Circuit de commande, appareil d'affichage utilisant ce circuit de commande, et méthode d'évaluation du circuit de commande

Drive circuit, display apparatus using drive circuit, and evaluation method of drive circuit

Abstract

For making outputs of a drive circuits accurate, the drive circuit is composed of a plurality of current signal generation circuits for outputting a current signal to each of a plurality of output units, a current signal output line to which outputs of the plurality of current signal generation circuits are commonly connected, a correction value output circuit for outputting a correction value obtained by evaluating the output of a specific one of the plurality of current signal generation circuits on a basis of current values output through the current signal output line, and a correction circuit for correcting an image signal supplied to the current signal generation circuits by means of the correction value.
