Problems solved by technology

However, we can imagine that the 3D display obtained by this kind of liquid crystal column lens with a strip structure is directional, and the viewer can only watch the 3D effect from certain specific directions; in addition, the viewing angle is discontinuous , there will be a shear zone in the middle, if the viewer happens to be in the shear zone, not only can’t see the tangential 3D image, but also easily cause dizziness and other discomfort symptoms

Abstract

The invention provides a liquid crystal lens array and a stereoscopic display apparatus, and relates to the technical field of stereoscopic display. The liquid crystal lens array includes a plurality of liquid crystal microlens units, wherein each liquid crystal microlens unit includes a first glass substrate and a second glass substrate; the first glass substrate is plated with a first electrode; the second glass substrate is plated with a second electrode; liquid crystal is filled between the first glass substrate and the second glass substrate; and the first electrode includes a circular electrode at the center position, and at least two annular electrodes which are arranged in the shape of a concentric ring and take the circular electrode as the center. As the 3D display effect formed by the liquid crystal lens array has no directionality, a user can watch the required 3D effect from a wider angle, and the watching angle is more continuous, so that the 3D display effect of a stereoscopic display apparatus using the liquid crystal lens array becomes better and has no shear zones and the problem that the watcher becomes giddy because of being in the shear zone is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of stereoscopic display, in particular to a liquid crystal lens array and a stereoscopic display device. Background technique [0002] The display industry has gone through many stages. With people's continuous pursuit of display effects, display technology has continued to improve, from static to dynamic, from black and white to color, from small size to large size, from bulky CRT to flat panel display; Display is facing the strong impact of stereoscopic (hereinafter referred to as 3D) display. Glasses-free 3D display technology and wearable 3D technology have both developed rapidly. Compared with wearable 3D technology, glasses-free 3D technology has the huge advantage of not needing to wear various auxiliary equipment, and the viewer is more free. [0003] At present, there are three-dimensional display devices that use liquid crystal lenses to realize naked-eye 3D display, which mainly utilizes positive...
