Abstract
This invention describes fabrication techniques for producing microdisplays suitable for combining into tiled, flat-panel displays having visually imperceptible seams. Assembly techniques to overcome flatness requirements imposed by tiled, flat-panel display assemblies are also described. Edge treatment techniques for individual microdisplays while still part of the silicon die or wafer are also described. The use of these inventive techniques allows the assembly microdisplays into tiled, flat-panel that are appear visually seamless and optically uniform.
