ABSTRACT:
Static electrical-field address of an electro-optic panel having opposing first and second dielectric surfaces sandwiching a two-dimensional light-modulating region is accomplished by: (i) applying a reference potential sequentially to successive lines of the first surface and (ii) applying, in synchronism with each such reference potential application and in accordance with image line information, separate signal potentials to the plurality of discrete pixel address zones located along a line of the second surface that is directly opposite such reference potential application. A two-dimensional electrostatic charge pattern corresponding to the image is formed on the one surface. Thereafter, ground potential is applied to portions of the first surface contiguous the charge pattern and portions of the second surface directly opposite the charge pattern.
