Light guide plate and backlight module set

Abstract

The invention discloses a light guide plate. The light guide plate includes a main body and a fluorescent layer; the main body includes a light outgoing surface, a bottom surface, a first side surface and a second side surface, wherein the first side surface and the second side surface are arranged oppositely and are connected between the light outgoing surface and the bottom surface; the fluorescent layer is located on the light outgoing surface; the fluorescent layer includes a plurality of micro structures which are arranged side by side; quantum dots are packaged in the micro structures; the micro structure comprises a micro structure light incoming surface; the micro structure light incoming surface is arranged on the light outgoing surface; and the micro structure is thick at the middle and is thin are two ends along a direction vertical to the micro structure light incoming surface. The invention also provides a backlight module set. With the light guide plate and the backlight module set of the invention adopted, color uniformity can be improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a light guide plate and a backlight module. Background technique [0002] At present, the color gamut level of mainstream liquid crystal display devices (including flat panel display devices) on the market is only about 72%, or even lower. In order to improve the color gamut, quantum dot (QuantumDot, QD) backlight technology emerges as the times require, which can increase the color gamut of display products to 100%, greatly enriching the performance capabilities of display products. However, for the backlight module using quantum dots, due to the uneven distribution of quantum dots on the film or the difference in the excitation efficiency of quantum dots at the edge and center of the film, the internal chromatic aberration is relatively large. At the same time, because the quantum dots are far away from the excitation light source, the light conversion efficiency is very low,...

However, for the backlight module using quantum dots, due to the uneven distribution of quantum dots on the film or the difference in the excitation efficiency of quantum dots at the edge and center of the film, the internal chromatic aberration is relatively large

At the same time, because the quantum dots are far away from the excitation light source, the light conversion efficiency is very low, resulting in low brightness of the entire module
