Toshiba promotes OLED light extraction efficiency by using nano grating

In the recently held international nanotechnology exhibition and seminar, Toshiba demonstrated a new technology that can significantly enhance the efficiency of light extraction OLED TV and lighting equipment.

"OLED is expected to become an important next generation display technology," said Toshiba in a statement".

This new technology is composed of hundreds of nanometer sized nano gratings on SiO2 substrate. In a comparative experiment, Toshiba uses nano grating technology to improve the efficiency of OLED devices by 60%.

In order to improve the light extraction efficiency of OLED devices, the diffraction grating is used in Toshiba, and a kind of technology called sELf-assembly nanoengineering self-assembly nano engine is adopted.

Toshiba said that this technology is still in the laboratory stage, there is still a considerable distance from the market.
