Embodiment Construction

[0030] Please refer to FIG. 2 , which is an exploded perspective view of the first embodiment of the backlight module of the present invention. The backlight module 200 includes a base body 20 and one or more pairs of holders 30. The base body 20 is a box-like frame with a light-reflecting base plate 21 and walls 22 protruding from the base plate 21. The body 30 is fixed in the frame, and it has a groove body 32. The groove body 32 is a groove with different sizes in the axial space. A plurality of linear light sources 40 are accommodated in the plurality of groove bodies 32. The two ends of the groove body are The tank body 32 is held elastically. The linear light source 40 includes a light source body 41 and an electrode 42 protruding from the end of the light source body 41 . The diameter of the electrode 42 is smaller than that of the light source body 41 , and is electrically connected to a power source (not shown).

Description

【Technical field】 [0001] The invention relates to a backlight module and a liquid crystal display device. 【Background technique】 [0002] A liquid crystal display device is a thin, light, power-saving, and highly digital display device, which is widely used, and one of the important applications is large-size displays, such as LCD TVs. [0003] Large-size liquid crystal display devices require more light sources in the backlight module, such as cold cathode fluorescent tubes. Therefore, modularization of various components in the liquid crystal display device and rapid assembly of light sources are conducive to improving the production efficiency of the liquid crystal display device. [0004] Please refer to FIG. 1 , which is a liquid crystal display device disclosed in US Patent No. 6,330,150 issued on December 11, 2001. The liquid crystal display device 100 includes a liquid crystal panel 13 , a casing 12 and a plurality of lamp tubes 17 . The liquid crystal panel 13 int...
