    摘要： The life time of a CRT is extended by decreasing the temperature of the cathode by 7-30% from the normal operating temperature and by applying a constant voltage signal to a cathode of the CRT which is shifted from a first voltage level for displaying the lowest luminance of the image toward a second voltage level for displaying the highest luminance of the image. The shift is of the order of 5-25%, so that a constant anode current in the range of 2-14 uA flows in the CRT.

    摘要： The objects of the present invention are achieved by forming a high voltage generating circuit which comprises: a flyback transformer having a primary winding and a secondary winding; means for supplying pulses of first frequency to the primary winding; a smoothing capacitor connected across the secondary winding; an output line connected to one terminal of the smoothing capacitor; means for detecting a variation of high voltage on the output line to generate compensating voltage pulses of a second frequency which is higher than the first frequency for compensating the variation of high voltage to supply the compensating voltage pulses to the other terminal of the smoothing capacitor. Additionally, a low pass filter is connected between the other terminal of the smoothing capacitor and the secondary winding, which prevents the compensating voltage pulses from being supplied to the secondary winding. Further, a capacitor is connected between the other terminal of the smoothing capacitor and a reference potential. Moreover, the first frequency is equal to a horizontal deflection frequency of a cathode ray tube, and the second frequency is N times as large as the first frequency, wherein N is integer larger than 1. The first frequency could also be 1/N times as small as a horizontal deflection frequency, wherein N is integer larger than 1, and the second frequency is equal to the horizontal deflection frequency. Finally, the output line is connected to an anode of a cathode ray tube.
