Abstract
Official abstract text for this publication.
A display device comprising a display panel, a diffusing member positioned between the display panel and an observer, and a directional backlight wherein the directional backlight comprises a half angle divergence equal to or less than 15°. The display cover is preferably configured to shift an image displayed on the display panel relative to an observer to obscure a bezel surrounding the display panel. The use of a directional backlight and a diffusing display cover plate allows for a very small gap between the display panel and the display cover plate.
