New E Ink device: Timex Ironman ONE GPS+

E Ink display info: 
1.5" Mirasol display

Timex's Ironman ONE GPS+ is a fitness smartwatch that does not need to pair to a smartphone - it's a 3G connected device by itself and can connect to Timex's fitness web site to upload your data and share with contacts. It also has a messaging applications, music player and GPS. The display is 1.5" color Mirasol display (Qualcomm also provides the chipset and Brew platform for this device).

The Ironman ONE costs $399 or $450 with a heart sensor.

Current promising e-paper technologies

IDTechEx posted an interesting article discussing the current state of the most promising e-paper technologies (E Ink, LiquaVista, Mirasol, Folium Optics' Electrokinetic and Gamma Dynamics' Electrofluidic).

The article discusses the possible applications of each technology.


Phase-change materials could enable ultra-low-power color displays

Researchers at Oxford University developed a phase-change based display. These materials, the same materials used to make some rewrite-able DVD discs, may enable ultra-low-power (non-volatile) full-color displays with a much faster refresh rate compared to E Ink displays.

The researcher use small jolt of power to change the crystal structure of the material, which changes the way light bends when it hit it, and so it changes the color of the material. Light reflects of each of the layers in different ways, canceling some wavelengths and amplifying others—green and blue light might be eliminated, leaving red, for example. Varying the thickness of the layers, or the voltage applied to the phase change material, affects what colors each pixel in a display shows.

Switzerland's PostBus test E Ink bus timetables

PostBust Switzerland is testing a new electronic timetable display at bus stops. These DynPaper displays are based on E Ink and use Plastic Logic's OTFT backplane. The Swiss company hopes that this will make it easier to change timetables in the future and allow daily updating of individual stops.

Currently, the bus timetables are printed on paper. PostBus installed 12 such E Ink timetables. The main objects of the test is to see how reliable these displays are, and how they fare against vandalism and bad weather. If the project is successful, they could equip as many as 14,000 bus stops with the new DynPaper timetables.

ICAP offers an e-paper patent portfolio up for sale

Patent brokerage firm ICAP announced an upcoming sale of an IP package that includes improved electronic reusable paper display technologies from Xerox Corporation and PARC. ICAP will accept bids for this package from July 24 to July 29.

This portfolio offers novel techniques and materials for construction of, and methods of operation of, electronic paper display devices. Also included are electrophoretic displays and various liquid compositions and marking materials for use therein. These inventions provide new products with a wider viewing angle than traditional backlit displays, and an improved image quality resolution, for a better reading experience.

Qualcomm shows next-gen SMI-Mirasol displays with a higher color gamut and pixel density

Qualcomm unveiled their next-generation Mirasol displays that use a single mirrors to achieve a better color gamut than previous Mirasol displays. These new displays are called SMI (Single Mirror IMOD). Qualcomm showed prototype 5.1" , 2560x1440 (577 PPI) displays.

In SMI-IMOD displays, a single pixel can create all colors - there's no need for three different subpixels as in previous generation IMOD displays. An IMOD (Interferometric Modulator) display shows a color using a mirror film that changes its orientation to create a cavity that interferes with the light. An SMI-IMOD pixel has a mirror that change both its orientation and depth - which enables it to show all colors.

E Ink shows a wraparound display for smartwatch applications

E Ink is showing a new flexible wrap-around display aimed towards smart watch applications. The idea is that this will be used to cover the whole smart watch, and can be used to change the entire watch design.

Besides the design, this smart watch (band?) can display information, notifications, heart rate, etc.
