编号： 桂林电子科技大学信息科技学院 毕业设计(论文)说明书 题 目：基于FPGA的彩色点阵控制器设计 摘 要 LED显示屏工艺发展很快，使得LED显示屏有很多优异特性。由于其优异的特性，在生活应用很广泛。例如：手机屏、笔记本电脑显示屏、广告牌、数码相机、大屏电视机以及军事领域等等都有应用，因而得到了业界广泛的关注。LED 发展到现在，已经从最初的单色屏发展到现在的全彩显示屏，而且随着LED工艺制作技术发展，从以前的单个LED灯到现在的大屏的LED显示屏，从最早的无灰阶单色屏静态驱动，到现在彩色显示屏动态驱动，所以对驱动控制电路有了更高的要求。 本课题研究的是当今行业流行的双基色LED显示屏驱动控制器技术，以FPGA为核心结合显示屏控制电路驱动点阵屏。设计采用的FPGA芯片是目前较为流行的Altera FPGA系列为EP2C5T144C8N芯片。根据LED显示屏的特性和内部组成结构，选定需要用的驱动控制芯片，设计一款该LED显示屏的驱动电路。本课题设计的是基于FPGA的LED显示屏控制器设计，需要选用什么样的软件开发工具，设计LED显示屏的扫描控制程序。本课题设计选用的是Verilog语言编写软件部分。结合Verilog 语言设计的特点和编写程序的规则再结合硬件电路编写对LED显示屏的扫描控制部分。 所以，本课题设计是通过结合点阵块内部结构的特点和特性的分析和理解，设计出了对LED显示屏控制电路的设计方案。结合FPGA开发板、硬件电路和软件工程设计，最终实现了对LED显示屏的控制系统的设计。 关键词：FPGA；双基色LED显示屏；Verilog 语言 Abstract LED display technology developing rapidly, making the LED display has many excellent properties. Because of its excellent properties, is widely applied in life. For example, mobile phone screen, notebook screen, billboards, digital camera, a big TV and etc are used in the military field, thus gets widely attention. LED development up to now, already from the original monochrome screen development up to now, full-color display, and with the development of LED technology of the production process, from the previous single LED lights to the LED display screen now, from the earliest of gray-scale monochrome screen static drive, color display dynamic drive till now, so is the higher requirement for the drive control circuit. This topic research is the industry popular technology, dual color LED display driver controller with FPGA as the core in combination with lattice screen display control circuit drive. This topic design USES the FPGA chip is currently more popular Altera FPGA series for EP2C5T144C8N chip. According to the characteristics of LED display and internal structure, need to use the selected drive control chip, and design a driving circuit of the LED display. This topic design is de
