Abstract

Patterning organic materials by photolithography enables not only high-resolution, side-by-side RGB OLED arrays, but also the introduction of organic photodetector in the same frontplane. We show patterned active matrix displays processed on flexible backplane. Furthermore, we demonstrate OPD patterning proof-of-concept. These are the building blocks allowing in-cell optical fingerprint sensor.

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).
