Holographic display panel, holographic display device and display method thereof

Abstract

The invention provides a holographic display panel, a holographic display device and a display method thereof, relates to the technical field of display, and is used for realizing dynamic holographic displaying. The holographic display panel comprises a plurality of field depth display units, wherein each field depth display comprises at least two pixels which are adjacent; each pixel comprises a plurality of sub pixels; each field depth display unit further comprises a plurality of phase plates; each sub pixel corresponds to a phase plate in the light exiting direction; and the phase plates are used for controlling diffraction angles of light exiting from the phase plates. The diffraction angles of the various phase plates corresponding to the sub pixels in the same pixel are the same, and the diffraction angles of light, which exit from the phase plates, of the different pixels in the same field depth display unit are different, so that oppositely elongated lines of the light exiting from the same field depth display unit are intersected at a field depth position.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a holographic display panel, a holographic display device and a display method thereof. Background technique [0002] With the continuous development of display technology, 3D (Dimension, dimension) display technology is increasingly popular and used. In the process of realizing 3D display, the user's left eye and right eye can receive different images. The above two images can form a stereoscopic image pair with horizontal parallax. Through the fusion of the brain, a stereoscopic image with a sense of depth is finally formed. image. However, since the images received by the user's left eye and right eye are different, users who watch the 3D display screen for a long time are prone to dizziness. [0003] In order to solve the above problems, a holographic display technology is proposed in the prior art, so that the images received by the left and right eyes of the user...

AI Technical Summary

Problems solved by technology

However, the amplitude and phase recorded on the holographic dry plate 23 cannot be changed after exposure, so only one stereoscopic image can be displayed

On this basis, even if the holographic dry plate 23 is superimposed and exposed, the number of interference images formed is limited, so that dynamic holographic display cannot be realized, and the user experience of holographic display is reduced
