The LCD 27 "touch exists, use it?

The manufacture of touch screens large problem. The touch technology is most effective (projected capacitive screen) is ubiquitous on smartphones, but hardly applicable to slabs 24 inches or more. The company Perceptive Pixel, however, found a way to make a touch screen 27 ". Of the large slabs, the transistors that drive the LCD generates interference to the sensors.

To reduce interference, it is necessary to remove the supporting glass layer touch transistors, which then creates reflections and parallax phenomenon very problematic for a touchscreen. Perceptive Pixel has resolved these shortcomings with an optical link. This material has a refractive index very close to the glass, it minimizes the refraction of light passing through the glass layer and hence the parallax.

The LCD panel itself is that of the iMac: a IPS 2560 x 1440 pixels. Its LED backlight assigned a brightness of 400 cd / m2. Perceptive Pixel announces immediate availability. What will the manufacturer to integrated into a screen or a computer?
