AGC launch sales of glass substrate for AR/MR glasses

AGC with headquarters in Tokyo has succeeded in developing a high-transparency, high-refractive-index glass substrate for use in AR/MR glasses. The company has already established a mass production system for the glass in Japan and plans to launch sales from February 2019.

The development of displays that virtually augment the world around us by superimposing virtual visual info onto our view of the real world has been gathering momentum in recent years. In particular, eyeglass-fashioned wearable devices called “AR glasses” or “MR glasses,” which are able to display AR (augmented reality) or MR (mixed reality), have been capturing headlines. The market for these AR/MR glasses is expected to expand as the next-generation device following smartphones.

For the next-generation device, AGC has been developing and proposing glass substrates for semiconductor packages and optical electronic components with a wide range of characteristics. This has led to the new successful development of a high-transparency, high-refractive-index glass substrate ideal for use in AR/MR glasses, which the company had started researching and developing a few years ago

Glass substrate for AR/MR glasses requires a ‘high refractive index’ to extend the viewing angle as well as “high transparency” to vividly show images. It also requires highly advanced glass processing technology to transmit images with extreme accuracy, for instance by achieving high flatness and smooth surfaces. With its high refractive index and high transparency, this newly-developed glass substrate is a product that combines all these characteristics.
