Abstract
A full-color active matrix organic light-emitting color display panel is disclosed which has an integrated shadow mask structure for patterning arrays of color subpixels. The in-situ shadow mask structure is prepatterned on the display substrate by conventional photolithography, and provides a simple, self-alignment feature for successive deposition of color organic electroluminescent (EL) media on designated color subpixel areas. The pillar structure of the shadow mask are particularly effective in the fabrication of high-resolution full-color organic light-emitting diode displays having either color conversion layers or individual red, green, and blue emissive layers.
