and will continue to do so for many years to come,” concludes Demir.
Demir is a faculty member of the Division of Microelectronics at the School of Electrical & Electronic Engineering and Division of Physics and Applied Physics at School of Physical and Mathematical Sciences. He is a recipient of many prestigious awards including Singapore National Research Foundation (NRF) Fellowship, the European Science Foundation European Young Investigator Award (EURYI), and the Marie Curie Intra-European Fellowship; he completed his PhD at Stanford University, USA.
Luminous! Center of Excellence for Semiconductor Lighting and Displays is focused on various multidisciplinary studies to offer solutions addressing energy efficiency and photometric quality problems in lighting, including the Super- Excitonics Program funded by NRF Competitive Research Program. Luminous! pursues an integrated approach including materials research, device physics, and applications. The MOCVD facility is dedicated to SSL and displays by developing a new class of solid state lighting white LEDs integrated with semiconductor nanophosphors.
*Mesopic vision, the combination of photopic and scotopic vision for low but not completely dark lighting situations, covering light levels with luminances over 0.001 to 3 cd m-2 which includes the majority of night-time outdoor and traffic lighting scenarios.
LED-TV explosion creates a boom in the LED market
According to “The Global and China LED Industry Report, 2010-2011”, since Veeco launched the K465I in the Chinese market, its revenue soared 230%, putting a great deal of pressure on Aixtron.
The report, available from
reportlinker.com, says the LED market size climbed 58% to US$15.8 billion in 2010 from US$10 billion.
The market size of LED for LCD TV backlight actually boomed to approximately US$3.9 billion from US$960 million driven by the explosion of

The market share of LED-backlit LCD TV arrived at 26.9% in 2010, and it is predicted to see 55.9% in 2011. Promisingly, LED will completely replace CCFL in 2014. The market share of LED-backlit NB rose to 95% in 2010 from the merely 59% in 2009; while that of LED-backlit LCD hit 15% in 2010 from 1.5% in 2009, and is projected to rest on 40% in 2012.
The global LED industry can be divided into four big regions elaborated as follows:
1. The European & American region that focuses on general lighting and gives priority to the high reliability and high brightness of products;
2. Japan which boasts the most comprehensive technology and the most powerful strength in both general lighting and backlight display, with the development orientation attaching equal importance to general lighting, automotive, mobile phone, and TV;
3. South Korea and Taiwan that highlight the laptop display backlight, LED-TV backlight, and mobile phone backlight, featuring large shipment, low unit price, and meagre gross profit;
4. Chinese Mainland which gives priority to yellow- green LED and aims at outdoor display, advertising screen, and signal lamp. The applications require low product technology and reliability, the clients are scattered and of small scales, yet the gross profit is not low due to the engineering projects in most cases.
The Chinese Mainland is at best a production workshop although it has manufactured 80% mobile phones, 95% notebook computers, 50% LCD TVs, and 95% LCDs worldwide. As a whole, the key raw materials, small & medium-sized panels, and large- sized panels are monopolized by Japanese, South Korean, and Taiwanese enterprises.
European & American enterprises have nothing to do with the flourishing LED backlight market in that they have targeted at the big market of general lighting from the very beginning. In 2010, the shipment expanded greatly, but the price dropped dramatically, which just brought along slight growth to these manufacturers. Japanese, South Korean,
