Abstract

The invention relates to a light source module applied to a mini LED / micro LED and a manufacturing method thereof. The light source module comprises a back plate supporting piece, a flexible circuit board attached to the interior of the back plate supporting piece and a plurality of LED chips installed on the flexible circuit board. Diffusion particles are mixed in the packaging adhesive layer covering the LED chip on the whole surface, the particle size ranges from 10 micrometers to 20 micrometers, and a reflection pattern coating is arranged on the inner surface of the flexible circuit board. The reflection pattern coating is configured at a portion including the flexible circuit board in the mounting gap. The light source module has the advantage that the light source module is thinned,and when the mini LED is applied, the dark space contrast ratio between light-emitting points of the LED light source can be reduced before the light domain is expanded, or the pixel primary color light premixing effect can be achieved when the micro LED is applied.

Description

technical field [0001] The present invention relates to the technical field of semiconductor light source devices, in particular to a light source module applied to miniLED / microLED and a manufacturing method thereof, which can be applied to a miniLED backlight module or a microLED display panel device. Background technique [0002] Mini LED backlight modules and micro LED display panel devices are the development direction of the semiconductor display industry, aiming to provide users with a better experience. At present, in the common main structure of Mini LED / Micro LED, after welding the flip-chip LED chip on the circuit board, it is encapsulated by silica gel, and a single packaged LED chip is installed on the module board to form a light board, and the FPCA light board is placed. A functional structural film to achieve a satisfactory luminous effect in the market. The main functional films in Mini LED backlight modules in the prior art include: 1. Diffusion film, whos...
