Abstract
The reflection color dispersion phenomenon is more visible on polarizer‐free OLED panel compared to the panel with polarizer. However, the mechanism and detailed analysis of this effect is very limited in previous reports. The panel reflection patterns are usually very sophisticated, which are composed of rings, dots and color distribution (R G B reflection located at different direction of the panel, respectively). 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.
