Embodiment 1
[0025] This embodiment provides an array substrate, including a plurality of sub-pixels with a light-emitting layer, the sub-pixels are equally divided into sub-pixels of a first color, sub-pixels of a second color, and sub-pixels of a third color according to the number, and,
[0026] The first color sub-pixel is diamond-shaped;
[0027] The sub-pixels of the second color and the sub-pixels of the third color are parallelograms, and the lengths of their short sides are equal to the lengths of the sides of the sub-pixels of the first color, and the lengths of the long sides are larger than the lengths of the sides of the sub-pixels of the first color.
Embodiment 2
[0029] This embodiment provides an array substrate, which includes a plurality of sub-pixels with a light-emitting layer, and all the sub-pixels are equally divided into sub-pixels of a first color, sub-pixels of a second color, and sub-pixels of a third color.
[0030] That is to say, the array substrate of this embodiment is composed of a plurality of sub-pixels, and these sub-pixels are closely arranged so as to cover the entire display area of the array substrate without gaps. Wherein, each sub-pixel has an organic light-emitting diode, and the organic light-emitting diode has a light-emitting layer for emitting light, so the array substrate is an organic light-emitting diode array substrate. The sub-pixels in the array substrate are divided into three different colors (such as red, green, blue), and the number of sub-pixels in each color is equal.
[0031] Of course, in sub-pixels, in addition to organic light-emitting diodes (light-emitting layers), there are other str...
Embodiment 3
[0058] This embodiment provides a display device, which includes any one of the above-mentioned array substrates. The display device is in the form of an organic light-emitting diode (OLED) display device, which may specifically be: electronic paper, mobile phones, tablet computers, televisions, monitors, notebook computers, digital photo frames, navigators, and any other products with display functions or part.

Abstract
The invention provides an array substrate and a display device, and belongs to the technical field of displaying of organic light emitting diodes. The array substrate and the display device resolve the problem that sub-pixels in different colors in an existing organic light emitting diode array substrate are different in service life. The array substrate comprises a plurality of sub-pixels with luminescent layers, the sub-pixels are equally divided into first color sub-pixels, second color sub-pixels and third color sub-pixels according to numbers, the first color sub-pixels are rhombuses, the second color sub-pixels and the third color sub-pixels are parallelograms, the length of the short sides of the parallelograms is equal to the side length of the first color sub-pixels, and the length of the long sides of the parallelograms is larger than the side length of the first color sub-pixels.
Description
technical field [0001] The invention belongs to the field of organic light emitting diode display technology, and in particular relates to an array substrate and a display device. Background technique [0002] The array substrate of an organic light emitting diode (OLED) display device includes a plurality of sub-pixels, and each sub-pixel is provided with an organic light-emitting diode for emitting light of a corresponding color. The organic light-emitting diode includes a cathode, an anode, a light-emitting layer, and holes. Transport layer, hole injection layer, electron transport layer, electron injection layer, etc. Wherein, the materials of the light-emitting layers of the sub-pixels of different colors are different, so their light-emitting efficiencies and lifetimes are also different. Generally speaking, the efficiency and lifespan of the existing green light-emitting layer are the highest, while the efficiency and lifespan of the blue light-emitting layer and the...
