  • System for correcting electron beam from single cathode in color CRT
    Patent number: 6239560
    Abstract: System for correcting an electron beam from a single cathode in an electron gun for a color CRT, in which the single electron beam emitted from the single cathode is controlled by a magnetic field generating device synchronous to an electron beam deflecting signal and a video signal applied to the cathode for realizing an optimal image, the system including 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
