The Combined-virtual Pixels Technology for LED Display and Study of Algorithm
LED信息屏组合虚拟像素技术及其算法研究

A novel arrangement method of virtual-combined pixels is proposed for a dynamic image display effect. On the basis of traditional pixel arrangement, it adopts the control technique of pixel multiplexing, adjoining permutation, combination and virtual processing. The dynamic display with 1×M×N physical pixels will be the same demonstration effect as the dynamic display with 8×M×N physical pixels. A data algorithm and its logical structure are also presented. After processed by the algorithm, the original image data acquired by the computer can obtain the combination value of corresponding image pixels. Experiment shows that the data extraction and processing are real-time. Moreover the image bandwidth is reduced by 2/3 and the image demonstration effect is enhanced almost 8 times.
