摘要

根据LED虚拟显示屏的要求和特点

利用片上系统和可编程片上系统的设计方法

提出LED虚拟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专门提出了一种改进型的D/T 转换技术

无需任何预先数据处理

只用一个函数控制所有像素点的亮度。结果表明

设计方案解决了LED虚拟显示屏由于像素分时复用而带来的控制系统速度要求提高的问题

保证了屏幕的刷新速率

同时还降低了真彩显示系统的复杂性

能够保证画面的有效实时显示

具有较强的实用性。

Abstract

A complete design of the virtual LED display control system was proposed according to the special request and the characteristic of LED virtual display monitor

and by using the design method of the system on chip (SOC) and the programmable system on chip (SOPC). This paper proposed specially one kind of improved D/T transformation technology in the LED sequence generators design. It does not need any data processing in advance

only uses a function to control the brightness of all pixel likely. The result indicated that this design has solved the problem of high-speed requirement for the control system

which is caused by the pixel time division multiplex access(TDMA) in the LED virtual display panel

guaranteed the displayers refreshing speed

meanwhile reduced the real color display systems complexity. This design proposal can guarantee that the picture displays effectively and in real-time

and has the strong usability.
