Light | High-fidelity 3D light field display with efficient information utilization
Author:
Introduction
Recently,Professor Sang Xinzhu and Professor Yu Xunbo's team from Beijing University of Posts and Telecommunicationsproposed a three-dimensional (3D) light field display technology that separately controls chromaticity and luminance information, significantly improving information utilization efficiency and achieving high-fidelity 3D display effects with full parallax and a wide viewing angle. This achievement is titled “High-fidelity light-field display with enhanced information utilization by modulating chromainance and luminance separately” and published inLight: Science & Applications，Zhang Zhaoh, a doctoral student at Beijing University of Posts and Telecommunications,is the first author of this paper,Professor Yu Xunbo from Beijing University of Posts and Telecommunicationsis the corresponding author.
The display system structure is shown in Figure 1, including a collimated light source, a luminance modulation film, a chromaticity modulation film, and a bidirectional angle modulation grating. A low-pixel-density chromaticity modulation film is used to control chromaticity information, and a high-pixel-density luminance modulation film is used to control luminance information, realizing the separation and control of chromaticity and luminance information. The light field display device realized by the above chromaticity and luminance separation control method has a field of view of 98.2° (horizontal) × 97.7° (vertical), a spatial resolution of 1000 × 1000, a display depth of 45 cm, and a number of viewpoints of 100 (horizontal) × 100 (vertical).

Compared with the traditional method with the same total amount of information, the light field display method that separates and controls chromaticity and luminance information is shown inFigure 2as shown below. The light field display with separated control of chromaticity and luminance information is clearer, and the display effect is significantly improved.

Applications and Prospects
In the future, it is planned to improve the information utilization efficiency of dynamic 3D light field display systems through a split-screen structure (low color depth, high pixel density luminance screen + low pixel density, high color depth chromaticity screen) to achieve high-quality 3D light field display effects.
