ABSTRACT:
An improved apparatus for driving a cathode-ray tube (CRT) with minimized power consumption is disclosed. In the apparatus, a voltage regulator element (a Zener diode) supplying a regulated voltage substantially equal to that voltage of the associated cathode providing a maximum image luminance is connected in series with the cathode between the driving circuit and the cathode, thereby reducing the driving voltage of the driving power source and reducing the power consumption of the CRT driving apparatus.
