That video is a demo from almost a decade ago, the current generation ones are better, but I couldn’t find a good demo outside of hobbyists rambling.
This is without a doubt the biggest waste of potential I’ve seen in the screen market and the fact no one uses memory lcd type displays for portable displays is a crime which probably involves patents. It has full color, fast refresh rates, low power draws that extend battery lives to months between charges and are just fantastic for things the picture just needs to be decent on.
That’s why it wasn’t used. People want bright displays.
Edit: the new Casio G-shock line for surfers, the GBX100 series uses memory LCD. Apparently it’s only since 2019 that Sharp (who patented the technology) were charging extortionate rates for anyone who wanted to use it. Hence its use was pretty much exclusive to hobbyists until now.
We are talking about an e-ink competitor.
but e-ink can have a backlight, according to the memory lcd patent, light sources from behind render the whole screen unreadable. I think thats at least part of why its only been used for watches, alongside the high rates demanded by Sharp
E-ink cannot have a backlight, they are opaque so to get a “backlight” they use a front light which could be done for this as well. E-ink has also been famously crippled by high rates and patents which only recently expired which is the cause in the sudden resurgence of interest in e-ink technology.
fair enough, my knowledge of e-ink is limited, I know a lot more about LCD screens.
