Abstract

The present invention provides a micro-LED display structure and a manufacturing method thereof. The present invention uses the first protrusion and the second protrusion as sub-pixel points, and utilizes a light-reflecting layer placed on the outside to realize the collimation and singleness of light emission, and in addition A sub-pixel is designed between multiple protrusions to achieve sufficient light mixing. Moreover, in the manufacturing method, protrusion structures with different heights or cross-sections with different eccentricities can be formed to achieve different light output areas and optimize the light mixing effect.

Description

technical field [0001] The invention relates to the field of micro-light-emitting diode display manufacturing, in particular to a micro-LED display structure and a manufacturing method thereof. Background technique [0002] Micro-LED (mini-LED) displays have the advantages of low current, stable performance, and long life, so they are now widely studied. However, the existing micro-LED display screens have narrow light emission angles, and are prone to the problems of too bright green light and insufficient blue light at the pixels, and the problem of high cost for large-area display manufacturing. Contents of the invention [0003] Based on solving the above problems, the present invention provides a micro LED display structure, which includes: [0004] Substrate; [0005] A plurality of micro LED chips fixed on the substrate and including a plurality of red LED chips, a plurality of green LED chips and a plurality of blue LED chips; [0006] A plurality of first protr...
