Is a bistable the best option for a low power LCD?
Yes and no. Bistable is great if your display is not changing very often. It requires power for every change, but no power if it holds the same value for a long time such as a price tag at a shoe store. Also, bistable is more expensive.
If you need a low power LCD that does change, or cost is a concern, then a segment LCD<https://en.wikipedia.org/wiki/Seven-segment_display> is the best option. It draws less than 1mA without a backlight and is simple to program.
They are custom built to the size and segments you need, but the tooling cost is low.
