Abstract

The invention provides an array substrate, a preparation method thereof, and a display panel. The array substrate includes a base and a driving circuit arranged on the base, and also includes a light-emitting element and an auxiliary transfer structure arranged above the driving circuit. Both the light-emitting element and the auxiliary transfer structure are located in the pixel area. The electrical connection is used to provide the driving signal sent by the driving circuit to the light-emitting element, so as to drive the light-emitting element to emit light. The array substrate is provided with an auxiliary transfer structure, which can assist in transferring the prepared light-emitting elements to the substrate during the preparation process of the array substrate, so as to complete the preparation of the array substrate. Compared with the preparation of the existing transistor liquid crystal display array substrate, The preparation process of the array substrate is greatly simplified, the production cycle of the array substrate is shortened, and the mass production efficiency of the array substrate is improved.

Description

technical field [0001] The invention belongs to the technical field of display, and in particular relates to an array substrate, a preparation method thereof, and a display panel. Background technique [0002] At present, thin-film transistor liquid crystal displays (TFT-LCDs) are widely used, but thin-film transistor liquid crystal displays (TFT-LCDs) require the preparation of array substrates and color filter substrates and the process of combining the two. The manufacturing process is complicated and the manufacturing cycle is long. At the same time, during the production process, the quality of the film layer in the array substrate and the color filter substrate is difficult to guarantee, and frequent testing and repairs are required, which makes the mass production efficiency of the TFT liquid crystal display low. SUMMARY OF THE INVENTION [0003] Aiming at the problems in the prior art, the present invention provides an array substrate, a preparation method thereof,...
