摘要： A method and system implements a high addressability characteristic into an error diffusion process. A histogram of the image is generated and the actual background and black reference values are determined. A gray level value representing a pixel is received. The gray level value has a first resolution which corresponds to an original input resolution. The gray level value is interpolated to generate subpixel gray level values which correspond to a second resolution. The second resolution is higher than the first resolution and corresponds to the high addressability characteristic. A threshold circuit thresholds the interpolated gray level value and generates an error value as a result of the threshold using the determined background and black reference values. The error value has a resolution corresponding to the first resolution. A portion of the error value is diffused to adjacent pixels on a next scanline.

摘要： Aspects of the present invention are related to systems and methods for compressing display non-uniformity correction data and for using compressed display non-uniformity correction data. A correction image may be compressed by fitting a data model to the correction image data and encoding the model parameter values. A correction image may be decomposed into two images: an image containing the vertically and horizontally aligned structures of the correction image and a smoothly varying image. The smoothly varying image may be compressed by fitting a data model to the smoothly varying image data. Multiple correction images may be compressed by determining eigenvectors which describe the distribution of the multiple correction images. Projection coefficients may be determined by projecting each correction image the determined eigenvectors, and an eigen-image associated with an eigenvector may be compressed. Correction data for a display may be reconstructed from parameter values stored on a display system. A plurality of correction images may be reconstructed from encoded eigen-images stored on a display system.

摘要： A display device is provided that includes a plurality of pixels, where each pixel includes a single subpixel. In a first aspect, a single subpixel is able to sequentially generate a plurality of (e.g., at least three) primary colors. As a result of the single subpixel, the display is able to supply a gamut of colors including at least 3 primaries colors. For example, the sequential generation of the 3 primary colors may involve operating the subpixel in a time division multiplex (TDM) mode, and a primary combination color is supplied in response to the subpixel generating 2 primary colors in respective TDM subframes. When the pixel includes at least two neighboring subpixels, the pixel may additionally be operated in a spatial division multiple (SDM) mode or in the TDM mode.

摘要： A display system includes a building, a wall enclosed within the building, and a light guide directing light from the exterior of the building to the wall within the building. A display is supported proximate the wall where the display includes a liquid crystal layer and not including a backlight. The light guide directing the light to the liquid crystal layer is in such a manner that the combination of the light and the liquid crystal layer results in an image displayed thereon.
