介绍了平板显示器灰度级的优化扫描结构,阐明了子空间权值按位扫描的思想,即将全局平面分成多个不同的区域,分别按权值大小的不同排列顺序扫描,改变了常规的逐行、逐点重复写入的模式。在权值扫描的基础上,着重描述了3种不同的子空间划分策略(遍历搜索、对称权值迭代、遗传算法推导,和各自的推导方式以及相应的优缺点。 最后,对上述3 种方法以及常规逐行扫描方法进行了对比,结果表明,新的扫描策略大幅提高了扫描效率,降低了工作频率。

This paper introduces an optimal gray-scale scanning structure of flat panel display and clarifies the value of the sub-space strategy,which is dividing the whole plane into a number of different regions (sub-space),that ordered by the same weights sequences,separately scan them by the value of weight. Three different methods for the sub-space division strategy were proposed:traversal search,weight-symmetry iterate and genetic algorithm. The advantages and disadvantages of the three methods were compared with traditional methods,it can be found the new scanning strategy greatly increased the efficiency and reduced the operating frequency.
