Embodiment 1

[0035] Such as Figure 1 to Figure 8 As shown, this embodiment provides a holographic display device, which includes:

[0036] An imaging unit, which is divided into a plurality of imaging areas 11, each imaging area 11 is used to independently form a holographic image 9;

[0037] A light source unit comprising a plurality of light sources 2 arranged in an array for providing light to the imaging unit;

[0038] Human eye tracking unit 3, which is used to determine the position of human eyes;

[0039] The control unit 4 is used to control at least part of the light source 2 and the imaging area 11 to be turned on for holographic display according to the position of the human eye, where the light emitted by the turned on light source 2 passes through the turned on imaging area 11 and can be directed to the position of the human eye.

[0040] Such as figure 1 As shown, in the holographic display device of this embodiment, the light source unit includes a plurality of light sou...

Embodiment 2

[0064] This embodiment provides a display method of a holographic display device, and the holographic display device used is the above-mentioned display device; the display method specifically includes:

[0065] The human eye tracking unit is used to determine the position of human eyes;

[0066] The control unit controls at least part of the light source and imaging area to be turned on for holographic display according to the position of the human eye, wherein the light emitted by the turned on light source can be directed to the position of the human eye after passing through the turned on imaging area.

[0067] That is to say, when the above holographic display device is used for display, the human eye tracking unit should be continuously used to determine the position of the human eye, and some light sources and imaging areas should be selected for holographic display according to the current position of the human eye, so as to ensure that the currently turned on light sou...

Abstract

The present invention provides a holographic display device and a display method thereof and belongs to the holographic display technology field. An existing holographic display device is small in a visible range and can be only viewed by a single person, while, with the holographic display device and the display method thereof of the invention adopted, the above problems can be solved partially at least. The holographic display device of the present invention includes an imaging unit, a light source unit, a human eye tracking unit and a control unit; the imaging unit is divided into a plurality of imaging regions, wherein each imaging region is used for independently forming a holographic image; the light source unit includes a plurality of light sources arranged in an array and is used for providing light for the imaging unit; the human eye tracking unit is used for determining human eye positions; and the control unit is used for controlling and making at least a part of the light sources and the imaging regions turned on to perform holographic display according to the human eye positions; and after passing through turned-on imaging regions, light emitted by turned-on light sources can be emitted to the human eye positions.

Description

technical field [0001] The invention belongs to the technical field of holographic display, and in particular relates to a holographic display device and a display method thereof. Background technique [0002] Holographic display technology is a display technology that uses the principles of interference and diffraction to record and reproduce the real three-dimensional image of an object. It can display all information from all angles of the object and is considered to be the ultimate solution for realizing three-dimensional display. [0003] As we all know, holographic reproduction technology is different from inspection stereoscopic display technology. It has many advantages such as large depth of field and no dizziness. However, the development of holographic reproduction technology, especially video holographic reproduction technology, is also restricted by hardware conditions. On the one hand, this technology The spatial light modulator is required to have very high re...
