SELECTIVE FILLER PATTERNING BY LITHOGRAPHY FOR OLED LIGHT EXTRACTION

Abstract:

Embodiments of the present disclosure generally relate to electroluminescent (EL) devices. More specifically, embodiments described herein relate to methods for forming arrays of the EL devices and selectively patterning a filler material in the EL devices. The EL device formed from the methods described herein will have improved outcoupling efficiency because of the patterned filler. The methods described herein pattern the filler and provide large area, low cost, and high resolution EL device formation by not relying on ink-jet printing or thermal evaporation with a fine metal mask.
