Reflective GH-LCDs using a Bistable Switching Mode.

Abstract

A highly twisted nematic liquid crystal display (LCD) exhibits bistability of thc; 'up' and 'down' states when a holding voltage is applied. This device has the advantage of low cost driving without using active elements. In this study, the bistable device is applied to reflective guest-host LCDs, and t.he EO performance and switching performance of the device is evaluated. We will demonstrate the good bistability and the fast switching speed of this display mode.
