Abstract
A system for powering and controlling an LED-backlit liquid crystal display (LCD) where redundancy is used to provide two independent paths from a pair of power supplies to the LED backlight. Further, two independent paths are also used from a pair of power supplies to the LCD. If any one of the paths were to fail or begin to degrade in performance, the system contains monitoring circuits which can direct another path to be used by the system. Two separate control circuits for the LCD may be used so that either one may be used to control the LCD if one were to fail. Two separate temperature sensors and luminance sensors may also be used to increase the durability of the system.
