color tuning in the visible light range is achieved in organic light emitting transistors, using a fine tuning of the optical cavity. Remarkably, layer thickness variation, which is responsible for color tuning, does not affect the optical turn-on voltages, in contrast to organic light emitting diode devices. Significantly enhanced external quantum efficiencies are also observed for thick emissive layer devices. Optical simulations that accurately match experimental results indicate that the wide range of color tunability is mainly due to an outcoupling effect through the Fabry–Perot cavity. Our study presents a simpler and more flexible alternative for display technology design.Read less <
