Abstract
According to one embodiment of the present invention, a method of power management for a flat panel display is disclosed. The method includes: receiving image data; determining a segment mode for the received image data; selecting a portion of the received image data corresponding to the determined segment mode; accumulating a value of the selected portion of the received image data; comparing the accumulated value to a threshold value; and generating an interrupt signal if the accumulated value exceeds the threshold value.
