In this video I will show you how commercial E-Paper displays work and how we can control them easily with an Arduino development board. Along the way we will discover their advantages and disadvantages and compare them to traditional TFT LCDs. Let's get started!

E-paper has another hidden trap for newbies: the e-paper runs on a quite high voltage (several tens of volts, often two rails a + and a -), and, every time you power it down (enter sleep/standby) you throw away the charge in its "high voltage" power supply caps. That's energy you have to put back into them the next time it comes out of standby. This energy isn't in the datasheet power consumption figures, and does add up to quite a bit when you do the math for say a year or two of display updates...
I am currently building a weather station with the 4.2 display and a esp8266. So good ! Just be careful with the partial refresh. Each time you use it, each time it lower the darkness of the rest of the screen. So you need to do a full refresh some time.
I remember first hearing about eInk in 2003. I always wanted to mess with it, but it seemed just too far out of reach to custom-fabricate some interface board and write microcode.
Dude absolutely all of your videos are so well made it's scary.
damn, basically the arduino eats more power than the display, lol
I ve been watching your channel for a while now and everyone of them has been facinating, i really love the latest buy or diy builds using the easy pcbs, you show all the mistakes youve made and fixes and then even after all your hard work some of them youve said better to buy , great videos , great projects keep them coming , oh , Merry Christmas 👍🍻
It is always awesome to watch and learn from you. Thank you for another great video
Another Great video. Thanks for the effort GS, keep inspiring! Happy holidays!
Nice video, cannot wait to see this channel pass its 1 million milestone.
I have this in my Domotic Smart Thermostat and Valves by Netatmo ( great brand by the way). It even stays on after batteries removed ! E-Paper is a great invention !
A local electronics store has started using little e-ink modules to put the prices on the shelves. I think the modules might actually be wireless and they can change the price, name, etc on the fly. As the screen uses no power while it is displaying things they could get away with using them and recharging them only after quite a while.
Thanks for sharing and Happy Holidays !
Micro Watt Henry? I think you've meant to say Watt/Hour, didn't you? :)
I never thought I could buy e-ink screens! As always, this is a great clip and I look forward to seeing those forever! Thank you!
Almost 1M subscribers. It will be well deserved. Can’t wait for more content like this in 2019!
Your description how the e-paper work is on point! Thanks :-).
I just ordered the 8 inch version of this myself! Perfect timing :)
With the LCD display most of the power is used by the LED back light and 1W seems extreme (you will likely damage the LED's at that level).
Hello again mate, thanks for another awesome video!
I learnt a new concept e-paper display (MED) Microencapsulated Electrophoretic Display ....
