This invention pertains to the design and manufacture of large, flat-panel electronic displays and, more particularly, to the manufacture of active matrix liquid crystal display (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 visual acuity and contrast, and thin film wiring in the display that is uniquely designed to avoid or compensate for non-uniformities in pixel response, brightness, and chromaticity. The present invention features are series of techniques for designing and assembling of large, robust monolithic and monolithic-like flat panel displays. Many techniques originally developed for creating tiled, flat-panel displays having visually imperceptible seams may be advantageously applied to monolithic structures. These techniques include single-sided wiring, two-sided wiring from opposite sides, segmented row and column lines, and reordering row and column lines in fan-out region. Single-sided wiring facilitates the construction of displays with small outlines. By using these techniques, display sharpness and contrast may be improved. In addition, color and luminance balance and uniformity across the display may also be improved.
