Toshiba / Matsushita optical pen touch screen

A new 3.5-inch LCD is out from Toshiba Matsushita Display Technology, and it features direct input via optical pen.
Touch screen LCDs are nothing new, but that's beside the point — since this setup uses optics, it technically isn't a
"touch" screen. An optical sensor and processor are literally embedded into the display's glass, enabling it to read signals from an optical pen. The end result may be the same as a touch screen, but since the entire system is integrated into the glass of the LCD itself, you don't have any of the contrast/brightness loss or hardware overhead that is normally associated with slapping a pressure or capacitative sensitive membrane on top of a standard LCD. With a 240 x 320 resolution, this looks like it could be a nice candidate for the LCD of Panasonic's next digital camera.
