ABSTRACT:
An electronic display 10 such as a flat panel display device includes spacing layers 70-88 operatively disposed around the display pixels. The spacing elements are formed by depositing a material, such as a carbon material, and selectively etching back the layer to pre-selected areas. This has the advantage of precisely placing the spacers where support is necessary, while avoiding problems with misplacement of spacers and the resulting loss of manufacturing yield.
