International Classification:

G02F 11339

US Classification:

349153, 349 73, 349 74

Abstract:

The present invention features designs of pixels and designs of control features for seals on AMLCD tiles optimized for tiling AMLCD flat panel displays (FPDs) which have visually imperceptible seams. The FPD structure has an image view plane which is continuous and remote from the pixel apertures or image source plane on the inside of the tiles. The image is formed on the view plane by a distributed ultra low magnification flies-eye optical system (a screen) that is integrated with the tiles, effectively excluding and obscuring an image of the seams. The innovations described herein minimize the defects on the perimeter pixels by effectively damming the waviness of the front of the seal near the perimeter pixels on the tiles. Dark space required for the seal between the interior tile edges and active regions of the pixels is decreased, as is the space allocated for wiring thereby increasing the feasible aperture ratios near the mosaic edges and all apertures. The tile designs make effective use of the area of an entire manufacturing panel.

International Classification:

G02F 1133

US Classification:

349 73, 349 42, 349 74

Abstract:

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.

International Classification:

G02F 113

US Classification:

379 95, 379 67, 379 69

Abstract:

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.
