Like the N8s nice sleep state clock. Something along the lines of avoiding common practice, and using best practice (OLED power per lit pixel) - Also, retroreflectivity... NEED NAME, UNIFYING PRINCIPLE BETTER THAN "CLEVER"- May be I mean something about technical context. If that is a thing. use the best tech your budget allows (retro-reflective). Use your tech right: AMOLED color for battery conservation, turn off backlight on unused screens if you know from sensors (fold or rotate to the table.) Turn oft display driving if backlight off and no reflexive works. Just examples, rally... Good enoughto call the principle a pattern?
