Abstract

The invention provides a light guide plate, a backlight module using the light guide plate and a display device using the backlight module, wherein the light guide plate comprises a light guide plate body; the light guide plate body is provided with a light incoming surface and a light outgoing surface arranged oppositely; an optical dent for refracting and diffusing light is arranged on the light incoming surface; a refracting surface for coating a light source is formed on the inner surface of the optical dent; and the surface of the light incoming surface is also provided with a plurality of optical dots for reflecting light. Due to the light guide plate, the thickness of the backlight module and the thickness of the display device are reduced, and ultra-thin design of the display device is realized.

Description

Technical field [0001] The invention belongs to the technical field of display devices, and more specifically, relates to a light guide plate, a backlight module using the light guide plate, and a display device using the backlight module. Background technique [0002] Display devices such as monitors, LCD TVs, etc. are widely used in daily life. In order to make the light emitted by the light source in the display device more uniform, a light guide plate and a reflective plate are generally installed in the display device. The light passes through the refraction of the light guide plate and the reflection of the reflective plate. , So that the light on the light-emitting side of the light guide plate is uniformly distributed. [0003] In a display device using a direct-lit light bar, in order to achieve a better light mixing effect on the light-emitting side of the light guide plate, a longer reflection and refraction path is usually required, resulting in a thicker cavity formed ...
