P‐100: Driving Technique for Grayscale in Dual‐Antiferroelectric Liquid Crystal Display

Abstract

When an antiferroelectric liquid crystal (AFLC) cell is set between crossed polarizers for optical modulators or displays, it has low transmittance efficiency. This happens because AFLC materials have inherent tilt angles of typically 18°~ 38°, not 45°. To improve the low transmittance efficiency, we propose a new optical configuration for antiferroelectric liquid crystal displays, which also improves color dispersion. We compare the Dual-AFLCD with a conventional AFLCD by simulation and experiment with the fabricated cells, and grayscale characteristics of this Dual-antiferroelectric liquid crystal display are estimated from the experiments in this paper.
