OLED-T launches low-temperature LiF replacement
London display materials developer OLED-T has launched a low-temperature organic electron injector material for organic LED displays.
Called EI-111-2Me, it is a replacement for LiF – “the material typically used by OLED display manufactures as the electron injector layer within an OLED display,” said the firm. “EI-111-2 Me evaporates at 200°C as opposed to LiF which requires a temperature of over 600°C, making the deposition faster and more controlled and introducing the potential of using plastic as a substrate rather than glass.”
Between electrode and emissive layers, OLED displays have electron and hole injector and transport layers
In customer trials using EI-111 as a direct replacement for LiF, claims OLED-T, display efficiency improved by 25 per cent and lifetime by 10 per cent.
“As the market for OLED matures display manufacturers are focused on reducing cost throughout the display supply chain,” said OLED-T CEO Myrddin Jones. “EI-111-2Me provides companies with a significant opportunity to reduce cost at the same time as improving the performance of OLED displays.”
The material is sampling now with volume production expected from the fourth quarter of 2008.
