Eliminate angular color shift in top-emitting OLEDs through cavity design
JOURNAL OF THE SOCIETY FOR INFORMATION DISPLAY, 27(8), 469–479.
Abstract OLEDs suffer from viewing angle dependent spectral shift due to microcavity effects. To address this issue, we introduce a novel top‐emitting OLED with a dielectric spacer that forms multiple cavity modes. The resulting device shows almost no color shift at different viewing angles.
