OLED-Info published an interview with Fast2Light's project manager Mary M. Kilitziraki. Fast2Light is an R&D setup that researches and develops light emitting foils based on OLED technology.

Quote: "There are a few milestones to be achieved before OLED makes it to the lighting market; a very important one is the performance and lifetime of the light emitting material. When one is considering OLED lighting on foils, then next to the material, a superior thin film barrier for oxygen and moisture is a must and if one takes it one step further and considers cost, R2R processes for all layers need to be developed."
