E-Ink is a brand name e-paper tech There is a competitor called DES Slurry https://www.youtube.com/watch?v=FdAxyp7cj78 https://www.youtube.com/watch?v=FdAxyp7cj78 It has more colours, better resolution and better contrast... but it's refresh and update speeds are much slower than E-Ink... which hopefully will improve as time progresses We need more competition in this space.
