摘　　要：将LED显示屏的特点和自由立体显示的视觉效果相结合,采用特殊的LED立体显示屏,利用片上系统(SoC)和可编程片上系统(SoPC)的设计方法,提出立体LED显示屏控制系统的完整设计方案。在LED时序发生器的设计中利用直接内存存取(DMA)传输技术,生成队画面数据,用改进型的D/T转换技术控制所有像素点的亮度。结果表明,本设计借用了立体液晶显示的解决方法,在LED显示屏上实现了自由立体显示,保证了屏幕的刷新速率,同时还降低了立体真彩显示系统的复杂性。该设计方案能够保证画面有效实时显示,具有较强的实用性。In this paper,a complete design of the stereoscopic LED display control system is developed based on System on Chip（SoC） and System on Programmable Chip（SoPC） technique using particular LED display screen.The design combines the property of LED display screen and the effect of auto-stereoscopic display.The Direct Memory Access（DMA） transmission method is used to generate the frame data,and the D/T conversion technique is utilized to control the brightness of all pixel points in the design of the LED time generator.Simulation results show that the proposed method can be used to realize the auto-stereoscopic display on the LED display screen,which could guarantee the refresh rate of the screen and decrease the complexity of the stereoscopic real color display system.Moreover,it is more practicable to accomplish the real-time display of the frame effectively.
