Abstract
A high brightness, high color saturation liquid crystal display permits direct sunlight viewing. The display includes one or more diffractive color separation microlenses, in one embodiment, trimodal, which serves both to spatially separate incoming white light into red, green and blue bands and to focus the bands onto a subpixel matrix. A stepped and segmented surface of at least one microlens enables that microlens to provide a plurality of diffraction patterns.
