Abstract

The invention discloses a holographic liquid crystal display (LCD), a stereo display method and a stereo display system, wherein the holographic LCD stereo display system comprises a holographic projection device, a signal synchronous generator and a holographic LCD provided with a plurality layers of LCD panels. In the system, the holographic projection device decomposes a stored holographic stereo image to obtain decomposed images and projects the decomposed images to the holographic LCD in sequence, the holographic LCD controls the plurality layers of LCD panels to display the projected decomposed images in the projection sequence according to a received synchronous signal from the signal synchronous generator, when the frequency of the holographic LCD for displaying the decomposed images is not smaller than 46 HZ, the decomposed images form real three-dimensional stereo images in the human brain through the vision persistence effect of human eyes so that the holographic three-dimensional stereo images become stereo images in the holographic LCD and the vivid effect of displaying real naked eye three-dimensional images is achieved.

Description

technical field [0001] The invention relates to the technical field of three-dimensional display stereoscopic imaging, in particular to a holographic liquid crystal display (Liquid Crystal Display, LCD), a stereoscopic display method and a stereoscopic display system. Background technique [0002] Three-dimensional display technology is a display technology that uses a series of optical methods to make people's left and right eyes produce parallax to receive different pictures and form a three-dimensional effect in the brain. Currently, there are two commonly used naked-eye 3D display technologies: [0003] The first naked-eye 3D display technology: [0004] By using the brightness modulation type three-dimensional display, two two-dimensional display screens are sequentially arranged on the three-dimensional display at predetermined intervals on the viewer's line of sight, and the controller is used to control each two-dimensional display screen to display images respectiv...
