Backlight module and display device

Abstract

The invention discloses a backlight module and a display device. The backlight module comprises a light source and at least two light conversion films, wherein the light source emits at least a firstkind of light; and at least one light conversion film receives the first kind of light and converts the first kind of light to at least a second kind of light to exit, and thus, the light outgoing angle of the backlight module matches a wide-angle display requirement. The light outgoing angle of the backlight module can be enhanced, and a wide-angle effect is further achieved; and due to the at least two light conversion films, one part of light can be reflected back while the light is scattered, laser outgoing is further carried out, the light utilization rate is improved, the light brightness is enhanced, and better display effects are realized.

Description

technical field [0001] The invention relates to the technical field of liquid crystal panel display, in particular to a backlight module and a display device. Background technique [0002] Liquid Crystal Display (LCD) has the characteristics of light and thin, low power consumption, and no radiation. Computers, mobile phones, digital cameras and other electronic equipment. [0003] The inventors of the present application have found in the long-term research and development that in the prior art, when the backlight passes through polarizers, TFTs, etc., the output light has directionality, and most of the light is emitted vertically from the screen; Different positions of the LCD display will have different colors on the screen, especially when the LCD is viewed from a large angle, the original color of the screen cannot be seen, and even all white or all black can be seen, which is often said The problem of insufficient perspective. As the size of the LCD becomes larger,...
