The conventional pixel arrangement structure generally includes red sub-pixels, blue sub-pixels and green sub-pixels, and the three pixels are alternately arranged in a stripe shape. The traditional pixel arrangement structure has higher requirements on a display algorithm of a display panel or a display device, granular feel is easy to appear when the display panel displays at the edges of an R angle, an arc line edge and a groove opening, the displayed image has a jaggy phenomenon, the resolution ratio is lower, and fine display cannot be completed. In addition, as the service life of the blue sub-pixel in the OLED device structure is shorter, the arrangement structure of the red sub-pixel, the blue sub-pixel and the green sub-pixel of the traditional pixel is consistent, the phenomenon that the service life of the blue light of the OLED is short can not be compensated, and the color cast phenomenon can be caused when the OLED device is used for a long time. Therefore, an embodiment of the present application provides a pixel arrangement structure, which aims to solve the above technical problems.
Referring to fig. 1 together, fig. 1 is a schematic structural diagram of a repeating unit 100 according to an embodiment of the application. The pixel arrangement structure includes: a plurality of repeating units 100 arranged in an array, wherein the repeating units 100 are in an N-sided shape, and N is more than or equal to 6; the repeating unit 100 comprises at least one first sub-pixel 1, at least one second sub-pixel 2 and at least one third sub-pixel 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 to the N-sided polygon repetitive unit 100 is 1:2:1; adjacent N-sided repeating units 100 are connected by edge butt joints, and adjacent two repeating units 100 are staggered in the first direction by a preset distance equal to one half of the total length of the repeating units 100 in the first direction.
The pixel arrangement structure provided by the embodiment of the application comprises a plurality of repeating units 100 arranged in an array, wherein each repeating unit 100 comprises at least one first sub-pixel 1, at least one second sub-pixel 2 and at least one third sub-pixel 3, and the area ratio of the at least one first sub-pixel 1 to the at least one third sub-pixel 3 to the at least one second sub-pixel 2 occupying the N-sided repeating unit 100 is 1:2:1. The area ratio of the repeating unit 100 occupied by the second sub-pixel 2 is larger than the area ratio of the repeating unit 100 occupied by the first sub-pixel 1 and the third sub-pixel 3. Namely, the area ratio of the second sub-pixel 2 is improved, the service life of blue light is prolonged when the second sub-pixel 2 is a blue sub-pixel, and the color shift risk caused by overlong service time is reduced. Through setting up adjacent N polygon repeating unit 100 and pass through the edge butt joint and connect, and adjacent two repeating unit 100 stagger the preset distance in first direction, preset distance equals the half of repeating unit 100 total length in first direction, can effectively reduce display panel and show the sawtooth sense, reduce display panel and show the graininess, improve display panel picture's fine and smooth nature, promoted pixel density (Pixels Per Inch, abbreviated as PPI).
It should be noted that, in the embodiment of the present application, the repeating unit 100 is in an N-sided polygon, where N is greater than or equal to 6, and in an alternative embodiment, the N-sided 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 at least one first sub-pixel 1 to at least one second sub-pixel 2 to at least one third sub-pixel 3 in the N-sided polygon repeating unit 100 is 1:2:1, which is not limited to the number of N-sided polygons in the embodiment of the present application.
In an alternative embodiment, the N-sided polygon provided in the embodiment of the present application is a regular hexagon, and the area ratio of at least one first subpixel 1 to at least one second subpixel 2 to at least one third subpixel 3 occupies the regular hexagon repeating unit 100 is 1:2:1. Adjacent regular hexagonal repeating units 100 are connected by edge butt joint, and adjacent two repeating units 100 are staggered in the first direction by a preset distance equal to one half of the total length of the repeating units 100 in the first direction.
There are various ways in which the repeating units 100 may be arranged in offset fashion, and in some alternative embodiments the pixel arrangement includes M columns, N rows of repeating units 100. In some alternative embodiments, repeating units 100 are arranged in a first direction to form M columns, each column being formed by translating repeating N repeating units 100 in a second direction; the (i+2) th column is formed by repeatedly translating the (i) th column along the first direction, wherein 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 the 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 ensures that at least one first sub-pixel 1, at least one second sub-pixel 2 and at least one third sub-pixel 3 are uniformly distributed in the whole pixel arrangement structure, and avoids the condition that the number of the same sub-pixel is excessive in the same direction, so that 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 has a hexagonal shape and has a long axis extending along a second direction and a short axis extending along a first direction, and the repeating unit 100 includes a first pixel group and a second pixel group disposed symmetrically 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, a long axis extending in the second direction and a short axis extending in the first direction along the hexagon. It will be appreciated that when the hexagon is a non-regular hexagon, the length of the major axis in the second direction is greater than the length of the minor axis in the first direction, and when the hexagon is a regular hexagon, the length of the major axis in the second direction is equal to the length of the minor 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, in the embodiment of the present application, there are various setting manners of the first direction and the second direction, and the first direction and the second direction may be intersected and set 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 horizontally and vertically arranged along the horizontal and vertical directions, and the structure is simple and the manufacturing is convenient.
In addition, two adjacent repeating units 100 are arranged in a staggered manner in the first direction, and the 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 the 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 a 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 a first sub-pixel 1 and a second sub-pixel 2 with the minor axis as the symmetry axis, and the second pixel group comprises a second sub-pixel 2 and a third sub-pixel 3 with the minor axis as the symmetry axis.
Referring to fig. 2, fig. 2 is a schematic diagram of a pixel arrangement structure according to an embodiment of the application. The first pixel group comprises a first sub-pixel 1 and a second sub-pixel 2 with the minor axis as the symmetry axis, and the second pixel group comprises a second sub-pixel 2 and a third sub-pixel 3 with the minor 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 present repeating unit 100, the second sub-pixel 2 of the adjacent repeating unit 100 is connected to the second sub-pixel 2 of the present 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 present repeating unit 100. As such, 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, see fig. 1, wherein the number of 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 the two adjacent repeating units 100 are connected, vapor deposition can be performed by utilizing the vapor deposition opening on one mask plate, so that the opening area of the vapor deposition mask plate can be effectively increased, and the manufacturing difficulty of the vapor deposition 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 diagram of a pixel arrangement structure according to an embodiment of the application. 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 ratio of the first sub-pixel 1 to the second sub-pixel 2 to the third sub-pixel 3 in the area of one repeating unit 100 is 1:2:1. That is, the second sub-pixel 2 occupies a larger area of one repeating unit 100 than the first sub-pixel 1 and the third sub-pixel 3 occupy a larger area of one repeating unit 100. 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 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 the two adjacent repeating units 100 are connected, vapor deposition can be performed by utilizing the vapor deposition opening on one mask plate, so that the opening area of the vapor deposition mask plate can be effectively increased, and the manufacturing difficulty of the vapor deposition mask plate process is reduced.
In an alternative embodiment, in the N-sided polygon repeating unit 100, one first subpixel 1 and one third subpixel 3 are located above the long axis extending in the second direction, and one second subpixel 2 is located below the long axis extending in the second direction. When the repeating unit 100 is of an N-sided shape, the first pixel group includes one first subpixel 1 and one third subpixel 3, and the second pixel group includes one second subpixel 2. At this time, in this N-polygonal repeating unit 100, one first subpixel 1 and one third subpixel 3 are located above the long axis extending in the second direction, and one second subpixel 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 subpixel 1 and the third subpixel 3 together occupy one half of the area of the regular hexagonal repeating unit 100. Thus, when the plurality of regular hexagon repeating units 100 are connected, the plurality of second sub-pixels 2 can share the vapor deposition opening on one mask plate for vapor deposition, so that the opening area of the vapor deposition mask plate can be effectively increased, and the manufacturing difficulty of the vapor deposition mask plate process is reduced.
In an alternative embodiment, in the N-sided polygon repeating unit 100, the first subpixel 1 has a parallelogram shape, the third subpixel 3 has a triangle shape, and the second subpixel 2 has a trapezoid shape.
