e-Ink : Part – 3

Last two weeks we discussed about e-Ink advantages and mechanism. This week we will discuss the latest application as well as potential future of e-Ink.

Secondary display:

Yota phone in 2018 brought a phone which has a secondary e-Ink display at the backside of the phone. This can be used as a reader or non-colorful internet browsing as well as battery saving mode, and this gray-scale display might bring an atheistic look.

Some manufacturers brought a casing for iPhone which has a built-in display at the back. This can show information like phone notification and users can read books on this secondary screen.

Onyx already replaced the main screen with an e-Ink one. For sure, This is not for everyone, but some people of different tastes.

Lenovo just launched a dual-screen laptop that had a normal LCD on top and an e-ink touchscreen where its keyboard would normally be. It was a bit awkward, but also very cool.

In some laptops, a touch-sensitive e-Ink display also replaced the keyboard.

Color e-Ink Display:

Enough with grayscale, Some people just can not accept anything other than the color screen. For them, there’s some good news too. Hisense launched a smartphone that uses e-Ink’s new Paint screen tech this year April and they are shipping these phones to China. 

A similar approach is noticed by several other manufacturers. These displays will not be color vivid very soon. But it brought great improvement in the number of sheds and refresh rates. 

Triton color module with 31.2″, 1280 x 720 color pixel resolution, 16 levels of grayscale, and 4096 colors. still far behind the color LCD monitors, for similar size which offers 4K resolution and 16 million colors.

Electric product tag:

A tiny e-Ink display is placed in the Coin card, a card that can store all your bank cards and membership cards, not only to show card information but also scanable  bar-code and QR-code to mimic the membership card or ID card. Using e-Ind gives it the advantage of least thickness and long battery life.

E-ink product tags and whole display identity cards are already available. But right now these e-tags are too expensive to replace good old paper tags any sooner.

Greyscale Laptop and computer display:

e-Ink enthusiasts are ready to accept a full working laptop e-Ink display.

Onyx BOOX Max2 is equipped with 13.3” E Ink Mobius ePaper display, with full-screen touch and stylus, support Handwriting and Annotation. BOOX Max2 is the first eNote that can simply transform into a monitor through an HDMI connector.

Dasung Paperlike HD-FT third-generation 13.3″ E Ink secondary monitor features a 2200×1650 touch-enabled E Ink display and front-light. The e-paper monitor connects to your computer with HDMI.

Soon with the improvement of the technology we will see e-ink full size HD display on more desks.


Electric dashboard and e-Wall:
Placing a always turned on a to-do list or a digital calendar on the desk would appeal to everyone. And these displays are already here. You can get a Joan Board for 900$ or build yourself one at under a hundred bucks. This might enhance your own productivity or help you manage the office.
The JOAN Premium is a 13″ meeting room scheduler based on Visionect’s popular JOAN platform and its Place & Play technology. This is the largest JOAN assistant device, which presents a detailed overview of all the meetings scheduled to take place in the meeting room, conference hall, or huddle room on that day.
In the near future, we will see the whole wall displays thanks to advancement of e-ink technology. People like forex enthusiasts might benefit much from such idea. Or you might find them useful for house decoration or in the office environment.
