Bendable electronic color paper with Image memory from Fujitsu

by Dhiram Shah

At CEATEC Fujitsu displayed the world’s first film substrate-based bendable color electronic paper with an image memory function. The new electronic paper features vivid color images that are unaffected even when the screen is bent, and features an image memory function that enables continuous display of the same image without the need for electricity. The new electronic paper is constructed of three displaying layers – red, blue, and green. Since no color filters or polarizing layers are required, it features color that is significantly more vivid than conventional reflective-type LCDs. Proprietary Fujitsu technology ensures that screen color is unaffected even when the screen is bent or pressed with fingers. The paper can display 4096 colors and hence you have smooth gradation of images etc.

The new electronic paper features an image memory function that enables
continuous display of the same image even when electricity is turned off
therefore no electricity is required for continuous display. Screen image
can be changed using minimal electricity consumption equivalent to the weak
radio waves used in contactless IC cards. Fujitsu’s new technology significantly
conserves energy by consuming only one one-hundredth to one ten-thousandth
the energy of conventional display technologies.

Anticipated Applications
By leveraging the features of this technology, a wide variety of applications
can be envisioned for Fujitsu’s new electronic paper as a digital medium
that can be handled like paper. Following are some examples:

Transit advertising on trains, information displays on curved surfaces,
and other public display applications that could take advantage of its
light weight and flexibility. Information displayed can be updated based
on the time of day, enabling more effective advertising and informational

Electronic shelf display tags, point-of-purchase displays, restaurant
menus, and other in-store uses. Can also be used for pricing displays
or product information displays that stand out in full color and can be
readily updated.

Operating manuals, work orders, and other short-term information displays,
facilitating the trend toward paperless offices or factories.

Text or images from mobile phones or other mobile devices can be transferred
wirelessly to larger displays for easy viewing.
Use in the home can offer more convenient digital-media devices that can
be carried from room to room.
