| 摘 要： | 具备亮度校正功能的DVI-DVI处理器被应用到LED大屏幕显示,可以较好的解决工程上为了增加或升级亮度校正功能而更换显示控制系统的问题.但是DVI-DVI处理器的动态内存读取频率较低,不能发挥DVI双链路的数据传输性能.本文通过对动态内存中待读取的校正参量按照特定算法进行重组和压缩,将动态内存的等效读取频率从266MHz提高到330MHz,实现DVI双链路传输对超大分辨率的LED显示屏进行有效的亮度校正.

| Abstract: | DVI-DVI processor with brightness correction is applied to LED large screen display to resolve the problem of upgrading display control system.However,the DDR SDRAMfrequency of the DVI-DVI processor is so low that the data transmission per-formance of the DVI dual link can not be exploited.By reorganizing and compressing correction parameters,the equivalent fre-quency of DDR SDRAMis improved from 266MHz to 330MHz,and super resolution LED display is effectively corrected base on DVI dual link. |
