微型显示器的发展引起了人们对微型 OLED 图案化的极大兴趣。然而，由于有机分子在恶劣环境下很脆弱，因此微尺度的图案化 OLED 仍然不发达。在这项工作中，报道了通过空穴传输材料的区域选择性生长来制造 Micro-OLED。活性材料选择性地沉积在预定区域，并且该技术与光刻兼容。展示了特征尺寸低至亚微米的高分辨率 OLED 以及绿光、橙红和深蓝光发射器件。该技术为大面积高分辨率 OLED 器件的制造提供了一种有前景的方法。
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.
