Dear : Any guidelines on E-Ink / B&W/grayscale / low-refresh rate app design / UI/UX?

I've recently come into possession of an e-ink book reader, and am discovering the joys (seriously) and limitations (dittos) of e-ink displays and software designed for them.

I've just begun looking for any information concerning design guidance for e-ink devices, and am coming up very short. If you're aware of any such resources please respond to thread.

Boosts welcomed.


Only thing I know about E-ink is that it might be some sort of liquid crystal.

Ah; it's Liquid Crystal Display, but with something other than liquid crystal. Neat!

Liquid Crystal Display: Displays stuff by running electricity through liquid crystals to change their orientation. Often backlit, but originally was not. (i.e. cheap calculators, overpriced TI calculators)

Liquid Paper Display: Displays stuff by running electricity through an emulsion to change the orientation of suspended particles


@TransGal4872 LCD requires constant power to the display to maintain the pattern. Electronic paper / e-ink does not. A charge is use to impart the pattern, but not to maintain it (the dispaly retains its last-applied state in the absence of power or charge).

LCD operates based on light polarisation, which means that the maximum light/dark contrast ratio is 50%. Electronic paper operates on direct light absorption, with contrast limited only by the lightness and darkness of the particles (white) and dye (black) within the display. LCD viewing is impaired by wearing of polarised lenses (as with many sunglasses).

The net effect has some similarities. The mechanisms and characteristics are quite distinct.

Electronic paper is not based on liquid-crystal technologies at all.
