P‐153: High Contrast Ratio LCD with an In‐cell Polarizer

Abstract

We develop a rigorous model to simulate an LCD's contrast ratio (CR) and viewing angle by considering the depolarization effect. To improve CR, an in‐cell polarizer is added between LC layer and color filter array. The obtained maximum CR of a multi‐domain vertical alignment LCD is boosted to > 20,000:1.
