摘要
Low-profile, large screen display using a rear projection array system using an array of micro projectors, each comprised of a micro-display device, several optical components, a red/green/blue light emitting diode light source, a light sensor for each color and power driving and interface electronics circuits. The plurality of Micro Projectors are arranged as an array along the vertices of a grid to conjointly project a uniform and seamless image comprised of the collective projected output pixels (sub-image) of the array of Micro Projectors. The Array Controller processes output signals generated by the light sensors embedded in each Micro Projector in the array and generates pixel gray scale input and light source control signals for each of the Micro Projectors in the array to maintain uniform luminance and chromaticity (color-point) across the array. Various features are disclosed. including tapering and diffusion of the sub-image boundaries to form a single large display.
