Abstract

The invention relates to a backlight module and an LCD display device. The backlight module comprises a first frame and a second frame. The first frame is used for bearing various optical elements of the backlight module, which comprises a plurality of flexible clamping elements. The second frame is provided with a plurality of jogged elements. The plurality of the flexible clamping elements and the plurality of the jogged elements are fixed clamping with each other along the vertical direction, which fixedly connects the first and the second frames and restricts the relative movement between the two frames along the horizontal and vertical direction.

Description

technical field [0001] The invention relates to a backlight module and a liquid crystal display device. Background technique [0002] At present, liquid crystal display devices 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, notebook computers, In personal digital assistants (Personal Digital Assistant, PDA), mobile phones, TVs and various office automation and audio-visual equipment. [0003] see figure 1 , is a schematic diagram of a prior art liquid crystal display device 1 . The liquid crystal display device 1 includes an upper frame 10 , a liquid crystal panel 20 and a backlight module 40 adjacent to the liquid crystal panel 20 . [0004] The upper iron frame 10 includes a first bottom plate 102 and a first side wall 104 vertically extending from the edge of the first bottom plate 102, the first ...
