Abstract
A simplified pixel display includes a plurality of pixel electrodes, a plurality of storage elements, a single arbitrary voltage supply terminal, a second voltage supply terminal which may be either of the rail voltages of the display, a common electrode, and a plurality of externally controlled switches each selectively coupling an associated one of the pixel electrodes with one of the arbitrary voltage supply terminal and the second voltage supply terminal responsive to a value of a data bit stored in an associated one of said storage elements and to the state of the external control signal supplied to the switch.
