ABSTRACT:
A hybrid CRT display includes vector generated portions for alpha-numeric data and normal raster scan portions for symbol data. A deflection yoke for a CRT is driven by a single horizontal amplifier having switching means which operate the amplifier in three modes necessary to achieve the hybrid display, enhanced by resonant retrace during raster scanning.
