DRIVING APPARATUS, DISPLAY DRIVER AND ELECTRONIC APPARATUS

摘要

The driving device used for drive control of a driven device having driven elements arranged to commonly receive a common voltage at common terminals and individually receive drive signals at data terminals has: a drive voltage-producing circuit which produces drive voltages; a driver circuit which accepts input of the drive voltages produced by the drive voltage-producing circuit and outputs, as drive signals, signals selected from the drive voltages according to drive data from data output terminals in parallel; and a common voltage-producing circuit which produces a common voltage to output from a common-voltage-output terminal. In the driving device, the drive voltage-producing circuit detects a change in the common voltage output from the common-voltage-output terminal, and changes the drive voltages in the direction of the change.
