E Ink announced a new thin and lightweight EPD technology branded E Ink Fina. The Fina uses a very thin glass substrate that enables it to be lighter and thinner than previous E Ink displays. They weigh less than 50% compared to glass-based LCDs and are less than 50% thick. A 13.3" Fina display weighs about 60 grams.
E Ink also announced the first e-reader to use the Fina, the PocketBook CAD reader. This 13.3" device sports a 1Ghz dual-core CPU, 2GB of RAM, 16 GB of storage, a large 8000 mAh battery, Wi-Fi, 3G and it runs Android 4.0.4. It includes a Wacom digitizer for both touch and stylus input.
Two months ago we reported about Shenzhen Ocean Blue Technology's bid to raise $2,000 in order to build the world's first E Ink monitor - which is actually an E Ink (6" , 800x600) e-reader that doubles as a monitor using a stand and a computer connection that will sell for $99. That campaign was succesful and the company now embarks in their second crowdfunding project.
The RockthEink project aims to build an E Ink SDK that uses a Cortex A8 RK2918 1GHz CPU -Supporting both TFT/LCD panel and e-paper panels. RockthEink will support 7inch TFT/LCD and different E-INK panels like 6, 8, 9.7, 13.3 inch 16-grey level as well as 8" color E Ink (Triton). This time SZOBT are trying to raise $5,000. Each SDK board will cost $79.
CopyTele (CTI) announced that it has been awarded two new US display patents. One of these patents (#8,519,944) covers e-paper resolution, contrast and response time improvements for the generation of images using a dual particle system. The new patent is related to Nano Field Emission Display technology (nFED). CTI now has 14 electrophoretic display US patents and 24 nFED US patents.
In January 2013 CopyTele (CTI) filed a lawsuit against E Ink Holdings, alleging an elaborate scheme to steal valuable, patented electrophoretic display technologies. This lawsuit was later dismissed. The company also filed a suit against AU Optronics and that lawsuit shall be adjudicated via arbitration.
PocketBook to use Plastic Logic's 4.8" flexible E Ink panels in the next-gen smartphone e-book cover CoverReader
PocketBook's CoverReader is a smart cover for mobile phones that adds an e-reader functionality via a 4.8" E Ink display. It integrates with the Android OS to allow you to easily view books and information on the E Ink panel. The first model will ship for Samsung's Galaxy S4 soon, and the company plans to develop more versions for more Samsung, HTC and Sony phones.
PocketBook also announced that they will use Plastic Logic's flexible 4.8" E Ink displays in the next-gen CoverBook. The current generation CoverBook uses a glass base panel. PocketBook says that the Plastic Logic's flexible EPD 4.8" display will be manufactured in Plastic Logic's Dresden facility. This new display has a range of benefits - such screens are flexible, shatterproof, ultra-thin, ultra-lightweight, power saving and daylight readable.
E Ink introduced a new monochrome panel technology called Carta. The Carta offers 50% better contrast and a 20% improvement in reflectance a(more whiteness). Amazon's recently announced new Paperwhite e-reader uses Carta displays.
Researchers from the University of Washington, the University of Massachusetts and Intel Labs developed an E Ink display that is powered wirelessly using NFC. They used an NFC tag that includes a wireless power harvester microchip and 1mAh battery (to capture and store the energy). The E Ink display is 2.7" in size.
A single NFC transfer can be used to get 0.5Mb of data - or about 20 pages, and it gives energy enough to view all of those pages - several times over.
A new research project, DisplayStacks, integrates several flexible E Ink panels into a single display system
The Human Media Lab at Queen’s University in Ontario's new project, DisplayStacks, uses several flexible E Ink panels together that communicate between them using sensors to integrate them into a compound display.
The researchers explain that DisplayStacks basically enables physical stacking of digital documents via piles of flexible E Ink displays. With a conductive dot pattern sensor attached to the flexible dis- play, the system dynamically tracks the position and orientation of these displays in relation to one another. This enables several asymmetric bimanual interaction mechanisms for access and manipulation of information.
