The reflection color dispersion phenomenon is more visible on a polarizer-free OLED panel compared to a panel with a polarizer. However, the mechanism and detailed analysis of this effect is very limited in previous reports. The panel reflection patterns are usually very sophisticated, composed of rings, dots, and color distribution (RGB reflection located at different directions of the panel). In this paper, the causes of the reflection pattern are analyzed in detail and the influential factors of the shape, distribution, color, and other characteristics of the reflection pattern are clarified and verified through the comparison of simulation and actual results. Finally, ideas for improving reflection pattern are proposed.

The authors demonstrate the compensation of device-to-device variation in threshold voltage using programmable ferroelectric indium-gallium-zinc-oxide thin-film transistors. Furthermore, degradation-induced threshold voltage shift can be mitigated by programming, setting the characteristics back to their pristine state. This can be a promising alternative for the replacement of complex VT compensation circuits in display applications.
