Abstract

The present invention relates to a backlight module. It includes a frame, a reflecting plate, at least a light source, a transparent caved type plate, a scattering plate and several optical blooming films, in which the reflecting plate is placed on the bottom portion of frame, and the light source is placed in the frame, and positioned over the reflecting plate. Besides, the transparent caved type plate is placed on the frame and is positioned over the light source, and the scattering plate is placed on the transparent caved plate, in which a gap can be formed between the scattering plate and transparent caved type plate. Besides, several optical blooming films are placed on the scattering plate. Because the transparent caved type plate is placed in the backlight module, so that it can solve the problem of that heat energy of light source can be transferred into the liquid crystral display panel.

Description

technical field [0001] The invention relates to a backlight module in a display, in particular to a backlight module (Back Light Module) capable of preventing heat energy from a light source from being transmitted to an upper liquid crystal panel. Background technique [0002] In order to adapt to the modern life style, the volume of video or image devices is becoming thinner and thinner day by day. Although the traditional cathode ray display (CRT) still has its advantages, due to the structure of the internal electronic cavity, the display is bulky and takes up space, and there are still problems such as radiation damage to the eyes when displaying. Therefore, flat panel displays (Flat Panel Displays), such as liquid crystal displays (LCDs), organic light-emitting displays (OLEDs), or plasma displays (Plasma Display Panels, PDPs), which are developed in conjunction with optoelectronic technology and semiconductor manufacturing technology, have gradually become a display T...
