A holographic display panel, a holographic display device and a display method thereof

Abstract

The invention provides a holographic display panel, a holographic display device and a display method thereof, which relate to the field of display technology and are used for realizing dynamic holographic display. The holographic display panel includes a plurality of depth-of-field display units, each depth-of-field display unit includes at least two adjacent pixels, and each pixel includes a plurality of sub-pixels; each depth-of-field display unit also includes a plurality of phase plates, each sub-pixel along The light emitting direction corresponds to a phase plate, and the phase plate is used to control the diffraction angle of light emitted by the phase plate. The diffraction angles of the phase plates corresponding to the sub-pixels in the same pixel are the same, and the diffraction angles of light emitted by different pixels in the same depth-of-field display unit after passing through the phase plate are different, so that the light emitted by the same depth-of-field display unit, Its reverse extension line intersects at a depth of field 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
