Abstract
High-resolution RGB organic light-emitting diode frontplane is a key enabler for direct-view transparent augmented reality displays. In this paper, we demonstrate 1250 ppi passive displays and semi-transparent active displays. Organic light-emitting diode photolithography can provide pixel density above 1000 ppi while keeping effective emission area high because of high aperture ratio. Patterns with 2 μm line pitch were successfully transferred to emission layers, indicating possible further pixel density scaling. Lifetime after patterning, key parameter enabling industrialization, is above 150 h (T90 at 1000 nit).
