Detailed Description
In order to explain technical contents, achieved objects, and effects of the present invention in detail, the following description is made with reference to the accompanying drawings in combination with the embodiments.
Referring to fig. 1 to 3, an OLED panel pixel arrangement includes a pixel 1 composed of a first sub-pixel, a second sub-pixel, and a third sub-pixel, where the pixel 1 is rectangular;
the first sub-pixel, the second sub-pixel and the third sub-pixel respectively correspond to a first triangle 2, a second triangle 3 and a third triangle 4 which are formed by connecting any one point of one side of the rectangle with two end points of the opposite side.
From the above description, the beneficial effects of the present invention are: the utility model provides an OLED panel pixel arrangement structure, by triangle-shaped's red pixel, blue pixel and green pixel and constitute individual rectangle pixel, change the same arrangement structure of current area, become the triangle-shaped of different area proportions and arrange the problem that produces colour difference and colour cast when slowing down pixel 1 and arranging the application.
Further, the first sub-pixel, the second sub-pixel and the third sub-pixel of the pixel 1 correspond to a first triangle 2, a second triangle 3 and a third triangle 4 formed by connecting a middle point of one side of the rectangle with two end points of an opposite side, respectively.
As can be seen from the above description, the midpoint of one point of the rectangle is connected to the two endpoints of the opposite side, and the area ratio of the sub-pixel in the pixel 1 is divided into 1: 1: 2, filling a certain sub-pixel with lower luminous efficiency in the triangle with area ratio of 2, so that the certain sub-pixel with lower luminous efficiency has larger luminous area, and the problem of color difference and color cast generated on the whole effect of the pixel 1 due to poor luminous efficiency of the certain pixel is alleviated.
Further, the blue pixel corresponds to a second triangle 3 with the opposite side as the base, which is formed by any one point of one side of the rectangle and two end points of the opposite side.
From the above description, when the light emitting efficiency of the blue pixel is relatively low, the area ratio of the blue pixel in the pixel 1 is increased to alleviate the problem of color difference and color shift in the overall effect of the pixel 1 caused by the poor light emitting efficiency of the blue pixel.
Further, adjacent ones of the pixels 1 are axisymmetric with respect to the adjacent sides.
As can be seen from the above description, the adjacent pixels 1 are arranged in an axisymmetric manner with respect to the adjacent sides, and the same sub-pixels in the adjacent pixels 1 can be modulated at the same directional position, which is beneficial to increasing the number of pixels per inch of diagonal of the OLED screen.
Furthermore, the upper, lower, left and right adjacent pixels 1 form a pixel arrangement of a field-shaped full-page OLED panel;
and the pixels of the full-page OLED panel are arranged to form the pixel arrangement of the OLED panel.
As can be seen from the above description, in the process of generating the OLED panel, every 4 full-page pixel arrangements of the pixels 1 forming the "field" shape are spread and arranged on the basis of the full-page pixel arrangements, so that the area of the pattern formed by splicing the same sub-pixels of the adjacent pixels 1 on the OLED panel is the same as that of the single pixel 1, and the opening design during evaporation only needs to be made corresponding to the shape of the spliced pattern. When screen resolution is improved, the area of the opening is not reduced, so that the difficulty of the manufacturing process is reduced, namely, when the screen resolution is improved, the area of the opening does not need to be changed, and therefore the purchase and die sinking cost of the mask strips provided with the openings is reduced.
Further, the rectangle is square.
As can be seen from the above description, the single pixel 1 is square, that is, the pixel ratio of the pixel 1 is 1: 1. to ensure good screen display, the ratio of the length to the width of a single pixel 1 should be close to 1: within 1, the difference should not be too large.
Referring to fig. 1, a first embodiment of the present invention is:
an OLED panel pixel arrangement comprises a pixel 1 consisting of a first sub-pixel, a second sub-pixel and a third sub-pixel, wherein the pixel 1 is rectangular, and the first sub-pixel, the second sub-pixel and the third sub-pixel respectively correspond to a first triangle 2, a second triangle 3 and a third triangle 4 which are formed by connecting any one point of one side of the rectangle with two end points of the opposite side. In the present embodiment, the dot positions on any side of the rectangle determine the area sizes of the first triangle 2 and the third triangle 4 in the rectangle, that is, the area ratios of the first sub-pixel, the second sub-pixel and the third sub-pixel in the pixel 1 are changed.
Referring to fig. 1, the second embodiment of the present invention is:
in the OLED panel pixel arrangement, in the first embodiment, the blue pixel corresponds to a second triangle 3 with an opposite side as the bottom, which is formed by any one point of one side and two end points of the opposite side of the rectangle. In the embodiment, taking the low light emitting efficiency of the blue pixel as an example, the light emitting area of the blue pixel is set as the second triangle 3 with the largest area in the triangles, so as to improve the color display effect of the whole pixel 1 and alleviate the problems of color shift and color difference caused by the low light emitting efficiency of the blue pixel. In other equivalent embodiments, such as a red pixel or a green pixel having low luminous efficiency, the luminous area of the pixel 1 is increased.
Referring to fig. 1 to fig. 3, a third embodiment of the present invention is:
based on the first embodiment, as shown in fig. 1, the first sub-pixel, the second sub-pixel, and the third sub-pixel of the pixel 1 correspond to a first triangle 2, a second triangle 3, and a third triangle 4 formed by connecting a middle point of one side of a rectangle with two end points of an opposite side, respectively. In the embodiment, the areas of the first triangle 2 and the third triangle 4 are half of the area of the second triangle 3, and the second triangle 3 can be formed by two first triangles 2, two third triangles 4 or one first triangle 2 and one third triangle 4.
On the basis of the above area relationship, as shown in fig. 2, the adjacent pixels 1 are axisymmetric with respect to the adjacent sides. Furthermore, the upper, lower, left and right adjacent pixels 1 form a pixel arrangement of a field-shaped full-page OLED panel, and as shown in fig. 3, a plurality of full-page OLED panel pixels form a pixel arrangement of an OLED panel. In the present embodiment, the blue element is used as the sub-pixel in the second triangle 3, and the sub-pixels in the first triangle 2 and the third triangle 4 are green pixels or red pixels because they are arranged in the above symmetrical manner. The sub-pixels of the adjacent pixel 1, i.e., two blue pixels, four red pixels, or four green pixels, form the same diamond shape, and the area of the diamond shape is the same as that of the single pixel 1.
When an actual OLED screen is manufactured, the precision of the metal mask plate is extremely critical, under the same screen size, the higher the screen resolution is, the more the number of the pixels 1 is, the smaller the area of each pixel 1 is, the size of the corresponding opening of the metal mask plate also needs to be reduced, the alignment difficulty is increased, and the precision of the metal mask plate is influenced. In the mesh stretching technology, when the size of the openings of the metal mask strips is small and the number of the openings is large, the phenomena of hole deformation, insufficient precision, wrinkles on two sides and the like are easily generated under the action of tension on the two sides. Obviously, in the pixel arrangement of the OLED panel in this embodiment, when the number of the pixels 1 is increased, the openings are designed to be rhombuses having the same area as that of the single pixel 1, which does not have the above-mentioned problems of affecting the accuracy of the metal mask plate and increasing the difficulty in the screen-opening technology due to the reduction of the area of the openings.
From the above description, the beneficial effects of the present invention are: the utility model provides an OLED panel pixel arrangement structure, by triangle-shaped red pixel, blue pixel and green pixel and constitute individual rectangle pixel, change the same arrangement structure of current area, become the triangle-shaped of different area proportions and arrange, slow down the pixel and arrange the problem that produces colour difference and colour cast when using. When the luminous efficiency of one of the sub-pixels is weak, the luminous area is increased, and the luminous effect is improved. Specifically, the area ratio of the sub-pixels is adjusted to 1: 1: 2, and arranged in such a way that adjacent pixels are axisymmetric with respect to adjacent sides to constitute an OLED panel pixel arrangement. Therefore, under the same screen size, the number of pixels is increased, the screen resolution is improved, and meanwhile, the size of the holes on the mask strips in the OLED screen manufacturing process is not reduced, so that the difficulty of the screen-stretching technology is reduced, and the purchase quantity and the die sinking cost of the mask strips are reduced.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all equivalent modifications made by the contents of the present specification and the drawings, or applied to the related technical fields directly or indirectly, are included in the scope of the present invention.
