Abstract

AbstractWe have designed drive schemes which can update gradually the content of a bistable reflective cholesteric display. These scheme make use of the “kicking” effect as in addressing STN displays. The cholesteric material is kicked from the planar texture to the focal conic texture step‐by‐step or vice versa. We have also developed a new cholesteric display cell structure which has a 2 ms homeotropic‐planar transition time. Using the new cell structure and the new drive scheme, we have achieved an addressing speed of 0.5 ms/line; the cholesteric display can be operated at a quasi‐video rate.
