E-Paper – Technology Overview

Release: November 2016

a d ko m . d e Basics of the E-Paper Technology:

1975 Development at the Xerox Palo Alto Research Center 1990 Formation of the MIT Spin off

Operating mode of the E-Paper Technology:

The E INK fluid consists of pellets which contain negatively charged black- and positively charged white flakes. They are enclosed in the sphere. The medium (pellet) is embedded in a light oil. By applying voltage, the flakes can be drawn either to the front- or back

• f the layer / fluid to display the desired content.

a d ko m . d e Construction of an E-Paper:

The structure of an e-paper is clear: Layer 1 is a transparent, waterproof protective foil, which is followed by layer 2 with the actual E INK film. The 3rd layer includes the base substrate, which may consist out of PCB, FPC, PET or glass. A waterproofed protection foil in Layer 4 is finally covering the construction. E-paper, are also named as electrophoretic displays or in short form EPDs, are high-resolution and can in partial addressing of the particles represent several grey shades.

a d ko m . d e Advantages of E-Papers:

• Bi-Stability – Power consumption only on changes of the

display content. Powerless during periods of unchanged representation of the displayed Information.

• Information can be displayed unchanged over a long

period of time.

• Wide viewing angle from all sides
• High Contrast
• High-resolution
• Representation of grey scales
• Very low overall height
• Reflective – good readability without backlighting -

even when exposed to direct sunlight

• Suitable for battery applications.

Available as:

• Graphic glass based E-Paper within standard sizes.

Also as colored E-Paper B/W/R available

• Customized Segment E-Paper
• Flexible, customized Segment E-Paper
