Abstract

The invention belongs to the technical field of stereo display and provides a liquid crystal lens. The liquid crystal lens comprises a first substrate, a second substrate and liquid crystal molecules, wherein the first substrate and the second substrate are arranged oppositely, a plurality of first strip-shaped electrodes are arranged on the first substrate at intervals, a plurality of second strip-shaped electrodes parallel to the orientation of the first strip-shaped electrodes are arranged on the side, facing the first substrate, of the second substrate, and the two adjacent second strip-shaped electrodes are spaced by a certain distance. When the liquid crystal lens is used for 3D display, a plurality of liquid crystal lens units which are identical in structure and are distributed in an array mode are formed between the first substrate and the second substrate, each liquid crystal lens unit corresponds to one second strip-shaped electrode and at least two first strip-shaped electrodes, the width of the second strip-shaped electrodes is smaller than the distance of the liquid crystal lens units, and the central lines of the liquid crystal lens units and the central lines of the corresponding second strip-shaped electrodes are on the same straight lines. The invention further provides a stereo display device with the liquid crystal lens. Crosstalk can be obviously reduced, and the stereo display effect can be improved.

Description

technical field [0001] The invention belongs to the technical field of stereoscopic display, and in particular relates to a liquid crystal lens and a stereoscopic display device including the liquid crystal lens. Background technique [0002] In recent years, three-dimensional display technology has developed rapidly and has become a research hotspot. At present, stereoscopic display technology has important applications in fields such as medical treatment, advertising, military affairs, exhibitions, and games. The early stereoscopic display technology mainly used stereoscopic glasses to watch the stereoscopic images, but the current mainstream product is a naked-eye stereoscopic display device based on binocular parallax. At least two parallax images are respectively provided to the left and right eyes of the viewer, so that the viewer sees 3D images. [0003] figure 1 A structural schematic diagram of a stereoscopic display device provided in the prior art. The stereosc...
