Abstract

The invention relates to a Micro-LED display panel and a preparation method thereof. In the preparation process of the Micro-LED display panel of the present invention, the first and second heat conduction parts are respectively formed on each of the Micro-LED installation regions of the first substrate while forming the metal gate electrode and the source-drain electrode, And further forming a third through hole exposing the second heat conduction part in the first insulating layer and the planarization layer, and depositing a metal material in the third through hole to form the third heat conduction part, the above The arrangement of the first, second and third heat conducting parts can facilitate the rapid heat dissipation of the Micro-LED, effectively improve its heat dissipation performance, and further improve the service life of the Micro-LED display panel.

Description

technical field [0001] The invention relates to the technical field of semiconductors, in particular to a Micro-LED display panel and a preparation method thereof. Background technique [0002] Traditional display product technologies mainly include glass picture tube displays, liquid crystal display panels, organic light-emitting display panels, digital light processing and laser displays. However, in extreme environments such as strong light and high temperature, products based on these technologies will have low brightness, The characteristics of low efficiency and poor reliability. However, Micro-LED displays have obvious advantages in various indicators such as brightness, luminous efficiency, contrast, energy consumption, response time, viewing angle, resolution, lifespan, and weather resistance, which has aroused widespread interest from companies in the major display fields. focus on. [0003] The display principle of the Micro-LED display is to thin, miniaturize a...
