Ecologically sustainable and green technologies are the most highlighted subjects that influence life style and global economic growth. New generation optoelectronic devices such light emitting diode (LEDs) promote excellent energy-efficiency and lower consumption of resources that finally yield lower green gas emissions. The LED is applicable in energy-saving lighting for buildings and automotives, backlight illumination with high color rendering indeks (CRI) for flat panel displays, water and air purification system, advertisment display board, indicator in general electronic equipments, etc. By 2020, LED’s global market value is to reach USD 87 million.
Next generation solid state lighting (SSL) will take advantage of emerging technologies: GaN-on-GaN LED, laser based lighting, and high brightness organic light emitting diodes (OLEDs). New materials are crucial in driving down the price tag and driving up market acceptance. SSL-LED industry is one of the most promising and upcoming market in the electronics industry.
To cater for this business, there is a pertinent need to develop our technology and human capital to be more technologically competent with the objective to become strategic key players as needed by the industry. The developement of front end technology (epitaxy) is critically needed as epitaxy suppliers control the market and create more competitive downstream players.
The objectives of this program are to develop the human capital, and perform exploratory research for the next generation solid state lighting technology based on GaN-on-GaN LED, OLED, and novel LED devices.
- GaN-on-GaN LED epitaxy and development of bulk GaN will enable Malaysia to be at the fore front of a new technology which will revolutionize the current technology base on GaN on sapphire.
- OLED technology will enable more players from industries in Malaysia to be at the front end manufacturing for development of lower cost SSL applications.
- Novel LED structures utilize nanostructures for low cost, and energy efficient next generation optoelectronics.
