We studied efficient light emission from printed small molecular electrophosphorescent OLEDs (PHOLEDs). The organic layer was made by ink‐jetting with a composite solution, prepared by dissolving small molecular compounds into mixed solvents. Efficient green light emissions were generated at relatively low voltages; the peak luminance over ∼50,000 cd/m 2 with the peak current efficiency of 45 cd/A.
