In order to simplify the disclosure of the present application, specific example components and arrangements are described below. Of course, they are merely examples and are not intended to limit the present application. Moreover, the present application may repeat reference numerals and/or letters in the various examples, such repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed. In addition, examples of various specific processes and materials are provided herein, but one of ordinary skill in the art may recognize applications of other processes and/or use of other materials.
Referring to fig. 1, the present disclosure provides a display panel 10, the display panel 10 includes a plurality of pixel units 12 arranged in an array, each pixel unit 12 includes a first sub-pixel 122, a second sub-pixel 124 and two third sub-pixels 126 located in a virtual hexagon; the first subpixel 122 and the second subpixel 124 are adjacent, and the two third subpixels 126 are adjacent to the first subpixel 122 and the second subpixel 124; the pixel cells 12 adjacent in the column extension direction share the first sub-pixel 122 and the second sub-pixel 124, and the pixel cells 12 adjacent in the row extension direction share one third sub-pixel 126.
In the display panel 10 of the embodiment of the application, any one of the first sub-pixels 122 may form an independent pixel unit 12 with one of the second sub-pixels 124 adjacent to the first sub-pixel 122 and two of the third sub-pixels 126 adjacent to the first sub-pixel 122 and the second sub-pixel 124, so that the sub-pixels may achieve a high-resolution display effect by a low-resolution physical resolution through a color borrowing principle.
It should be noted that the pixel unit 12 refers to the smallest repeating unit that can be used to achieve the same light-emitting effect and function in the display panel 10, and the arrangement of the plurality of pixel units 12 in an array means that the centers of the plurality of pixel units 12 are staggered in at least two directions to form an array. In particular, the plurality of pixel units 12 may be arranged in an array by being staggered along two mutually perpendicular directions, in this case, the two mutually perpendicular directions may be a row extending direction and a column extending direction of the pixel units 12, respectively, the pixel units 12 arranged along the row extending direction form a pixel row, and the pixels arranged along the column extending direction form a pixel column. The rows and the columns of the pixel units 12 in the display panel 10 are opposite, and in this embodiment, the pixel units 12 arranged in rows may be the pixel units 12 arranged in columns in other embodiments, which will not be described in detail herein.
In some examples, there may be two neighboring pixel cells 12 for the current pixel cell 12 in each pixel column that are not at the beginning and end positions, the current pixel cell 12 may share the first sub-pixel 122 with one neighboring pixel cell 12, while the current pixel cell 12 may share the second sub-pixel 124 with another neighboring pixel cell 12. Accordingly, there may be two adjacent neighboring pixel cells 12 for the current pixel cell 12 that are not at the beginning and ending positions in each pixel row, and the current pixel cell 12 may share one third sub-pixel 126 of the current pixel cell 12 with one neighboring pixel cell 12, while the current pixel cell 12 may share another third sub-pixel 126 of the current pixel cell 12 with another neighboring pixel cell 12.
At this time, the first sub-pixel 122, the second sub-pixel 124 and the two third sub-pixels 126 in the pixel unit 12 which are not located at the start and end positions of the pixel row and the pixel column are all shared with the adjacent pixel unit 12, so that the display effect of high resolution can be achieved by the physical resolution of low resolution between the sub-pixels through the color borrowing principle.
In some embodiments, the first sub-pixels 122 and the second sub-pixels 124 of the plurality of pixel units 12 are alternately arranged in the row extending direction and the centers of the first sub-pixels 122 and the centers of the second sub-pixels 124 of the same row are on the same straight line; the first sub-pixels 122 and the second sub-pixels 124 of one or more pixel units 12 are alternately arranged in the column extending direction and the centers of the first sub-pixels 122 and the centers of the second sub-pixels 124 of the same column are on the same straight line.
Referring to fig. 2, in some embodiments, a distance D1 from the geometric center of each third sub-pixel 126 to the geometric center of the first sub-pixel 122 in the pixel unit 12 is equal to a distance D2 from the geometric center of the third sub-pixel 126 to the geometric center of the second sub-pixel 124.
In this way, the display panel 10 can make the third sub-pixel 126, the first sub-pixel 122 and the second sub-pixel 124 closely arranged in a predetermined rule by designing the distance between the geometric centers of the sub-pixels in the pixel unit 12, so as to reduce the distance between the adjacent pixels as much as possible.
In some embodiments, the distance D3 between the geometric center of the first sub-pixel 122 and the geometric center of the second sub-pixel 124 may be greater than the distance D1 from the geometric center of the third sub-pixel 126 to the geometric center of the first sub-pixel 122 and the distance D2 from the geometric center of the third sub-pixel 126 to the geometric center of the second sub-pixel 124, or the distance D3 between the geometric center of the first subpixel 122 and the geometric center of the second subpixel 124 may be equal to the distance D1 from the geometric center of the third subpixel 126 to the geometric center of the first subpixel 122 and the distance D2 from the geometric center of the third subpixel 126 to the geometric center of the second subpixel 124, or the distance D3 between the geometric center of the first subpixel 122 and the geometric center of the second subpixel 124 may be less than the distance D1 from the geometric center of the third subpixel 126 to the geometric center of the first subpixel 122 and the distance D2 from the geometric center of the third subpixel 126 to the geometric center of the second subpixel 124.
The first sub-pixel 122 and the second sub-pixel 124 of the embodiment of the present application are arranged in the column direction and achieve the sharing of the first sub-pixel 122 or the second sub-pixel 124 in the pixel unit 12 adjacent to the column direction, and the third sub-pixel 126 achieves the sharing of the third sub-pixel 124 in the pixel unit 12 adjacent to the row direction, it can be understood that the distance D3 between the geometric center of the first sub-pixel 122 and the geometric center of the second sub-pixel 124 may be equal to or different from the distance D1 between the geometric center of the third sub-pixel 126 and the geometric center of the first sub-pixel 122 and the distance D2 between the geometric center of the third sub-pixel 126 and the geometric center of the second sub-pixel 124. Specifically, the distance D3 between the geometric center of the first sub-pixel 122 and the geometric center of the second sub-pixel 124 may be determined according to the size of the virtual hexagon, the shape and size of the first sub-pixel 122 and the second sub-pixel 124, and the relative positions of the first sub-pixel 122, the second sub-pixel 124, and the third sub-pixel 126, and the like.
Of course, in other embodiments, the distance between the centers of the sub-pixels in the pixel unit 12 may also be the center of the light emitting color of the pixel, and is not limited herein.
In some embodiments, the virtual hexagon includes two short sides that are opposite to each other in the extending direction of the vertical column, the first sub-pixel 122 and the second sub-pixel 124 are respectively disposed along the two short sides, and the two third sub-pixels 126 are respectively disposed at two opposite corners formed by the other four sides of the virtual hexagon.
It is understood that one side of the first sub-pixel 122 may coincide with one short side of the virtual hexagon, one side of the second sub-pixel 124 may coincide with the other short side of the virtual hexagon, and the adjacent sides of the second sub-pixel 124 of the first sub-pixel 122 are respectively opposite to the two short sides of the virtual hexagon. One third sub-pixel 126 is arranged in the virtual hexagon, one corner of the third sub-pixel 126 is coincided with one of two opposite corners formed by the other four sides of the virtual hexagon, one corner of the other third sub-pixel 126 is coincided with the other of the two opposite corners formed by the other four sides of the virtual hexagon, and at the moment, the two sides of the third sub-pixel 126 forming the corresponding included angle are respectively parallel to the two sides of the virtual hexagon forming the corresponding opposite corners.
In some embodiments, the other four sides of the virtual hexagon form two opposing right angles.
Referring to fig. 2 and 3, in some embodiments, the two third sub-pixels 126 are arranged in a mirror image with respect to the center line X of the short side, or the two third sub-pixels 126 are arranged symmetrically with respect to the center O of the virtual hexagon.
In the embodiment shown in fig. 2, the two third sub-pixels 126 are arranged in a mirror image with respect to the central line X of the short side. In the embodiment of fig. 3, the two third sub-pixels 126 are symmetrically distributed with respect to the center O of the virtual hexagon.
Referring again to fig. 2, in some embodiments, a distance L1 between the first sub-pixel 122 and the second sub-pixel 124 is equal to a distance L2 between the first sub-pixel 122 and the third sub-pixel 126.
Specifically, the pitch L between the sub-pixels refers to a minimum distance between edges of the sub-pixels that are close to each other, and the distance is smaller than a distance D between centers of the two sub-pixels. The spacing L1 between the first sub-pixel 122 and the adjacent second sub-pixel 124 needs to be greater than or equal to the process limit distance, and the spacing L2 between the first sub-pixel 122 and the adjacent third sub-pixel 126 needs to be greater than or equal to the process limit distance to meet the process requirement. Also, the pitch L between the sub-pixels is generally a process-critical distance. In this way, the display panel 10 can reduce the distance between the first sub-pixel 122 and the second sub-pixel 124 to the maximum, so that the pixel opening area can be increased at the position where the first sub-pixel 122 is adjacent to the second sub-pixel 124 and the position where the first sub-pixel 122 is adjacent to the third sub-pixel 126 under the condition of the same resolution, the driving current of the display device is reduced, and the service life of the display device is further increased.
In some embodiments, a spacing L3 between the second sub-pixel 124 and the third sub-pixel 126 is equal to a spacing L1 between the first sub-pixel 122 and the third sub-pixel 126.
Similarly, under the condition of the same resolution, the pixel aperture area can be increased at the position where the second sub-pixel 124 and the third sub-pixel 126 are adjacent and the position where the first sub-pixel 122 and the third sub-pixel 126 are adjacent, so as to reduce the driving current of the display device, and further increase the lifetime of the display device.
In some embodiments, a spacing L2 between the first sub-pixel 122 and the third sub-pixel 126 is equal to a spacing L3 between the second sub-pixel 124 and the third sub-pixel 126.
Similarly, under the condition of the same resolution, the positions of the first sub-pixel 122 adjacent to the third sub-pixel 126 and the positions of the second sub-pixel 124 adjacent to the third sub-pixel 126 can increase the pixel opening area, reduce the driving current of the display device, and further increase the lifetime of the display device.
In some embodiments, the spacing L1 between the first sub-pixel 122 and the second sub-pixel 124, the spacing L2 between the first sub-pixel 122 and the third sub-pixel 126, and the spacing L3 between the second sub-pixel 124 and the third sub-pixel 126 are all equal.
At this time, L1-L2-L3 means that the pitch between any two adjacent sub-pixels is equal. Therefore, the opening area of all the sub-pixels can be further increased, the driving current of the display device is reduced, and the service life of the display device is prolonged.
In some embodiments, the first sub-pixel 122 and the second sub-pixel 124 have a hexagonal shape, and the third sub-pixel 126 has a quadrangular shape. Thus, in the display panel 10, two opposite sides of the first sub-pixel 122 among six sides are adjacent to two second sub-pixels 124, respectively, and the other four sides of the first sub-pixel 122 are adjacent to four third sub-pixels 126, respectively. Similarly, two opposite sides of the second sub-pixel 124 among six sides are respectively adjacent to the two first sub-pixels 122, and the other four sides of the second sub-pixel 124 are respectively adjacent to the four third sub-pixels 126. The third sub-pixel 126 is adjacent to the two first sub-pixels 122 at one pair of opposite sides, and the third sub-pixel 126 is adjacent to the two second sub-pixels 124 at the other pair of opposite sides.
Of course, in other embodiments, the first sub-pixel 122, the second sub-pixel 124, and the third sub-pixel 126 are not limited to the shapes discussed above, and one or more of a quadrangle, a hexagon, and an octagon may be selected according to actual needs, and are not limited in this respect.
In some embodiments, each sub-pixel may be provided with a chamfer at the edge break.
In some embodiments, the color of light emitted by the first sub-pixel 122, the color of light emitted by the second sub-pixel 124, and the color of light emitted by the third sub-pixel 126 are different from each other.
Further, the light emitted by the sub-pixels in each pixel cell 12 includes red, green, and blue light. The display panel 10 can realize normal display of a full-color image by uniform distribution of sub-pixels having different colors.
In one example, the first sub-pixel 122 emits red light, the second sub-pixel 124 emits blue light, and the third sub-pixel 126 emits green light. In another example, the first sub-pixel 122 emits blue light, the second sub-pixel 124 emits red light, and the third sub-pixel 126 emits green light.
In some embodiments, the area of the first sub-pixel 122 is larger than the area of the second sub-pixel 124, and the area of the second sub-pixel 124 is larger than the area of the third sub-pixel 126.
In particular, for an organic light emitting diode display device, since a blue light emitting material generally has the lowest light emitting efficiency and a relatively short lifetime compared to red and green, a blue sub-pixel area may be larger than red and green sub-pixel areas. In addition, since the human eye is more sensitive to green and the green emitting material is most efficient, the green sub-pixel area can be made minimal.
Of course, in other embodiments, the correspondence relationship between the light emitting colors of the first sub-pixel 122, the second sub-pixel 124 and the third sub-pixel 126 may not be limited to the above-discussed embodiments, and may be changed according to actual needs, and is not limited in detail here.

In some embodiments, the first substrate 22, the second substrate 32, and the third substrate 42 are made of a metal material.
In this way, the first mask 20, the second mask 30, and the third mask 40 may be high-precision metal masks, and may be applied to an evaporation process, in which the corresponding display panel 10 is formed by evaporating organic light-emitting materials corresponding to pixel patterns.
In some embodiments, the Mask assembly further comprises a Cover Mask (Cover Mask), a support Mask (Howling Mask), and an alignment Mask (Align Mask). The first Mask plate 20, the second Mask plate 30, and the third Mask plate 40 may be combined with a cover Mask, a support Mask, and an alignment Mask to form a Mask Frame Assembly (MFA).
Therefore, the combined mask integrated frames can be respectively placed into corresponding evaporation chambers to evaporate the organic light-emitting materials corresponding to the sub-pixels. Specifically, a pattern of one sub-pixel may be formed each time vapor deposition is performed, another sub-pixel may be formed after the formation of the pattern of one sub-pixel, and the display panel 10 according to the embodiment of the present invention may be obtained after the formation of the patterns of three sub-pixels in sequence.
