摘　　要：为了适应输入、输出显示信号的多样化,扩大显示屏的实用性,本文提出了一种基于FPGA的多模式显示驱动电路设计方案。利用FPGA对输入信号进行转换,同时嵌入自行设计的I2C总线模块,实现了兼容接收VGA、DVI和多种电视信号,并可以支持多种显示屏的显示。To meet the requirement of the diversity of display interface, a new digital controlling scheme was developed to improve the applications of the display panel. This controller not only can deal with the DVI, VGA and TV signals, but also can support a flexible output interface. Meanwhile, an I2C bus was inserted in the FPGA to complete the communication with the other outside chips conveniently.
