A Modest Proposal

Smart Screens
Sehert said the CPU only accounted for seven per cent of the typical power consumption of a mobile device (al
though the chipset accounted for another 13 per cent). With the LCD sucking up a third of the power consumed

It seems to m
e
that controlling power consumption requires a user eye-tracking mode. As I look at my dual screen setup, at every moment my focus rests only on a small couple of square cm of the screen. Surely with eye tracking it should be possible to dim/fade the rest of the screen, cutting down power consumption.

This might also have advantages for graphics cards/CPU, because you could concentrate on doing most your rendering and aliasing in only the portion of the screen within eye focus. For that to work you’d need some sort of tile-based card technology.
