Last month PopSlate launched a crowdfunding campaign to finalize development and production of their 2nd-gen iPhone case, the PopSlate 2. The campaign was a hug success, and the company raised over $1.1 million.

The PopSlate 2 offers a 4.7" 800x450 E Ink display for the back of your phone. The case adds 4 mm to your phone, and connects to the phone via a Lightning connector that also charges your phone from the PopSlate's battery. The PopSlate 2 supports iPhone 6, 6S, 6 plus and 6S Plus.

E Ink Holdings developed a new 2.9" E Ink ultra-thin display turn key solution. The new system combines the e-paper display with a complete system for customers to use in mobile terminal devices.

E Ink says that the new display is especially suited as a secondary smartphone display. The system does not use a battery and rely on NFC for the driving power and data transmission.

Researchers from Microsoft and the University of Applied Sciences Upper Austria developed a new smartphone case prototype called FlexCase -that adds a secondary flexible E Ink touch display.

FlexCase enables users to interact with their phone in several ways - including bending it to flip pages, zoom and navigate. The basic concept is similar to OLED-based prototypes demonstrated in the past. . Back in 2011 Nokia demonstrated an OLED concept called the Kinetic, and in 2015 AUO demonstrated a bendable 5" AMOLED display that includes a film-type touch sensor.

YotaPhone's first-gen E Ink / LCD mobile phone started shipping in Europe only a few months ago, and the Russian company already revealed a new prototype. The main new feature in this new prototype is the 4.7" E Ink display - it now supports touch and can now be used for e-mails, SMS messages, browsing and much more.

The 4.3" 720p LCD has been replaced by a larger display, a 5" Full-HD Super AMOLED display (the same one used by Samsung's Galaxy S4). Seems like this is a really good upgrade, and hopefully YotaPhone will be able to release this new phone soon.

Remember YotaPhone's smartphone with the two 4.3" displays, a 720x1280 LCD and a 640 × 360 E Ink? The company promised to ship the phone in November, and now it announced that it will ship in time for the holidays, but only next month. The phone will cost €500 in Europe. 

The YotaPhone will have a dual-core 1.7Ghz PU, 2GB of RAM and 32GB of storage. It is an exciting phone, but today several companies offer smartphone covers with E Ink panels on them which may be a better solution for most people.

Remember YotaPhone's smartphone with the two 4.3" displays, a 720x1280 LCD and a 640 × 360 E Ink? According to reports, the company is finally getting ready to ship their groundbreaking phone in November 2013. It will cost €500 in Europe at launch. 

The YotaPhone will have a dual-core 1.7Ghz PU, 2GB of RAM and 32GB of storage. It is an exciting phone, but today several companies offer smartphone covers with E Ink panels on them which may be a better solution for most people.

Back in October 2012 we posted about an Onyx E Ink phone prototype, and now we hear reports that the company plans to launch this phone soon. The so-called E43 Android phone sports a 4.3" E Ink panel and a 1 Ghz CPU.

The company is also working on two new E Ink e-readers. Both will have Wi-Fi, a touch display, 4GB of RAM and a 1 GHz CPU. They will actually be Android (v2.3) tablets, limited by the E Ink display. The BOOX R65 will have an IR touchscreen while the BOOX C65 will have a capacitive touchscreen.

E Ink produced several E Ink phone prototypes (only five of those, in fact), and Engadget posted a short hands-on review of one of them. These are Android (V2.3.5) phones with a touch E Ink display. The prototype is buggy and slow, and obviously not intended to be released as a product - but rather as a tool for partners to play with and use to build devices with:

E Ink also gave the Engadget guys a chance to play with a flexible E Ink display, you can read more about it in the source link below.

Yota Devices (a spin-off from Russia's Yota telecom) is the company behind E Ink's dual-display (LCD/ E Ink) phone shown at IFA 2012. Back in September E Ink said we should expect such a device in 2013 - and Yota indeed says they will launch it in Q3 2013. Yota currently has a fully working prototype (called the YotaPhone) that has two 4.3" displays, a 720x1280 LCD and a 200 dpi E Ink.

Other features of this interesting phone include a dual-core 1.5Ghz CPU, 2GB of RAM and at least 32 GB of flash memory, LTE and a 12 mp camera. The whole phone weighs just 140 grams and is less than 10 mm thick. Yota says they are already in talks with US and European carriers to launch this phone overseas.

China's Onyx is working on an E Ink smartphone running Android. Obviously Android isn't perfect on E Ink (no color, slow refreshes) - but this is an interesting concept and might be quite usable for some people. Battery life is said to be around 1 week, but this will obviously depends on how much you talk and use the phone.

During IFA 2012 in September, E Ink themselves showed a prototype dual-screen smartphone with an LCD on side and an E Ink display on the other side. This is a really clever idea, but in the meantime we'll have to settle with Onyx's E Ink only phone...
