Abstract:
A liquid crystal writing device includes a dispersion of cholesteric liquid crystal and polymer; a flexible substrate on which a user applies pressure that changes a texture of the cholesteric liquid crystal to form an image; electrically conductive layers between which the dispersion is disposed; and electronics adapted to apply an erase voltage waveform across the electrically conductive layers that forms a focal conic texture and erases the image. The erase voltage waveform includes: i) an erase portion at an erase voltage VE, the erase voltage VE being at least as high as a planar to homeotropic transition start voltage (VPH 0 ) of the cholesteric liquid crystal, and ii) a slow discharge portion that lasts for a time t d  that is at least 10 ms.

Claim (Index 2):
The liquid crystal writing device of  claim 1  wherein said time t d  is any of the following: at least 25 ms, at least 50 ms, at least 56 ms, at least 64 ms, at least 80 ms; at least 150 ms, at least 0.5 second, at least 1 second; at least 2 seconds; at least 3 seconds; and at least 10 seconds.
