High-transmittance Multi-domain Vertical Alignment Liquid Crystal Device with Protrusion Structure

High-transmittance Multi-domain Vertical Alignment Liquid Crystal Device with Protrusion Structure

We propose a high-transmittance multi-domain vertical alignment liquid crystal device with a protrusion structure. Disclination lines, which inevitably appear at the boundaries of domains in a multi-domain structure, can be reduced by adding a protrusion structure on the top substrate. The transmittance was improved by 11% using the proposed structure with no change of either the dark state or ...

Directed Vertical Alignment Liquid Crystal Display with Fast Switching

Fast vertical alignment mode with continuous multi-domains for a liquid crystal display.

We proposed a fast liquid crystal display (LCD) in a vertical alignment (VA) mode with continuous multi-domains for wide-viewing characteristics. The fast VA LCD was fabricated by the mixed vertical alignment layer with UV curable reactive mesogen (RM) polymer memorizing the switching directions of the LC molecules. The wide-viewing and fast response characteristics were obtained by axially sym...

6-2: Inverse Four Domain Twisted Nematic Liquid Crystal Mode for High Transmittance and Wide Viewing Angle Characteristics

In this paper, we fabricated the inverse four domain twisted nematic liquid crystal cell using stacked vertical alignment layer on planar alignment layer for strong azimuthal anchoring energy. That makes possible twist structures under applied voltage without chiral-dopant, as a result, high transmittance and wide viewing angle could be revealed.
