Sharp has developed a touch panel that can accurately pick up text written with a ballpoint pen. This sets the device apart from conventional ones that require a stylus with a wider tip. The new liquid crystal display panel has roughly four times the sensitivity of hitherto existing models, making it the world's top performer in that regard, according to Sharp. The Japanese electronics company plans to start domestic mass production of the device next spring and make it a mainstay product in its LCD business.
Sharp's new panel works with ballpoint pens and mechanical pencils with 1mm or even narrower tips. The company's current production lines can make the panel.
