Abstract

A method of making a tiled emissive display having at least two aligned tiles including finishing at least one edge of each tile and aligning the finished edges of such tiles and forming a monolithic structure including aligned tiles, each such aligned tile having a substrate, TFT circuits, drive circuits and bottom pixel electrodes for providing electrical signals to pixels in the corresponding tile. The method also includes coating the aligned tiles with material that produces light when activated by an electric field and forming at least one top pixel electrode over the coated material so that the coated material produces light when activated by an electric field from the electrode.
