| 摘 要： | 嵌入式设备的图形界面输出至投影仪、显示器时,常常需要进行数字信号到VGA信号的转换.由于时序的不同,直接进行模数转换会给图像造成较大的影响.使用FPGA和SDRAM对LCD信号按照VGA时序转换后,VGA信号的图像质量大大提高.文中对转换过程中的重点问题进行了分析,并给出了解决方案.

| Abstract: | Graphic display in embedded systems sometimes needs to be output to projector or PC monitor, since digital signals are used in embedded systems, a LCD-VGA signal transform is necessary. Because of the difference between timing sequences, direct AD transform reduces the VGA display quality greatly. If the timing sequence of VGA signal are rebuild with FPGA and SDRAM, display quality can be improved greatly. |
