随着LED行业技术的不断革新，LED显示屏的品质要求越来越高，为提高市场竞争力，各厂商逐步推出更高品质的产品。而在现有的众多LED控制系统中，为提高模组色彩均匀度和刷新率，而或多或少地在屏幕中留下了垂直拖影的病根。本文将根据理论分析和试验而得的垂直拖影与刷新率成正比而与色彩均匀度成反比关系为基础，提出一种新的扫描模式--以一种动态可调节的扫描方式来达到两个比例对象的均衡点，使其得到最佳的显示效果，测试结果表明本方案达到了预期设计目标。

With the innovation of LED technology, LED display is required to have higher and higher quality. In order to improve market competitive, many manufacturers push new LED display with higher quality. However, to improve the color uniformity and refresh rate in current LED controller system, there is "vertical Streaking" more or less in the LED display. Based on the theoretical analysis and test of vertical streaking and refresh rate direct proportionate to the relationship, but inverse proportion relation between vertical streaking and color uniformity, this paper is to raise a new dynamic and adjustable scan mode to realize the balance between them, to reach the best viewing. The test result manifests the expected design goal.
