Optimization of a single-polarizer reflective TN-LCDs with one liquid crystal polymer film and one retardation film

Abstract

The reflective color LCD is an important device tbr highly functional portable information terminals. In this paper, we numerically analyzed the electro-optical properties of the previously proposed single polarizer reflective TN-LCD with one LC polymer film and one retardation film. We found that the LCD using the typical LC polymer film with a large dispersion of Δ n exhibits a high contrast ratio and a high luminous reflectance when the retardation of LC polymer film and the driving TN cell are optimized to different values.
