CBC News is reporting that Sharp has developed, and will mass produce, touch-screen glass that is about half the thickness of today's generation of screens, and because it does not use a film covering it will produce sharper images. The technology embeds an optical sensor in each pixel of the screen, will allow for multiple touch points on a single screen at the same time, and has scanning technology built in. The screen will go into production next year and can be made up to ~30 centimetres in width.
