1. A method of fabricating an alternating current thin film electroluminescent display panel comprising the steps of:
- depositing a dielectric layer on a transparent substrate having a transparent electrode;
depositing a host layer on said dielectric layer;
ion implanting dopants into said host layer at a selected location to provide an electroluminescent at said location;
annealing the ion-implanted host layer;
depositing a second dielectric layer on said ion-implanted host layer; and
forming a backside electrode on said second dielectric layer opposite said selected location.

Abstract
A thin film electroluminescent display panel is fabricated by using ion implantation at selected locations in a host layer. By this method, strips of electroluminescent material with different dopants can be created, and these different stripes can be addressed by separate electrodes in order to obtain a multicolor display panel.
