How E Ink Works

Picture this: a screen that doesn’t give you eye fatigue after staring at it for a long period of time, lasts for weeks on a single charge, and offers glorious full color.

Picture this no longer—this is reality. E Ink is finally in color, and 2020 could finally be E Ink’s year to shine. E Ink devices with color displays, like the Hisense A5C and the PocketBook Color, are beginning to hit the market, opening up the use cases for these devices. Imagine reading a comic book or manga on a full-color ereader. Pretty wicked, right?

E Ink was introduced in the late ‘90s, so this is isn’t exactly new technology blowing bloggers’ minds. But it is pretty damn cool, even today.

E Ink consists of basically the same type of liquid that comes in a pen. But instead of depositing the ink on paper like humans have done for hundreds of years, E Ink comes in tiny capsules the diameter of a single human hair. Within these capsules, pigments—commonly black and white—are bonded with a positive or negative charge. To make something visible on an E Ink display, an electrical field charge is sent to the bottom of the display, repelling and attracting the ink within millions of capsules until an image is produced.

My hope is continued improvement on resolution & color depth -- because color e-ink would be perfect for digital art frames. With no glare or backlight, the average person could have believable museum-quality artwork on-demand in their home.

I bought an E ink reader today and was curious as to why I wasn’t getting eye fatigue after hours of reading, like I used to have when I read on my phone after 30 minutes, so thanks bc you really cleared that up for me. And I think it’s really going to be the future of technology once it’s improved well enough.

E-ink with a usable refresh rate and colour would be SICK

After a bad concussion last year, I can’t look at regular screens very long without eye and head pain. E ink is a game changer for people like me. I’ve always thought it was fascinating, and it baffles me why there are so many filters and glasses out there to help our eyes cope with LCD screens, instead of making screens like this that don’t hurt us.

I am a huge nerd for E INK and I've been waiting for eink color for way too long...

Honestly a part of my wishes that e ink technology does not improve because then future e readers wouldnt have that sluggish feel that kinda convinces you into treating the device like a book

[Oshanii]

hope that e-ink technology will continue to improve. even if video will be poor quality it doesn't matter imo, when i work on a computer i have to spend so many hours a day looking at a screen and i don't even watch video. it could improve eye health for so many people.

According to research, people generally learn better with paper than computer screen. And it could translate to better performance and effectiveness using EINK than LCD screens.

With color this technology has a lot of possibilities

They don't work very well in cold weather. I have a Sony smartband talk which has an e ink screen when it's about 1°C it struggles. You can see the screen doing multiple refreshes.. I assume that's because the pigment is suspended in a liquid

Very well explained and animated. Love the bean animation :-) e-ink screens could be a screen standard if they can become as nearly as fast as LED/LCD's
