Embodiment Construction

[0023] The backlight module 20 includes a plurality of lamp tubes 21 , a reflector (not shown), a diffuser 22 , two opposite lamp tube holding devices (not shown) and a frame 25 . The frame 25 accommodates the plurality of lamp tubes 21 , the reflection sheet, the diffuser sheet 22 and the lamp tube holding device. Each light tube holding device includes a first holding piece 23 and a second holding piece 24 , the first holding piece 23 and the second holding piece 24 cooperate to fix the plurality of light tubes 21 . The light emitted by the lamp tube 21 is transmitted to the liquid crystal panel 29 through the diffuser 22 directly or after being reflected by the reflector, so that the liquid crystal panel 29 can obtain better brightness. The frame 25 includes a bottom plate 251 and four sidewalls 252 vertically adjacent to the bottom plate 251 . The inner surface of the bottom plate 251 and the side wall 252 can also be coated with a material with high reflectivity to refle...

Abstract

The invention relates to a backlight module and an LCD device adopting the backlight module. The backlight module comprises a plurality of lighting tubes and a first holding piece. Each lighting tube comprises a lighting tube body and electrodes. Two ends of the plurality of the lighting tubes are electrically held with the first holding piece. The first holding piece comprises a plurality of first receiving parts electrically holding the lighting tube and a plurality of second receiving parts matched with the first receiving parts. The second receiving parts are elastically held with the electrodes and are electrically connected with the electrodes.

Description

technical field [0001] The invention relates to a backlight module and a liquid crystal display device using the backlight module. Background technique [0002] Since the liquid crystal of the liquid crystal panel of the liquid crystal display device does not emit light, in order to achieve the display effect, it is necessary to provide the liquid crystal panel with a light source device, such as a backlight module, to realize the display function. [0003] Please refer to FIG. 1 , which is an exploded perspective view of a prior art liquid crystal display device. The liquid crystal display device 100 includes a liquid crystal module 13 , a housing 12 and a plurality of lamps 17 . [0004] Please also refer to FIG. 2 , which is an enlarged schematic diagram of part II of the liquid crystal display device 100 shown in FIG. 1 . The liquid crystal module 13 integrates a backlight module (not shown) in it, and the side 130 of the liquid crystal module 13 corresponding to the b...
