LED信息屏组合虚拟像素技术及其算法研究

提出了一种新的LED信息屏像素排列技术——组合虚拟像素技术。在传统的动态信息屏像素排列的基础上，采用像素复用方式的控制技术，并对其进行临近组合排列和虚拟化处理，从而使1个具有M×N个物理像素的动态显示屏可以得到约8×M×N分辨率的显示效果。同时通过实验研究还提出了一种数据整合算法及其逻辑结构，它能将由计算机输出的图像原始数据，根据相应算法予以处理后，得到与屏幕上相对应像素的组合值。该处理是实时的，而且通过此算法处理后图像带宽减少了2/3，图像的显示效果提高了近8倍。

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.
