KDDI R&D Laboratories Inc prototyped the "Portable Viewer System," which wirelessly transmits an image stored in a mobile phone and displays it on a 13.1-inch color electronic paper display.

"This is the first electronic paper that displays images stored in a mobile phone," the company said.

The system transmits an image in a handset using infrared and displays it on an electronic paper display. The display only has a power button because a handset is used for all other operations.

The company used an electronic paper display that employs Brigdestone Corp's Electronic Liquid Powder technology and renders 4,096 colors. It takes about 12 seconds for the display to redraw the entire image on the screen.

In the finance and insurance areas, there has been a strong need for a tool that can display personal information and other data at an appropriate size while ensuring security of the information.

The company developed this system, assuming that it would be used to display an almost full-scale A4 size pamphlet, for example, while ensuring high security using mobile phone functions such as remote lock and remote data deletion.
