LED大屏幕显示器的显示内容直接由显示数据反映,点阵显示数据地址存放和显示器显示内容存在着一定的对应关系,这种关系应用的好坏决定着控制逻辑实现的难易。通过从数据内存的映射地址结构分析构造数据存放方法,总结一大类点阵LED显示器的地址映射规律性,构建出一个通用控制模型即显示数据分区方法,帮助设计者快速理清显示数据的存放方法,使得控制逻辑设计变得简洁和易于实现。
The display content of the LED large screen display is directly reflected by the display data. There is a certain corresponding relationship between the dot matrix display data address storage and the display content of the display, and the application of this relationship determines the difficulty of the control logic implementation. By analyzing the structure of the data storage from the data memory address structure, summarize the address mapping regularity of a large class of dot-matrix LED displays and construct a common control model that shows the data partitioning method, to help designers quickly sort out the display data storage Method, making control logic design simple and easy to implement.
