Abstract

This invention relates to a sort of back-light model and liquid crystal display device which adopts this model. This back-light model consists of a light board and a glue frame which accepts this light board. This light board consists of a out-light face and a underside which corresponds to this out-light face. This glue frame consists of an underside and this underside consists of a reflecting surface which approaches the underside of this light board.

Description

technical field [0001] The invention relates to a backlight module and a liquid crystal display device using the backlight module. Background technique [0002] At present, liquid crystal displays are gradually replacing traditional cathode ray tube (Cathode Ray Tube, CRT) displays used in computers, and because liquid crystal displays are light, thin, and small, they are very suitable for use in desktop computers and laptops. Type computers, personal digital assistants (Personal Digital Assistant, PDA), portable phones, televisions and a variety of office automation and audio-visual equipment. [0003] Please refer to FIG. 1 , which is a schematic diagram of a liquid crystal display device 1 in the prior art. The liquid crystal display device 1 includes an upper frame 10 , a liquid crystal panel 20 , a backlight module 40 adjacent to the liquid crystal panel 20 and a lower frame 50 . The upper iron frame 10 is disposed above the liquid crystal panel 20 for protecting the ...
