Three-dimensional display screen based on single-pixel liquid crystal lens

Abstract

The invention relates to a three-dimensional display screen based on a single-pixel liquid crystal lens in the technical field of liquid crystal displays, which comprises two substrates, a separant, liquid crystals, a linear polarizer, transparent electrodes, liquid crystal alignment layers, a pixel light source and a control circuit, wherein the two substrates are oppositely arranged, the two layers of transparent electrodes, the two layers of liquid crystal alignment layers, the separant and the liquid crystals are symmetrically arranged between the two substrates from two sides to the middle; and the outer side of either of the two substrates is sequentially provided with the linear polarizer and the pixel light source, and the control circuit is connected with the pixel light source and outputs a control signal. By reducing the distribution size of the refraction index of the lens formed by the liquid crystals to be about one pixel, the invention reduces the thickness of the liquid crystal layer and quickens the response speed of the liquid crystals, thereby improving the performance of three-dimensional display.

Description

technical field [0001] The invention relates to a device in the technical field of liquid crystal displays, in particular to a three-dimensional three-dimensional display screen based on a single-pixel liquid crystal lens. Background technique [0002] The three-dimensional display technology is a technology that makes the right and left eyes see a pair of parallax images with subtle differences, thereby producing a three-dimensional feeling. At present, the commonly used three-dimensional display technologies mainly include: wearing glasses, autostereoscopic display, volume three-dimensional, holographic stereoscopic display and so on. The basic principle of glasses-wearing 3D display technology is to use components such as polarized glasses or shutter glasses to control the parallax image pairs to enter the left and right eyes respectively; The light is separated in space, so that the observer can observe the parallax image pair without wearing glasses; volume display is ...

However, for the above-mentioned barrier method, it will cause most of the light loss, resulting in a decrease in screen brightness; for the above-mentioned liquid crystal lens method, it will not cause the loss of image light, but because the refractive index distribution of the liquid crystal lens formed by it needs to cover Several pixels require a relatively large thickness of the liquid crystal layer, which leads to a decrease in the response speed of the liquid crystal
