A man walks through the desert leaving footsteps where green light emits from. J.‐J. Kim and co‐workers demonstrate on page 5684 such high EQEs achieved with a green fluorescent OLED where phosphorescent OLEDs have been considered to be very dominant. The authors address the challenging concept of taking advantage of an exciplex‐forming host doped with a fluorescent dye.
