Abstract:
A system for correcting an electron beam from a single cathode in an electron gun for a color CRT comprising:a time division distributor for receiving a video signal and generating one of electron beam signals corresponding to a red, a green, or a blue fluorescent material;an electron gun with a single cathode for receiving any one of red, green, blue signals from the time division distributor and emitting a single electron beam;a deflection yoke for receiving a deflection signal and deflecting the electron beam emitted from the cathode to an entire region of a screen;a digital controller for receiving a signal from the time division distributor and the deflection signal; and,a magnetic field generating device for receiving a signal from the digital controller and correcting the electron beam in advance before deflection of the electron beam to a preset position.
