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, fullcolor 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 grayscale 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 bination 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 design of LED display controller based on FPGA, need to choose what kind of software development tools, the design of LED display scan control program. This topic is Verilog language writing software part of the design is chosen. According to the characteristics of the Verilog language design and write programs are written rules bined with hardware circuit of LED display scan control part. So, this topic is designed by bining lattice screen to the internal structure of the analysis and understanding of the characteristics and properties, design the design scheme of LED display control circuit. Combining the FPGA development board, hardware circuit and software design, finally achieved the LED display control system design. Key words: FPGA 。 所以，本課題設(shè)計(jì)是通過結(jié)合點(diǎn)陣塊內(nèi)部結(jié)構(gòu)的特點(diǎn)和特性的分析和理解，設(shè)計(jì)出了對 LED 顯示屏控制電路的設(shè)計(jì)方案 。本課題設(shè)計(jì)選用的是 Verilog 語言編寫軟件部分。根據(jù) LED 顯示屏的特性和內(nèi)部組成結(jié)構(gòu)，選定需要用的驅(qū)動(dòng)控制芯片，設(shè)計(jì)一款該 LED 顯示屏的驅(qū)動(dòng)電路 。 本課題研究的是當(dāng)今行業(yè)流行的雙基色 LED 顯示屏驅(qū)動(dòng)控制器技術(shù)，以 FPGA 為核心結(jié)合顯示屏控制電路驅(qū)動(dòng)點(diǎn)陣屏。例如：手機(jī)屏、筆記本電腦顯示屏、廣告牌、數(shù)碼相機(jī)、大屏電視機(jī)以及軍事領(lǐng)域等等都有應(yīng)用，因而得到了業(yè)界廣泛的關(guān)注。 編號： 桂林電子科技大學(xué)信息科技學(xué)院 畢業(yè)設(shè)計(jì) (論文 )說明書 題 目： 基于 FPGA 的彩色點(diǎn)陣控制器設(shè)計(jì) 系 別： 電子工程系 專 業(yè)：
