Abstract: An interlaced raster-scanned color cathode ray tube display in which flicker is reduced by temporally off-setting one of the colors (preferably red) so that normally even-field data for that color is displayed in the odd field and normally odd-field data for that color is displayed in the even field. The temporal shift can be either before or during storage of the bit patterns or during or after reading of the bit patterns. The resulting positional shift of one scan line of the temporally shifted color is compensated for by using the static and/or dynamic convergence circuitry.
