Abstract

The invention relates to a backlight module comprising a frame, a light guide plate, a light source and an optical film assembly. The light guide plate has a light entering surface and a light exiting surface, and is arranged in the frame. The light source is positioned in the frame and faces the light entering surface. Light emitted from the light source is non-white light. The optical film assembly is disposed on the light exiting surface and includes a first color conversion layer and a second color conversion layer. At least a part of the light emitted from the light source passe through the second color conversion layer and not the first color conversion layer. The first color conversion layer and the second color conversion layer are used for converting the light emitted from the light source from the non-white light into white light. The backlight module of the invention helps to solve problems that a conventional backlight module is uneven in brightness and chroma.

Description

technical field [0001] The invention relates to an electronic device, especially a display device with a backlight module. Background technique [0002] The rapid progress of the multimedia society is mostly benefited from the rapid development of semiconductor devices or display devices. As far as display components are concerned, cathode display tubes (or called image tubes, Cathode Ray Tube, CRT) have been monopolizing the display market due to their excellent display quality and economy. However, CRT-type displays have the problems of being too large and consuming too much energy. For the requirements of high image quality, low power consumption, thin mass production, low-voltage drive, and small size, CRT-type displays are obviously unable to achieve this. Require. In view of this, liquid crystal display (Liquid Crystal Display, referred to as LCD) will have great advantages, and LCD has been widely used in medium and small portable TVs, video phones, camcorders, note...
