Paper Abstract

The problems of analog gray scale in SSFLC are studied under different driving conditions with the aim to relate their behavior in real display devices. It is shown that electrooptic behavior of uniform chevron texture in transient levels is not stable enough under cross-talk free driving with random cross-talk data pulses. Non-uniform texture, obtained with low-frequency treatment of SSFLC, reproduces gray levels much better, but some kind of image sticking, which is not visible with conventional methods of studying electrooptic properties, is still observed. Special method of registration of sticking is proposed to make tests more reliable.
