Problems solved by technology

The split plastic frame (such as the four-corner plastic frame) has too much gap between the corner pieces 200 and insufficient support for the glass substrate, so that the entire glass is not evenly supported, resulting in excessive local stress, which has a great impact on the quality of the entire LCD module. In addition, if the gap between the corner parts is too large, there will be serious light leakage, which will affect the optical grade of the backlight module

Abstract

A backlight module comprising a back panel (2), a backlight source arranged within the back panel (2), a light-guide plate (4) arranged within the back panel (2), an optical film set (6) arranged on the light-guide plate (4), and a split-body-type plastic frame (8) arranged within the back panel (2). The split-body-type plastic frame (8) comprises several separately arranged corner pieces (82), which respectively are arranged on the optical film set (6). The corner pieces (82) are provided away from the optical film set (6) with support surfaces (822) used for supporting a liquid crystal display panel. By employing the upper surfaces of the split-body-type plastic frame (8) as the support surfaces (822) for the liquid crystal display panel, the backlight module enlarges the area for supporting the liquid crystal display panel, thus improving the support stability, effectively preventing a light-leakage phenomenon from occurring, ensuring the luminance of the backlight module, and increasing optical grade.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a backlight module. Background technique [0002] A liquid crystal display (LCD, Liquid Crystal Display) has many advantages such as a thin body, power saving, and no radiation, and has been widely used. Most of the liquid crystal display devices currently on the market are backlight liquid crystal display devices, which include a liquid crystal display panel and a backlight module. The working principle of the liquid crystal display panel is to place liquid crystal molecules between two parallel glass substrates. There are many vertical and horizontal small wires between the two glass substrates. The direction of the liquid crystal molecules is controlled by electrifying or not, and the light of the backlight module Refracted out to produce a picture. Since the liquid crystal display panel itself does not emit light, the light source provided by the backlight module is ne...
