Abstract
A flat panel display incorporates an array of color separation microlenses. Each color separation microlens in the array is a single, micro-optical element which disperses color by orders to distinct color spots and focuses these color spots to related liquid crystal sub-pixels located in a common plane. Substantially all of the areas of the color spots fall directly and only on the liquid crystal sub-pixels. Little, if any, light energy is lost by falling outside areas occupied by the individual liquid crystal sub-pixels. Because the color separation microlenses provide the color separation, no color filter is required in the flat panel display. Eliminating the color filters eliminates light losses which are incurred when transmitting light through a color filter. The flat panel display makes more efficient use of light transmitted through the components of the display than was possible with prior art flat panel displays.
