Within these approaches, the most effective one is the green component usage. On the glass substrate side,<br />
Corning’s EAGLE XG performs the same features as the previous product, the EAGLE 2000. EAGLE XG glass is<br />
recognized as green glass, because it has no halide elements or other heavy m<strong>et</strong>al elements and it does not include<br />
hazardous elements such as arsenic, antimony or barium.<br />
The reduction of lamps and driver ICs keeps up its steady momentum in monitors and LCD TVs. For example, the<br />
32-inch panel is aggressively moving toward the use of U lamps to replace the conventional CCFL and to reduce<br />
the number and power consumption of lamps and inverters. As shown in Figure 3, the 32-inch LCD TV backlight<br />
unit structure evolution is a perfect example of how the panel makers reduce the number of CCFL units but achieve<br />
the same brightness through the functionalities of the optical films.<br />
