Abstract

In this paper, we propose an ultrahigh‐resolution organic light‐emitting diodes (OLEDs) pixels patterned by conventional photolithography through by incorporating silicone into phosphorescent small‐molecule networks. This silicone‐integrated phosphorescent organic light‐emitting diode (SI‐phOLED), 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.
