Holographic display technology provides the ultimate solution for true 3D display, with enormous potential in augmented reality and virtual reality. However, the color and viewing angle of holographic 3D displays mainly depend on the wavelength of the laser and the pixel size of the current spatial light modulator. The inevitable color difference and narrow viewing angle in conventional systems seriously affect the holographic display effect, hindering the application of holographic 3D display in many fields.

In a new paper published in "Light: Science and Applications", a group of scientists led by Professor Qiang Hua Wang from Beihang University in China and their colleagues have developed a 3D display system with a large viewing angle based on color liquid crystal gratings. The proposed system displays a color perspective of 50.12 º without any color difference.

Beihang researchers use specially designed color liquid crystal gratings with the same diffraction angle to perform secondary diffraction on incident RGB light, expanding the viewing angle through secondary diffraction. Color liquid crystal gratings have three different spacing regions in a liquid crystal unit, corresponding to incident light of different wavelengths. In addition, a method for generating chromatic aberration free holograms has been proposed, which, in conjunction with color liquid crystal gratings, achieves large angle color display. By using the proposed system, 3D color objects can be vividly reconstructed without color difference and viewed from a large perspective.

The reported system solves the problems of small viewing angle and severe color difference in traditional holographic 3D display systems, and has good display effects and broad application prospects in medical, industrial and other fields.
