Abstract

The disclosure provides an array substrate and a preparation method thereof, which belong to the field of display technology. The array substrate includes a base substrate, a driving circuit layer, an organic light-emitting layer and a packaging layer, wherein the base substrate is provided with a light-transmitting area and a non-light-transmitting area surrounding the light-transmitting area; the driving circuit layer is arranged on the substrate On one side of the base substrate, the orthographic projection of the driving circuit layer on the base substrate is located in the non-light-transmitting region; the organic light-emitting layer is arranged on the side of the driving circuit layer away from the base substrate; The organic light-emitting layer is provided with a plurality of light-emitting units, and the orthographic projection of any one of the light-emitting units on the base substrate is located in the non-light-transmitting region; the encapsulation layer is arranged on the organic light-emitting layer away from the substrate one side of the base substrate, and cover the non-light-transmitting area and the light-transmitting area. The array substrate can improve the light transmittance in the light transmittance area.

Description

technical field [0001] The present disclosure relates to the field of display technology, in particular to an array substrate and a preparation method thereof. Background technique [0002] With the development of display technology, people have higher and higher requirements for the light transmittance of transparent display screens or partially transparent display screens, so as to meet the needs of such as under-screen light probes and under-screen cameras. [0003] In the prior art, although a part of the blank area can be reserved as a light channel by concentrating sub-pixels, a large loss will be generated when the light passes through the blank area, which reduces the light transmittance of the display screen and restricts the The application and effect of light probe, off-screen camera and other technologies. [0004] The above information disclosed in this Background section is only for enhancement of understanding of the background of the disclosure and therefore...
