The iPhone’s touch screen is old news by now, so it’s time to move on to the next big thing, right? Of course it is. Sharp’s announcement of its latest LCD touch screen is making a few ripples and for good reason. This here touch screen is a mere 1mm thick, has optical sensors built into each pixel of the LCD and it has a scanner function. All of this on top of the multi-touch functionality we’ve all grown to love. Samples are being shipped out this September with production gearing up in the Spring.
