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.

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.

Plastic Logic spins-off its technology arm, to focus on E Ink development and production

Feb 04, 2015

Plastic Logic, the OTFT backplane developer and EPD producer has split into two companies. Plastic Logic will remain as an EPD developer and producer (based in Dresden, Germany) while FlexEnable (based in Cambridge, UK) will handle the OTFT backplane development and offer technology licenses to display makers.

Here's an article from OLED-Info explaining Plastic Logic's technology. In September 2014 Plastic Logic demonstrated the world's first display based on a graphene backplane (a 150-PPI active-matrix E Ink panel).
