2020 journal article

Multi-mode Organic Light-Emitting Diode to Suppress the Viewing Angle Dependence

ACS APPLIED MATERIALS & INTERFACES, 12(28), 31667–31676.

By: C. Dong n, X. Fu, L. Cao*, S. Amoah n, K. Gundogdu n , J. Li *, F. So n 

author keywords: white OLED; top-emitting OLED; cavity effect; multiple cavity modes; angular color shift
TL;DR: A multi-mode OLED structure having dual-dielectric spacer layers, which completely eliminates the intrinsic cavity effect caused by the top and bottom boundaries respectively and provides freedom for the organic layer thickness. (via Semantic Scholar)

2020 journal article

Recovering cavity effects in corrugated organic light emitting diodes

OPTICS EXPRESS, 28(21), 32214–32225.

By: X. Fu, Y. Chen*, D. Shin n, Y. Mehta n, I. Chen*, N. Barange n, L. Zhu n , S. Amoah n, C. Chang*, F. So n 

TL;DR: It is found that the cavity effects can be partially recovered using a low index Teflon layer inserted between the ITO anode and the substrate due to the enhancement of the reflectance of the corrugated electrodes. (via Semantic Scholar)
