发明名称 METHOD FOR COOLING A LAMP BACKLIGHTING MODULE OF A LIQUID CRYSTAL DISPLAY
摘要 The present invention is a method for cooling a lamp backlighting module of a liquid crystal display. A preferred method of the present invention begins by providing a predetermined power input to a lamp. As power is provided to the lamp, the temperature of the lamp is monitored. When the temperature of the lamp rises to a first predetermined temperature, one or more fans are turned on which are adapted to dissipate the heat generated by the lamp. After the fan(s) cool the lamp to a second, lower predetermined temperature, the fan(s) are turned off. By using a fan to dissipate heat generated by a lamp backlighting module, the present invention may maintain the temperature of the lamp within a desired range. As a result, the present invention preferably increases the reliability and performance of the liquid crystal display. In particular, a preferred embodiment of the present invention minimizes the power necessary to achieve optimal luminance, and it enables the lamp to constantly produce optimal luminance for a constant power input.
