Another possible breakthrough for LCD TVs? Researchers at Japanese chemical company Teijin and Yamaguchi University claim they have developed a new technology that makes it possible to halve the weight of LCD TVs. Conventional LCD displays are based on silicon solid-state devices on glass substrates, which “sandwich” liquid crystals. These devices generate heat when used, forcing manufacturers to go for heat-resistant (heavy) glass substrates.

But according to the researchers, they placed a thin layer of heat-resistant silicon dioxide on plastic (polycarbonate, to be more exact) instead. The plastic is lighter than glass substrates, which need solid frames to make them more stable. Plastic substrate frames are considerably lighter, with Teijin saying this will pave the way for LCD TVs that weigh 50% as much as normal.

The company also claims their production method will lead to clearer images (using plastic substrates makes it possible to build higher-power solid-state devices into the TVs). Teijin plans to enter a joint venture with a major electronics makes and commercialize their technology within the next three years.
