The conventional pixel arrangement structure generally includes a red sub-pixel, a blue sub-pixel and a green sub-pixel, and the three pixels are alternately arranged in a stripe shape. The traditional pixel arrangement structure has higher requirement on the display algorithm of a display panel or a display device, and is easy to generate granular sensation when the edges of the display panel at an R angle, an arc line edge and a groove opening are displayed, a displayed image has a saw-toothed phenomenon, and the display device has lower resolution and cannot finish fine display. In addition, because the service life of the blue sub-pixel in the OLED device structure is short, the arrangement structures of the red sub-pixel, the blue sub-pixel and the green sub-pixel of the traditional pixel are consistent, the phenomenon that the service life of the blue light of the OLED is short cannot be made up, and the color cast phenomenon can occur after long-time use. Therefore, the present invention provides a pixel arrangement structure, which aims to solve the above technical problems.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a repeating unit 100 according to an embodiment of the present disclosure. The pixel arrangement structure includes: the multiple repeating units 100 are arranged in an array, the repeating units 100 are in an N-sided shape, and N is more than or equal to 6; the repeating unit 100 includes at least one first subpixel 1, at least one second subpixel 2, and at least one third subpixel 3; the area ratio of the at least one first sub-pixel 1 to the at least one second sub-pixel 2 and the at least one third sub-pixel 3 in the N-sided polygon repeating unit 100 is 1:1: 2; adjacent N-sided polygon repeat units 100 are connected by edge butt, and two adjacent repeat units 100 are staggered by a preset distance in the first direction, where the preset distance is equal to one half of the total length of the repeat units 100 in the first direction.
In the pixel arrangement structure provided in the embodiment of the present application, the pixel arrangement structure includes a plurality of repeating units 100 arranged in an array, each repeating unit 100 includes at least one first sub-pixel 1, at least one second sub-pixel 2, and at least one third sub-pixel 3, and an area ratio of the at least one first sub-pixel 1 to the at least one third sub-pixel 3 and the at least one second sub-pixel 2 in the N-sided repeating unit 100 is 1:1: 2. The area ratio of the second sub-pixel 2 to the repeating unit 100 is larger than the area ratio of the first sub-pixel 1 and the third sub-pixel 3 to the repeating unit 100. That is, the area ratio of the second sub-pixel 2 is improved, the blue light service life is prolonged when the second sub-pixel 2 is a blue light sub-pixel, and the color cast risk caused by overlong use time is reduced. By arranging the adjacent N-shaped edge repeating units 100 to be in butt joint connection, and staggering the preset distance of the two adjacent repeating units 100 in the first direction, wherein the preset distance is equal to one half of the total length of the repeating units 100 in the first direction, the display jaggy of the display panel can be effectively reduced, the display graininess of the display panel is reduced, the fineness of the picture of the display panel is improved, and the pixel density (Pixels Per Inc, PPI for short) is improved.
It should be noted that the repeating unit 100 provided in the embodiment of the present application is an N-polygon, N is greater than or equal to 6, in an alternative embodiment, the N-polygon may be a regular hexagon, a non-regular hexagon, a regular octagon, a non-regular octagon, or the like, as long as the area ratio of the at least one first sub-pixel 1, the at least one second sub-pixel 2, and the at least one third sub-pixel 3 to the N-polygon repeating unit 100 is 1:1:2, and the number of the N-polygons in the embodiment of the present application is not limited thereto.
In an alternative embodiment, the N-shape provided by the embodiment of the present application is a regular hexagon, and an area ratio of the at least one first sub-pixel 1 to the at least one second sub-pixel 2 and the at least one third sub-pixel 3 in the regular hexagon repeating unit 100 is 1:1: 2. Adjacent regular hexagon repeating units 100 are connected by edge butt joint, and two adjacent repeating units 100 are staggered by a preset distance in the first direction, wherein the preset distance is equal to one half of the total length of the repeating units 100 in the first direction.
There are many ways to arrange the repeating units 100 in a staggered manner, and in some alternative embodiments, the pixel arrangement structure includes M columns and N rows of the repeating units 100. In some alternative embodiments, the repeating units 100 are arranged along the first direction to form M columns, and each column is formed by repeating the translation of N repeating units 100 along the second direction; the (i + 2) th column is formed by repeatedly translating the ith column along the first direction, and i is an integer greater than or equal to 1; the (i + 1) th row and the (i) th row are arranged in a staggered manner in the second direction, and two adjacent repeating units 100 are staggered by a preset distance in the first direction, wherein the preset distance is equal to one half of the total length of the repeating units 100 in the first direction. The arrangement mode enables the at least one first sub-pixel 1, the at least one second sub-pixel 2 and the at least one third sub-pixel 3 to be integrally and uniformly distributed in the whole pixel arrangement structure, and avoids the situation that the number of the same sub-pixels in the same direction is too large, so when the pixel arrangement structure is applied to a display panel, the display effect can be integrally improved, and the process manufacturing difficulty is reduced.
In an alternative embodiment, the repeating unit 100 is hexagonal and has a long axis extending along the second direction and a short axis extending along the first direction, and the repeating unit 100 includes a first pixel group and a second pixel group symmetrically disposed on two sides of the long axis, and the first direction is perpendicular to the second direction.
As an example, when the repeating unit 100 provided in the embodiment of the present application is a hexagon, the hexagon may be divided into two parts, that is, the hexagon has a long axis extending along the second direction and a short axis extending along the first direction. It will be appreciated that when the hexagon is a non-regular hexagon, the length of the long axis in the second direction is greater than the length of the short axis in the first direction, and when the hexagon is a regular hexagon, the length of the long axis in the second direction is equal to the length of the short axis in the first direction. That is, when the repeating unit 100 is a regular N-sided polygon, the length of the long axis in the second direction is greater than the length of the short axis in the first direction, and when the hexagon is a non-regular N-sided polygon, the length of the long axis in the second direction is equal to the length of the short axis in the first direction.
It should be noted that, the first direction and the second direction provided in the embodiments of the present application may be arranged in a variety of ways, and the first direction and the second direction may intersect at any preset angle. As an example, the included angle between the first direction and the second direction is 90 degrees, so that each of the first sub-pixel 1, the second sub-pixel 2 and the third sub-pixel 3 can be arranged horizontally and vertically along the horizontal and vertical directions, the structure is simple, and the manufacture is convenient.
In addition, two adjacent repeating units 100 in the first direction are arranged in a staggered manner, and two adjacent repeating units 100 are staggered by a preset distance in the first direction, wherein the preset distance is equal to one half of the total length of the repeating units 100 in the first direction. In two adjacent repeating units 100 in the first direction, at least one first sub-pixel 1, at least one second sub-pixel 2, or at least one third sub-pixel 3 in one repeating unit 100 and at least one first sub-pixel 1, at least one second sub-pixel 2, and at least one third sub-pixel 3 in the repeating unit 100 form one pixel unit, and on the premise of not increasing the difficulty of the manufacturing process, the display effect of the display panel is improved by adjusting the position structure of the sub-pixels.
In an alternative embodiment, the first pixel group comprises one first sub-pixel 1 and one second sub-pixel 2 with the short axis as the symmetry axis, and the second pixel group comprises one second sub-pixel 2 and one third sub-pixel 3 with the short axis as the symmetry axis.
Referring to fig. 2, fig. 2 is a schematic view of a pixel arrangement structure according to an embodiment of the present disclosure. The first pixel group includes one first sub-pixel 1 and one second sub-pixel 2 having the short axis as the symmetry axis, and the second pixel group includes one second sub-pixel 2 and one third sub-pixel 3 having the short axis as the symmetry axis. As can be seen from fig. 2, when the repeating unit 100 forms a pixel arrangement structure, the first sub-pixel 1 of the adjacent repeating unit 100 is connected to the first sub-pixel 1 of the repeating unit 100, the second sub-pixel 2 of the adjacent repeating unit 100 is connected to the second sub-pixel 2 of the repeating unit 100, and the third sub-pixel 3 of the adjacent repeating unit 100 is connected to the third sub-pixel 3 of the repeating unit 100. In this way, two first sub-pixels 1, two second sub-pixels 2, and two third sub-pixels 3 in the adjacent multiple repeating units 100 form one pixel unit, see fig. 1, where the number of the second sub-pixels 2 is twice that of the first sub-pixels 1 and the third sub-pixels 3. In this way the decay rate of the second sub-pixel 2 in the display panel is reduced. And because the same sub-pixels in two adjacent repeating units 100 are connected, evaporation can be performed by using the evaporation opening on one mask plate, the opening area of the evaporation mask plate can be effectively increased, and the manufacturing difficulty of the evaporation mask plate process is reduced.
In an alternative embodiment the first pixel group comprises a first sub-pixel 1 and a third sub-pixel 3 and the second pixel group comprises a second sub-pixel 2.
Referring to fig. 3, fig. 3 is a schematic view of a pixel arrangement structure according to an embodiment of the present disclosure. As can be seen from fig. 3, in the pixel arrangement structure provided in this embodiment, the number of the first sub-pixel 1, the second sub-pixel 2, and the third sub-pixel 3 in one repeating unit 100 is one, but the area ratio of the first sub-pixel 1, the second sub-pixel 2, and the third sub-pixel 3 in one repeating unit 100 is 1:1: 2. That is, the area of one repeating unit 100 occupied by the second sub-pixel 2 is larger than the area of one repeating unit 100 occupied by the first sub-pixel 1 and the third sub-pixel 3. And when the repeating unit 100 forms a pixel arrangement structure, the first subpixel 1 of the adjacent repeating unit 100 is connected to the first subpixel 1 of the present repeating unit 100, the second subpixel 2 of the adjacent repeating unit 100 is connected to the second subpixel 2 of the present repeating unit 100, and the third subpixel 3 of the adjacent repeating unit 100 is connected to the third subpixel 3 of the present repeating unit 100. In this way, two first sub-pixels 1, two second sub-pixels 2, and two third sub-pixels 3 in the adjacent plurality of repeating units 100 form one pixel unit. Referring to fig. 3, the number of the second sub-pixels 2 is twice that of the first sub-pixels 1 and the second sub-pixels 2. In this way the decay rate of the second sub-pixel 2 in the display panel is reduced. And because the same sub-pixels in two adjacent repeating units 100 are connected, evaporation can be performed by using the evaporation opening on one mask plate, the opening area of the evaporation mask plate can be effectively increased, and the manufacturing difficulty of the evaporation mask plate process is reduced.
In an alternative embodiment, in the N-sided polygon 100, one first sub-pixel 1 and one third sub-pixel 3 are located above the long axis extending in the second direction, and one second sub-pixel 2 is located below the long axis extending in the second direction. When the repeating unit 100 is an N-polygon, the first pixel group includes a first sub-pixel 1 and a third sub-pixel 3, and the second pixel group includes a second sub-pixel 2. At this time, in this N-sided polygonal repeating unit 100, one first sub-pixel 1 and one third sub-pixel 3 are located above the long axis extending in the second direction, and one second sub-pixel 2 is located below the long axis extending in the second direction. Further, see fig. 3. When the repeating unit 100 is a regular hexagon, the first sub-pixel 1 and the third sub-pixel 3 are located above the long axis, and the second sub-pixel 2 is located below the long axis of the regular hexagon, that is, the regular hexagon is bisected by the first sub-pixel 1, the third sub-pixel 3, and the second sub-pixel 2. Wherein the second sub-pixel 2 occupies one half of the area of the regular hexagonal repeating unit 100. The first sub-pixel 1 and the third sub-pixel 3 together occupy half of the area of the regular hexagonal repeating unit 100.
