Maxwellian View

The Maxwellian view offers a promising approach to overcome the vergence-accommodation conflict in near-eye displays, however, its pinhole-like imaging naturally limits the eyebox size. Here, a liquid crystal polymer-based Dammann grating with evenly distributed energy among different diffraction orders is developed to enlarge the eyebox of Maxwellian view displays via pupil replication. In the experiment, a 3-by-3 Dammann grating is designed and fabricated, which exhibits good efficiency and high brightness uniformity. We further construct a proof-of-concept Maxwellian view display breadboard by inserting the Dammann grating into the optical system. The prototype successfully demonstrates the enlarged eyebox and full-color operation. Our work provides a promising route of eyebox expansion in Maxwellian view displays while maintaining full-color operation, simple system configuration, compactness, and lightweight.

Display Performance

Liquid crystal display (LCD) is one of the most dynamic electronic products in this century. It has been recognized as a key component of media era, since it has many characteristics, such as a low operating voltage, light volume, and excellent performance of full color display, and suitable for LSI drive and the like. In order to break the limitations of LCD, improve its animation display performance as multimedia television monitor, and strongly simplify the manufacturing to ensure the competitiveness on price, we designed a LCD module with the liquid crystal cell of TD-EDA experimental system based on FPGA, and achieved the control of LCD with hardware description language VHDL in this paper. The validation results of compiled program downloaded on programmable logic devices after compiling and simulating show that the LCD we designed can run correctly and relatively perfectly.

The demand for color head- and helmet-mounted displays (HMDs) is growing. Interest focuses on full-color systems, but a limited color repertoire is sufficient for some applications and can reduce cost and complexity significantly, especially when subtractive-color active-matrix liquid-crystal display (AMLCD) technology is used. We report a series of experiments that investigated important questions about the design and merits of two-primary color AMLCDs for HMD applications. Our main conclusion is that the image quality of a subtractive-color AMLCD with high (≥70%) aperture ratio is superior to a comparable, conventional color AMLCD. Evidence regarding requirements for resolution, aperture ratio, and gray scale is also provided.
