Abstract
ABSTRACT Reflective liquid crystal displays are attracting attention as portable information systems because of zero- or extremely low power consumption. In this study, we deal with an electrode-free reflective liquid crystal cell, where image formation is achieved by coating one of the substrates with optically active azo dye thin film. To describe reflective characteristics of the cell, we develop a simulation model based on a continuum theory with the successive solution of the Maxwell equations for light propagating in anisotropic liquid crystal media. Computation of reflective characteristics was carried out by using the 8 × 8 transfer matrix method, which is the solution of Maxwell equations. By changing boundary conditions, we have obtained different reflectance coefficients (from ~0.03 to 0.43), and the corresponding chromatic colours were generated. Our results were obtained by using the modelling and optimisation system MOUSE-LCD.
