Abstract
A non-uniform heating system is provided for liquid crystal displays. The system includes structure for applying a greater concentration of heat to the periphery of LCDs. Because mounting structures produce large heat sinks around the edges of LCDs, providing greater heat to the edges results in a more uniform distribution of heat across the LCDs. In another aspect of the heating system, rapid warming may be provided for preselected critical areas of a display to reduce warm-up time, reduce power consumption, and provide mission critical displays in situations such as scrambles of military aircraft on cold weather alert.
