Mack DeGeurin, writing at Popular Science, covered a team at the National University of Singapore College of Design and Engineering that built what it calls the first touchscreen woven into a garment. The display is 96 by 54 pixels and sits on the inner forearm, measuring 6.6 by 4.3 inches. It supports multitouch and 8-bit color.

Each display fiber is a thread about one millimeter thick holding a strip of LEDs.
