Advanced ASM mode (axially symmetric aligned microcell mode) : Improvement of display performance by using a negative-dielectric liquid crystal

We have developed an advanced axially symmetric aligned microcell mode using negative-dielectric liquid crystal (N-type ASM mode), the 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 a 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 1 displays, regardless of the difference of their drive systems. We consider that this N-type ASM mode will be a key technology for next-generation monitors.
