Liquid crystal slit grating capable of being compatible with 2D (2 Dimension) and 3D (3 Dimension)

Abstract

The invention provides a liquid crystal slit grating capable of being compatible with 2D (2 Dimension) and 3D (3 Dimension). The liquid crystal slit grating comprises a first glass substrate, a second glass substrate, an upper polarizer, a lower polarizer, a first electrode, a second electrode and a liquid crystal material, wherein the upper polarizer and the lower polarizer are attached onto the outer surfaces of the first glass substrate and the second glass substrate; the first electrode is arranged on the inner surface of the first glass substrate; the second electrode is arranged on the inner surface of the second glass substrate; and the liquid crystal material is positioned in the center of the liquid crystal slit grating; the second electrode is a whole-surface conductive transparent material; the first electrode is divided into a plurality of bar electrodes; the bar electrodes are divided into a plurality of units; the units are independent from one another; and all the electrodes in each unit are connected together. The liquid crystal slit grating has the advantages as follows: 2D and 3D images can be presented at the same time, that is to way, the function of displaying the 3D images in one part of regions and the 2D images in other parts of regions is achieved by dividing the first glass substrate into a plurality of regions, enabling the regions not to be electrically conducted, and controlling one or more of the regions respectively.

Description

technical field [0001] The invention relates to stereoscopic display technology, in particular to a liquid crystal slit grating. Background technique [0002] Compared with head-mounted 3D displays such as color division, light division and time division, the autostereoscopic display technology based on parallax can objectively get rid of the shackles of ancillary equipment such as stereo glasses, improve viewing comfort and broaden the application field received widespread attention. Parallax barrier (parallax barrier) technology is a kind of autostereoscopic display technology. In order to realize the compatibility of 2D and 3D, whether it is a front barrier or a rear barrier, liquid crystal slit grating has been widely used. [0003] At present, the naked-eye 3D display technology of liquid crystal slit grating and 2D display screen realizes the compatibility of 2D and 3D. During 2D display, no voltage is applied to the liquid crystal slit grating, which has high transmi...
