I have periodically reviewed the e-Ink market looking for usable products w ithout a lot of experimentation. Most of what I find are displays without driver boards, a few high priced combos of displays with separate driver bo ards, but few docs and very few displays an driver boards with some sort of docs and/or library support. The one thing that always seems to be missin g is an easy to find and easy to read document describing exactly what they will do and what they won't do. Mostly the docs are a couple of poorly ma de videos with no real explanation.
I saw one video (don't recall the vendor or site) showing a display with pa rtial updates such as would be needed for a display of a real time device s uch as a... ventilator for example. That looks promising. But the display is monochrome and I still didn't find any docs on exactly how it would be interfaced to a system.
My main interest in them is to provide a display optimally viewable in any lighting.
There seems to be more than one manufacturer of these displays. When they are sold by third parties (mostly through Aliexpress) it is hard to tell wh ich brand of display they are. If I understand correctly one company owns the patents with multiple manufacturers licensing.
All of the inexpensive displays are pretty tiny. One maker includes touch screens even on 1.5 inch displays! My finger tip is not much smaller than that. The prices rise rapidly with size. A 4 inch display is pushing $40.
Anyone used any of these displays? Anyone happy with these displays? Tips ? Cautions?
