Display backlighting apparatus

摘要

An image illumination apparatus for backlighting a portion of a liquid crystal display. The apparatus includes a light source generating an illuminating light, a light shielding medium located between the light source and a display grid, and an aperture formed in the light shielding medium for allowing the transmission of light generated by the light source to pass to a lighted portion of the display grid. The light shielding medium prevents light from being transmitted to a non-lighted portion of the display grid.
