Automatic discrimination system for color unevenness in the picture on thin film transistor type of liquid crystal display adapted to the color sensation of dark eyes

摘要

The conventional color uneven detectors can detect the pixel defects in the picture on the thin-film transistor liquid crystal display (TFT-LCD), but can not discriminate the color unevenness in this picture. For the solution of the above-mentioned issue, the present study has developed a new automatic discrimination system for color unevenness adapted to dark eyes. The lower and upper limits of the subjective equivalent at the red color stimuli stored in the memory has converted by the 256 tones. The 256 tones used to the division of the red color stimuli is not the wavelengths but the chromaticness. The color unevenness in the picture on the TFT-LCD can be simply discriminated. Using this new automatic discrimination system for color unevenness in the production line, the work process of the color uneven discrimination in the picture on the TFT-LCD is simplified, while such work has been conducted by color sensations of factory workers up to date. Consequently, specialists need not to be employed and also the quality of the products can be employed without my specialist's intervention. Necessarily, the working efficiency is improved.
