This invention pertains to the design and manufacture of large flat-panel electronic displays and, more particularly, to the manufacture of AMLCD type, flat-panel displays assembled in a single monolithic or monolithic-like assembly, strengthened for structural integrity, corrected for brightness and hue variations due to optical or electro-optical aberrations and structural non-uniformities, equipped with lighting means and optical means that provide large view angles while improving acuity and contrast, and thin film wiring in said display that is designed to avoid or compensate for non-uniformities in pixel response, brightness, and chromaticity. The present invention features techniques for designing large, robust monolithic and monolithic-like displays having good brightness and contrast over a wide range of viewing angles. These techniques include controlling the layout of the pixel array and its access circuits that modify the electrical characteristics in order to minimize undesirable optical, electro-optical, and ambient light aberrations and any electronic anomalies creating visually perceptible discontinuities or boundaries. These artifacts are reduced to levels that allow for better color correction. In addition, the use of optical components such as collimators, light enhancing films, diffusers, screens, polarizers and masks are described. The resulting displays present luminance and chromaticity outputs from areas of originally varying optical response that become uniform within the tolerances of the human visual system.
