Micro-optics for liquid crystal displays applications

Abstract—Micro-optics have become the key technology in liquid crystal display systems due to its capabilities of miniaturization and design flexibility. Design consideration and experimental re-sults of microoptical components for enhancing the image quality, providing better functions, increasing light efficiency, and gener-ating 3D images in liquid crystal display (LCD) applications are presented. Index Terms—Cholesteric, focusing foil, grooved lightguide, image-enhanced reflector, light control film, microlens array, micro-tube array, random grating, sub-wavelength grating, three-dimensional (3-D) display, transflective.
