Problems solved by technology

[0003] Generally, the light source of the backlight module is a light-emitting diode (Light-Emitting Diode, LED) or a cold-cathode fluorescent lamp (Cold Cathode Fluorescent Lamp, CCFL), which needs to emit white light through the mixing of phosphor powder, so it has weak color performance. Capability and narrow color gamut, it is difficult to provide the true color of the image
Furthermore, the light source of the backlight module consumes more power, especially for large-size liquid crystal displays.

Abstract

A backlight module (100), comprising: an optical collector (140), an optical fibre (111), an optical fibre light-emitting substrate (120), a light guide plate (130) and a light coupling element (102).The optical fibre (111) is connected between the optical collector (140) and the optical fibre light-emitting substrate (120).The light guide plate (130) is arranged at one side of the optical fibre light-emitting substrate (120).The light coupling element (102) is arranged between the optical fibre light-emitting substrate (120) and the light guide plate (130).A light diffusing recess (104) of the light coupling element (102) faces a light outlet (121) of the optical fibre light-emitting substrate (120).A display device, comprising: the backlight module (100) and a display panel (101). By means of this structure, a backlight source can be formed using external light rays.

Description

【Technical field】 [0001] The invention relates to a backlight module and a display device, in particular to a backlight module and a display device using external light. 【Background technique】 [0002] Liquid Crystal Displays (LCDs) have been widely used in various electronic products. Most of the LCDs are backlight LCDs, which are composed of a liquid crystal display panel and a backlight module. The backlight module can be divided into side-light type and direct-light type according to the incident position of the light source, so as to provide backlight to the liquid crystal display panel. [0003] Generally, the light source of the backlight module is a light-emitting diode (Light-Emitting Diode, LED) or a cold-cathode fluorescent lamp (Cold Cathode Fluorescent Lamp, CCFL), which needs to emit white light through the mixing of phosphor powder, so it has weak color performance. Capability and narrow color gamut, it is difficult to provide the true color of the image. Fu...
