Title: Driving circuit for organic thin film EL elements

Abstract: A pulse generator 1 creates a pulse in synchronization with a driving pulse 26. A charging circuit 2 charges EL elements 20 only for a period which is determined by an output from the pulse generator 1. The charging time is determined by resistance of a switching element 3 in its on condition and a junction capacity of the EL elements 20.
