Abstract

The invention provides a light guide plate used for a backlight module, wherein the light guide plate comprises a main plate body and a vice plate body; the main plate body comprises a light-exiting surface, a back surface opposite to the light-exiting surface, and a first light incident surface connected to the light-exiting surface and the back surface; a plurality of evenly distributed quantum dots are inserted inside the vice plate body; the vice plate body is fixed on the first light incident surface of the main plate body and the first light incident surface is fully covered by the vice plate body; a surface of the vice plate away from the first light incident surface is used as a second light incident surface; and the second light incident surface is oppositely set to backlight source of a backlight module. The invention also discloses a backlight module and a display apparatus.

Description

Technical field [0001] The present invention relates to the technical field of liquid crystal display, in particular to a quantum tube, a backlight module, a display device and a terminal. Background technique [0002] At present, liquid crystal display devices have been widely used as display components of electronic equipment. Consumers have increasingly higher requirements for the color vividness of the equipment, which requires increasing the color gamut value of the display device; and the backlight module is a liquid crystal display device. It is an important component in the light source that the color gamut generated by the light source is bound to become increasingly demanding. [0003] One of the hotspot technologies on the market now is the use of quantum dots to improve the color gamut of the backlight. Quantum dots are quasi-zero-dimensional nanomaterials composed of a small number of atoms; their particle size is generally between 1 and 10 nm. Electrons and holes are...
