Micro organic light-emitting diodes fabricated through area-selective growth

Abstract

Developments in micro-displays have led to great interest in patterning OLEDs on the microscale. However, because organic molecules are fragile in adverse environments, patterning OLEDs on the microscale remains underdeveloped. In this work, the fabrication of Micro-OLEDs via the area-selective growth of hole-transporting material is reported. The active material is selectively deposited on pre-determined areas, and this technique is compatible with photolithography. High-resolution OLEDs with feature sizes as low as sub-micrometer and green-, orange-red- and deep-blue-emitting devices are demonstrated. This technique provides a promising method for the fabrication of high-resolution OLED devices over large areas.
