随着制造技术和工艺的突破，作为平板显示领域主导产品之一的LED显示屏无疑将获得更为广泛的应用。在工程实现中，LED显示屏的控制系统对整个系统的性能起着决定性的作用，而显示数据组织则是所有LED显示屏控制系统都必须要解决的关键问题。
鉴于显示数据组织这一问题的重要性，本文首先从多扫描线的角度对此进行了重点讨论。根据LED显示屏的工作特点提出了显示数据应按扫描输出顺序连续排列的组织原则；并按照不同显示方式的要求详细阐述了数据组织的流程，给出了反映显示信息与物理存储器之间映射关系的解析式，为输入输出操作实现数据寻址提供了准确的依据；在此基础上讨论了相应的输出算法。文中还对多扫描线数据组织方法的存储效率进行了分析并提出了降低存储空间占用的解决方案。由于多扫描线显示数据组织问题在平板显示技术中是具有一定的共性，因此本文所做的探讨也可供该领域的其它实现方案参考。
在分析多扫描线数据组织方法的基础上，介绍了结合课题的应用背景设计的可控制4096×256点阵大型LED显示屏的控制系统。通过对铁电单片机VRS51L3074的性能特点及其与显示屏控制需求的适应性分析，论证了以之作为显示屏控制卡核心器件的可行性与合理性。对VRS51L3074的资源分配、控制卡各组成部分进行了说明；分析了显示屏控制信号电路、非易失性存储电路、外部数据总线扩展等电路模块；详细阐述了以VRS51L3074为核心并结合外围逻辑设计实现的32位并行输出RAM的访问机制。同时也介绍了控制系统的软件结构以及设计中为进一步提高显示数据速度所采取的措施。
概括而言，本文主要对多扫描线显示数据组织的一般方法进行了探讨；介绍了以多扫描线数据组织方法为基础、通过恰当选择核心器件并采用合理的硬件结构和相应的指令优化等措施所设计的大型LED显示屏控制系统。

With the breakthrough in manufacturing technique, LED display panel, as one of the leading products in FPD(flat panel display), will be more widely used undoubtly. As far as a practical project is concerned, the whole panel system’s performance is mainly determined by its controlling system, while the display data organization is a key issue to each panel’s control system.
Considering the importance of data organizaton, a method is discussed emphatically in the sight of multiple scanning beam. A fundamental principle that data arranged continuously followed by scanning sequence is put forward, according to the panel’s operation mode. In accordance with the requirement of various display effects, the flow of organizing data is analyzed, the analytic expressions of mapping relationship between display area and memory is deduced, and corresponding algorithms are given. This provides credible fundation for data addressing. Storage efficiency of the method is also analyzed, and the solution for reducing memory space is given. Because data organization is a common problem existed in FPD, the method proposed in this thesis could serve a valuable reference for other implementation.
A control sysem based on above mentioned theory rearch is introduced,which could control a 4096×256 large-scale LED panel. By comparing with other devices and analyzing its suitability to the needs of LED panel control, the feasibility and rationality of VRS51L3074 serving as the core of the control card is proved. Components of the card and resource allocation of VRS51L3074 are discribed. The nonvolatile memory circuit, external data BUS extension circuit .etc, are analyzed. Coupled with peripheral circuits,  32-bit data could be output simultaneously from RAM to the panel with DMA mode. The method for accessing the data memory is introduced detailedly. This parallel mechanism provides an approach for high-speed data output. In the mean time, the structure of software and measures adopted to speed up data output significantly are also presented.
In summary, the emphasis of this thesis is focused on the universal method of multi-scanning beam display data organization. And the contol system designed for large-scale LED panels based on the method is intruduced.
