkjet printing process, and thus the light-emitting functional layers of the adjacent plurality of second primary color photon pixels 12 in the display panel can be connected as a whole.

[0031] Specifically, when using an inkjet printing process to prepare the light-emitting functional layer of the third primary color photon sub-pixels 13 in the display panel, the region where the adjacent plurality of third primary color photon sub-pixels 13 are located in the display panel can be treated as a whole printing region for inkjet printing of the light-emitting material to form the light-emitting functional layer of the adjacent plurality of third primary color photon sub-pixels 13 in the display panel. That is, the light-emitting functional layer of the adjacent plurality of third primary color photon sub-pixels 13 in the display panel can be formed by a single inkjet printing process, and thus the light-emitting functional layers of the adjacent plurality of third primary color photon sub-pixels 13 in the display panel can be connected as a whole.

[0032] It should also be noted that, in this embodiment, by arranging at least one second primary color photon pixel 12 of one pixel unit 10 in two adjacent pixel units 10 adjacent to at least one second primary color photon pixel 12 of the other pixel unit 10, and arranging at least one third primary color photon pixel 13 of one pixel unit 10 in two adjacent pixel units 10 adjacent to at least one third primary color photon pixel 13 of the other pixel unit 10, it is ensured that when preparing the second primary color photon pixel 12 and the third primary color photon pixel 13 in the above-mentioned display panel, a plurality of second primary color photon pixels 12 belonging to different pixel units 10 but adjacent to each other can be formed by the same inkjet printing operation, and a plurality of third primary color photon pixels 13 belonging to different pixel units 10 but adjacent to each other can be formed by the same inkjet printing operation. Therefore, the inkjet area of ​​a single inkjet printing operation is increased, and the difficulty of printing the luminescent material is reduced, so that a high-resolution display panel can still be prepared even when the inkjet printing accuracy of the inkjet printing equipment is not high enough.

[0033] In some specific embodiments, Figure 1 As shown, in each pixel unit 10, the number of second primary color photon pixels 12 can be multiple, and the multiple second primary color photon pixels 12 can be divided into a plurality of second primary color photon pixel groups 12A arranged at intervals, and a second primary color photon pixel group 12A can include one second primary color photon pixel 12 or at least two adjacent second primary color photon pixels 12.

[0034] In one example, if Figure 1 As shown, each second primary color photon pixel group 12A may include at least two adjacent second primary color photon pixels 12, for example, may include two adjacent second primary color photon pixels 12, thereby ensuring that two adjacent pixel units 10 (for example, Figure 1 The first pixel unit P1 and the second pixel unit P2 in the image can have at least four second primary color photon pixels 12 adjacent to each other, thereby further increasing the printing area of ​​a single inkjet printing operation, further reducing the inkjet printing accuracy requirements for the inkjet printing equipment, reducing the difficulty of the inkjet printing process, and helping to reduce equipment costs. At the same time, it also reduces the number of inkjet printing operations, thereby shortening the production cycle and improving the product capacity of the production line.

[0035] In some specific embodiments, Figure 1 As shown, in each pixel unit 10, the number of third primary color photon pixels 13 can be multiple, and the multiple third primary color photon pixels 13 can be divided into a plurality of third primary color photon pixel groups 13A arranged at intervals, and a third primary color photon pixel group 13A can include one third primary color photon pixel 13 or at least two adjacent third primary color photon pixels 13.

[0036] In one example, if Figure 1 As shown, each third primary color photon pixel group 13A may include at least two adjacent third primary color photon pixels 13, for example, may include two adjacent third primary color photon pixels 13, thereby ensuring that two adjacent pixel units 10 (for example, Figure 1 The first pixel unit P1 and the second pixel unit P2 in the image can have at least four third primary color photon pixels 13 adjacent to each other, thereby further increasing the printing area of ​​a single inkjet printing operation, further reducing the inkjet printing accuracy requirements for the inkjet printing equipment, reducing the difficulty of the inkjet printing process, and helping to reduce equipment costs. At the same time, it also reduces the number of inkjet printing operations, thereby shortening the production cycle and improving the product capacity of the production line.

[0037] In this embodiment, if Figure 1 As shown, all the first primary color photon pixels 11 included in each pixel unit 10 can constitute a first primary color photon pixel group 11A. Accordingly, the second primary color photon pixels 12 and the third primary color photon pixels 13 in each pixel unit 10 can be located in the peripheral area of ​​the first primary color photon pixel group 11A in each pixel unit 10.

[0038] In a specific embodiment, Figure 1As shown, when each pixel unit 10 includes multiple second primary color photon pixel groups 12A and multiple third primary color photon pixel groups 13A, the multiple second primary color photon pixel groups 12A and the multiple third primary color photon pixel groups 13A in each pixel unit 10 can be alternately and spaced around the first primary color photon pixel group 11A in each pixel unit 10.

[0039] Specifically, if Figure 1 As shown, the multiple second primary color sub-pixel groups 12A and the multiple third primary color sub-pixel groups 13A in each pixel unit 10 may be alternately and spaced around the four side edges of the first primary color sub-pixel group 11A in each pixel unit 10. That is, when viewed from above, the multiple second primary color sub-pixel groups 12A and the multiple third primary color sub-pixel groups 13A in each pixel unit 10 may surround the first primary color sub-pixel group 11A in each pixel unit 10, thereby separating the first primary color sub-pixel groups 11A of adjacent pixel units 10.

[0040] And, as Figure 1 As shown, in each pixel unit 10, the number of the second primary color photon pixels 12 set corresponding to each side edge of the above-mentioned first primary color photon pixel group 11A can be the same, and the number of the third primary color photon pixels 13 set corresponding to each side edge of the above-mentioned first primary color photon pixel group 11A can also be the same.

[0041] Further, if Figure 1 As shown, in each pixel unit 10 , the number of the second primary color sub-pixels 12 and the second primary color sub-pixels 12 arranged corresponding to each side edge of the first primary color sub-pixel group 11A can be the same.

[0042] For example, in each pixel unit 10, Figure 2As shown, the first primary color photon pixel group 11A may include four side edges connected end to end (for example, a front edge 11A-1, a left edge 11A-3, a rear edge 11A-2, and a right edge 11A-4 connected end to end). Furthermore, in each pixel unit 10, the number of second primary color photon pixels 12 arranged corresponding to the front edge 11A-1 of the first primary color photon pixel group 11A, the number of second primary color photon pixels 12 arranged corresponding to the rear edge 11A-2 of the first primary color photon pixel group 11A, the number of second primary color photon pixels 12 arranged corresponding to the left edge 11A-3 of the first primary color photon pixel group 11A, and the number of second primary color photon pixels 12 arranged corresponding to the right edge 11A-4 of the first primary color photon pixel group 11A may all be two. Furthermore, in each pixel unit 10, the number of third primary color photon pixels 13 set corresponding to the front edge 11A-1 of the above-mentioned first primary color photon pixel group 11A, the number of third primary color photon pixels 13 set corresponding to the rear edge 11A-2 of the above-mentioned first primary color photon pixel group 11A, the number of third primary color photon pixels 13 set corresponding to the left edge 11A-3 of the above-mentioned first primary color photon pixel group 11A, and the number of third primary color photon pixels 13 set corresponding to the right edge 11A-4 of the above-mentioned first primary color photon pixel group 11A can also be two.

[0043] In a specific example, Figure 1 As shown, each pixel unit 10 may include six first primary color photon pixels 11, six second primary color photon pixels 12, and six third primary color photon pixels 13. Specifically, the six first primary color photon pixels 11 in each pixel unit 10 may be arranged in two rows and three columns and located in the middle area of ​​each pixel unit 10. The six second primary color photon pixels 12 and the six third primary color photon pixels 13 in each pixel unit 10 may be arranged in a manner of "two adjacent second primary color photon pixels 12 - two adjacent third primary color photon pixels 13 - two adjacent second primary color photon pixels 12 - two adjacent third primary color photon pixels 13 - two adjacent second primary color photon pixels 12 - two adjacent third primary color photon pixels 13", surrounding the six first primary color photon pixels 11 arranged in two rows and three columns in each pixel unit 10.

[0044] Specifically, if Figure 1 As shown, in the adjacent two pixel units 10 in the same column (for example, Figure 1In the first pixel unit P1 and the second pixel unit P2 in the image processing apparatus, the first side edge of one pixel unit 10 is adjacent to the second side edge of the other pixel unit 10, and the second primary color photon pixel 12 included in one pixel unit 10 at its first side edge position and the second primary color photon pixel 12 included in the other pixel unit 10 at its second side edge position can be arranged one-to-one in correspondence and adjacent to each other. Furthermore, the third primary color photon pixel 13 included in one pixel unit 10 at its first side edge position and the third primary color photon pixel 13 included in the other pixel unit 10 at its second side edge position can also be arranged one-to-one in correspondence and adjacent to each other.

[0045] Furthermore, in the same column, two adjacent pixel units 10 (for example, Figure 1 In the first pixel unit P1 and the second pixel unit P2), two adjacent second primary color photon pixels 12 of one pixel unit 10 correspond one-to-one to two adjacent second primary color photon pixels 12 of another pixel unit 10 and are arranged adjacent to each other, and two adjacent third primary color photon pixels 13 of one pixel unit 10 correspond one-to-one to two adjacent third primary color photon pixels 13 of another pixel unit 10 and are arranged adjacent to each other.

[0046] Specifically, if Figure 1 As shown, in the adjacent two pixel units 10 in the same row (for example, Figure 1 In the first pixel unit P1 and the third pixel unit P3 in the image, the third side edge of one pixel unit 10 is adjacent to the fourth side edge of another pixel unit 10, and the second primary color photon pixel 12 included in one pixel unit 10 at its third side edge position and the second primary color photon pixel 12 included in the other pixel unit 10 at its fourth side edge position can be arranged one-to-one in correspondence and adjacent to each other. Furthermore, the third primary color photon pixel 13 included in one pixel unit 10 at its third side edge position and the third primary color photon pixel 13 included in the other pixel unit 10 at its fourth side edge position can also be arranged one-to-one in correspondence and adjacent to each other.

[0047] Furthermore, in the same row of two adjacent pixel units 10 (for example, Figure 1 In the first pixel unit P1 and the third pixel unit P3), two adjacent second primary color photon pixels 12 of one pixel unit 10 correspond one-to-one to two adjacent second primary color photon pixels 12 of another pixel unit 10 and are arranged adjacent to each other, and two spaced-apart third primary color photon pixels 13 of one pixel unit 10 correspond one-to-one to two spaced-apart third primary color photon pixels 13 of another pixel unit 10 and are arranged adjacent to each other.

[0048] It should be noted that, the more primary color sub-pixels 11 / 12 / 13 a pixel unit 10 includes, the more conducive it is to achieving a high resolution of the above-mentioned display panel.

[0049] In this embodiment, the first primary color photon pixel 11, the second primary color photon pixel 12, and the third primary color photon pixel 13 are used to emit light of different colors, and the first primary color photon pixel 11 can be specifically any one of a red photon pixel, a green photon pixel, and a blue photon pixel, the second primary color photon pixel 12 can be specifically any one of a red photon pixel, a green photon pixel, and a blue photon pixel, and the third primary color photon pixel 13 can be specifically any one of a red photon pixel, a green photon pixel, and a blue photon pixel. In a specific example, as Figure 1 As shown, the first primary color photon pixel 11, the second primary color photon pixel 12 and the third primary color photon pixel 13 can be a blue light sub-pixel, a red light sub-pixel and a green light sub-pixel, respectively. That is, the first primary color photon pixel 11, the second primary color photon pixel 12 and the third primary color photon pixel 13 can be used to emit blue light, red light and green light, respectively.

[0050] In the above embodiment, the shapes of the first primary color photon pixel 11, the second primary color photon pixel 12 and the third primary color photon pixel 13 may be the same or different, and the shapes of the first primary color photon pixel 11, the second primary color photon pixel 12 and the third primary color photon pixel 13 may be specifically closed geometric shapes such as diamond, circle, ellipse, square, rectangle or polygon. In one example, the shapes of the second primary color photon pixel 12 and the third primary color photon pixel 13 may be the same, for example, both are square (such as Figure 1 ), or both are rectangular (as shown Figure 3 In some specific embodiments, the sizes of the second primary color photon pixel 12 and the third primary color photon pixel 13 may also be the same.

[0051] Specifically, if Figure 3 As shown, in the embodiment where the second primary color photon pixel 12 and the third primary color photon pixel 13 are both rectangular in shape, the long side of the second primary color photon pixel 12 in each pixel unit 10 and the long side of the third primary color photon pixel 13 in each pixel unit 10 can be arranged around the first primary color photon pixel group 11A in each pixel unit 10.

[0052] In this embodiment, if Figure 1 As shown, two adjacent pixel units 10 (for example, Figure 1 The first pixel unit P1 and the second pixel unit P2 in the embodiment can be identical and located in the same row and adjacent to each other (for example, Figure 1 One pixel unit 10 in the first pixel unit P1 and the third pixel unit P3 may be mirror-symmetrical to the other pixel unit 10. In other embodiments, such as Figure 3 As shown, one of the two adjacent pixel units 10 located in the same row can be completely overlapped with the other pixel unit 10 after being rotated 180 degrees. In other embodiments, the two adjacent pixel units 10 located in the same row can also be completely identical.

[0053] In some specific embodiments, Figure 4 As shown, the display panel may further include a substrate 20 and at least one dam 30 located on the substrate 20. The plurality of pixel units 10 may be arranged in rows and columns on the substrate 20, and each dam may be used to separate adjacent first primary color photon pixels 11 from other primary color photon pixels (i.e., second primary color photon pixels 12 and third primary color photon pixels 13), or to separate adjacent second primary color photon pixels 12 from other primary color photon pixels (i.e., first primary color photon pixels 11 and third primary color photon pixels 13), or to separate adjacent third primary color photon pixels 13 from other primary color photon pixels (i.e., first primary color photon pixels 11 and second primary color photon pixels 12).

[0054] It can be understood that when the area where the adjacent multiple primary color photon pixels with the same luminous color (for example, the first primary color photon pixel 11, the second primary color photon pixel 12 or the third primary color photon pixel 13) in the above-mentioned display panel are located is taken as a whole printing area for inkjet printing of the luminescent material to form the luminescent functional layer of the adjacent multiple primary color photon pixels with the same luminous color (for example, the first primary color photon pixel 11, the second primary color photon pixel 12 or the third primary color photon pixel 13) in the above-mentioned display panel, the cofferdam 30 located around the area where the adjacent multiple primary color photon pixels with the same luminous color (for example, the first primary color photon pixel 11, the second primary color photon pixel 12 or the third primary color photon pixel 13) in the above-mentioned display panel are located can limit the ink to flow and spread within the area where the adjacent multiple primary color photon pixels with the same luminous color are located, so as to prevent the ink from flowing to the area where other primary color photon pixels are located, thereby preventing the occurrence of optical crosstalk between adjacent primary color photon pixels with different luminous colors.

[0055] Furthermore, in a specific implementation, the dam 30 for separating the adjacent first primary color photon pixel 11 from the other primary color photon pixels, the dam 30 for separating the adjacent second primary color photon pixel 12 from the other primary color photon pixels, and the dam 30 for separating the adjacent third primary color photon pixel 13 from the other primary color photon pixels can be connected together (e.g., Figure 4 As shown), they can also be arranged at intervals from each other.

[0056] In a specific embodiment, the above-mentioned substrate 20 can be an array substrate including a thin film transistor (TFT) device, and the array substrate can specifically include a substrate and a TFT device layer stacked in the longitudinal direction Z. The above-mentioned pixel unit 10 and the cofferdam 30 can be arranged on the side of the TFT device layer away from the substrate, and the above-mentioned pixel unit 10 can be electrically connected to the TFT device layer, wherein the TFT device layer can control the light emission of the above-mentioned pixel unit.

[0057] Specifically, the TFT device layer may include a plurality of gate lines, a plurality of data lines, and a plurality of pixel regions defined by the plurality of gate lines and the plurality of data lines disposed on a substrate. The pixel units 10 may be formed on corresponding pixel regions in an array substrate, and the plurality of pixel units 10 may correspond one-to-one to the plurality of pixel regions.

[0058] It should be noted that the pixel structure adopted by the above-mentioned display panel in this embodiment designs multiple primary color photon pixels of the same luminous color together, which not only increases the number of nozzles corresponding to the primary color photon pixels of the same luminous color when inkjet printing the sub-pixels in the above-mentioned display panel and reduces the requirements for inkjet printing accuracy, but also makes it possible to print sub-pixels with different arrangement directions without turning the substrate or inkjet printing equipment when two types of display panels of different sizes are mixed and designed on the same substrate, thereby improving production efficiency and increasing overall output.

[0059] As can be seen from the above, the display panel in this embodiment, by making the pixel units in the display panel include at least one first primary color photon pixel, and at least one second primary color photon pixel and at least one third primary color photon pixel arranged around the at least one first primary color photon pixel, and making the at least one second primary color photon pixel included in one pixel unit of two adjacent pixel units adjacent to the at least one second primary color photon pixel included in the other pixel unit, and / or making the at least one third primary color photon pixel included in one pixel unit of two adjacent pixel units adjacent to the at least one third primary color photon pixel included in the other pixel unit, so that the luminescent materials of adjacent primary color photon pixels with the same luminescent color can be formed as a whole through inkjet printing, which is beneficial to reducing the difficulty of printing the luminescent material, and further, even if the inkjet printing accuracy is not high enough, a high-resolution display panel can still be prepared, which is beneficial to the mass production of the product.

[0068] In some specific embodiments, each pixel region may include multiple first sub-pixel regions, and the multiple first sub-pixel regions may be arranged in rows and columns and disposed adjacent to each other. Accordingly, in order to form the first primary color sub-pixel, the above S12 may specifically include:
