Abstract

The present invention provides a micro-LED display panel and a manufacturing method thereof. The present invention utilizes an ellipsoidal raised portion and an elliptical flat surface to realize a wide viewing angle emission of red light and green light, so as to ensure the light from the blue LED Balanced color mixing while ensuring a large viewing angle for the display panel. Furthermore, the manufacturing method of the present invention can form the raised portion through simple injection molding, and the subsequent forming process of the reflective layer and the sealing layer is relatively simplified, which greatly reduces the manufacturing cost.

Description

technical field [0001] The invention relates to the field of light-emitting diode packaging and display, in particular to a micro-LED display panel 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 method for manufacturing a micro-LED display panel, which includes: [0004] providing a packaging substrate; [0005] A plurality of micro-LED chips are fixed on the packaging substrate, and the plurality of micro-LED chips include a plurality of red LEDs, a plurality of green LEDs ...
