E-paper Display

e-paper-01

E-Paper technology offers real advantages for low-power display applications. Because e-Paper is a bi-stable form of technology, the system only requires power when the image changes. For applications with high contrast, black and white, or a static image that does not change often, such as price tags in stores, product specification tags, or meeting room booking boards, E-Paper displays offer significant advantages.

E-Ink and Microcapsule technology

Electronic ink is a patented film electronic display material. Although it seems futuristic, electronic ink is the simple result of modern knowledge in chemistry, physics, and electronics. The white and black pigments in E-Ink are effectively the same as those used every day in the printing industry. The E-Ink or electronic ink consists of millions of tiny microcapsules with a diameter comparable to that of one human hair. Every microcapsule contains positively charged white particles and negatively charged black particles, which are trapped inside a clear liquid. With a positive or negative electric field charge, the corresponding pigment particles transfer to the surface, so that the display at that location is coloured either white or black.

E-Paper advantages

e-paper
  • High resolution from any angle
  • Legible in direct sunlight
  • Reads like ink on paper
  • High contrast and extremely thin
  • Flexible, lightweight and durable
  • Captures the image fully without power

In order to make a smart ink screen, ink is applied to a plastic film laminated on an electronic circuit. The circuit forms a pattern of pixels which can then be controlled by a control program. The microcapsules float in a liquid "carrier medium" which allows them to be coated by existing coating processes. The final laminate can be applied to virtually any surface, including glass, plastic, fabric, and even paper. Electronic ink can make almost any surface into a display, so that the traditional boundaries between print and electronic media are becoming increasingly blurred.
