Title: Solution-Processed Organic LEDs
Abstract:
Organic light-emitting diodes (OLEDs) have many promising applications in active matrix displays, solid-state lighting, visible light communication, and medical treatment. Currently, the manufacturing of OLEDs highly relies on high-vacuum thermal evaporation, which is highly expensive and complicated. To address this issue, solution-processed OLEDs are more favorable due to the merits of large-area and low-cost mass production. In this talk, the soluble emitters featuring charge transfer characteristics and high efficiency will be showcased. Moreover, the state-of-the-art solution-processed OLEDs, via spin-coating, inkjet printing, and transfer printing, respectively, will be elaborated, including material design and device engineering. In addition, the fundamental photophysics and device physics of the solution-processed OLEDs with high exciton utilization efficiency will be explained.
