41.4: Advanced ASM Mode (Axially Symmetric Aligned Microcell Mode): Improvement of Display Performances by Using Negative Dielectric Liquid Crystal

Abstract

Abstract We have developed advanced Axially Symmetric Aligned Microcell Mode using negative dielectric liquid crystal (N‐type ASM mode) first in the world. Using compensation film for this N‐type ASM mode cell realizes the wide viewing angle of ±80° in all azimuths, and high contrast ratio of 300:1. The structure of this N‐type ASM mode panel is suitable for large‐sized display panels. This mode is applicable for such active display panels as TFT and PALC display, regardless of the difference of their drive systems. We consider that this N‐type ASM mode becomes(N‐type ASM mode) a key technology for the next‐generation monitors.
