Abstract
A liquid crystal display arrangement for a motor vehicle includes a plurality of light emitting diodes positioned to backlight a liquid crystal display. A plurality of electrical conductors are each electrically connected to, and provide electrical power to, a different respective subset of the light emitting diodes. An electronic controller is electrically coupled to each of the conductors and individually controls conduction of electricity through each of the conductors to thereby change a brightness of at least one of the subsets of the light emitting diodes relative to a brightness of at least one other subset of the light emitting diodes during operation of the motor vehicle.
