利用VGA卡实现LED大屏幕显示系统的同步
VGA Synchronous Technology of Large LED Display System
摘要
LED大屏幕显示系统采用的是一种数字显示技术,需要外部提供驱动数字视频源,而VGA卡连接的是模拟监视器,从VGA显示卡上无法取得数字视频信号,本文分析了从VGA卡上取得数字信号来实现LED大屏幕与VGA同步显示的技术.
Abstract
Digital display technology is used in large LED screen display system,which needs driving by external video frequency signal source,but it couldn't get from VGA card. This article introduces the technology of realizing LED synchronize with VGA by digital signal obtained from VGA card.
