Device and method of liquid display

Abstract

The invention discloses a device and a method of liquid display. The device of the liquid display comprises a first liquid crystal panel, a backlight module, an optical medium layer and a second liquid crystal panel. The first liquid crystal panel is used for displaying an image which corresponds to an image signal through a first sub-pixel on the first liquid crystal panel based on the image signal received by the device of the liquid display. The backlight module is arranged on the rear of the first liquid crystal panel, and is used for providing a light source for the first liquid crystal panel. The optical medium layer is arranged in front of the first liquid display panel, wherein the thickness of the optical medium layer is a first thickness value. The second liquid crystal panel is arranged in front of the optical medium layer. Each second sub-pixel on the second liquid crystal panel has a light conducting state and a light closing state, and the light conducting state and the light closing state of each second sub-pixel can be independently controlled. The distance between the first liquid crystal panel and the second liquid crystal panel through the optical medium layer is the first thickness value.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a liquid crystal display device and method. Background technique [0002] At present, 3D display devices have been widely popularized, but users need to wear corresponding 3D glasses when watching. discounted. Therefore, naked-view 3D display technology without wearing glasses has become the direction and goal of continuous development. [0003] Currently, naked-view 3D display technologies generally include two types: slit grating type and lenticular lens type. [0004] However, the traditional grating-type naked-view display device cannot realize the conversion between 2D / 3D, which brings inconvenience to use. Therefore, there is an urgent need for a naked-view device capable of automatically switching 2D / 3D, which can realize 2D / 3D mode switching according to the format of an input image signal. [0005] In order to solve this problem, the industry conducts a lot of r...

AI Technical Summary

Problems solved by technology

[0009] The present application provides a liquid crystal display device and method, which solves the technical problems in the prior art that the production process is complex due to the use of lenses to switch between naked-eye 2D / 3D modes; and the number of viewpoints of the display device cannot be changed.
