Abstract

The invention discloses a light guide plate, comprising a light incoming surface and a bottom surface, where one of them has a mesoporoes structure, and the mesoporous structure comprises a plurality of mesopores, a plurality of first-order nano particles and a plurality of second-order ones, where these first-order nano particles are arranged in the mesopores and these second-order nano particles are arranged between the mesopores.

Description

【Technical field】 [0001] The invention relates to a light guide plate, in particular to a light guide plate used for a liquid crystal display panel. 【Background technique】 [0002] As liquid crystal display panels (Liquid Crystal Panels) are more and more used in mobile phone displays, portable DVDs and portable computers, there is a higher requirement for the brightness of the backlight modules used in the liquid crystal display panels. When the light beam emitted by the light source is transmitted in the light guide plate, most of the light beam is lost inside the light guide plate, and only a small part of the light beam is emitted through the light-emitting surface of the light guide plate. Therefore, researchers continue to improve the technology of the light guide plate in order to reduce the loss of the light beam propagating in the light guide plate, increase the intensity of the light beam emitted from the light-emitting surface of the light guide plate, and thereby...
