Lab opens up in name of energy efficiency

Local | Hilary Wong 27 Sep 2013

A new national laboratory that may enhance research into green displays was opened yesterday at the Hong Kong University of Science and Technology.

The Partner State Key Laboratory on Advanced Displays and Optoelectronics Technologies was set up in collaboration with Sun Yat-sen University, and with the approval of the Ministry of Science and Technology.

Optoelectronics is the application of electronic devices that detect and control light.

One of the laboratory's main tasks is to develop energy-efficient green displays.

Director of the Center for Display Research Kwok Hoi-sing said display technologies have a wide range of applications such as smartphones.

Research projects will concentrate on areas such as the development of a new generation of light- emitting diodes and liquid-crystal displays, said the president of HKUST, Tony Chan Fan-cheong.

This will include active organic light-emitting diodes displays.

"The LED displays we use now are energy consuming because the optical filter consumes so much," Kwok said.

The green displays to be developed, using active organic light- emitting diodes, may save up to 10 times the energy and its lifespan be prolonged.

They have better quality, higher definition of images and may be made for less.
