At SID Display Week 2019, Corning presents Astra Glass, a new glass substrate is specially formulated for high-performance tablets, notebooks, and 8K TV. Corning shows this innovation, alongside other industry-leading solutions in its advanced glass portfolio, Astra Glass is precisely engineered to enable the higher pixel density of high-performance displays that panel makers require to meet consumer demand for brighter, faster, and more lifelike image. To build a display that meets those performance expectations, panel makers need a thermally and dimensionally stable glass to improve yields while achieving the desired resolution, meeting the precise, high-temperature requirements of oxide processing joining their portfolio of display substrates, alongside EAGLE XG Glass and Lotus NXT Glass, to cover the entire spectrum, Astra Glass enables a range of high-performance panels – from the high end of the a-Si space into IGZO oxide. Its attributes position Astra Glass as the foundation for large-size 8K TVs and high-performance notebooks and tablets with bright picture quality and fast response time.

Lotus NXT Glass provides industry-leading levels of low total pitch variation resulting in heightened resolutions; more energy-efficient displays; and better yields. The improve stability of lot NXT Glass– and, in turn, better total pitch variation performance – enables manufacturers to develop display panels that feature up to 100 pixels per inch higher resolutions or up to 15 percent lower power consumption. Additionally, panel makers can improve cell assembly yields by up to 1.5 percent, is optimized for the expanding LTPS-LCD and LTPS-OLED industries. Featuring superior key attributes for flexible OLED panel manufacturing, Lotus NXT Glass leads the industry, having enabled more than 375 million flexible OLED phones since 2015.
