Abstract

The invention discloses a light guiding plate. The light guiding plate comprises a bottom surface and a light exiting surface, wherein the light exiting surface is opposite to the bottom surface and is recessed to form a groove (2211); the groove (2211) is filled with a plurality of luminous quantum dots (231); and a closing diaphragm (240) covers the light exiting surface so that the luminous quantum dots (231) are sealed in the groove (2211). The invention also discloses a backlight module with the light guiding plate and a liquid crystal display with the backlight module. The groove is formed in the light exiting surface of the light guiding plate and is filled with the luminous quantum dots (231), the color gamut of display backlight can be increased by the luminous quantum dots (231), the luminous quantum dots (231) surround side walls of the periphery of the groove, so that the light guiding plate can be thinned to the maximum extent, and a narrow frame design of the backlight module is easy to implement.

Description

technical field [0001] The invention belongs to the technical field of liquid crystal display, and in particular relates to a light guide plate, a backlight module and a liquid crystal display. Background technique [0002] Currently, liquid crystal displays, as display components of electronic equipment, have been widely used in various electronic products. As consumers have higher and higher requirements on the vividness of colors displayed by electronic devices, it is necessary to increase the color gamut of liquid crystal displays as display components in electronic devices. Generally, an existing liquid crystal display includes a liquid crystal panel disposed opposite to each other and a backlight module for providing display backlight to the liquid crystal panel. As one of the most important components of a liquid crystal display, the backlight module provides the color gamut of the display backlight to the liquid crystal panel directly determines the color gamut of t...
