Abstract
A system for applying grey scale codes to a display device having a plurality of columns of pixels, has a segmented shift register, with one shift register segment for each pixel column. Data stored in the shift register segments are transferred to counters through multiplex circuitry. The counters control transfer gates by which voltages are applied to the pixel columns.
