Compared with liquid crystal display panels, organic light-emitting diode (OLED) display panels have advantages of being thinner and lighter, better display effect, higher resolution, wider color gamut, lower power consumption, and being able to achieve flexible display. The OLED display panels have developed rapidly in recent years and have become a preferred type of display panels for mobile terminals.
In related art, one of preparation methods of pixel unit arrays of the OLED display panels is inkjet printing.

At present, higher requirements for a resolution of the OLED display panels have been put forward by users. However, limited by a machine accuracy of an existing inkjet printing process, it is difficult for the OLED display panels to balance layout areas of pixel units on a basis of ensuring the resolution, resulting in a technical problem that the OLED display panels with high resolution has a greater printing difficulty. The technical problem urgently needs to be solved.

A display device provided by the present application includes a housing and the display panel mentioned above. The housing includes an accommodating space. The display panel is disposed inside the accommodating space.
The beneficial effects of the present application are illustrated as follows. The present application provides a display panel and a display device. The display panel adopts a specific arrangement of pixel units, so that the adjacent first pixel units are misaligned along the first direction and the second direction, the first pixel units of one of the first pixel unit rows at least partially overlap with the second pixel units and the third pixel units of the adjacent second pixel unit row along the first direction, and the first pixel units of one of the first pixel unit columns at least partially overlap with the second pixel units and the third pixel units of the adjacent second pixel unit column along the first direction. On the basis of ensuring a resolution of the display panel, a layout area of the pixel units is increased in limited layout space, thereby reducing a process difficulty of forming the first pixel units, the second pixel units, and the third pixel units of the display panel by inkjet printing, and improving a production yield.
One of the second pixel unit rows 102 is arranged between every adjacent two of the first pixel unit rows 101. The first pixel units 21 in each of the first pixel unit rows 101 are misaligned with the first pixel units 21 of an adjacent first pixel unit row 101 along the first direction X. A projection of the first pixel units 21 of one of the first pixel unit rows 101 at least partially overlaps with a projection of the second pixel units 22 and the third pixel units 23 of an adjacent second pixel unit row 102 along the first direction X.
One of the second pixel unit columns 202 is arranged between every adjacent two of the first pixel unit columns 201. The first pixel units 21 in each of the first pixel unit columns 201 are misaligned with the first pixel units 21 of an adjacent first pixel unit column 201 along the second direction Y. A projection of the first pixel units 21 of one of the first pixel unit columns 201 at least partially overlaps with a projection of the second pixel units 22 and the third pixel units 23 of an adjacent second pixel unit column 202 along the second direction Y.
In the display panel provided by the present application, since the first pixel units 21 in each of the first pixel unit rows 101 are misaligned with the first pixel units 21 of the adjacent first pixel unit row 101 along the first direction X, and the first pixel units 21 in each of the first pixel unit columns 201 are misaligned with the first pixel units 21 of the adjacent first pixel unit column 201 along the second direction Y, so that the display panel adopts an arrangement in which the first pixel units 21 are misaligned along the first direction X and the second direction Y. On a basis of ensuring a layout number of the first pixel units 21 and a resolution of the display panel, the first pixel units 21 each has a larger size along the first direction X and the second direction Y, thereby reducing a difficulty of printing the first pixel units 21, and reserving layout space for the second pixel units 22 and the third pixel units 23.
Furthermore, one of the second pixel unit rows 102 is arranged between every adjacent two of the first pixel unit rows 101. The projection of the first pixel units 21 of one of the first pixel unit rows 101 at least partially overlaps with the projection of the second pixel units 22 and the third pixel units 23 of the adjacent second pixel unit row 102 along the first direction X. One of the second pixel unit columns 202 is arranged between every adjacent two of the first pixel unit columns 201. The projection of the first pixel units 21 of one of the first pixel unit columns 201 at least partially overlaps with the projection of the second pixel units 22 and the third pixel units 23 of the adjacent second pixel unit column 202 along the second direction Y. So such, the display panel adopts an arrangement in which the second pixel units 22 and the third pixel units 23 are obliquely arranged, so that on a basis of ensuring a layout number of the second pixel units 22 and the third pixel units 23 and the resolution of the display panel, the second pixel units 22 and the third pixel units 23 can more fully utilize the space along the first direction X and the second direction Y, and a size of each of the second pixel units 22 and the third pixel units 23 is widened, thereby reducing a difficulty of printing the second pixel units 22 and the third pixel units 23.
In some embodiments of the present application, a minimum pitch between the first pixel units and the second pixel units is defined as a, and a minimum pitch between the first pixel units and the third pixel units is defined as b. The a is equal to the b and greater than or equal to a preset value.
In the display panel provided by the present application, the preset value ranges from 10 μm to 15 μm, such as 12 μm. Specifically, limited by accuracy requirements of inkjet printing devices, the minimum pitch a between the first pixel units 21 and the second pixel units 22 should be no less than the preset value, and the minimum pitch b between the first pixel units 21 and the third pixel units 23 should be no less than the preset value. In the present application, the two pixel units and the third pixel units 23 are obliquely arranged, so that on the basis of ensuring that both the a and the b are greater than or equal to the preset value, the display panel having the resolution that meets requirements of users and having larger sizes of the pixel units can be manufactured by using the inkjet printing devices with an existing design accuracy.
In some embodiments of the present application, a periphery of each of the first pixel units 21 is provided with two second pixel units 22 and two third pixel units 23, and the two second pixel units 22 and the two third pixel units 23 are adjacent to a corresponding one of the first pixel units 2. An area of at least one of each of the two second pixel units 22 and each of the two third pixel units 23 is greater than an area of the corresponding one of the first pixel units 21.
In the display panel provided by the present application, the area of at least one of each of the two second pixel units 22 and each of the two third pixel units 23 is greater than the area of the corresponding one of the first pixel units 21. That is, the first pixel units 21 are not pixel units having the largest sizes among three types of pixel units. In the present application, the first pixel units 21 having small or medium sizes are used as center pixel units, and the two second pixel units 22 and the two third pixel units 23 surround the periphery of the corresponding one of the first pixel units 21, so that an arrangement density of the three types of pixel units is largest, and the resolution of the display panel is further improved.
In some embodiments of the present application, the two second pixel units 22 are arranged symmetrically about one of diagonal lines of the corresponding one of the first pixel units 21, and the two third pixel units 23 are arranged symmetrically about the other one of diagonal lines of the corresponding one of the first pixel units 21.
In the display panel provided by the present application, the first pixel units 21, the second pixel units 22, and the third pixel units 23 are all rectangular-shaped or quasi-rectangular-shaped. Each type of the pixel units each has two diagonal lines. In the present application, the two second pixel units 22 are arranged symmetrically about one of diagonal lines of the corresponding one of the first pixel units 21, and the two third pixel units 23 are arranged symmetrically about the other one of diagonal lines of the corresponding one of the first pixel units 21, so that distribution of relative positions of the second pixel units 22 and the first pixel units 21 can be more regular, and distribution of relative positions of the third pixel units 23 and the first pixel units 21 can be more regular, which is beneficial to improving an alignment accuracy and printing efficiency of inkjet printing.
In the display panel provided by the present application, the area of each of the first pixel units 21 in each of the two rectangular pixel partitions is equal, the area of each of the second pixel units 22 in each of the two rectangular pixel partitions is equal, and the area of each of the third pixel units 23 in each of the two rectangular pixel partitions is equal, so that an effective light-emitting area of each of the first pixel units 21 in each of the rectangular pixel partitions is equal, an effective light-emitting area of each of the second pixel units 22 in each of the rectangular pixel partitions is equal, and an effective light-emitting area of each of the third pixel units 23 in each of the rectangular pixel partitions is equal, so that a display brightness of each of the rectangular pixel partitions is more uniform, which is beneficial to improving display uniformity of different areas of the display panel and improving the display effect.
In some embodiments of the present application, each of the first pixel units 21 includes two first pixel sub-units 211 independently emitting light, and areas of the two first pixel sub-units 211 in corresponding rectangular pixel partitions are equal. Each of the second pixel units 22 includes two second pixel sub-units 221 independently emitting light, and areas of the two second pixel sub-units 221 in corresponding rectangular pixel partitions are equal. Each of the third pixel units 23 includes two third pixel sub-units 231 independently emitting light, and areas of the two third pixel sub-units 231 in corresponding rectangular pixel partitions are equal.
In the display panel provided by the present application, since each of the first pixel units 21 includes the two first pixel sub-units 211 independently emitting light, and the areas of the two first pixel sub-units 211 in corresponding rectangular pixel partitions are equal, each of the rectangular pixel partitions can independently perform display functions on a basis that the display brightness of the two rectangular pixel partitions corresponding to the two first pixel sub-units 211 can be more uniform when displayed simultaneously, thereby greatly improving the resolution of the display panel.
In the display panel provided by the present application, each of the second pixel units 22 includes the two second pixel sub-units 221 independently emitting light, and the areas of the two second pixel sub-units 221 in corresponding rectangular pixel partitions are equal, so that each of the rectangular pixel partitions can independently perform display functions on a basis that the display brightness of the two rectangular pixel partitions corresponding to the two second pixel sub-units 221 can be more uniform when displayed simultaneously, thereby greatly improving the resolution of the display panel.
In the display panel provided by the present application, each of the third pixel units 23 includes the two third pixel sub-units 231 independently emitting light, and the areas of the two third pixel sub-units 231 in corresponding rectangular pixel partitions are equal, so that each of the rectangular pixel partitions can independently perform display functions on a basis that the display brightness of the two rectangular pixel partitions corresponding to the two third pixel sub-units 231 can be more uniform when displayed simultaneously, thereby greatly improving the resolution of the display panel.
It should be noted that in order to have a better display effect of an edge of the display panel, the pixel unit array 20 of the display panel provided by some embodiments of the present application further includes first edge pixel units 24 arranged in an edge area of the pixel unit array 20. Each of the first edge pixel units 24 may have a same structure as one of the first pixel sub-units 211 of the first pixel units 21. However, the structure of each of the first edge pixel units 24 is not limited by the present application. In other embodiments of the present application, the first edge pixel units may have a same structure as the first pixel units 21. Specifically, a part of the first edge pixel units may be set as dummy pixel units, and the dummy pixel units do not perform the display function during actual use.
In the display panel provided by the present application, each of the first dams 31 is configured to separate the two first pixel sub-units 211 of each of the first pixel units 21. Each of the second dams 32 is configured to separate the two second pixel sub-units 221 of each of the second pixel units 22. Each of the third dams 33 is configured to separate the two third pixel sub-units 231 of each of the third pixel units 23. Since the first pixel definition layer 30 is made of the hydrophilic material, a barrier effect of the first dams 31, the second dams 32, and the third dams 33 on solution forming the pixel unit array 20 in the inkjet printing process can be improved, thereby preventing the two first pixel sub-units 211 in each of the first pixel units 21 from generating crosstalk, preventing the two second pixel sub-units 221 in each of the second pixel units 22 from generating crosstalk, and preventing the third first pixel sub-units 231 in each of the third pixel units 23 from generating crosstalk.
In some embodiments of the present application, a length direction of each of the first dams 31 is parallel to a width direction of a corresponding one of the first pixel units 21, and a width of the corresponding one of the first pixel units 21 is defined as a first width. A length direction of each of the second dams 32 is parallel to a width direction of a corresponding one of the second pixel units 22, and a width of the corresponding one of the second pixel units 22 is defined as a second width. A length direction of each of the third dams 33 is parallel to a width direction of a corresponding one of the third pixel units 23, and a width of the corresponding one of the third pixel units 23 is defined as a third width. The first width, the second width, and the third width are equal.
In the display panel provided by the present application, the width of each of the first pixel units 21, the width of each of the second pixel units 22, and the width of each of the third pixel units 23 are all equal, so that printing parameters of the three types of the pixel units in the inkjet printing process and specifications of the printing devices can be more unified, which is beneficial to improving the printing efficiency and a printing yield.
In some embodiments of the present application, the second width, and the third width are each greater than 30 μm.
The display panel provided by the present application adopts a special arrangement of the pixel units, so that the first width, the second width, and the third width can be greater than 30 μm, far exceeding process parameters of the pixel units having a width of 15 μm in related art, thereby greatly reducing the printing difficulty in a preparation process of the pixel unit array 20 of the display panel, and improving the yield of the display panel.
In some embodiments of the present application, a length direction of each of the first pixel units 21 is perpendicular to the length direction of a corresponding one of the first dams 31. A length direction of each of the second pixel units 22 is perpendicular to the length direction of a corresponding one of the second dams 32. A length direction of each of the third pixel units 23 is perpendicular to the length direction of a corresponding one of the third dams 33. A length of the first pixel unit 21 is greater than a length of the second pixel unit 22 and less than a length of the third pixel unit 23. That is, an area of the first pixel unit 21 is greater than an area of the second pixel unit 22 and less than an area of the third pixel unit 23. In some embodiments, the lengths of the first pixel unit 21 and the second pixel unit 22 are both greater than 30 μm, and the length of the third pixel unit 23 is greater than 50 μm. A length of each of the first dams 31 is greater than a width of the corresponding one of the first pixel units 21, and a width of each of the first dams 31 is greater than or equal to 9 μm.
In some embodiments of the present application, the display panel further includes a second pixel definition layer 40 disposed on the substrate 10. The second pixel definition layer 40 and the first pixel definition layer 30 together form a plurality of pixel definition openings N. The first pixel sub-units 211, the second pixel sub-units 221, and the third pixel sub-units 231 are correspondingly arranged within the pixel definition openings N. The second pixel definition layer 40 is made of a hydrophobic material.
In the display panel provided by the present application, the second pixel definition layer 40 is made of the hydrophobic material to effectively prevent dripping ink from infiltrating side walls of the pixel definition openings N, which is beneficial to film formation of the ink of inkjet printing. Furthermore, the ink has a water-droplet shape on a contact surface of the hydrophobic material. Therefore, when an amount of the dripping ink is large, a probability that the ink diffuses and overflows outside the pixel defining openings N can be greatly reduced.
In some embodiments of the present application, a thickness of the second pixel-defining layer 40 is greater than a thickness of the first pixel-defining layer 30.
In some embodiments of the present application, the display panel further includes an anode layer 50 disposed on the substrate 10.

In the display panel provided by the present application, since each of the rectangular pixel partitions is provided with one third guide part 531, one second guide part 521, and one third guide part 521, positions of the first guide part 511, the second guide part 521, and the third guide part 531 can be determined by using the rectangular pixel partitions as a reference object, which is beneficial to improving the efficiency of manufacturing the display panel.

The via holes are provided below the first contact hole defining area 512, the second contact hole defining area 522, and the third contact hole defining area 532, respectively. The via holes may affect a film forming effect of the pixel unit array 20 during a film forming process, thereby affecting display quality of the display panel.
