A few weeks ago, I made a video about this small 1.5" e-paper display and I built a simple thermometer with it in another video. You can watch those videos by clicking on the cards here. I really like e-paper displays and when I discovered this big 2.9" inch e-paper display I ordered one to test it. The display costs around 23$, you can find a link to it below. Compared to the 1.54" inch display which costs around 20$ the bigger display offers better value for money, but still expensive for most projects.
The reason I like to use e-paper displays is that they have some unique characteristics. E-Paper or Electronic paper are displays that unlike traditional LCD or OLED displays does not emit light but reflect light. It is like the ink on the paper. This characteristic makes e-paper displays very comfortable to read, and they have excellent readability under direct sunlight. Another great thing about e-paper displays is that they can hold static text and images for months without electricity! Yes, that's correct, the display can show text and images even when it is off! That makes e-paper displays ideal for low powered projects!
Unfortunately, there are some disadvantages as well. The price of e-paper displays is still very high. Another significant disadvantage is that e-paper displays take a lot of time to update, as much as 2-3 seconds. So, they are only helpful for static text and images and not animations.
