Abstract

Specially designed backlight systems can cast information from display screen to designated zone. Here we introduce an ultra-thin multi-directional backlight system. The main components of the system include microlens arrays, a Fresnel lens and a high-brightness liquid crystal display (LCD) panel. The proposed backlight system allows us to control the light propagation in a desired manner, and could be applied to three dimensional (3D) display.
