摘　　要：开发特殊液晶显示器驱动板,实现将VGA信号转换成符合液晶屏时序的数字信号的功能。该板由单片机、FPGA和其它器件组成。单片机测试输入信号的频率,以确定LCD的分辨率;设置FPGA和AD的寄存器,以控制它们工作。该板已通过高低温的实验测试,并投入使用。A LCD (liquid crystal display) drive board for the special uses was developed to realize the transformation from VGA signal to the digital signal according to the LCD time sequence. This board consists of a MCU (micro control unit), a FPGA (field programmed gate array) and other components. The MCU detects the frequencies of input signals to determine the resolution of LCD, and sets the registers of FPGA and AD (analog to digital conversion) to control their operations. The board was tested successfully by the low and high temperature experiments, and put into services.
