P‐180: Enhancement of Predictability for Optical Properties of LC Simulator

Abstract

The predictability of a Liquid Crystal simulator has been investigated. Three critical parameters for the simulator i.e., transmittance, response time and viewing angle, were determined. The optimization was performed through elaborative correlation between experimental and simulation results. The results with optimized parameters show good agreement with experimental results within an error tolerance of 10%. The determined main parameters regarding each optical property are summarized and discussed.

“…In the past, several alternative schemes [2][3][4][5] for polarizer-free modulation have been pursued, but with limited success, owing to fabrication challenges that manifest as low contrast ratios, limited acceptance angles, or low optical throughput. Our initial attempts with electrically switchable PGs [6][7][8][9][10][11] were successful in developing a polarizer-free LCOS based projection display [12] with high optical throughput and reasonable contrast ratios.…”
