ABSTRACT:
A dynamic new circuit is disclosed which permits an extremely high resolution cathode ray tube display. Utilizing this circuit, horizontal drive operating frequency may be increased by a factor of approximately four and video drive operating frequency may be increased by a factor of approximately ten. Improved circuits for horizontal drive, vertical drive, video drive and associated circuitry are disclosed which cooperate to produce a high frequency display which has unparalleled clarity and resolution.
