Green technology in flat panel displays<br />
David Hsieh is vice president of the Greater China Mark<strong>et</strong> for <strong>Display</strong>Search. David<br />
joined <strong>Display</strong>Search from HannStar <strong>Display</strong> where he was a key account manager<br />
responsible for both notebook and LCD monitor accounts. Prior to two years in<br />
HannStar's sales and mark<strong>et</strong>ing department, Hsieh served for a total of five years as<br />
production planner and production engineer at HannStar's TFT LCD module line and<br />
Hitachi Kaohsiung's STN LCD module line. Hsieh is fluent in Taiwanese, Mandarin,<br />
Japanese, and English and holds a degree in Industrial Engineering from Chung-Yuan<br />
Christian University.<br />

With “green” becoming an increasingly important concept in many flat panel display<br />
applications and the evolution of technologies to enable green displays, it’s no surprise<br />
that green flat panels are beginning to take off and will become the most important trend in the FPD industry for the<br />
next decade. <strong>Display</strong>Search reports that in 2008 20% of FPD shipments were green, and this share is expected to<br />
soar to 70% by 2012 and dominate the mark<strong>et</strong> by 2014. <strong>Display</strong>Search has created a new topical report dedicated to<br />
Green FPD – Green Technology in Flat Panel <strong>Display</strong>s: Mark<strong>et</strong> Technology & Trends – which examines<br />
environmental regulations, power-saving technologies, eco-friendly components, energy-saving manufacturing<br />
processes, and panel structure simplification efforts of the main three kinds of FPD, TFT LCD, OLED and plasma.<br />
<strong>Display</strong>Search defines green flat panel displays as those which me<strong>et</strong> one of the following conditions: using<br />
environmentally friendly components and materials; achieving lower power consumption by using new components<br />
or technologies; compliant with environmental regulations such as waste disposal; using production processes that<br />
reduce energy and materials consumed; compl<strong>et</strong>ely or partially recyclable after useful life; or use of green or ecofriendly<br />
concepts in product design, packaging m<strong>et</strong>hods or materials. David Hsieh, vice president of <strong>Display</strong>Search<br />
and the author of the report, specifically uses a chart, shown as Figure 1, to describe the green perspectives in the<br />
flat panel display industry.<br />
