Liquid crystal lens and stereo display device

Abstract

The invention provides a liquid crystal lens and a stereo display device. The liquid crystal lens comprises a first substrate, a second substrate and a liquid crystal layer, the second substrate is provided with a plurality of strip electrode assemblies, each strip electrode assembly comprises at least two layers of electrode stripes, the width of the at least two layers of electrode stripes decreases in order, one of the at least two layers of electrode stripes is divided into a first sub electrode stripe and two second sub electrode stripes, the two second sub electrode stripes are arranged on two sides of the first sub electrode stripe at intervals, and the first sub electrode stripe is electrically connected with another electrode stripe which is the most adjacent to an electrode stripe, far away from the second substrate, of the at least two layers of electrode stripes. The liquid crystal lens and the stereo display device have the advantages that not only can the switching of the 2 dimensional (D) / 3D display be conducted, but also the resistance of the electrode stripes can be reduced, the capacitance of the strip electrode assemblies is reduced at the same time, and the delay phenomenon of remote control (RC) of the strip electrode assemblies is reduced.

Description

technical field [0001] The invention relates to the technical field of stereoscopic display, in particular to a liquid crystal lens and a stereoscopic display device. Background technique [0002] The current stereoscopic display devices generally adopt autostereoscopic display, that is, naked-view 3D (Three Dimensions, three-dimensional) display, which mainly uses light-splitting devices such as liquid crystal lenses installed on the light-emitting side of the 2D (Two Dimensions, two-dimensional) display panel to display The left and right parallax images displayed on the panel are respectively sent to the left and right eyes of the observer, and then fused by the brain so that the observer can obtain stereoscopic perception. [0003] Among them, optical splitting devices such as liquid crystal lenses mainly use transparent materials to make cylindrical lens arrays of a certain size, and through their refraction, the light of different pixels in the display panel is emitted...

Problems solved by technology

However, in the structure of the large-size liquid crystal lens 100, the width of the electrode strips adjacent to the liquid crystal layer is large, and the corresponding resistance is large, resulting in a large capacitance of the strip-shaped electrode group, so it is very easy to produce serious resistance-capacitance delay phenomenon (RC Delay ), resulting in insufficient charging of the rear end of the liquid crystal lens 100, thus affecting the viewing effect of 3D display
