Problems solved by technology
Adopting a quasi-periodic wrinkled structure can effectively improve the light extraction of the substrate and waveguide mode. Therefore, in the prior art, template imprinting is often used to prepare wrinkled or periodic concave-convex structures, and most of the existing OLED display devices are AMOLED top-emitting devices. There is a fine TFT backplane structure at the bottom, and the pixel size is small, which is difficult to realize by embossing

The invention relates to the technical field of display equipment and discloses a preparation method of an array substrate, the array substrate and a display panel. The preparation method comprises the step of successively preparing a thin film transistor device layer, a pixel flat layer, a colloid layer with a fluctuating structure and an organic light-emitting device layer with the same fluctuating structure as the colloid layer on a substrate, wherein the organic light-emitting device layer comprises an anode, an organic light-emitting layer and a cathode which are sequentially formed on the side, away from the substrate, of the colloid layer. According to the invention, the colloid layer with the fluctuating structure and the organic light-emitting device layer with the same fluctuating structure as the colloid layer are prepared; the preparation method is simple and convenient; and the light extraction efficiency can be better improved.
Description
technical field [0001] The present invention relates to the technical field of display devices, in particular to a method for preparing an array substrate, an array substrate, and a display panel. Background technique [0002] The principle of light emission of organic electroluminescent (OLED) devices is as follows: electrons and holes are respectively injected into the organic functional layer from the cathode and anode of the device, recombine in the "light-emitting layer" and convert electrical energy into light energy in the form of luminous radiation and emit it to the device outside. As a self-luminous device, OLED is very attractive in the field of outdoor display devices such as smart phones and vehicles due to its excellent electroluminescence characteristics. [0003] Generally speaking, OLED devices are limited by high refractive index components, and the light extraction efficiency is only about 20%, and about 80% of the light is confined inside the device and ...
