waveshare waveshare 7.5inch E-Ink Display HAT for Raspberry Pi 640x384 Black White Two-Color Display Screen SPI No Backlight Ultra Low Consumption

Having used two of these screens over the past 4 months I can confidently say that these are poor quality screens. They simply do not render images consistently over time. I have experienced two things: 1) Blacks turning into light greys over time (~ 2 days). Blacks in certain parts of the screen simply will not show up as black anymore. 2) Inconsistent pixel activation. Essentially random pixels being activated in large streaks when they are not supposed to be

I brought the screen having done a little research and got exactly what I expected! I'm using it to display a screen of information such as weather, news, local train times and the temperature in my home which updates every five minutes. I found it pretty easy to use a Raspberry Pi Zero WH to drive it using code based on the samples WaveShare provide online. The only disappointment is that it does not support partial screen update, as far as I can tell. It doesn't take too long to update the screen in full though, and my application is not time critical, so all good.

I did like most everyone else did and made a Portal theme calendar. First item came in damaged, but seller replaced that quickly. Display has been running for about a year with no failures.

La nouvelle version de l'écran est carrément mieux que la précédente : meilleure résolution et niveaux de gris. Juste faites attention à la connectique au niveau de l'écran, la mienne s'est décollée après deux semaines de manipulation.

Works as expected. Thank you.
