Reducing the color shift of a multidomain vertical alignment liquid crystal display using dual threshold voltages

Directed Vertical Alignment Liquid Crystal Display with Fast Switching

Hybrid anchoring for a color-reflective dual- frequency cholesteric liquid crystal device switched by low voltages

Cholesteric liquid crystal (CLC) materials used in electro-optical (EO) devices are characterized by high operating voltage and slow response speed, which hinders their further development in display applications. Dual-frequency CLCs (DFCLCs) can solve the problem of slow bistable transition, but the operating voltage is still high, especially in color-reflective DFCLC cells. Here we report a s...

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...

The development of self-assembled liquid crystal display alignment layers.

From simple pocket calculators to mobile telephones and liquid crystal display (LCD)-TV, over the past few decades, devices based on LCD technology have proliferated and can now be found in all conceivable aspects of everyday life. Although used in cutting-edge technology, it is surprising that a vital part in the construction of such displays, namely the alignment layer, relies essentially on ...

Multiprimary color display for liquid crystal display projectors using diffraction grating

Takeyuki Ajito Takashi Obi Masahiro Yamaguchi Nagaaki Ohyama Tokyo Institute of Technology Imaging Science and Engineering Laboratory 4259 Nagatsuta, Midori-ku Yokohama, 226-8503 Japan E-mail: [email protected] Abstract. To reproduce the natural color of an object through color imaging systems, the range of the reproducible color, i.e., the color gamut, of the color display devices must be...
