Abstract

A backlight module to be used on liquid crystal display consists of sell, light tube, diffusion plate and support structure includes the first element, the second element and a buffer element, the first element having a slot for supporting light tube is used to connect light tube with shell, the buffer element is set between the first element and light tube and the second element having a bar is used to support diffusing plate.

Description

technical field [0001] The invention relates to a backlight module of a liquid crystal display and its support structure, in particular to a backlight module with a support structure integrating a lamp tube support part and a diffuser plate support frame and its support structure. Background technique [0002] Liquid crystal display (LCD) is a common flat display device, which is widely used in various electronic devices, such as the use of the screen of a notebook computer or a desktop computer, or as a large screen above 30 o'clock or a wall-mounted TV . [0003] Generally speaking, the liquid crystal display must provide the light source required by the liquid crystal panel (LCD panel) through a light emitting device or a backlight module, so as to present images. For example, the types of backlight modules can usually be divided into two categories: edge light type and direct light type. Among them, the direct light type backlight module is suitable for large panels abo...
