Abstract

The invention provides an integrated package display module with high contrast and uniform color among modules. The integrated package display module comprises a driver, a PCB, an LED chip, a transparent adhesive layer and a translucent adhesive layer doped with black powder. The driver, the PCB, the LED chip and the transparent adhesive layer are arranged in turn. The translucent adhesive layer is located on one side of the LED chip away from the PCB, and covers the entire PCB.

Description

technical field [0001] The invention relates to the technical field of LED display screens, in particular to an integrated packaging display module. Background technique [0002] With the development of indoor small-pitch LED display technology, in order to achieve smaller pixel pitch and higher reliability requirements, integrated packaging indoor small-pitch LED display products have emerged as the times require. Integrated packaging technology is a product that directly encapsulates LED chips on the LED driver board, eliminating the need for SMD packaging reflow links, and adopting one-time overall packaging technology to achieve integration. It has the technical characteristics of simple structure, easy realization of high density, high reliability, and low packaging cost. Once the product came out, it has received widespread attention from the industry. However, due to the dense wiring on the surface of the high-density packaging substrate and the arrangement of LED c...
