GE and KM Closer to Developing High-Efficient OLED Lighting Devices

Scientists from Konica Minolta (KM) and GE Global Research have achieved a significant breakthrough that would enable the production of high-efficient OLED (organic light-emitting diode) lighting systems. The scientists showed that white OLEDs can be produced cost-effectively by utilizing solution-coatable materials.

Pioneer of GE’s OLED lighting technology, Anil Duggal, announced the major breakthrough at the International Symposium on the Science and Technology of Light Sources. The conference was held in Netherlands.

Both KM and GE have planned to produce OLED lighting devices by utilizing advanced roll-to-roll processes instead of the usual vacuum-based batch techniques adopted by OLED manufacturing companies. The roll-to-roll process is vital for manufacturing commercially-viable OLED products for common lighting applications. Wet coating provides an efficient production technique for coating the organic layers, which are the essential components of the OLED devices.

GE Lighting’s General Manager, John Strainic, informed that the solution coating is suitable for roll-to-roll processing and can speed up the production of OLED lighting devices.
