Secondary screens

From MobileDesign

This is a stub and must be expanded

External screens on flips, end-screens on some candybars, and flippable (two-sided) device-specific patterns. Also, remote screens for multi-part or PAN-aware devices (e.g. Symbol wrist readout on ring-scanner).

An idea for a pattern is that external screens should be on all the time, or turn on based on "look at the device" sensing. As this is a glancable screen and the clock and other device status should be easily readable without button activation.

Note that external screens can be interactive, with menu display, etc. Do not have to be static displays (N75 and KRZR both have this function, to different levels).
