Abstract

See full text

A liquid crystal display with an identifier such as a watermark, serial number, logo or other graphic design, is disclosed. The identifiers can be read electronically or with the human eye. Methods are described for fabricating identifiers on cholesteric writing tablets in particular, with varying shades of gray and hence different degrees of visibility. The identifiers are permanent and not erased when a liquid crystal image on the display is erased.
