Abstract:
(EN) To provide a novel semiconductor device or display device. The semiconductor device includes a decoder circuit, an amplifier circuit, and an arithmetic circuit. The amplifier circuit includes a first amplifier and a second amplifier. One of the first amplifier and the second amplifier has a function of inspecting an output of the other of the first amplifier and the second amplifier. The arithmetic circuit has a function of calculating an error of a potential output from the first amplifier or the second amplifier, on the basis of a result of the inspection. The decoder circuit has a function of correcting a video signal input to the decoder circuit by subtracting the error of the potential from the video signal.
(FR) L'invention concerne un nouveau dispositif à semi-conducteur ou un dispositif d'affichage. Le dispositif à semi-conducteur comprend un circuit décodeur, un circuit amplificateur et un circuit arithmétique. Un circuit amplificateur comprend un premier amplificateur et un second amplificateur. Le premier amplificateur ou le second amplificateur a pour fonction d'inspecter une sortie de l'autre amplificateur. Le circuit arithmétique présente une fonction de calcul d'une erreur d'une sortie potentielle du premier amplificateur ou du second amplificateur, sur la base d'un résultat de l'inspection. Le circuit décodeur a une fonction de correction d'une entrée de signal vidéo vers le circuit décodeur par soustraction de l'erreur du potentiel à partir du signal vidéo.
