Abstract

The invention discloses an array substrate and a preparation method thereof, a display panel and a display device, which relate to the technical field of display and are invented for solving the problem that the brightness of the light emitted by an organic light emitting unit in the array substrate in the related art is attenuated greatly. The array substrate, include multiple pixels, each of thepixels includes a plurality of sub-pixels, for each of the sub-pixels, the sub-pixel includes a substrate, an insulating layer, a color filter layer, a flat layer and an organic light emitting unit,At least a part of that color filtering layer is filled in the first opening; the flat layer covers the insulate layer and covers the surface of the color filter layer; and the organic light emittingunit is arranged on the flat layer. The invention can be used in an OLED display device.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate and a preparation method thereof, a display panel, and a display device. Background technique [0002] Organic Light Emitting Display (OLED) has the advantages of white light emission, low driving voltage, high luminous efficiency, short response time, high definition and contrast, nearly 180-degree viewing angle, and wide operating temperature range. It can realize flexible display and large It is recognized by the industry as a display device with the most potential for development due to its many advantages such as full-color display. [0003] Among them, contrast is an important indicator of OLED, and a higher contrast can bring users a good visual experience; the contrast of a display device is: in a dark room, the brightness under the white screen (at its brightest) is divided by the black screen (at darkest) the value obtained from the brightne...
