摘要:
A display includes: an image data storage unit that stores image data; a display image data generation unit that synthesizes the image data with data of a noise pattern image with no correlation to the image data, and generates display image data; and a display unit that displays an image based on the display image data generated by the display image generation unit, and maintains a display without power supply.

A method of driving a liquid crystal display element having a cholesteric liquid crystal is provided. The driving method includes a first step for driving a liquid crystal for a relatively short voltage application period after resetting the liquid crystal at pixels to a planar state to display preliminary gray levels and a second step for driving the liquid crystal for a voltage application period longer than the above voltage application period to display desired gray levels.

摘要:
An electrification enhancer is either contained in the photoconductor, is present as a coating on the surface thereof, or is applied prior to use. A compound such as ammonium fluoride, a ferroelectric substance, a high molecular substance (fluorine resin) with an equivalent work function of 4.10 or greater, etc. are effective. The chargeability of the photoconductor is improved. The construction is best suited for the rear photorecording process, but is also effective in other types of contact charging recording systems.
