AI Technical Summary
The existing high-resolution OLED display panels have different solvent saturation steam pressures in the peripheral and central areas, resulting in uneven film thickness of the sub-pixel luminescent layer. It is necessary to set virtual pixels in the non-display area to maintain uniformity, but this increases the border width and violates the narrow border design.
By setting virtual pixels with at least two outer contours in the non-display area, the ink carrying capacity is improved, the number of virtual pixels is reduced, and the border width is reduced.
While maintaining the uniformity of the sub-pixel film layer, it reduces the frame width of the display panel, meets the design requirements of narrow frames, and improves printing accuracy, so that it matches the high-resolution display panel.

Obviously, the drawings described below are only some embodiments of the present application, and those skilled in the art can obtain other drawings based on these drawings without creative work.
[0027] In order to more completely understand the present application and its beneficial effects, the following description will be given in conjunction with the accompanying drawings, wherein the same figure numbers represent the same parts in the following description.

[0029] Figure 2 for Figure 1 Enlarged view of the middle area M;
[0030] Figure 3 A diagram of the film layers of a display panel provided in an embodiment of the present application. DETAILED DESCRIPTION
[0031] 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.
[0032] See also Figures 1 to 3 The present application proposes a display panel 100, which includes a display area AA and a non-display area NA arranged on at least one side of the display area AA, and a plurality of sub-pixels PX arranged along a first direction X and a second direction Y are arranged in the display area AA.
[0033] In this embodiment, a virtual pixel portion 80 including a plurality of virtual pixels is disposed in the non-display area NA. The plurality of virtual pixels and corresponding sub-pixels PX are arranged in parallel in the first direction X, and in the top view direction of the display panel 100, the plurality of virtual pixels have at least two outer contours.
[0034] For the OLED display panel with a retaining wall, after the ink is printed at the position of the sub-pixel PX in the display area AA, due to the large difference between the saturated vapor pressure of the solvent of the sub-pixel PX in the peripheral area of the display panel 100 and the saturated vapor pressure of the solvent of the sub-pixel PX in the central area of the display panel 100, the evaporation rate of the solvent in the peripheral area is slower than the evaporation rate of the solvent in the central area; at the same time, the ink in the peripheral area is affected by the capillary action of the pixel layer 30 and the surface of the anode layer, so that the ink in the central area continues to move toward the peripheral area, resulting in a difference in the film thickness of the light-emitting layer in the sub-pixel PX in the central area and the sub-pixel PX in the peripheral area.
[0035] In order to solve this technical problem, virtual pixels are currently set in the non-display area NA of the display panel 100, and sub-pixels PX with uneven thickness are set in the non-display area NA to ensure the uniformity of the film layer of the sub-pixels PX in the display area AA. The setting of the virtual pixels increases the border width of the display panel 100, which is contrary to the narrow border design of the current display panel 100. At the same time, the present application changes the outer contour of the virtual pixels in the non-display area NA so that the virtual pixels in the non-display area NA have at least two outer contours. The increase in the types of outer contours improves the ink carrying capacity, reduces the number of virtual pixels, and reduces the border width of the display panel 100.
[0036] Secondly, for current high-resolution OLED display panels, such as 8K or 16K display panels, the number of sub-pixels PX increases, which reduces the ink volume required for a single sub-pixel PX and the spacing between adjacent sub-pixels PX; while the minimum printing volume of the current printing device is greater than the ink volume required for a single sub-pixel PX, and the minimum moving spacing of the printing device is greater than the spacing between adjacent sub-pixels PX, resulting in the printing accuracy of the current printing device not matching the current high-resolution display panel 100.
[0037] In this embodiment, the plurality of sub-pixels PX located in the display area AA may include a plurality of first pixel groups PXL1 and a plurality of second pixel groups PXL2, the plurality of first pixel groups PXL1 include a plurality of first pixel units RU1 arranged along a first direction X, the plurality of second pixel groups PXL2 are arranged at intervals with the plurality of first pixel groups PXL1 along a second direction Y, and the second pixel groups PXL2 include a plurality of second pixel units RU2 arranged along the first direction X.
[0038] In this embodiment, the first pixel unit RU1 and the second pixel unit RU2 each include at least three sub-pixels PX with different luminous colors arranged along the second direction Y, and the sub-pixels PX in the first pixel unit RU1 and the second pixel unit RU2 are arranged in a mirror image.
[0039] In this embodiment, in the second direction Y, a first retaining wall 30a is disposed between two adjacent sub-pixels PX with the same luminous color, and a second retaining wall 30b is disposed between two adjacent sub-pixels PX with different luminous colors, and the thickness of the first retaining wall 30a is less than the thickness of the second retaining wall 30b.
[0040] The increase in the resolution of the display panel 100 reduces the ink volume required for a single sub-pixel PX and the spacing between adjacent sub-pixels PX, while the minimum printing volume of the current printing device is greater than the ink volume required for a single sub-pixel PX, and the minimum moving spacing of the printing device is greater than the spacing between adjacent sub-pixels PX, resulting in the printing accuracy of the current printing device not matching the current high-resolution display panel 100; the sub-pixels PX in two adjacent pixel units of the present application are arranged in a mirror-image setting, and a thin retaining wall structure is set between two adjacent sub-pixels PX with the same luminous color, so that adjacent sub-pixels PX with the same luminous color can be printed by the same drop of ink, while also increasing the spacing between adjacent sub-pixels PX with different luminous colors, thereby reducing the printing accuracy required for the high-resolution display panel 100, so that the printing accuracy of the current printing device matches the current high-resolution display panel 100, and reducing the preparation cost of the product.
[0041] It should be noted that the first pixel unit RU1 and the second pixel unit RU2 of the present application may both include a first sub-pixel PX1, a second sub-pixel PX2, and a third sub-pixel PX3 arranged along the second direction Y and having different luminous colors, and the luminous colors of the first sub-pixel PX1, the second sub-pixel PX2, and the third sub-pixel PX3 may be different ones of red, green, and blue, respectively; in the following embodiments, the luminous color of the first sub-pixel PX1 is red, the luminous color of the second sub-pixel PX2 is blue, and the luminous color of the third sub-pixel PX3 is green as an example for explanation.

Optionally, the non-display area NA surrounds the display area AA, so that the display area AA is surrounded by the non-display area NA. The display area AA is an area in the display panel 100 for performing a display function, and a plurality of sub-pixels PX are disposed therein to realize the display function. The non-display area NA may be a frame area of the display panel 100, and a functional component may be disposed therein to assist the sub-pixels PX in the display area AA to perform display.
[0044] See also Figure 1 The lower side of the display area AA may be provided with a binding terminal, which may be connected to an external circuit, and transmits the signal input by the external circuit to the data line, thereby driving the display panel 100 to display the picture.

[0052] It should be noted that, since the light-emitting layer 402 of the present application is prepared using an inkjet printing process, in order to reduce the accuracy of inkjet printing, the first pixel definition layer 310 of the present application may include a plurality of third retaining walls 30c that are staggered horizontally and vertically, and the third retaining walls 30c that are staggered horizontally and vertically enclose a plurality of pixel openings corresponding to sub-pixels. The second pixel definition layer 320 includes a plurality of second retaining walls 30b in a horizontal or vertical direction, and the plurality of sub-pixels between two adjacent second retaining walls 30b have the same color, so that in the inkjet printing process, the plurality of sub-pixels between two adjacent second retaining walls 30b can be printed simultaneously along the arrangement direction of the second retaining walls 30b, thereby reducing the accuracy of inkjet printing and improving the process efficiency.
[0053] It should be noted that the first pixel definition layer 310 and the second pixel definition layer 320 of the present application can be formed in one process, that is, the film layers of the first pixel definition layer 310 and the second pixel definition layer 320 are formed at the same time, and the first pixel definition layer 310 and the second pixel definition layer 320 are patterned in the same mask, so that the first pixel definition layer 310 forms a plurality of third retaining walls 30c, and the second pixel definition layer 320 forms a plurality of second retaining walls 30b. For example, the present application may include a plurality of third retaining walls 30c extending along the second direction Y and arranged along the first direction X, and a plurality of second retaining walls 30b extending along the first direction X and arranged along the second direction Y. For details, please refer to the attached figure of the present application. Figure 2 .
[0054] It should be noted that the first retaining wall 30 a of the present application can also be prepared in the patterning process of the first pixel definition layer 310 , that is, the thickness of the first retaining wall 30 a and the thickness of the third retaining wall 30 c can be equal.
[0055] In this embodiment, since the second barrier wall 30 b mainly serves to isolate sub-pixels of different colors, the thickness of the second barrier wall 30 b of the present application may be greater than the thickness of the third barrier wall 30 c.
[0056] It should be noted that the display panel 100 also includes a supporting layer (not shown) integrally arranged with the pixel layer 30, and the supporting layer is arranged on the surface of the second pixel definition layer 320 away from the first pixel definition layer 310, and the supporting layer and the pixel layer 30 can be formed in the same photomask process, and the supporting layer can be used to support the mask plate.

[0060] See also Figure 3 The color filter layer 60 includes a plurality of color resists 610 and light shielding units 620 disposed on both sides of the color resists 610 , and one color resist 610 corresponds to one light-emitting pixel.
[0061] See also Figure 3 The cover layer 70 is disposed on a side of the color filter layer 60 away from the base substrate 10 . The cover layer 70 may be a glass cover or may be formed directly on the color filter layer 60 .
[0062] See also Figure 2 Since the sub-pixels PX in the first pixel unit RU1 and the second pixel unit RU2 are arranged in a mirror-image manner, for example, the first pixel unit RU1 is arranged in a manner of the first sub-pixel PX1, the second sub-pixel PX2 and the third sub-pixel PX3, and the second pixel unit RU2 is arranged in a manner of the third sub-pixel PX3, the second sub-pixel PX2 and the first sub-pixel PX1, therefore, the first sub-pixel PX1 of the first pixel unit RU1 of the present application is arranged adjacent to the first sub-pixel PX1 in an adjacent second pixel unit RU2, and the third sub-pixel PX3 of the first pixel unit RU1 is arranged adjacent to the third sub-pixel PX3 in another adjacent second pixel unit RU2.
[0063] exist Figure 2 In the structure, since the plurality of first pixel groups PXL1 include a plurality of first pixel units RU1 arranged along the first direction X, and the second pixel group PXL2 includes a plurality of second pixel units RU2 arranged along the second direction Y, the plurality of sub-pixels PX in the first direction X are all sub-pixels PX of the same luminous color.
[0064] exist Figure 2In the structure, a second retaining wall 30b is arranged between two adjacent sub-pixels PX with different luminous colors, that is, the second retaining wall 30b of the present application is arranged between the first sub-pixel PX1 and the second sub-pixel PX2, and between the second sub-pixel PX2 and the third sub-pixel PX3; at the same time, since a first retaining wall 30a is arranged between two adjacent sub-pixels PX with the same luminous color, that is, the first retaining wall 30a of the present application can extend along the first direction X, and the first retaining wall 30a is arranged between two adjacent first sub-pixels PX1 and between two adjacent third sub-pixels PX3.
[0065] exist Figure 2 In the structure, for two adjacent rows of first sub-pixels PX1 or two adjacent rows of third sub-pixels PX3, a first blocking wall 30a is set between two adjacent first sub-pixels PX1 or third sub-pixels PX3 in the second direction Y, a third blocking wall 30c is set between two adjacent first sub-pixels PX1 or third sub-pixels PX3 in the first direction X, and a second blocking wall 30b is set between two adjacent rows of first sub-pixels PX1 or third sub-pixels PX3 and an adjacent row of second sub-pixels PX2, and because the thickness of the second blocking wall 30b is greater than the thickness of the first blocking wall 30a and the third blocking wall 30c, When the third sub-pixel PX3 is printed, two adjacent rows of first sub-pixels PX1 or third sub-pixels PX3 can be printed simultaneously, which is equivalent to reducing the number of printing times of the first sub-pixel PX1 and the third sub-pixel PX3, thereby saving printing efficiency; at the same time, two adjacent rows of first sub-pixels PX1 or third sub-pixels PX3 can be printed simultaneously, which increases the minimum ink volume required for the sub-pixels PX, and also increases the printing spacing between adjacent sub-pixels PX to be printed in the second direction Y, thereby reducing the printing accuracy required for the high-resolution display panel 100, so that the printing accuracy of the current printing device matches the current high-resolution display panel 100.
[0066] In this embodiment, in order to ensure the uniformity of printing of two adjacent rows of first sub-pixels PX1 or third sub-pixels PX3, the thickness of the third barrier wall 30c of the present application can be less than or equal to the thickness of the first barrier wall 30a. For example, the thickness of the third barrier wall 30c can be equal to the thickness of the first barrier wall 30a.
[0067] In the present embodiment, since the luminous color of the second sub-pixel PX2 is blue, and the luminous efficiency of the blue sub-pixel is lower than that of the red sub-pixel and the green sub-pixel, the present application can increase the area of the second sub-pixel PX2, for example, the area of the second sub-pixel PX2 is larger than the area of the first sub-pixel PX1, and the area of the second sub-pixel PX2 is larger than the area of the third sub-pixel PX3, so that the luminous efficiencies of the first sub-pixel PX1, the second sub-pixel PX2 and the third sub-pixel PX3 can be close, thereby improving the display uniformity of the display panel 100.
[0068] See also Figure 2 The virtual pixel unit 80 may include a plurality of first shape pixels 810 and a plurality of second shape pixels 820; for example, in the present application, the outer contour of the first shape pixel 810 is a rectangle, and the outer contour of the second shape pixel 820 is a polygon or a circle.
[0069] For example, in Figure 2 In the structure, the outer contour of the first shape pixel 810 is a rectangle, and the outer contour of the second shape pixel 820 is a circle. In the present application, multiple first shape pixels 810 are arranged in parallel along the second direction Y, and multiple second shape pixels 820 are arranged in a staggered manner along the second direction Y. The multiple first shape pixels 810 can be arranged adjacent to the display area AA, and the multiple second shape pixels 820 can be arranged on the side of the multiple first shape pixels 810 away from the display area AA.
[0070] In this embodiment, a first shape pixel 810 is arranged adjacent to two first sub-pixels PX1, a first shape pixel 810 is arranged adjacent to a second sub-pixel PX2, and a first shape pixel 810 is arranged adjacent to two third sub-pixels PX3; for example, a plurality of first shape pixels 810 may include a first red pixel 810r, a first blue pixel 810b and a first green pixel 810g, and the first red pixel 810r, the first blue pixel 810b and the first green pixel 810g are arranged along the second direction Y, a first red pixel 810r may be arranged adjacent to two first sub-pixels PX1, a first blue pixel 810b may be arranged adjacent to a second sub-pixel PX2, and a first green pixel 810g may be arranged adjacent to two third sub-pixels PX3.
[0071] See also Figure 2 A plurality of first shape pixels 810 are arranged adjacent to the sub-pixels PX in the display area AA, and in order to allow the ink in the sub-pixels PX in the display area AA to enter the corresponding first shape pixels 810, a third retaining wall 30c can be arranged between the first shape pixels 810 of the present application and the adjacent sub-pixels PX in the display area AA.
[0072] At the same time, the area of each first-shape pixel 810 can be equal or partially equal, for example, the area of the first blue pixel 810b can be equal to the area of the second sub-pixel PX2, the area of the first red pixel 810r can be equal to the area of the two first sub-pixels PX1, and the area of the first green pixel 810g can be equal to the area of the two third sub-pixels PX3; or, the areas of the first red pixel 810r, the first blue pixel 810b and the first green pixel 810g are all equal.
[0073] See also Figure 2, a plurality of second shape pixels 820 corresponding to the plurality of second sub-pixels PX2 are disposed close to the display area AA, and a plurality of second shape pixels 820 corresponding to the plurality of first sub-pixels PX1 and the plurality of third sub-pixels PX3 are disposed away from the display area AA.
[0074] For example, the plurality of second shape pixels 820 may include a second red pixel 820r, a second blue pixel 820b and a second green pixel 820g, the plurality of second blue pixels 820b may be arranged close to the display area AA, the plurality of second red pixels 820r and the plurality of second green pixels 820g may be arranged away from the display area AA; at the same time, the plurality of first blue pixels 810b may be arranged at intervals in the second direction Y, the plurality of second red pixels 820r and the plurality of second green pixels 820g may be arranged at intervals in the second direction Y.
[0075] In this embodiment, the virtual pixel portion 80 may further include a plurality of connecting segments 830, wherein the connecting segment 830 is disposed between two adjacent second shape pixels 820 corresponding to the second sub-pixel PX2, and the two ends of the connecting segment 830 are respectively connected to the first shape pixel 810 and the second shape pixel 820 corresponding to the first sub-pixel PX1 or the third sub-pixel PX3.
[0076] For example, in Figure 2 In the structure, since the distance between two adjacent second blue pixels 820b in the second direction Y is too small, the second red pixel 820r or the second green pixel 820g cannot be set between the two adjacent second blue pixels 820b. Therefore, the second red pixel 820r of the present application can be connected to the first red pixel 810r through a connecting segment 830, and the second green pixel 820g can be connected to the first green pixel 810g through another connecting segment 830, so that the ink in the first shape pixel 810 flows into the corresponding second shape pixel 820.
[0077] It should be noted that, in order to facilitate the circulation of ink, no corresponding retaining wall structure is provided between the first shape pixel 810 and the second shape pixel 820 , that is, the first shape pixel 810 and the second shape pixel 820 are connected.
[0078] It should be noted that since the outer contour of the second shape pixel 820 of the present application is circular, compared with the virtual pixel of the square structure in the prior art, the circular structure has a greatly increased ink carrying capacity, and there is no need to add additional virtual pixels, thereby reducing the number of virtual pixels; for example, the display area AA of the prior art is usually provided with 8 virtual pixels, while the setting of the first shape pixel 810 and the second shape pixel 820 of the present application only occupies the width of the original 3 virtual pixels, thereby reducing the width of the border occupied by the virtual pixel and realizing the narrow border design of the display panel 100.
[0079] It should be noted that the ink of the present application only flows in the first direction X, and therefore the virtual pixels of the present application are only arranged on both sides of the display area AA in the first direction X.
[0080] It should be noted that relevant virtual pixels are also arranged on both sides of the display area AA in the second direction Y, but the virtual pixels in the second direction Y are not used to carry excess ink in the display area AA.
[0081] In this embodiment, in order to avoid interference between inks of different colors, a fourth barrier wall 30d may be set between two adjacent virtual pixels in the second direction Y, and the thickness of the fourth barrier wall 30d is the same as the thickness of the second barrier wall 30b; for example, a fourth barrier wall 30d may be set between two adjacent first shape pixels 810.
[0082] The present application also proposes a display device, which includes the above display panel. It should be noted that the display device of the present application can be any product or component with display function, such as a mobile phone, a tablet computer, a television, a monitor, a laptop computer, a digital photo frame, a navigator, etc.
