HOLOGRAPHIC LIQUID CRYSTAL DISPLAY, STEREO DISPLAY METHOD, AND STEREO DISPLAY SYSTEM

摘要

A holographic LCD stereo display system is disclosed. The holographic LCD stereo display system comprises: a holographic projection device (11), a signal synchronous generator (12) and a holographic LCD having multiple layer of LCD panels. In the system, the holographic projection device (11) decomposes a stored holographic stereo image to obtain decomposes images and projects the decomposed images to the holographic LCD (13) in sequence; the holographic LCD (13) controls, according to a synchronous signal received from the signal synchronous generator (12), the multiple layers of LCD panels to display projected decomposed images in sequence; and when a frequency at which the holographic LCD (13) displays the decomposed images is not less than 46 Hz, with visual persistence effect of human eyes, the decomposed images become real three-dimensional stereo images in human brains, so that the holographic stereo three-dimensional images are presented stereo images in the holographic LCD (13), thereby achieving an effect of vividly displaying real naked-eye three-dimensional images. Further disclosed are a holographic LCD and a stereo display method.

1. A holographic LCD, comprising a layer-by-layer scan synchronous driver circuit and multiple LCD panels, wherein:
the layer-by-layer scan synchronous driver circuit determines a refresh frequency at which decomposed images obtained by decomposing the holographic stereo image are projected, controls the multiple LCD panels to display in sequence the decomposed images projected, and in a refresh period, controls only one panel of the multiple LCD panels to display the decomposed image projected and other panels of the multiple LCD panels to be in a fully transmissive state according to the refresh frequency; the LCD panel displays the decomposed images projected or enters the fully transmissive state under the controls of the layer-by-layer scan synchronous driver circuit.
