Assembled Mini LED quantum dot microcrystalline light-emitting panel and preparation method thereof

Abstract

The invention discloses an assembled Mini LED quantum dot microcrystalline light-emitting panel, which comprises circuit substrates, Mini LED chips are welded on the circuit substrates, and a protective colloid material and a diffusion material are covered on the circuit substrates on which the Mini LED chips are welded; a plurality of connecting terminals are arranged on the circuit substrates, and the plurality of circuit substrates are connected in an assembled manner through the connecting terminals; quantum dot microcrystal layers are attached to the circuit substrates, and the quantum dot microcrystal layers are a plastic film or a colloid layer for curing quantum dot microcrystals. The assembled Mini LED quantum dot microcrystalline light-emitting panel has the advantages that the thickness is smaller than that of a traditional mode and is more than one fifth of that of a direct type, the light-emitting panel is very thin, brightness loss is small, the same brightness is achieved, power consumption is small, and energy is saved by more than 30%; the brightness is uniform, light and shade cannot be seen, and a perfect light-emitting surface is formed; subsequent television assembly is greatly simplified, the yield of products is improved, and the assembly cost is reduced; and a functional film is not used, so that the diffusion material cost is greatly reduced.

Description

technical field [0001] The invention relates to a quantum dot light emitting panel, in particular to an assembled MiniLED quantum dot microcrystalline light emitting panel, and also relates to a preparation method of the assembled MiniLED quantum dot microcrystalline light emitting panel. Background technique [0002] The liquid crystal display of the backlight module has higher color saturation than the prior art, especially its color saturation is more than 90% relative to NTSC standard. [0003] However, the current process of making quantum dots on the membrane is not yet mature, and the yield of large-area quantum dot membranes is not high, or due to equipment limitations, it is impossible to prepare large-area quantum dot membranes at all. Therefore, if a large-sized backlight module needs to use a quantum dot film, a special structural design is required. [0004] In addition, the disadvantages of the traditional backlight method: 1. Whether it is a direct type or a ...

Problems solved by technology

[0004] In addition, the disadvantages of the traditional backlight method: 1. Whether it is a direct type or a side type, the brightness loss is serious, the efficiency is low, and the power consumption is large; 2. The diffusion is uneven, which may easily cause uneven brightness of the display screen; 3. Assembly process Many, the yield rate is not high, time-consuming; 4. To achieve the required effect, multi-layer functional films are required, and the cost of materials is high
