Busan National University develops a more economical solution for OLED panels

Recently, Busan National University in South Korea has made a major breakthrough in mass production of organic light-emitting diode (OLED) panels and developed a more economical and excellent solution-processed solution.

Currently, OLED panels mainly adopt multilayer vacuum deposition (VAC) solutions, while solution processed simplified structure OLEDs have the advantages of low cost and mass production. OLED panels currently also have solution coating (SOL) solutions, but there are currently many challenges in mixing adjacent organic layers.

Busan National University in South Korea has made breakthrough progress in solution processing solutions. Researchers have developed a new type of thermally cross-linked polyiminoarylpoly, which is a solvent-resistant hole injection layer material with excellent film forming properties, the most Canon level and high mobility make it possible to mass produce OLED panels.
