Abstract

PURPOSE: To avoid the luminance unevenness, by reducing the amplutude of keep pulse and the dispersion in transient time constant, through the supply of keep voltage to each electrode of thin film EL elements via diodes.
CONSTITUTION: Between the keep voltage +Vs and -Vs and the output terminal Yj to apply the voltage to the thin film EL element, transistors R1 and R4 and diodes D1J to D4J are connected. With this constitution, the potential of the output terminal Yj is made to the level of the keep voltage +Vs with the transistor R1 and is made to 0 level with R2. Further, it is possible to take-Vs level with the transistor R3 and ground potential with R4. On the other hand, erase pulse and write-in selectin pulse are fed with the transistors Q1j and Q2j connected to the voltage +Vs and-Vs, and at this time, the diode group performs to seprate the scanning lines of non-selection. Thus, power consumption can be reduced
