Abstract

정정 회로내에서 구동 신호, 특히 소자의 변화(스위치(35)의 눈에 띄는 노화)를 알리는 피드백 라인(39)상의 열신호의 영향은 제거된다. 본 목적을 위해 인입(비디오) 신호(42)의 일부는 피드백 라인(39)으로부터의 신호와 섞인다.In the correction circuit, the influence of the drive signal, in particular the thermal signal on the feedback line 39 informing the change of the element (noticeable aging of the switch 35) is eliminated. A portion of the incoming (video) signal 42 is mixed with the signal from the feedback line 39 for this purpose.
