Visionox Teams up with Tsinghua University to Make a Breakthrough on OLED

According to a report from China Daily, the mainland's first company Visionox which manufactures OLED panels and Tsinghua University have jointly made up a research team to develop a proprietary technology to prolong the life time of OLED.

Zhou Shaohua, intellectual property manager at Visionox, disclosed that the company has developed "a new structure that is key to our patented OLED technology". "The invention obtains single color emission through a composite light emitting layer that prolongs the operational life of OLEDs by 20 times," Zhou said.

Current commercially produced high-definition screens have a luminance ranging from 450 to about 1,000 cdm. However, though now used in small displays on cellphones and other devices, experiments show the technology provides a lifespan of up to 100,000 hours at a brightness of 1,000 cdm, one of the best records in the global industry.

It’s said that Visionox has cooperated with Tsinghua University to set up the first domestic OLED mass production line, which began operation in 2008 in Kunshan, Jiangsu province. The effort has also resulted in more than 250 patent applications.
 
They have also participated in formulating international and national OLED standards, Zhou noted.
According to Zhou, their products have been applied in cellphones, MP3, MP4, audio and other small devices. In Addition, the technology was also used in extravehicular spacesuits worn by astronauts on the Shenzhou 7 spaceship.

Despite Visionox's OLED shipments rank among the top five in the world, it is not content with only production scale expansion, Zhou noted that their new goal now is to apply the OLED technology to large-sized devices such as monitors and color TV sets." The department manager said "We also make efforts in flexible displays and lighting applications."
