- In this video I explain how e-ink displays work in e-readers. I explain why e-ink displays have such a low refresh rate. I also explain why e-readers have such good battery life. And I talk about where else e-ink displays can be used besides e-readers.

Hi there, been binging your vids for past an hour and it's been a blast, please don't stop on your youtube, it'll surely grow, i really have high hopes in you!
P.S you remind me of lemmino
Thank you for your support! It means a lot to me. And yes, I definitely won't stop. In fact, there will be a new video tomorrow. It's going to be pretty interesting!
Some bus stops now use eink displays for the departure board. If it refreshes once every 30 seconds during the day(60 seconds at night) then they'll still take like 12 years before they hit the 10,000,000 refreshes that the displays are rated for. I assume they're more reliable than LCDs/dot matrix displays too since they're doing nothing most of the time but this is a guess. Definitely use a tiny fraction of the power though which would let them be powered by a small solar panel and small battery(to stay on overnight) whereas with the other types of displays you'd have to run a grid power connection to the bus stop. Would still need a little control board and 3g though to give the display it's data, but still much cheaper than connecting the bus stop to the grid since those can be solar too.
This is a great example of where e-ink displays should be used. I don't see the point in putting them in computer screens or smartphones. That's not the best place for them. But timetables are a great place for e-ink displays. You're right, they're reliable, they save energy, and are just as good as LCD/dot-matrix displays in terms of readability.
You have consistently been putting out interesting and high quality videos! Looking forward to the next one.
And please don’t focus too much on the comments regarding your accent. Your English is nearly perfect and your accent is completely understandable.
Thank you for your kind words! I really appreciate your support. By the way, there will be a new video tomorrow and it'll be quite interesting!
How can the Pigments be made so that it can still work below -10c°?
The problem at low temperatures is not with the pigment particles, but with other components of e-readers. The battery stops working properly, losing power quickly, the plastic becomes brittle like glass, and the oil inside the capsules becomes too viscous to allow the particles to move. So, to allow e-readers to work at extremely low temperatures, we need to fix all of the things I mentioned. But even if we fix the e-ink displays, the battery still won't work properly. Smartphones (and other devices with batteries) don't work at extremely low or high temperatures either, for the same reason. The problem is the battery.
