Embodiment Construction

[0053] The basic structure of the cholesteric liquid crystal reflective three-dimensional display screen of the present invention is an overlapping single screen, that is, two or three cholesteric liquid crystal two-dimensional display screens overlap to form a single screen. A combination of single-screen, in which there must be a pair of two-dimensional display cholesteric liquid crystal in opposite directions of rotation. According to this basic structure, the following three basic structures of the embodiments of application aspects are given as examples.

[0054] Structure of stereoscopic black and white display screen for portable black and white video camera (see image 3 and Figure 8 ):

[0055] Two left-handed and right-handed cholesteric liquid crystal two-dimensional display screens 12 and 13 overlap to form a single screen 14 . In this single screen 14, 8 is a substrate, 6 is an ink, and the screen 12 and the screen 13 are glued together with the glue 11 (also ...

Abstract

A cholester-phase reflection-type stereo LCD is composed of levorotary and dextrorotary cholester-phase LCDs, in which at least one pair of LCDs has opposite spiral structurcs. Its advantages includehigh definision, high resistance to moisture environment, low cost and power consumption, and high duty ratio.

Description

technical field [0001] The invention relates to a stereoscopic display device, in particular to a cholesteric liquid crystal reflective stereoscopic display device. Background technique [0002] 70% of the information obtained by humans comes from vision. Theoretical explanations of vision to objective perception are complex, but in immersive situations, it is recognized that there is a sense of depth. With the development of technologies such as computer graphics, communication, and simulated life, people require that this "sense of depth" can be reproduced in an immersive environment. [0003] There are many such depth-sensing technologies currently under development. Currently, there are two common applications: [0004] 1. Optical holographic stereoscopic display [0005] Please refer to [1] Teaching and Research Group of Optical Instruments of Tsinghua University, "Basic Information Optics" P249, Mechanical Industry Press (1985); [2] Cai Luzhong, Liu Huaguang, "Mo...
