Abstract
The present invention is a display assembly including: a display, a backlight module and a plurality of grills. The backlight module generates light rays for illuminating the display. The generated light rays exit the backlight module and are directed to a set of grills (ex.—Black Matrix substrates), which are configured between the backlight module and the display. The grills are configured for allowing a first portion of the light rays (ex.—light rays directed toward an eye position of a viewer of the display) to pass through the grills to the display, but are also configured for blocking a second portion of the light rays (ex.—light rays directed away from the viewer), thus preventing the second portion of light rays from reaching the display. The first portion of light rays are then received by and emitted from the display towards the eye position of the viewer.
