Abstract
In this paper, we propose an ultrahigh-resolution organic lightemitting diodes (OLEDs) pixels patterned by conventional photolithography through by incorporating silicone into phosphorescent small-molecule networks. This siliconeintegrated phosphorescent organic light-emitting diode (SIphOLED), in which silicone molecules are homogeneously crosslinked with small-molecule light-emitting materials, can effortlessly achieve to 3,000 PPI ultrahigh-resolution patterns using the photolithography process.
