Abstract

The invention discloses a light source unit, which comprises a supporting framework, a light source for emitting blue light and a quantum dot film assembly, wherein the supporting framework comprises an encapsulation slot provided with a first surface and a light emitting window, the width of the light emitting window is larger than that of the first surface; the light source for emitting blue light is encapsulated on the first surface by a encapsulating material layer; the quantum dot film assembly comprises a quantum dot film, a first protective film connected to a first side face of the quantum dot film, and a second protective film connected to a second side face of the quantum dot film; the quantum dot film assembly is connected onto the encapsulating material layer in the way that the first protective film faces the direction of the light emitting window; the width of the quantum dot film assembly is not less than that of the light emitting window; the quantum dot film assembly is configured to convert the blue light part emitted by the light source to green light and red light. The invention also discloses a backlight module of the light source unit and a liquid crystal display comprising the backlight module.

Description

technical field [0001] The present invention relates to the technical field of liquid crystal displays, in particular to a light source unit, a backlight module and a liquid crystal display. Background technique [0002] Liquid crystal display (LCD) has the advantages of thin body, low power consumption, and no radiation, and has been widely used, such as mobile phones, digital cameras, computers, TV screens, and the like. Most of the liquid crystal displays on the market are backlight liquid crystal displays, including a liquid crystal panel and a backlight module. The liquid crystal panel and the backlight module are arranged opposite to each other. With the development of society, users have higher and higher requirements for the quality of the LCD display screen. In order to improve the color saturation of the screen, the color saturation of the screen can be improved by improving the color saturation of the light bar in the backlight module. Now Some technologies use q...
