Abstract

The invention discloses an LED display module and a manufacturing method thereof. The LED display module comprises a substrate provided with an LED chip; the ink color packaging layer is used for shielding light and packaging the LED chip, and the substrate and the LED chip are covered with the ink color packaging layer; and the imaging layer covers the ink color packaging layer, and a semi-transparent reflection layer is formed on one side, facing the ink color packaging layer, of the imaging layer. According to the LED display module and the manufacturing method thereof, the optical principle is fully utilized, the semi-transparent reflection layer is arranged on one side of the imaging layer, the ink color consistency of the LED display module is improved by controlling the surface roughness, the ink color height consistency of an upper screen can be achieved without selecting a piece, meanwhile, the display chromatic aberration at different angles is eliminated, and the display effect is good. And the display module with high contrast is presented.

Description

technical field [0001] The invention belongs to the technical field of display, and in particular relates to an LED display module and a manufacturing method thereof. Background technique [0002] LED indoor display application technology is booming, and there are more or less technical bottlenecks in the current use of display technologies such as projection, LCD and OLED. As a new type of small-pitch high-definition display technology, Mini & MicroLED display has attracted much attention, especially in indoor large-screen high-definition display applications, such as command centers, conference centers, security monitoring, and home large-screen TVs. [0003] There are three main technical solutions for the production of Mini&MicroLED small-pitch display modules: 1. SMD; 2. IMD (2in1, 4in1, etc.); 3. chip on board (COB). Among them, COB is even more popular because of its good display effect, high integration, simple structure and micro-pitch (currently, it is difficult f...
