Backlight module

Abstract

The invention provides a backlight module. The backlight module comprises a substrate, a plurality of light-emitting chips and a color conversion composite film, wherein the light-emitting chips are arranged on the substrate in an array mode, and the color conversion composite film covers the surfaces of the light-emitting chips. The color conversion composite film comprises a transparent protective material and a plurality of color conversion films which are coated by the transparent protective material and are dispersedly arranged, each light-emitting chip in the plurality of light-emittingchips is correspondingly provided with a color conversion film, and each color conversion film is arranged on the top surface of the corresponding light-emitting chip. According to the backlight module, the color conversion film and the light-emitting chip are correspondingly arranged, the light-emitting consistency is good, the manufacturing cost is low, and good practicability is achieved.

Description

technical field [0001] The invention relates to the field of LEDs, in particular to a backlight module. Background technique [0002] In the existing backlight module, the blue light of the light-emitting chip is usually diffused through a diffusion plate, and then the blue light is converted into white light through a quantum dot film to obtain the required white backlight. [0003] figure 1 It shows a schematic structural diagram of an existing backlight module. In the existing backlight module, several light-emitting chips 102 are arrayed on a substrate 101, and the substrate 101 is covered with a layer of transparent adhesive layer 104 with a flat top surface. The adhesive layer 104 covers the plurality of light-emitting chips 102; the diffuser plate 105 is attached and arranged on the top of the transparent adhesive layer 104, and is used to disperse the blue light emitted by the light-emitting chips 102 to form a surface light source with a relatively uniform light in...

AI Technical Summary

Problems solved by technology

[0004] Due to the existence of the transparent adhesive layer, the thickness of the existing backlight module is relatively thick, and the application range is relatively limited

[0005] In addition, the existing quantum dot film 100 is made up of quantum dots 111 coated based on the transparent protective material 112; Can cause partial quantum dot 111 to fail, the scope of application of quantum dot film 100 is narrower;
