Overlooking complaints of lack of backlighting, the Panic Playdate's screen IMHO is its stand out feature. It's a "Sharp Memory LCD" which has the appearance of e-ink and shares it's ability to continue to display an image when unpowered, but has the active refresh rate of a more standard LCD. It's frankly stunning to see in real life, and it's hard to describe how crisp it looks. Videos do not do it justice. It's truly unlike any other display I have seen. I would absolutely adore a kindle sized e-reader with the technology, and am hopeful the future brings one.

The Daylight tablet is the closest to Playdate display among the tablets listed in the article.

  Some people on Reddit speculate the Daylight Computer is also a Sharp screen. Unsure whether memory LCD and IGZO are related as I'm very new to this space (and trying not to fall too deep into the rabbit hole) The play date screen is beautiful. So is the daylight computer but no colour is just a deal breaker for me unfortunately. Some charts/diagrams use colours and being unable to understand how the colour is being used is probably going to end up being too annoying in the end for my intended usage even tho I am predominantly looking to read (pdfs and blogs) For books I still prefer the real thing whenever possible EDIT source - https://old.reddit.com/r/eink/comments/1dw9a7g/daylight_computer/lbxeleb/ https://old.reddit.com/r/eink/comments/1dw9a7g/daylight_comp...

    I ran some Daylight Computer photos from a trip to their factory through Google Lens and it was the Sharp factory in Japan. No doubt. It seems that they took a certain Sharp screen and simply took off the colour layer. Citation needed.

So Sharp Memory LCD isn't quite unpowered, but it is measured in hundreds of microwatts of power.... Nearly power free. And this is while updating the screen. EInk is truly 0 energy to hold an image.... but each refresh uses a lot of energy. IIRC, the breakeven vs Sharps memory LCD was like 15-minute refreshes. ---------- Many battery packs have internal leakage in the ~50 microwatts region just a magnitude below to the power needed for Memory LCD. So Sharp Memory LCD is close to the point where we stop caring about power consumption at all. But not QUITE zero or otherwise ignored. Still very impressive how low they got.
