OLED will replace LCD into the mainstream

The Hong Kong University Science & Technology invited, "OLED" the father of the United States, Rochester College professor Deng Qingyun on the 8 day port lectures, analysis technology breakthrough development, also interspersed lived in Hong Kong for years, recalling the past, miss lee.

OLED, organic light-emitting diodes, is a base for organic thin film has light source of display technology.And at present the mainstream LCD screen (LCD), OLED screen can slim (the thin a few tenths of a millimeter), ultra light, flexible, high resolution, low energy consumption, wide viewing angle characteristics.

So advanced, OLED less than LCD popularity?"Technology has matured, but the material, equipment still exist some problem, be the undoing of the LCD barrier."Deng Qingyun said, the first is the life, the original OLED screen shows only a few minutes, now up to a maximum of 1000000 hours, but the deep blue OLED light-emitting efficiency is still low; and the production cost is high, the cost is high screen.

But Deng Qingyun believes that the prospect of OLED is beyond question, "the next 5 to 10 years, longer life, lower cost, higher megapixel, can show the 3D effect of AMOLED (active matrix organic light emitting diode), is expected to replace the LCD's leading position".He refers to, a South Korean electronics manufacturers have announced investment of more than $600000000 to build the OLED production line.

In fact, Deng Qingyun in the 20 years before the invention of the first small molecule OLED.Early dating back to one night in 1979, because of forgetting things and reentrant laboratory he found a piece of organic battery in luminescence, which launched on the "electric light" decades of inquiry.With around OLED research, Deng Qingyun award-winning, including in 2011 to become the first Chinese winners of the Wolf prize in chemistry.

According to statistics, more than 1/3 of the Wolf prize for physics and chemistry prize winner is awarded Nuobeire award."Said Professor Dumbledore has a 1/3 chance to again won the Nobel prize."The same study OLED university professor Guo Chenghai, called Deng Qingyun "the lights of Hongkong".

"This is the village where I was born, then there are no electricity!"Deng Qingyun points to New Territories, a corner, laughing himself as "the country's" change "scientists".He also shows a photograph -- comb the traditional bun two woman with a brown hair foreign woman side stands, turned out to be his grandmother, mother and wife."My grandmother taught me to be generous, mother taught me patience."
