Specifically, in each pixel group 100, the number of the first sub-pixel 110, the second sub-pixel 120, and the third sub-pixel 130 is 1, and the number of the first sub-pixel 110, the second sub-pixel 120, and the third sub-pixel 130 is one of a red light emitting chip, a blue light emitting chip, or a green light emitting chip, and the light emitting colors of the first sub-pixel 110, the second sub-pixel 120, and the third sub-pixel 130 are different from each other. Of course, the light emitting color of the first sub-pixel 110, the second sub-pixel 120, or the third sub-pixel 130 may be other colors than red, blue, and green.
In each pixel group 100, the first sub-pixel 110 and the second sub-pixel 120 are arranged along a first direction, the second sub-pixel 120 and the third sub-pixel 130 are arranged along a second direction, and a central connection line of the first sub-pixel 110, the second sub-pixel 120 and the third sub-pixel 130 forms a first virtual isosceles right triangle 200. Specifically, the centers of the first sub-pixel 110, the second sub-pixel 120 and the third sub-pixel 130 are the three vertices of the first virtual isosceles right triangle 200.
In two adjacent pixel groups 100 in the same row of the array structure, a central connection line of the second sub-pixel 120 and the third sub-pixel 130 in one pixel group 100 and the first sub-pixel 110 in the other pixel group 100 forms a second virtual isosceles right triangle 210; in two adjacent pixel groups 100 in the same column of the array structure, the central connecting line of the first sub-pixel 110 and the second sub-pixel 120 in one pixel group 100 and the central connecting line of the third sub-pixel 130 in the other pixel group 100 form a third virtual isosceles right triangle 220. Naturally, the center of the second sub-pixel 120 of one of the pixel groups 100, the first sub-pixel 110 of one of the pixel groups 100 adjacent to the pixel group 100 along the row direction of the array structure, and the third sub-pixel 130 of one of the pixel groups 100 adjacent to the pixel group 100 along the column direction of the array structure form a fourth virtual isosceles right triangle 230.
Specifically, taking the pixel structure 10 shown in fig. 1 as an example: the connecting lines of the centers of the first sub-pixel 110, the second sub-pixel 120 and the third sub-pixel 130 in the pixel group 100 in the first row and the first column form a first virtual isosceles right triangle 200; the connecting lines of the centers of the second sub-pixel 120 and the third sub-pixel 130 in the pixel group 100 in the first row and the first column and the first sub-pixel 110 in the pixel group 100 in the first row and the second column form a second virtual isosceles right triangle 210; the connecting lines of the centers of the first sub-pixel 110 and the second sub-pixel 120 in the pixel group 100 in the first row and the first column and the third sub-pixel 130 in the pixel group 100 in the second row and the first column form a third virtual isosceles right triangle 220; the center connecting lines of the second sub-pixel 120 in the pixel group 100 in the first row and the first column, the first sub-pixel 110 in the pixel group 100 in the first row and the second column, and the third sub-pixel 130 in the pixel group 100 in the second row and the first column form a fourth virtual isosceles right triangle 230.
The pixel structure utilizes a "virtual pixel" technology (i.e. a technology of time-sharing multiplexing a real pixel and reproducing more virtual pixels by utilizing a persistence phenomenon of human eyes), and in the pixel structure 10, the outer center of a first virtual isosceles right triangle 200 forms a first pixel point 201; the outer center of the second virtual isosceles right triangle 210 forms a second pixel point 211; the outer center of the third virtual isosceles right triangle 220 forms a third pixel point 221; the outer center of the fourth virtual isosceles right triangle 230 forms a fourth pixel 231. Thus, after the pixel structure 10 is applied to a display panel, the resolution of the display panel can be improved on the premise that the display panel and a real pixel display panel have the same number of sub-pixels, thereby reducing the manufacturing cost of the display panel.
In one embodiment, the plurality of pixel groups 100 are arranged in an array to form an array structure, all the pixel groups 100 in the same row of the array structure are uniformly spaced, and all the pixel groups 100 in the same column of the array structure are uniformly spaced. In this way, all the pixel groups 100 in the whole pixel structure 10 are uniformly arranged, and the uniformity of light emission can be ensured.
Specifically, the first direction is the same as the row direction of the array structure, the second direction is the same as the column direction of the array structure, the first sub-pixels 110 and the second sub-pixels 120 in all the pixel groups 100 in the same row of the array structure are in the same straight line, and the third sub-pixels 130 in all the pixel groups 100 in the same row are in the same straight line; the second sub-pixel 120 and the third sub-pixel 130 of all the pixel groups 100 in the same column of the array structure are in the same straight line, and the first sub-pixels 110 of all the pixel groups 100 in the same column are in the same straight line. The connection lines of the outsides of all the first virtual isosceles right triangles 200 in the same row of the array structure are on the same straight line; the connection lines of the outer centers of all the first virtual isosceles right triangles 200 in the same column of the array structure are on the same straight line. Therefore, all the first pixel points 201 capable of being formed on the pixel structure 10 are arranged in an array manner, the first pixel points 201 on the same row on the pixel structure 10 are on the same straight line, the first pixel points 201 on the same column are on the same straight line, the first pixel points 201 are uniformly distributed, and the uniformity of light emission can be ensured.
Further, in all the first virtual isosceles right triangles 200 in the same row of the array structure, the lengths of the connecting lines of the outsides of every two adjacent first virtual isosceles right triangles 200 are the same; in all the first virtual isosceles right triangles 200 in the same column of the array structure, the lengths of the connecting lines of the outer centers of every two adjacent first virtual isosceles right triangles 200 are the same. Therefore, in all the first pixel points 201 on the same row on the pixel structure 10, the distance between two adjacent first pixel points 201 is consistent, and in all the first pixel points 201 on the same column on the pixel structure 10, the distance between two adjacent first pixel points 201 is consistent, so that the distribution uniformity of the first pixel points 201 can be ensured, and the luminous uniformity is ensured.
Further, in all the first virtual isosceles right triangles 200 in the same row of the array structure, the length of the connecting line of the outer centers of every two adjacent first virtual isosceles right triangles 200 is equal to two times of the length of the right angle side of the first virtual isosceles right triangle 200. Therefore, in two adjacent pixel groups 100 in the same row, the central connecting lines of the second sub-pixel 120 and the third sub-pixel 130 in the left pixel group 100 and the first sub-pixel 110 in the right pixel group 100 can cooperate to form a second virtual isosceles right triangle 210, and the outer center of the second virtual isosceles right triangle 210 can form a second pixel 211. In all the first virtual isosceles right triangles 200 in the same column of the array structure, the length of the connecting line of the outer centers of every two adjacent first virtual isosceles right triangles 200 is equal to twice the length of the right angle side of the first virtual isosceles right triangle. Therefore, in two adjacent pixel groups 100 in the same column, a central connecting line between the first subpixel 110 and the second subpixel 120 in the upper pixel group 100 and the central connecting line between the third subpixel 130 in the lower pixel group 100 can cooperate to form a third virtual isosceles right triangle 220, and a third pixel 221 can be formed at the outer center of the third virtual isosceles right triangle 220.
An embodiment also relates to a display panel comprising the pixel structure 10 as described above.
The pixel structure utilizes a "virtual pixel" technology (i.e. a technology of time-sharing multiplexing a real pixel and reproducing more virtual pixels by utilizing a persistence phenomenon of human eyes), and in the pixel structure 10, the outer center of a first virtual isosceles right triangle 200 forms a first pixel point 201; the outer center of the second virtual isosceles right triangle 210 forms a second pixel point 211; the outer center of the third virtual isosceles right triangle 220 forms a third pixel point 221; the outer center of the fourth virtual isosceles right triangle 230 forms a fourth pixel 231. Thus, after the pixel structure 10 is applied to a display panel, the resolution of the display panel can be improved on the premise that the display panel and a real pixel display panel have the same number of sub-pixels, thereby reducing the manufacturing cost of the display panel.
Alternatively, the display panel may be an OLED (Organic Light-Emitting Diode) display panel, a COB display panel, an LED (Light-Emitting Diode) display panel, or the like.
Specifically, the display panel is a COB display panel, and the first sub-pixel 110, the second sub-pixel 120, and the third sub-pixel 130 may be light emitting chips with a forward mounting structure or a light emitting chip with a flip-chip structure.
As shown in fig. 2, more specifically, in one pixel group 100, the first sub-pixel 110, the second sub-pixel 120, and the third sub-pixel 130 are in a positive-type structure, the first sub-pixel 110, the second sub-pixel 120, and the third sub-pixel 130 are fixed to the common electrode 300 by a die attach adhesive, the first bonding wire area 310, the second bonding wire area 320, and the third bonding wire 330 are disposed at intervals from the common electrode 300, the first sub-pixel 110 is electrically connected to the first bonding wire area 310 by a first bonding wire 340, the second sub-pixel 120 is electrically connected to the second bonding wire area 320 by a second bonding wire 350, and the third sub-pixel 130 is electrically connected to the third bonding wire area 330 by a third bonding wire 360. Therefore, the positions of the welding wire area and the position of the die bonding glue are spaced, and the welding wire quality is favorably ensured.
Based on the same inventive concept as the pixel structure 10 and the display panel, an embodiment further relates to a display device including the display panel as described above.
Alternatively, the display device may be a display screen, a mobile phone, a tablet, a palm computer, a smart watch, or other digital devices.
