In 2008, 20 percent of flat-panel display (FPD) shipments had green features, and this share is expected to soar to 70 percent by 2012 and dominate the market by 2014, according to DisplaySearch.

DisplaySearch's report called "Green Technology in Flat Panel Display: Market Technology and Trends" examined the environmental regulations, power-saving technologies, eco-friendly components, energy-saving manufacturing processes, and panel structure simplification efforts of the main three kinds of FPD: TFT LCD, OLED and plasma.

The report defines green FPDs as those meeting one of the following conditions: using environmentally friendly components and materials; achieving lower power consumption by using new components or technologies; compliant with environmental regulations such as waste disposal; using production processes that reduce energy and materials consumed; completely or partially recyclable after useful life; or use of green or eco-friendly concepts in product design, packaging methods or materials.

Why go green?
DisplaySearch finds that FPD supply chain participants work on green FPD for many reasons: environmental regulations, like RoHS, WEEE, Energy Using Products (EuP), Energy Star, TCO and others; cost reduction (While not all green FPD technologies represent cost reductions for panel makers, as long as the technologies improve and more suppliers adopt them, green will eventually lead to lower costs.); social responsibility, such as corporate citizenship in areas including global energy savings; and prevention of future damages or customers claims.

As the figure below shows, 2008 was the year of green FPD development, with green panels accounting for nearly 20 percent of the total $95.6 billion market for TFT LCD, OLED and plasma displays. DisplaySearch defines 2009 as the year of green implementation, and panels and end products will be focusing on green promotion in 2010. Green FPD penetration will pass 50 percent in 2011 and then achieve 100 percent in 2014.

"Energy savings is a hot topic globally, whether the economy is good or bad. Displays often have the highest power consumption of any component in electronics products," said David Hsieh, vice president of DisplaySearch and the author of the report.

Green panels accounted for nearly 20 percent of the total $95.6 billion market for TFT LCD, OLED and plasma displays in 2008.

Regarding TFT LCD, there are currently four methods to implement green displays:

??Green panel design, i.e. new cell structures that increase panel transmittance or new technologies like PSA, COA, AMVA and SHA;

??Energy-saving production processes, i.e. photomask reduction, ink-jet printing of color filters, roll-to-roll production, and replacement of toxic gases in production;

??Green components, i.e. glass, color filter, liquid crystal, optical films, driver ICs and LED backlights;

??Packaging, i.e. space-saving containers for better transportation efficiency and recyclable packing materials.

DisplaySearch defines OLED as a naturally green technology, due to the simpler structure, reduced materials consumption, and lower power consumption. For plasma, there are three ways to implement green: high luminous efficiency, eco-friendly materials with lower EMI and new manufacturing processes for materials reduction.
