Abstract
The described embodiments relate generally to liquid crystal displays (LCDs) and more particularly to thermal management of heat produced by an illumination source in an LCD module. High temperatures generated by the illumination source can cause color shifts in the LCD due to changes in any included LEDs and liquid crystals. One solution is to house the LCD module in a metal chassis and thermally couple the LED light bar to the metal chassis. Furthermore, the LCD module can be kept at a uniform temperature by transferring heat from a region near the LED light bar to a relatively cooler region of the LCD module. These approaches can minimize any alterations or shifts in color resulting from heat from the LED light bar.
