Abstract:
Systems and methods for providing a display for an electronic device that includes a liquid crystal display panel assembly, a backlight assembly that includes a light source, and a spatially varying polarizer that provides phase retardation that varies as a function of propagation length away from the light source. The display may also include a linear polarizer and other optical components that improve the efficiency of the backlight assembly, thereby reducing power consumption, cost, space requirements, and provide other advantages.
