Recycling-friendly LCD glass substrate

Thursday, 23 March, 2006

The proliferation of home entertainment systems has raised a number of issues, especially concerning the shelf life of LCDs and the impact of their disposal on the environment.

Technology developer, Corning has launched Eagle XG, what it claims is the industry's first liquid crystal display (LCD) glass substrate that is free of all heavy metals.

"Corning continues to create value through the minimisation of potential costs related to environmental regulations and recycling challenges," said James P. Clappin, president, Display Technologies.

"Eagle XG is a green substrate that provides value for panel manufacturers, and the entire TFT-LCD value chain, while retaining all of the process benefits and attributes of EAGLE2000, a glass composition from Corning," Clappin continued. "Eagle XG is an environmentally friendly glass that is the first of its kind. The value it provides to our customers will continue to increase as future environmental regulations are introduced."

The LCD glass is free of heavy metals, including arsenic. As with EAGLE2000, it is also free of antimony and barium, and halides such as chlorine and fluorine. These materials, added by some glass suppliers during their manufacturing process, can produce potentially harmful manufacturing by-products.
