Solution Integration
e-Paper technology can provide a number of benefits for low-power display applications. Because e-Paper is a bi-stable technology, the system only requires power when the image is changed. For applications requiring a high-contrast, monochrome, static image which changes infrequently, such as retail price labels, product fact tags or meeting room reservation signs, e-Paper displays offer significant advantages.
Chilin Solutions can take your application and design and engineer a complete solution to meet your needs. Customers can leverage Chilin's broad e-Paper experience and resources to create an entirely new turn -key solution, inclusive of display, hardware, firmware and software application.
E-PAPER WITH ZIGBEE TECHNOLOGY
ZigBee is a low-cost, low-power, wireless mesh networking open standard Chilin has used for certain wireless e-Paper solutions. The low cost and broad availability of Zigbee components allows the technology to be widely deployed in wireless control and monitoring applications. The low power requirement allows longer life with smaller batteries, and the mesh networking provides high reliability and larger range.
Readable
• high resolution from any angle
• sunlight readability
• easy to read because it mimics the appearance of ink on paper
Rugged
• flexible,
• lightweight,
• durable
• reliable
Green
• extremely low power
Backlit LCD requires 36 batteries to provide the same service that an e-Paper display can deliver with 1 battery
• e-Paper is a green alternative to paper because it can be changed and re-used in applications that would otherwise require the use of paper
For example, a study out of the University of California Berkeley shows that reading a newspaper electronically releases 32 to 140 times less CO2 and uses 27 times less water than reading the paper version.
Microcapsule Technology
Electronic ink is a proprietary film electronic display material. Although futuristic in concept, electronic ink is a straightforward fusion of existing knowledge in chemistry, physics and electronics. In fact, the white and black pigments used in E Ink are actually the same ones used by the printing industry every day.
The Ink
Electronic ink is made up of millions of tiny microcapsules, about the diameter of a human hair. Each microcapsule contains positively charged white particles and negatively charged black particles suspended in a clear fluid. When a positive or negative electric field is applied, corresponding particles move to the top of the microcapsule where they become visible to the user. This makes the surface appear white or black at that spot.
The Smart Ink Display
To form a smart ink display, the ink is coated onto a sheet of plastic film that is laminated to a layer of circuitry. The circuitry forms a pattern of pixels that can then be controlled by a display driver. The microcapsules are suspended in a liquid "carrier medium" allowing them to be coated using existing coating processes. The final laminate can be applied onto virtually any surface, including glass, plastic, fabric and even paper. Ultimately electronic ink will permit most any surface to become a display, bringing information out of the confines of traditional devices and into the world around us.
