Embodiment Construction

[0017] Such as figure 1 shown. The present invention consists of three liquid crystal cells superimposed, and the superposition sequence is red, green, blue, red, blue, green, green, red, and blue, etc. figure 1 Shown from top to bottom is a liquid crystal cell 1 reflecting red light, a liquid crystal cell 2 reflecting green light, and a liquid crystal cell 3 reflecting blue light.

[0018] Such as figure 2 shown. Each liquid crystal cell includes transparent electrodes 4 , cholesteric liquid crystal material 5 poured between the transparent electrodes 4 , a power source 6 electrically connected to the transparent electrodes 4 , and the power source 6 applies an electric field to the cholesteric liquid crystal material 5 through the transparent electrodes 4 .

[0019] Such as image 3 mentioned. There are two modes of operation for a single liquid crystal cell. When no voltage is applied, the liquid crystal cell works in the transmission mode, and when the voltage is app...

Abstract

The invention discloses a liquid crystal light valve curtain for an autostereoscopic display, which comprises three overlapped liquid crystal boxes. Polymer networked cholesteric liquid crystal materials are poured into the liquid crystal boxes, each liquid crystal box is a controllable transflective liquid crystal light valve curtain operated in a reflection mode and a transmission mode, and the reflection wavelengths of the three liquid crystal boxes are respectively a red center wavelength, a green center wavelength and a blue center wavelength when the three liquid crystal boxes are operated in the reflection mode.

Description

technical field [0001] The invention relates to the field of naked-eye stereoscopic display, in particular to a liquid crystal light valve screen used for naked-eye stereoscopic display. Background technique [0002] At present, 3D display technology is more and more widely used in people's life. In the prior art, the parallax-based naked-eye stereoscopic display methods for 3D display mainly include parallax barrier (front, rear) and lenticular. way. [0003] The parallax barrier type glasses-free multi-viewpoint 3D display technology uses a series of light-shielding stripes arranged in the vertical direction between the backlight module and the LCD panel to form a parallax barrier, which separates the images of the left eye and the right eye, so that 3D images can be obtained. The parallax barrier device is in front of the LCD. At present, the parallax barrier is generally realized by liquid crystal, which can control the switch of the parallax barrier, display 2D images...
