Description

What is an E-Paper?

E-Paper, sometimes called E-Ink is a technology that replicates the look of ordinary ink on paper. Normally, traditional displays use backlighting to illuminate pixels and display an image whereas in E-Paper displays, there is an electrically charged surface and the movement of electrically charged molecules in an electric field helps to display an image on the screen. When the user looks at the E-Paper screen, the light from the environment gets reflected from the surface of the E-Paper and reaches the eyes. 

Advantages Over Traditional Displays

E-Paper screens are bi-stable, which means unlike traditional displays that refresh at about 60 times per second and require a power source to retain the content, an E-Paper will retain a static image for weeks without electricity and needs power only when the content on the screen needs to be changed. Also, they offer paper-like readability where they can heavily reduce the strain on the eyes while being able to use outdoors under bright sunlight. E-Papers have wide viewing angles and have high-resolution displays with no-glare.

Power E-Paper Using NFC?

As mentioned before, E-Papers only need power when the content needs to be updated on the screen. What if you can use your phone to power the E-Paper display in order to update the content? If your phone has NFC (Near-Field Communication), which is a short-range wireless data transfer technology, you can power the E-Paper display using your phone, since NFC signals carry power with them.

This 2.9-Inch E-Paper adopts Novel Passive NFC Technology and it can help you get out of the trouble of using batteries since it can function without any batteries.

The display on this E-Paper is refreshed using NFC Power and its operation is very stable. 

How does it Work?

In order to refresh the content on the display, you need to use a smartphone with an NFC function or an NFC Reader. Just bring the smartphone or reader close to the E-Paper in order for wireless powering and data transfer.

It comes with an Android APP which is easy to setup. You can just use the APP and swipe the phone on the E-Paper like swiping a credit card!

The E-Paper can be refreshed by an ST25R3911B NFC Board as follows
