US 6,335,713 B1 · Drive apparatus which detects spatial charge voltage on charge storage light-emitting device and controls voltage and current based on the detection while drive current is blocked

Abstract

A drive apparatus for a charge storage light-emitting device which comprises drive-voltage applying means for applying a drive voltage to the charge storage light-emitting device, drive-current limiting means for limiting a drive current to be supplied to the charge storage light-emitting device, voltage detection means for detecting a terminal voltage between both electrode terminals of the charge storage light-emitting device, and voltage control means for controlling a value of the drive voltage in accordance with the detection result as a spatial charge voltage from the voltage detection means.
