摘要: By processing pixel data, a low-cost halftone method is proposed to improve viewing-angle characteristics of TN-mode TFTLCDs. The algorithm reduces the occurence pixels in natural images with mid-tone graylevels, preserving local luminance. improvement occurs some loss image detail. As density increased, pattern becomes less noticeable.
