The Combined-virtual Pixels Technology for LED Display and Study of Algorithm
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.
