Mini LED backlight source module structure

Abstract

The Mini LED backlight source module structure comprises a plurality of blue light Mini LED lamp beads, a multi-layer composite film, a light conversion material layer, a diffusion particle layer and a fluorescent layer, wherein the light conversion material layer is arranged on the upper surface of the fluorescent layer, and the fluorescent layer is arranged on the upper surface of the multi-layer composite film; the diffusion particle layer is arranged on the upper surface of the light conversion material layer; the multi-layer composite film comprises a light-transmitting film layer and a splicing film material layer, the light-transmitting film layer is tightly attached to the blue light Mini LED lamp beads; the splicing film material layer is arranged between the light-transmitting film layer and the fluorescent layer; and each Mini LED lamp bead corresponds to one splicing film material layer. The effects of blue light transmission and local dodging are realized; the light conversion material layer is used for converting blue light into white light; and the diffusion particle layer is used for realizing uniformity of white light so as to form a uniform and comfortable light source.

Description

technical field [0001] The invention relates to the field of LED backlight modules, in particular to a Mini LED backlight module structure. Background technique [0002] The existing Mini LED has a small lamp bead area and large phosphor particles, which makes it difficult to realize the traditional direct glue dispensing packaging method; at the same time, because quantum dots are easily quenched by water, oxygen and high light intensity, it is also difficult to directly dispensing and encapsulating. Therefore, remote fluorescent film or fluorescent plate is generally used to convert blue light into RGB light. A typical fluorescent film is a sandwich structure, with a fluorescent conversion layer in the middle, and the upper and lower layers are support layers or protective layers. [0003] In the existing Mini LED technology, in order to achieve uniform light effect, the following methods are usually adopted: [0004] Method 1: Increase the distance between the blue light...

AI Technical Summary

Problems solved by technology

[0004] Method 1: Increase the distance between the blue light bead and the fluorescent film to achieve uniform light effect, and then emit RGB light through the fluorescent film; however, the resulting backlight is still thick;

[0005] Method 2: By increasing the density of lamp beads and increasing the amount of lamp beads used to achieve an ultra-thin effect; however, the cost will increase significantly
