SYSTEM AND METHOD FOR CONTROLLING THE OPERATION PARAMETERS OF A DISPLAY IN RESPONSE TO CURRENT DRAW
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.

Another feature uses constricted convection to facilitate the cooling of the backlight assembly for the electronic display. Another feature uses an air curtain to further heat or cool the exterior viewing surface of the display. Another feature uses a linear polarizer with an insulating gap to reduce the solar loading of the display stack and provide insulation from the ambient air temperature. Another feature uses a fluid system to contact fluid coolant with the display surface in order to cool the display. Each of the features may be used alone, or in combination to provide the proper operating temperature for the display depending on its desired operating environment.
