A liquid crystal lens and a naked-eye three-dimensional display device comprising the liquid crystal lens

Abstract

The invention relates to the technical field of display, and particularly relates to a liquid crystal lens, which is characterized by comprising a first transparent substrate, a first dielectric layer, a first electrode, a first alignment layer, a second transparent substrate, a second electrode, a second alignment layer and a liquid crystal layer, wherein the first dielectric layer is in strips, zigzags or steps, which are spaced and arranged in parallel on the upper surface of the first transparent substrate; and the thickness of the first dielectric layer is stepwise increased in the direction from the center of the liquid crystal lens to the edge of the liquid crystal lens. According to the invention, the dielectric layer stepwise distributed is used to form a liquid crystal lens and a naked-eye stereoscopic display device with the liquid crystal lens, the device not only can achieve free switching between 2D (two dimension) and 3D (three dimension) and but also can achieve time-share switching of left-eye and right-eye images so as to achieve effects of a dynamic liquid crystal lens, and finally a full high definition stereoscopic display image is obtained.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a liquid crystal lens and a naked-eye three-dimensional display device comprising the liquid crystal lens. Background technique [0002] With the development of display technology, the application of stereoscopic display devices is becoming wider and wider. The three-dimensional display device provides two images displayed on the flat-panel display to the left and right eyes of the viewer through the grating and other optical components, and then the viewer's brain can synthesize the two parallax images to perceive a three-dimensional image . There are generally two types of stereoscopic display devices: a slit grating type stereoscopic display device and a microlens array stereoscopic display device. Among them, the slit grating type includes film type, black matrix type, reflective type, and liquid crystal grating type, etc., while the microlens array can realize 2D / 3D switc...

AI Technical Summary

Problems solved by technology

It can be seen that the resolution of the slit grating stereoscopic display or the liquid crystal lens stereoscopic display device can only reach half of the resolution of the display panel, so the displayed 3D image cannot be applied to some occasions requiring high resolution
