Abstract

The invention relates to a light guide plate applicable to a polarized backlight and the polarized backlight. The light guide plate comprises a light incident surface, a light emergent surface, a first surface and a microarray, wherein the light emergent surface is connected to the light incident surface; the first surface is connected with the light incident surface and is basically parallelly with the light emergent surface; and the microarray is arranged on the first surface and comprises multiple parallelly-arranged micro structures, the micro structure extends along a direction vertical to the light incident surface, the microarray and the light incident surface are separated, and a gap exists. The light guide plate is configured to propagate natural light incident from the light incident surface in a total reflection mode. With the help of the laterally-distributed micro structures, the light guide plate can improve the uniformity of the polarized light emitted from the polarizedbacklight in the lateral direction.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a light guide plate and a polarized backlight that can be used for a polarized backlight. Background technique [0002] Flat panel displays, such as liquid crystal displays (LCDs), are essential components of many types of electronic equipment. As a passive light-emitting device, a liquid crystal display relies on a backlight on the back of the display to illuminate the screen. Due to the display requirements of liquid crystal flat panel displays, the light that is effectively used is light with a specific polarization direction. For traditional backlight sources that emit natural light, the utilization rate of the final light intensity is often less than 5% of the original light intensity, and the light loss is very high. If the lost light is not reused, it can cause adverse effects such as temperature rise. In order to solve this problem, one of the solutions ...
