AGC: Glass Substrate for LGPs that Enable Extra-Thin LCD TVs
Asahi Glass Co., Ltd. (AGC) recently announced that it is supplying manufacturers with a glass substrate for light guide plates (LGPs), named XCVTM (pronounced “ex-ive”), that helps reduce the thickness of LCD TVs and displays to about 5 mm. XCVTM, which reportedly offers high transmittance and extended flexibility for designing, has already been adopted for stylish, next-generation TVs and displays marketed by several manufacturers.
Compared to conventional LGPs made from acrylic resin, AGC’s new XCV glass substrate reportedly offers more than 20 times greater stiffness and a coefficient of thermal expansion reduced by a factor of eight. Also, the bezel (or grooved area used to hold the screen in place) can be made narrower because XCV is highly resistant to thermal expansion, enabling more stylish product designs. In addition, XCV does not require structural components needed to support plastic LGPs, so it helps to reduce display weight.
By adopting its proprietary extra-efficient float process developed for the production large glass substrate, AGC is prepared to mass-produce and quickly deliver XCV to meet strong demands from TV and display manufacturers. LGPs use the edge-lit method to transmit and diffuse light from LEDs placed at the screen’s edges, resulting in improved backlighting of the screen. Whereas existing glass materials are not suited to LGPs due to their low transmittance, XCVTM offers the necessary high transmittance to assure extra-bright displays.
“AGC developed its new XCV glass substrate to replace conventional plastic LGPs by applying the company’s century of excellence in manufacturing diverse glass products,” said Tadashi “Bruce” Murano, general manager of AGC’s Applied Glass Materials General Division. “XCV is a highly advanced glass substrate that enables large, bright TV displays to be produced with 5 mm thinness.”
