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

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.
