VLSI visual display

DETAILED DESCRIPTION The present invention provides a visual display which comprises a miniature display compatible with VLSI technology to display thereon images having desired quality but are generally too small to be viewed by the naked eye and an optical system disposed in front of the miniature display for enlarging such images to be visible at the desired image quality.
The miniature display includes an array of display elements of sufficient resolution and a VLSI circuit monolithically integrated with the array for driving the display elements.
The VLSI circuit includes input terminals for providing electrical signals thereto to generate the images.
The VLSI circuit may further include a signal processing circuit or a microprocessor for processing signals applied through the input terminals to affect the displayed image.
In a preferred embodiment, the visual display includes a miniature display that is a liquid crystal display and the visual display further includes a light source for providing illumination to the liquid crystal display.
The liquid crystal display comprises a transparent cover positioned above the array of display elements, a transparent electrode deposited on the surface of the cover facing the array, and liquid crystal material such as dynamic scattering mode liquid crystal material disposed between the array and the transparent electrode.
In another preferred embodiment, a visual display with reduced image aliasing is provided.
The visual display includes a miniature display having an array of display elements with the positions of the display elements be displaced by small random distances from the positions of elements in a corresponding symmetrical array.
Preferably, the layout of the array is made with the use of a software silicon compiler program to determine the positions and the displacement of the display elements.
In another preferred embodiment, a visual display including a miniature display having an array of super-pixels, each comprising a central display element surrounded by a plurality of ancillary display elements
