Estimating the term…
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.
A system for controlling the power consumption of an electronic display, the system comprising:
A method for controlling the power consumption of a system having a display backlight, a fan which is positioned so as to draw cooling air through an area of the display which requires cooling, a temperature sensor placed in the area which requires cooling, a display current draw measurement device, a maximum current value (Cmax), and a maximum temperature value (Tmax), the method comprising the steps of:
A method for controlling the power consumption of a display according to a maximum current value (Cmax)and a maximum temperature value (Tmax), the display having a backlight and a fan placed within an area of the display which requires cooling, the method comprising the steps of:
