mariush:
There are other technologies which are sort of like eink but better, here's one example:



It's expensive though.

I am not a fan of LCDs for instrumentation. Glare, low contrast ratio, low resolution.

Give me graphical OLED or VFD for high end, segmented VFD for mid and plain old regular 7 segment LEDs and illuminated indicators (think icons with an LED behind to light up when they're active) for low end.

graphical LCDs and segmented LCDs are actually a "feature" point that turn me off of selecting an instrument.

E-ink would just be a novel(and have obvious problems that are not that easy to solve unless you buy ready-made one, like backlight), LCD is just much better fit for the job

That was not my link or proposition. I'm just somewhat aware of the capabilities of the technology. Again, let's be factual.

I don't quite understand the comment about "ready made". LCD would be too, right? The same applies to both technologies.

Basing a production design on surplus parts is also very risky, unless they are so cheap you can buy a reasonable lifetime's worth of stock.

See, that's a real argument. Power supplies have to be safe.
gardner:
Personally I am another advocate for a bar graph or % of set-current display.  I also want to have the current shown in mA where appropriate.  Here is a craptacular mock-up of a way to shoehorn those features in.
