Interlaced colour cathode ray tube display with reduced flicker

摘要

An interlaced raster-scanned colour cathode ray tube display in which flicker is reduced by temporally off-setting one of the colours (preferably red) so that normally even-field data for that colour is displayed in the odd field and normally odd-field data for that colour 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 by of one scan line of the temporally shifted colour is compensated for by using the static and/or dynamic convergence circuitry.
