useful lab instrument display = e-paper? OLED? touchscreen?

[John Griessen]

One kind I had hoped for, e-paper, seems too expensive to make a profit from:

Pricing for 500pcs is $9.45 each, Ex Works Hong Kong

Would bio folks care more for that high contrast, visible from the side at a glance look,
and stays displaying last results indefinitely
vs. OLED high contrast display that is on when power is on, dark otherwise?

Touch screen is not part of these, and has to be layered over them just like cell phone construction,
so touch could be added to any kind of display.

Do the e-ink screens have backlights integrated for darker situations?

No, they have very high innate reflectivity -- like paper.
And you can see them from a viewing angle of 15 degrees.
With the power off.

How much information do you need to display? And how important is it for this gadget to be unpluggable?

The e-paper display you linked to is really tiny. I'd rather have a larger OLED or even LCD display that you don't need to squint at, even though that might mean it uses a bit more energy...
