Abstract
Embodiments are disclosed for a method for controlling backlighting of a heads up display of a vehicle. In one example, the method includes adjusting different backlighting regions of the heads up display differently without analyzing a displayed image. In another example, different backlighting regions include a first region and a second region that do not overlap, and adjusting is based on a vehicle operating parameter, user input, and/or a vehicle mode. In another example, backlighting is controlled via a backlight with an array of light emitting elements, and regions include separate adjacent groups of light emitting elements.
