Samsung patents a mobile phone cover with an E Ink display

Jan 23, 2017

Samsung filed a patent in Korea for a mobile phone cover that includes an E Ink display to show notifications. Some covers include a transparent part (or just a hole) through which you can see the display - and if it's an OLED, it makes sense because this uses very little power (only lit pixels draw power in an OLED display).

This is just a patent application for now, but it will be interesting if Samsung actually produced such an accessory for one of its future or present smartphones.

Graphene membranes may hold the key to low-power color e-paper

Nov 10, 2016

Researchers from the Delft University of Technology in the Netherlands designed graphene-based "mechanical pixels" that could, among other applications, be someday used to enable color IMOD e-paper displays.

In these so-called "graphene balloons", a double layer of graphene (two atoms thick) is deposited on top of circular indents cut into silicon. The graphene membranes enclose air inside the cavities, and the position of the membranes can be changed by applying a pressure difference between the inside and the outside. When the membranes are closer to the silicon they appear blue; when the membranes are pushed away they appear red.

Microsoft research developed a wireless energy-neutral E Ink display

Oct 23, 2016

Microsoft Research developed a small e-paper (E Ink) based display that harvests its entire energy using photo-voltaic cells on the back. Using low-energy bluetooth the device connects tot he network every 1-25 minutes (depends on the ambient lighting) to update the display.

The display itself seems very small (around 2-3 inch in size and is a very low resolution one). This is a very neat little gadget, although it's unlikely this will be turned into a real commercial product, at this stage it is just a research project.

The E Ink label will display personalized content that can be pushed to the packaging label as a communication interface, delivering vital information to patients and creating a gateway to improve patient engagement.

Guangzou OED develops a graphene-based e-paper technology, to start making displays within a year

May 01, 2016

China-based e-paper developer Guangzou OED Technologies announced that it developed a new graphene e-paper technology. The company aims to start producing these new screens within a year.

Graphene is the world's strongest and most conductive (to both electricity and heat) material, and it is set to revolutionize many industries - including the display industry. The company says that the new graphene-based paper is brighter and more flexible. The graphene paper is also said to have "more intensity", but I'm not sure what this means.

E Ink and Vanzo developed a dual-screen mobile phone reference platform

Apr 30, 2016

E Ink Holdings announced that it collaborated with Vanzo Technology to develop a dual-screen mobile phone turnkey solution. The system is based on the MediaTek (MTK) platform and combines E Ink e Paper technology with Vanzo’s software and APP.

E Ink says that this new solution will enable mobile phone makers to shorten product development time and investment for dual screen devices.
