Fujitsu has unveiled, what it claims is the world’s first electronic paper - a flexible format that can display colour images without using power. The product is targeted at applications that display information or advertisements in public areas. The electronic paper is aimed at displaying colour images that are unaffected even when the screen is bent. The image memory function enables continuous display of the same image without the need for electricity. This electronic paper is made of three displaying layers - red, blue, and green. Since no colour filters or polarising layers are required, Fujitsu claims the device can display colour that is more vivid than reflective-type LCDs. Also, because the screen image does not require repetitive updates to be maintained, the screen does not flicker. According to the company, the electronic paper can be used in conjunction with mobile devices as an easy-to-read and portable display device. The product can be used in applications such as transit advertising on buses and trains, information displays on curved surfaces, and other public display applications such as restaurant menus. The electronic paper will be showcased at the Fujitsu Forum 2005, to be held today and tomorrow in Tokyo. Fujitsu is currently conducting test marketing and practical-use testing, and plans to commercially manufacture the product within fiscal 2006. Many companies are pooling R&D resources to create similar display products. For example, in March, Intel Capital invested an undisclosed amount in E-Ink, a developer of electronic paper display technology. Philips Polymer Vision had also claimed to develop a 5-inch roll-up display, which can be rolled up into a housing when not in use.
