Abstract (en)
[origin: WO9616392A1] Correction circuit in which the influence of drive signals, particularly column signals on feedback lines (39) signalling changes in elements (notably ageing of switches (35)) is eliminated. To this end, a fraction of the incoming (video) signal (42) is mixed with the signal from the feedback line (39).
