摘要： The present invention provides a visual display including a high resolution miniature display compatible with VLSI technology and an optical system such as an optical magnifier used to enlarge the images display on the miniature display to be visible to the naked eye. The miniature display includes a VLSI backplane having an array of display elements monolithically formed with its driving circuit on a single crystalline semiconductor. Signal processing circuit or a microprocessor used to process image signals for the display may also be formed monolithically with the array and its driving circuit. The array may be designed using a software silicon compiler program to have randomly displaced elements or superpixels for reducing image aliasing. The array may also be designed to have display elements positioned and scaled to compensate for the optical distortion introduced by the magnifier. A color microdisplay utilizes diffraction gratings to provide an array of high efficiency color pixels. The microdisplay includes a semiconductor substrate and source of light disposed adjacent thereto. A cover plate may be disposed above the substrate and has a layer of conductive material on a surface of the cover plate opposite the substrate. An optically active material, such as liquid crystal material, may be disposed between the substrate and the cover plate. An array of pixels are formed on the substrate. The pixel array includes an array of diffraction grating elements. Each element includes one or more diffraction gratings. The pitch of each diffraction grating can be a function of the angle of the incident light and the desired diffraction output spectrum. An optical system directs the diffracted light from each grating through the optically active material into viewing optics.
