Abstract
A picture display device in which velocity modulation of the electron beam is effected with a deflection correction signal derived from the video signal to be displayed. The brightness distribution influenced by this deflection correction signal in a sudden brightness transient is corrected by adding to the video signal a brightness correction signal which is predominantly proportional to the product of the video signal and a first derivative with respect to time of the deflection correction signal.
