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

The invention provides a backlight module which comprises a back panel, a backlight arranged in the back panel, a light guide plate arranged in the back panel, an optical membrane set arranged on the light guide plate, and a split-type rubber frame arranged in the back panel, wherein the split-type rubber frame comprises a plurality of corner parts arranged separately and respectively positioned on the optical membrane set; and the corner part, which is far from the optical membrane set, is provided with a supporting surface for supporting an LCD (liquid crystal display) panel. According to the backlight module, the upper surface of the split-type rubber frame serves as the supporting surface for the LCD panel, so that the supporting area of the LCD panel is increased, the supporting stability is improved, the light leakage phenomenon is prevented effectively, the brilliancy of the backlight module is ensured, and the optical grade is improved.

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...
