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

Very easy to use, great documentation for installation etc

Very happy with this screen. I have the first gen screen and I've been using it for about 5 years now as a weather and calendar dashboard. I have the Waveshare 7.5 Inch V1 from many years ago. Just search for simple waveshare epaper dashboard by mendhak. I've attached it to a RPI Zero, and put it in a picture frame. The screen doesn't take too long to refresh, it used to be 30 seconds but the latest code brings it down to less than 10 seconds.

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.
