Abstract
A system and method for controlling the power consumption of an electronic display. A maximum current value may be selected where above this value the risk to damage to the display or local circuitry may be jeopardized. Ramp-wise and/or gradual controls of the display parameters such as fan speed and backlight levels may reduce the current draw during extreme situations and line voltage fluctuations. Embodiments allow the display to continue operation without risking an overload of the local circuit or damage to the display. Further embodiments may be used to limit the power consumption of a display in order to minimize energy usage. Several parameters can be measured and controlled simultaneously to provide a minimal amount of energy usage while minimizing any noticeable difference in images.
