IMPROVEMENTS RELATING TO LINE SCAN CIRCUITS FOR CATHODE RAY TUBE DISPLAYS Abstract A line scan circuit for a cathode ray tube display includes a phase detector, integrator, voltage controlled oscillator and line output stage. The integrator, volt- age controlled oscillator and line output stage are con- ventional but the phase detector is novel. The phase detector compares the phase difference for both the lead- ing and trailing edges of the horizontal synchronization pulses and the line flyback pulses. This forces the line flyback pulses to be centred with respect to the synchron- ization pulses resulting in improved centring and linear- ity of the displayed picture. UK9-79-011
