Abstract

The invention discloses a display device and a method for implementing holographic display thereof. A plurality of first lenses closely arranged in an array manner constitute a first lens array, and each of the first lenses corresponds to a plurality of observation regions arranged on a light outgoing path respectively; a plurality of slits arranged in an array manner and corresponding to the first lens one by one constitute a slit array; a spatial light modulator loads a holographic image; a human eye tracking device tracks the position of human eyes; a controller determines an observation region according to the position of the human eyes, then controls a deflection element to direct the exit light of the spatial light modulator to the slit corresponding to the first lens corresponding to the observation region, and controls the deflection angle of the first lens to converge the exit light of the first lens to the position of the human eyes. Because the controller can control the deflection of different angles of the first lenses according to the position of the human eyes, the holographic image can be accurately converged at the position of the human eyes, thereby overcoming theproblem that the viewing angle is limited in the holographic window technology.

Description

technical field [0001] The invention relates to the technical field of holographic display, in particular to a display device and a method for realizing holographic display. 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. Holographic display technology can be divided into two types: static and dynamic. Static holographic display technology is basically mature, and it is more common in exhibitions, advertisements, etc. Although dynamic holographic display technology is still in the research stage, it has broad application prospects and has become a research hotspot in the field of holographic and three-dimensional display technology. At present, the dynamic display ba...
