Embodiment 1

[0039] Please combine figure 1 with figure 2 , Embodiment 1 provides a pixel structure, in which there are a plurality of pixel units 100 . Each pixel unit 100 includes a first sub-pixel 110 , a second sub-pixel 120 , a third sub-pixel 130 and a fourth sub-pixel 140 . In each pixel unit 100, the second sub-pixel 120 surrounds the first sub-pixel 110 and is spaced apart from the first sub-pixel 110, and the third sub-pixel 130 surrounds the second sub-pixel 120 and is spaced apart from the second sub-pixel 120. Four sub-pixels 140 surround the third sub-pixel 130 and are spaced apart from the third sub-pixel 130 . The first sub-pixel 110 , the second sub-pixel 120 , the third sub-pixel 130 and the fourth sub-pixel 140 form a ring nested structure.

[0040] The plurality of pixel units 100 are distributed in an array, for example, in a regular multi-row, multi-column matrix.

[0041] In each pixel unit 100, among the first sub-pixel 110, the second sub-pixel 120, the third ...

Embodiment 2

[0051] like image 3 and Figure 4 As shown, the structure of the pixel unit 200 in the second embodiment is basically the same as that of the pixel unit 100 in the first embodiment, and the differences mainly include the following points.

[0052] In each pixel unit 200 of Embodiment 2, the light emission color of the first sub-pixel 210 is blue, the light emission color of the second sub-pixel 220 is green, the light emission color of the third sub-pixel 230 is red, and the light emission color of the fourth sub-pixel 240 is The emission color is white. The white fourth sub-pixel 240 can increase the brightness of the display device, thereby reducing the requirement for the luminous brightness of the first sub-pixel 210, the second sub-pixel 220, and the third sub-pixel 230, which can improve the life of the entire display device. It can be understood that, in other specific examples, the luminous color of the first sub-pixel 210 , the second sub-pixel 220 or the third sub...

Embodiment 3

[0057] like Figure 5 and Image 6 As shown, the structure and arrangement of the pixel units 300 in the pixel structure of the third embodiment are basically the same as those of the first embodiment, except for the following points.

[0058] In each pixel unit 300 of Embodiment 3, the first sub-pixel 310 is elliptical, the second sub-pixel 320 and the third sub-pixel 330 are respectively elliptical, and the entire pixel unit 300 is elliptical or rectangular. In other specific examples, the fourth sub-pixel 340 may also be in the shape of an ellipse, and the entire pixel unit 300 is in the shape of an ellipse.

[0059] The light emission color of the first sub-pixel 310 is blue, the light emission color of the second sub-pixel 320 is red, the light emission color of the third sub-pixel 330 is green, and the light emission color of the fourth sub-pixel 340 is blue. Since the color coordinates of quantum dot blue light materials are deeper, more pure blue light can be obtaine...

Abstract

The invention relates to a pixel structure, a display substrate and a display device which are favorable for realizing high-resolution display and have good stress stability. The pixel structure, thedisplay substrate and the display device comprising the display substrate are provided. On the basis of three primary colors of red, green and blue, a sub-pixel is additionally arranged, so that the color of the sub-pixel can be set as required, a high-color-gamut or high-brightness display device can be obtained, and high-resolution display can be realized by reasonably arranging the sub-pixels;a second sub-pixel of the display substrate surrounds a first sub-pixel, and a gap is formed between the second sub-pixel and the first sub-pixel; the third sub-pixel surrounds the second sub-pixel and is spaced apart from the second sub-pixel, and the fourth sub-pixel surrounds the third sub-pixel and is spaced apart from the third sub-pixel, thereby having good stress stability, and being applicable to a flexible device, especially a telescopic display device.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a pixel structure, a display substrate and a display device. Background technique [0002] Display technology has been widely used in mobile phones, computers, TVs, smart homes, vehicle displays, medical displays, outdoor advertising and other fields. Current mainstream display technologies mainly include Liquid Crystal Display (LCD), Organic Light Emitting Diode (OLED) and Inorganic Light Emitting Diode (LED). In almost all display technologies, in order to achieve a more realistic and saturated color display, it is usually necessary to arrange and combine red (R), green (G), and blue (B)—the three primary colors of display. [0003] Currently, the mainstream way of arranging the three primary colors is side by side, and the graphics used include rectangles, squares, triangular lines, rhombuses, and circles. Each pattern is a sub-pixel of one color, and each sub-pixel...
