Abstract:
A method of fabricating a multi-color flat panel display, comprising:forming a first sacrificial layer on the substrate; providing a plurality of first openings in the first sacrificial layer to the substrate; depositing a first semiconductor phosphor material on the substrate to cover the first sacrificial layer and the substrate through the plurality of first openings; removing the first sacrificial layer and the first semiconductor phosphor material covering the first sacrificial layer to leave a plurality of first active elements of the first semiconductor phosphor material on the substrate at positions corresponding to the plurality of first openings; forming a second sacrificial layer on the substrate and the plurality of first active elements; providing a plurality of second openings in the second sacrificial layer to the substrate, each of the plurality of second openings being adjacent to a corresponding one of the plurality of first active elements; depositing a second semiconductor phosphor material on the substrate to cover the second sacrificial layer and the substrate through the plurality of second openings; removing the second sacrificial layer and the second semiconductor phosphor material covering the second sacrificial layer to leave a plurality of second active elements of the second semiconductor phosphor material on the substrate at positions corresponding to the plurality of second openings; and depositing transparent electrodes on the plurality of first active elements and the plurality of second active elements.
