Japan's Dai Nippon Printing has launched a light emitting material that can be printed on textiles and used to make light emitting clothing and flexible displays for wearable computers.

Unlike other proposed flexible screens and lighting, known as OLEDs, screens and patterns can be printed using existing screen and offset printing methods.

A bright patch of light is produced when voltage of 3.3V is applied, which is about the same as a normal charge from a domestic battery. Now in the R&D stage the company hopes to commercialise the invention in the near future, it said.
