ABSTRACT ENHANCED DATA DISPLAY SYSTEM Display of alphanumeric characters and other symbols generated in a dot-matrix form on a CRT is enhanced by modulating the CRT beam sinusoidally at the dot matrix clock rate to produce one full cycle of modulation for each dot space with a phase to display a dot on a slope between modulation maxima of opposite polarity. The phase and am- plitude of the modulation is selected to place the q dots displayed in a dot space between the modulation maximum of one polarity and a maximum of opposite polarity for each dot space of an MxN matrix, with a depth of modulation of ? 1/4 raster scan spacing of the CRT.
