Abstract
A flat panel X-Y matrix display has gas discharge switches which are disposed in capacitive series contact with associated electroluminescent cells. The gas discharge switches are selectively ionized to continuously energize and light the EL cells until the switches are turned off. The switches thus provide an active energization matrix for the cells.
