A New Drive Method for Electrically Controlled Birefringence Liquid Cristal Displays and Development of their Viewing Performances.

Abstract

Electrically Controlled Birefringence (ECB) LCDs are one possible candidate for reflective color LCDS, because their color gamut is as wide as that of backlighted color LCDs. However, conventional LCD drive methods are not applicable on ECB LCDs. To increase the number of reproduction colors and realize full color reproduction, we proposed a new drive method for PCB LCDs using additive mixing of chromatic colores and achromatic colores. Furthermore, viewing performances of ECB LCDs using the new method are discussed.
