Abstract
An optical display device comprises a light source, a pixelated display panel, and a light guide to collect light from the light source and to transport the light via total internal reflection. A first surface of the light guide includes recessed regions having a circular-based profile, such as a quarter-circle profile, to reflect the light from the light guide to the pixelated display panel. A first optical layer covering at least a portion of the first surface of the light guide fills the recessed regions included in the first surface of the light guide. A second optical layer covering at least a portion of a second surface of the light guide transmits the reflected light to the pixelated display panel.
