Abstract

The embodiment of the invention provides a holographic display device and a control method thereof, relates to the technical field of display, and can enlarge the problem that the viewing range of holographic display is limited. The holographic display device comprises a light source, a space light modulator, a first light guider, a second light guider, a locator and a direction controller, wherein the space light modulator is used for modulating reading light provided by the light source and emitting output light under the control of a write signal; the locator is used for detecting an observation position; the direction controller is used for setting the light path of the output light according to the observation position and outputting control signals to the first light guider and the second light guider respectively according to the light path; the first light guider is used for receiving the control signal and guiding the output light into the second light guider along the light path; and the second light guider is used for receiving the control signal and guiding emergent light converged by the first light guider into the observation position along the light path.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a holographic display device and a control method thereof. Background technique [0002] With the increasing popularity and use of 3D (Dimension, dimension) display technology, holographic display technology has gradually entered people's life and work. Holographic reproduction technology is different from parallax stereoscopic display technology, and has many advantages such as large depth of field and no vertigo. [0003] Usually, holographic display includes the recording of holographic images and the process of reproducing holographic images. On this basis, in order to realize dynamic holographic display, the recording process of holographic images can be performed through holographic calculation, and the coded data of holographic images can be obtained. Next, enter the above coded data into the Figure 1a The holographic image is reproduced in the holographic displ...
