Abstract

The invention discloses a light guide structure, a backlight module and a display device which are used for solving the problem of the low light utilization rate caused by large loss in the light propagation process by means of a light guide structure in the prior art. The light guide structure comprises a light guide plate, a reflective brightening film, a lambda / 4 wave plate and a reflective film, wherein the light guide plate comprises a light emission face, a reflective face and a side face, wherein the light emission face and the reflective face are arranged oppositely, and the side face is connected with the light emission face and the reflective face, wherein the light guide plate is made of an isotropic material; the reflective brightening film is arranged on the side, where the light emission face is located, of the light guide plate, the lambda / 4 wave plate is arranged between the light emission face of the light guide plate and the brightening film, and an included angle between the slow axis of the lambda / 4 wave plate and a transmission axis of the brightening film is 45 degrees; the reflective film is arranged on the side, where the reflective face is located, of the light guide plate.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a light guide structure, a backlight module and a display device. Background technique [0002] Liquid crystal display (Liquid Crystal Display, LCD) has the advantages of low radiation, small size and low energy consumption, and has gradually replaced the traditional cathode ray tube display (Cathode Ray Tube display, CRT) in some applications, so it is widely used in Notebook computers, personal digital assistants (Personal Digital Assistant, PDA), flat-screen TVs and mobile phones and other products. [0003] The liquid crystal display includes a display panel and a backlight module. The backlight module is a component that provides a light source for the liquid crystal display product. It is usually placed under the display panel to provide evenly divergent and certain brightness light to the display panel. According to the pixels on the display panel Different voltages of t...
