ABSTRACT:
A tri-color cathode ray tube has three DC voltage supplies and three strings of triacs. Each string is coupled between one of the supplies and the anode of the cathode ray tube for selectively applying the voltage from the one supply to the anode. The tri-color display is provided by directing an electron beam from the cathode of the cathode ray tube to beam penetration phosphors on the display screen of the cathode ray tube which selectively produce colors in response to the beam and the selected voltage applied thereto.
