So if your looking for a screen, you will find many different stores selling many different options. When I was looking for screens for my TinyPi project, it didnt seem to matter where the screen came from, they all worked the same.
E-ink seems to be a very different animal all together! each screen seems to have different properties, and even when the datasheet says it is the same driver IC, they are configured in different ways.
Before we go any further, let me just take a moment to shout out to the 'screen whisperer' Larry Bank. He has worked with me, tweaking his screen library to get the most out of these screens, without his work, I would still be struggling with bits of demo code
Screen 1
The first screen I ordered looked lush!! the background was frosty white and the contrast was brilliant. With a bit of tweaking the refresh rate was ok, but needed to be faster.
Screen 2
Enter screen 2, used a supplier that I had used in the past, the screen was much greyer, and it didnt look anywhere near as nice. The fast refresh was not working out of the box, but I didnt see the point of trying to fix it, as the screen didnt look as nice.
Screen 3
Talking to a friend and they told me about another supplier. They have their screens listed as 'fast update' which was music to my ears. After an impromptu 9 day holiday at the airport, the screens landed. The difference was quite remarkable!!
running the same code on both screens, the new one has a much more savage flash, but its over so much faster than it makes a massive difference. With some demo code that lets just just type random stuff onto the screen, you can see its pretty usable, and you can do many fast updates with no obvious grain appearing on the screen.
the hacking continues....
