Abstract

PURPOSE: To make the display of a TV video signal possible by using a matrix thin-film EL display unit of a double insulation type.
CONSTITUTION: Electrodes are formed crossing mutually at right angles on both surfaces, of thin film dielectric layers provided to both sides of a thin film EL layer, in a matrix, thereby forming double insulation type matrix thin-film EL display unit 10. By using this display unit, video signals are stored during one horizontal scanning period of the TV signal corresponding to respective horizontal scanning electrodes and at the same time, auxiliary charging to the thin film EL element is done. At the time of a horizontal synchronizing signal, the charge amount through the previous auxiliary charging is controlled by a constant-current dischaege circuit composed of a constant-current element with a memory signal; and a write voltage is applied to the thin film EL element at the front side of the next horizontal scanning interval and the auxiliary charging is repeated at the back side of the horizontal acanning interval. Consequently, TV pictures can be displayed
