Liquid Crystal Lens and Display Apparatus

Abstract

The present disclosure provides a liquid crystal lens and a display apparatus. The liquid crystal lens includes a first substrate and a second substrate arranged to be opposite to each other, a common electrode being provided on the second substrate; a liquid crystal layer interposed between the first and second substrates and including liquid crystal molecules; liquid crystal lens units, each of which includes a first group of strip-shaped electrodes and a second group of strip-shaped electrodes parallel to each other and spaced apart thereon, upon applying a voltage among the first and second groups, and the common electrode, a planoconvex lens is formed within the liquid crystal molecules between them, wherein each of the first and second groups includes layers of sub-electrodes insulated from each other, the sub-electrodes of the first and second groups are applied with a voltage, so as to adjust symmetry of the planoconvex lens.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims the benefit of Chinese Patent Application No. 201510053775.X entitled “Liquid Crystal Lens and Display Apparatus”, filed on Feb. 2, 2015 in the State Intellectual Property Office of China, the whole disclosure of which is incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]Field of the Invention[0003]The present invention relates to a technical field of display, more particular to a liquid crystal lens and a display apparatus.[0004]Description of the Related Art[0005]The existing 3D display apparatus normally employs a liquid crystal lens provided on a 2D display panel. Currently, the liquid crystal lens is mainly formed as follows. As shown in FIG. 1, a planoconvex lens is formed by two strip-shaped electrodes, which are applied with equal voltages. Each strip-shaped electrode makes the liquid crystal molecules therebetween to generate the same degree of defection, thereby forming the planoconvex lens...

AI Technical Summary

Benefits of technology

The present invention aims to address the shortcomings of existing technologies. The technical effect of the invention is to ensure that the planoconvex lens formed in the liquid crystal molecules remains highly symmetrical even at an angle between the direction of simulated section and the light transmission axis of the 2D display panel.

Problems solved by technology

Rubbing direction are perpendicular to the simulated section and there is a certain angle between the simulated section and the light transmission axis of the 2D display panel as shown in FIG. 2, it is difficult to guarantee the formed planoconvex lens to have the relatively high symmetry and the phase delay.

The symmetry is relative low, resulting in large crosstalk and relatively small phase delay.
