Abstract
A picture display device including a generator circuit for generating a periodical waveform for addressing picture elements on a picture display screen, this generator circuit including a time-determining network with a capacitor. To reduce the influence of tolerances, the picture display device is provided with a compensation circuit including a second generator for generating a second periodical waveform and a source for applying a compensation current to the first-mentioned capacitor in dependence upon the second waveform, the second waveform generator including a time-determining network with a second capacitor and both capacitors being integrated in one semiconductor body.
