Abstract

Various embodiments of the present invention are directed to power-management methods for preventing needless dissipation of stored energy in operation of display components of electronic appliances, as well as for moving functionality from separately controlled and powered devices to a main display component in order to avoid unnecessary hardware, firmware, and software design and manufacturing complexities. In one embodiment of the present invention, techniques are applied in an electronic, information-displaying appliance using an organic-light-emitting-diode-based display component to increase the proportion of the display screen that appears dark, and that is therefore not emitting light, in order to decrease power consumption by the display component.
