Query: Solution Processability and Thermally Activated Delayed Fluorescence:
  Two Steps towards Low-Cost Organic Light Emitting Diodes   Organic Light Emitting Diodes (OLED) have experienced vast attention in the
scientific literature as the leading contender for the next generation of
electronic lighting technology. However, while research continues to push the
limit for OLED performance and efficiencies, minimal attention is paid to the
processability and suitability for mass production. In this regard, Solution
Processability (SP) and Thermally Activated Delayed Fluorescence (TADF) in
OLEDs are two recent discoveries which have significantly improved the capacity
for low-cost processing without compromise to their performance efficiencies.
This meta-analysis is focused on these discoveries and their application to
OLEDs. Recent peer-reviewed studies of OLEDs employing both SP and TADF are
reviewed in order to highlight physical fundamentals and discover synergistic
effects when incorporating both factors into a single OLED device.
Additionally, some other recent trends targeting efficient manufacturing of
OLEDs are identified, and logical future directions for interested researchers
are discussed.
