Embodiment Construction

[0027] see Figure 4 , is a schematic side view of the first embodiment of the backlight module of the present invention. The backlight module 3 includes a diffusion plate 31 , a plurality of line light sources 32 , a reflection plate 33 , a plurality of support members 34 and a metal back plate 35 . The metal back plate 35 accommodates the diffuser plate 31 , the plurality of line light sources 32 , the reflector plate 33 , and the plurality of support members 34 . The supporting member 34 is sandwiched between the reflecting plate 33 and the diffusing plate 31 . Both ends of the linear light source 32 are held in the metal back plate 35 by lamp tube holders (not shown), and the middle part is supported by a support member 34 to prevent bending and deformation. The line light source 32 is a cold cathode fluorescent tube, and the reflector 33 is flat.

[0028] see Figure 5 ,yes Figure 4 An exploded perspective view of the supporting member 34 is shown, the supporting me...

Abstract

The invention relates to a backlight module and an LCD device. The backlight module comprises at least one lighting tube and at least one support component. Each support component comprises a fixing part and at least one holding part supporting the lighting tube, and the fixing part and the holding part are detachably independent units and can be combined into one body. The fixing part and the holding part can be separated, independently replaced and have high versatility.

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 in the liquid crystal display device does not emit light, in order to achieve the display effect, it is necessary to provide the liquid crystal display panel with a light source device, such as a backlight module, to realize the display function. Backlight modules are divided into edge-type backlight modules and direct-type backlight modules according to their structures. [0003] With the continuous expansion of the application field of liquid crystal display devices, especially the application of large-size liquid crystal display devices, such as liquid crystal televisions, the requirements for the brightness of the backlight module of the liquid crystal display device are further increased, and multiple light-emitting elements are required to improve the overall...
