An ordered and controlled microarray of isolated organic electroluminescent pixels (see Figure) is fabricated by a surface‐tension‐driven technique. The technique combines the instability of liquids, following dewetting phenomena, with geometrical confinement, induced by a template mesh, to deposit optically active molecules in an ordered fashion. The flexibility, ease of realization, and absence of any damaging lithographic step makes this a promising technique for future OLED fabrication.
