Problems solved by technology

[0004] At present, the light guide plate in the backlight module is mostly made of resin materials such as polycarbonate (PC) and polymethyl methacrylate (PMMA). Total reflection occurs in the light panel, resulting in loss of light energy. Therefore, the light efficiency of the existing backlight module is low, which affects the display quality of the display device

Abstract

The invention discloses a light guide plate, a backlight module group, and a liquid crystal display device. The light guide plate comprises a light guide plate body and an optical waveguide layer disposed in the light guide plate. By adopting the technical scheme provided by the invention, the optical waveguide layer is used to modulate the stray light of the light guide plate into collimated light, which is emitted from the front side surface of the light guide plate. Compared with the prior art, the incident light loss of the light guide plate is reduced, the luminous efficiency of the backlight module group is improved, and therefore the display quality of the display device is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a light guide plate, a backlight module and a liquid crystal display device. Background technique [0002] Among the flat panel display devices, Thin Film Transistor Liquid Crystal Display (TFT-LCD) has the characteristics of small size, no radiation and relatively low manufacturing cost, and occupies a dominant position in the current flat panel display market. [0003] The backlight module is one of the key components of the liquid crystal display device. Since the liquid crystal panel itself does not emit light, the main function of the backlight module is to provide a uniform and high-brightness surface light source for the liquid crystal panel, so that the light-emitting side of the liquid crystal panel can display normally. image. In addition to being used in LCD TVs and liquid crystal displays, backlight modules can also be used in display devices that require backlights...
