Abstract
Methods and systems relating generally to information displays, and more particularly to systems and methods for backlight assemblies for information displays that emit an angularly narrow cone of light. A backlight assembly that emits a narrow angular cone of light can be particularly beneficial in a head-mounted display configuration, such as for use as part of virtual reality or augmented reality systems, where the head-mounted display comprises a lens assembly that directs light from an information display to the eyes of the user. Such a backlight assembly configuration may help reduce undesirable visual effects like flood illumination, ghost images, glare, and scattering.
