Abstract
Light emitting panel assemblies include a sheet, film or plate overlying a light emitting member. The sheet, film or plate has a pattern of deformities on one or both sides that may vary or be random in size, shape or geometry, placement, index of refraction, density, angle, depth, height and type for controlling the light output distribution to suit a particular application. Also the sheet, film or plate may have a coating or surface treatment for causing the light to pass through a liquid crystal display with low loss.
