Two path liquid crystal light valve color display with light coupling lens array disposed along the red-green light path

摘要: A full color, liquid crystal display device is disclosed having two optical paths, the first for long (red) and medium (green) wavelength regions of visible light spectrum, second short (blue) region spectrum. The paths their properties are nominally matched to characteristics chromatic luminance processing channels human visual system. two-path generates separate, spatially coherent color images using valve image forming sources, without use filters typically found in displays. combined by additive spatial superposition produce a single, full-spectrum, composite image. In one embodiment, individual red green components from an efficient, patterned backlight emitters coupled coupling lens array respective pixels valve. another form passing through aligned valves selecting polarizers. couples other. Suitable arrays both embodiments include SELFOC array, strip or microlens array. may be either directly viewed optically projected conventional projection assembly onto intermediate viewing surface.
