No. 351: Mono-color electronic paper capable of displaying three colors (November 15, 2011)

Toppan Printing developed new electronic paper that can display a total of three colors including black and white in alliance with a Taiwanese company. They combined Toppan’s monitor with the electronic paper developed by the Taiwanese company. Toppan will market the new product in the Japanese domestic market, while the Taiwanese company will market it in foreign markets. Toppan has already started the test marketing of the new product with a view to placing it on the domestic market within the year. The color to be added to black and white can be picked up from four colors of red, blue, green, and yellow.

The trial product measures 7.2 inches (about 18.28 cm). The reflection coefficient of the new product is more than 30%. It has a high degree of readability because its contrast (difference between light and dark) is 13 to 1. The color part can be positioned anywhere on the display. The new product is energy-saving, the feature that characterizes the existing black and white electronic paper. It will be applied for various purposes, such as signboards in railway stations and boards in meeting rooms.
