P‐150: High Temperature High Performance Top Emitting Yellow OLED

Efficient top-emitting phosphorescent yellow OLED micro-displays were developed on active matrix single crystal silicon. Very stable 1931-CIE coordinates across a wide range of current density were achieved in single emission zone devices with efficiencies ∼55 cd/A, 18% EQE relative to dual emission zone devices. Device lifetimes were measured.
