Abstract: Circuit arrangement for a picture display device for the stabilization of the size of the picture displayed.In picture display devices having cathode-ray tubes, the first anode voltage for these tubes is recovered from the retrace pulse at a corresponding winding of the line transformer, this anode voltage source being of a relatively high ohmic value. As a result thereof, the anode voltage decreases versus an increasing anode current, and consequently, the picture displayed on the display screen becomes larger. More specifically, for picture display devices for word processing, which have a positive display, a very different anode current can flow because of different brightness settings. So as to produce nevertheless a largely constant anode voltage, a circuit arrangement which behaves as a negative resistance is provided at the lower end of the high-voltage winding.
