Power dissipation control for a visual display screen

摘要

A visual display screen is partitioned into a plurality of screen portions. Power drivers associated with the screen portions are grouped selectively according to the number of screen portions. The power supplied to each group of drivers is selectively controlled to select which screen portions receive power at any given time. In the event that a screen portion is not active for a current display after a preselected minimum amount of time, that screen portion is disabled because the power to that screen portion is selectively turned off.
