Abstract
Regarding the problem of display nonuniformity under low gray level, experiments were designed to improve the display defect based on the luminance correction method of image processing.Based on high definition and super dark brightness CCD collector, the luminance information and Gamma curve data of each pixel of the liquid crystal display under low gray level were acquired, thus correcting the pixels one by one.The paper emphasizes on the introduction of the advantages of this acquisition system compared with others as well as the algorithm of brightness and cloud pattern correction.The experiment result indicates that the acquisition system can collect the brightness information of all pixels at a time, and can distinguish the luminance variety of each pixel effectively.The uniformity can be increased up to 100% theoretically.Under normal display condition, it can correct each frame of the picture independently in real time, ensuring the authenticity of the display information.关键词
