Korean boffins come up with affordable OLED tech

Solvent-resistant hole injection layer material synthesised 

Boffins at the chemistry department at Pusan National University, Korea, have come up with a process which could make OLED TV production much cheaper.

The researchers were able to synthesise a solvent-resistant hole injection layer material used in the OLED stack and “achieved a greater efficiency and lifetime.”

With the new solution, OLEDs promise “an economical, large-scale fabrication technique” and could be made more cheaply and efficiently, and at a greater scale. OLED TV prices could fall and start giving QLED TVs a run for their money. 

A major reason why OLED TVs are pricier than their QLED counterparts is that OLED TV production, which uses a process called vacuum thermal evaporation, is both expensive and labor-intensive. An alternative to current production methods is solution-processed OLEDs, but so far the use of that technique has been limited due to the difficulty in “stacking” the component layers used in OLED panels.
