Embodiment Construction

[0023] see figure 2 , is a partial schematic view of the backlight module of the present invention. The backlight module 200 includes a diffusion plate 210 , a back plate 220 , a plurality of lamp tubes 230 and a plurality of lamp tube clamping devices 240 . The lamp clamping device 240 is located between the back plate 220 and the diffusion plate 210 , and the lamp tube 230 is disposed on the lamp clamping device 240 . The lamp tube 230 is a cold cathode ray tube.

[0024] see image 3 , is a three-dimensional structure diagram of the lamp clamping device 240 . The lamp clamping device 240 includes a C-shaped clamping part 242, two supporting parts 243 formed by extending the two ends of the C-shaped clamping part 242 to the diffuser plate 210 respectively, and a locking support for the two supports. Part of the locking mechanism 244 and a fixed part 241.

[0025] The fixing part 241 is connected to the C-shaped clamping part 242 , which can be glued to the backboard 22...

Abstract

A backlight module comprises a diffusion plate, a back plate, at least one lamp tube and at least one lamp tube holding device which is positioned between the diffusion plate and the back plate and comprises a holding part for holding the lamp tube and two supporting parts which are constituted by respectively extending from the both ends of the holding part to the diffusion plate, and at least one supporting part is resisted and connected with the diffusion plate. The invention further provides a lamp tube holding device and a liquid crystal display.

Description

technical field [0001] The invention relates to a backlight module, a lamp tube clamping device and a liquid crystal display. Background technique [0002] Since the liquid crystal in the liquid crystal display panel does not emit light itself, 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. According to the structure, the backlight module can be divided into two types: edge-type backlight module and direct-type backlight module. [0003] With the continuous expansion of the application field of liquid crystal displays, especially the application of large-size liquid crystal displays, such as notebook computers and LCD TVs, the requirements for the luminance of the backlight module of liquid crystal displays are further increased, and multiple light sources are required. To improve the luminance of the entire backlight module, the trad...
