#587: Quarterlight

Everybody would like their laptop battery to last longer.

Today’s invention is one way to allow that. Normally, when left alone for a while, one’s screen will dim. I suggest applying that by default to all screen real estate, apart from the active window. The screen would thus use a great deal less energy, at the expense of a small amount of extra control circuitry/logic.

It might be possible to have different windows with varying levels of local illumination, depending for example on the recency of last usage (although I can’t think why this would be useful, other than for aesthetic marketing reasons when the machine was on display -or perhaps to draw attention to different windows in a particular order).
