【摘要】 本文在分析VGA图象显示原理和LED大屏幕与CRT视频图像同步显示原理的基础上，论述了一种显示效果较好、性能价格比高、电路上易于实现的方法——位平面寻址法实现多灰度图象，并详细分析了应用复杂可编程逻辑器件CPLD和在线可编程逻辑器件FPGA实现多灰度彩色LED大屏幕图像显示的原理及电路实现。更多还原

【Abstract】 In this paper , based on the study of VGA graphic displaying theory and the theory of synchronizing display between LED large-screen display system and CRT image , a method, Bit Plane Addressing Method which has good effect -. high ratio of performance to price and can be implemented easily in circuits is discussed. And the principle and the implementation of the multi-gray LED display system with programmable logic devices CPLD and FPGA are analyzed in detail.更多还原
