P‐130: An Advanced Cumulative Drive Scheme for Fast Refreshed Cholesteric LCD

Abstract

Fast refresh rate is desirable for inherently slow updated passive matrix (PM) cholesteric liquid crystal display (Ch-LCD). This paper proposes a flexible cumulative drive scheme for fast and optimally refreshed PM Ch-LCD. The proposed drive scheme was experimentally verified on a 5" 100ppi PM Ch-LCD and satisfactory results were obtained.
