Embodiment Construction

[0020] see figure 2 , is a schematic structural view of the first embodiment of the liquid crystal display device of the present invention. The liquid crystal display device 2 includes a liquid crystal display panel 19 and a backlight module 20 , and the liquid crystal display panel 19 and the backlight module 20 are stacked.

[0021] The backlight module 20 includes a light source 23 , a light guide plate 22 and a frame 24 . The light guide plate 22 is a rectangular structure, which includes a light emitting surface 222 , a light incident surface 221 vertically connected to the light emitting surface 222 and a plurality of side surfaces 224 . The multiple side surfaces 224 are further provided with a colored reflective structure 220 , and the colored reflective structure 220 is directly attached to the multiple side surfaces 224 with the colored reflective material 2200 . Wherein, the colored reflective material 2200 is blue paint, and the material of the light guide plate...

Abstract

The invention comprises a light-guiding plate, a light source and an outer frame. Said light-guiding plate has a light emergence face, and light incidence face and multi side faces; said outer frame holds said light-guiding plate and the light source, and comprises multi side walls; said side walls faces the side face of the light guiding plate; between the light guiding face and its correspondedwall there is at least one colored reflection structure; the ray incident from the incident face of the light guiding plate is reflected via the colored reflection structure and is converted into theray in preset color system.

Description

technical field [0001] The invention relates to a backlight module and a liquid crystal display device using the backlight module. Background technique [0002] Liquid crystal display devices are widely used due to their characteristics of low radiation, lightness, thinness, and low power consumption. With the maturity and innovation of related technologies, there are more and more types of liquid crystal display devices. As a non-self-luminous display device, a liquid crystal display is mainly realized by controlling the passing or non-passing of light beams emitted by an external light source. Therefore, an additional surface light source, such as a backlight module, is usually required. The backlight module generally includes a light source and a light guide plate. The light guide plate converts the light beam emitted by the light source into a required plane light and guides it to the display area. [0003] Because light-emitting diodes have the characteristics of low o...
