ABSTRACT:
Increasing the addressing capability of an optical image bar having a particular pixel center-to-center spacing (pixel pitch) is accomplished by employing a plurality of N electrodes per pixel. Compared to an optical image bar with one electrode per pixel, this provides N times as many locations for the electric potential transition which establishes the center of the pixel. The provision of multiple electrodes per pixel interval can be used to implement interlacing.
