Abstract

The invention discloses an LCD (Liquid Crystal Display) device which comprises a panel module and a backlight module. The backlight module comprises a light guide plate, a framework for accommodating the light guide plate, a reflector plate, at least one light-emitting assembly and a fixing unit, wherein the light guide plate comprises a light incident surface; the framework comprises a bottom plate and side walls positioned at the periphery of the bottom plate; the reflector plate is configured between the light guide plate and the bottom plate of the framework; the at least one light-emitting assembly is opposite to the light incident surface of the light guide plate; the fixing unit consists of at lest two fixing pieces; and each fixing piece is provided with a base part and a bending part vertically extending towards the same direction from at least one end of the base part, the top face of the base part abuts against the light guide plate, the inner side of the bending part abuts against the light guide plate, the outer side of the bending part, opposite to the inner side, abuts against the side walls, and the fixing pieces are made from at least one of PET (polyethylene terephthalate) and PS (polystyrene).

Description

technical field [0001] The invention relates to a backlight module and a liquid crystal display device using the backlight module, in particular to a fixing method of a light guide plate. Background technique [0002] Since the LCD is not a self-illuminating display device, it must rely on an external light source to achieve the display effect. The general LCD almost uses a backlight module, and the backlight module mainly provides a uniform and high-brightness light source for the LCD panel. The basic principle is to use commonly used points or lines. Type light source, which converts simple and effective light into a surface light source product with high brightness and uniform brightness. In recent years, with the improvement of liquid crystal display manufacturing technology, backlight modules follow the consideration of light weight, thinner, low power consumption, high brightness and cost reduction. At the same time, the level of appearance and taste is also required. ...
