On: E Ink Waveforms are a closely guarded secret

No?

The main advantage is that it's easier on the eyes

People keep saying eInk is better than reflective black and white LCD, such as that found on calculators.

I’m unconvinced, but (obviously) to test this I would have to actually get a monitor sized black and white reflective display, and I can’t find any of those — largest I have found so far is 320x240 for about £200

I haven't seen a reflective black and white LCD matrix that didn't suck. Think TI-82 calculators.

That being said the segmented LCDs like those found in 4 function calculators and wrist watches usually look fantastic.

IMO you do not have to go that far for graphical reflective LCD that didn't suck: TI-89 has one. Also LCDs in Psion handhelds were quite reasonable.

I can't find my TI-89 to compare but I have a TI-85 and TI-83 from the late 90s and the newer 83 has a noticably better screen so you're probably right. I recall being impressed by the TI-92's screen but I sold mine long ago so I have no basis for comparison.

I had a TI-83. Yes, the resolution was terrible by modern standards. The contrast was fine until the batteries started to die.

If I didn’t already have way too much on my personal to-do list, I’d be interested in converting an LCD with a backlight into a reflective one. I assume it’s not possible with all models, but also that it is possible with some.
