ABSTRACT: "Picture display device including a line synchronizing circuit and a line deflection circuit." A picture display device, comprising a line synchronizing circuit and a line deflection circuit, suitable for several line frequencies. For this to be the case, use is made of a modulator for modulating the line deflection current, a control stage being coupled to this modulator for applying a correction signal for correcting, in dependence on the frequency of the line oscillator, the S-distortion or the linearity error, respectively, or to keep the amplitude of the line deflection current constant upon a change in the line frequency.
