ABSTRACT:
A method for the conversion of conventional interlaced video display synchronization signals to those required for a field sequential color display interlaced video synchronization signals comprises the steps of receiving the conventional horizontal and vertical synchronization signals; multiplying the repetition rates of these signals by a factor that is number of component colors that comprise the colors of the video display; selecting time segments of the multiplied horizontal synchronization signals; phase shifting these selected time segments to align with the multiplied vertical synchronization signal; merging the phase shifted and the non-phase shifted time segments of the multiplied horizontal synchronization signal to form the field sequential color display horizontal synchronization signal; and amplifying and buffering the multiplied vertical synchronization signal and the field sequential color display horizontal synchronization signal to act as input to the deflection circuitry of a field is sequential color display.
