Abstract:
1. A fiber optic face plate stack for a display, the display comprising a light source, a transparent cover, a diffuser, and a brightness enhancement film, the fiber optic face plate stack comprising: a fiber optic face plate; wherein the fiber optic face plate is configured to allow light to be transmitted through the fiber optic face plate based on the light being incident on the fiber optic face plate within an angular region defined by an acceptance cone, the fiber optic face plate being configured to absorb light based on the light being incident on the fiber optic face plate outside the angular region defined by the acceptance cone; wherein the fiber optic face plate is biased at a specific angle by orienting fibers of the fiber optic face plate at a fiber angle equal to the specific angle with respect to a fiber optic face plate normal, the specific angle being between 1 and 80 degrees, wherein the acceptance cone has a central axis biased at the specific angle; and an image direction film between the light source and the fiber optic face plate and configured to offset distribution of the light according to the specific angle, wherein the image direction film changes an angle of transmission of the light through the image direction film, wherein the light from the light source is redirected into the acceptance cone, wherein the image direction film is configured to bias the light at the specific angle.
