Abstract

A display component controls a viewing angle in a display system that achieves a strong private mode and enhanced brightness in the private and public modes as compared to conventional configurations. A display system that is operable in the private mode and the public mode includes the display component in combination with an image panel. The display component includes a backlight unit that emits light from a non-viewing side of the display component toward a viewing side of the display component; a barrier and slit structure located on a viewing side of the backlight unit, the barrier and slit structure comprising a plurality of opaque barrier regions interspersed with a plurality of transparent slit regions; and a lens array of lens elements located on a viewing side of the barrier and slit structure, with the lens elements being located in a separate plane relative to the barrier regions, wherein the barrier and slit structure and the lens array operate to transmit light from the backlight unit collimated in a limited viewing angle range.
