Nanowire grid polarizer for energy efficient and wide-view liquid crystal displays

Zhibing Ge, Shin-Tson T. Wu

Abstract

We report a liquid crystal display (LCD) using a nanowire grid polarizer (NWGP) to replace the bottom sheet linear polarizer (LP). The top LP and bottom NWGP configurations enable backlight recycling for enhancing optical efficiency while keeping a high contrast ratio and wide viewing angle. The electro-optic performance of this device configuration is studied based on the effective-medium theory and 4×4 matrix method. Results show that this configuration exhibits a 100:1 contrast ratio over 75° viewing cone in a film-compensated multidomain vertical alignment LCD and 10:1 over 65° viewing cone in a fringe-field switching LCD without any compensation film.
