串扰是两条信号线之间的耦合、信号线之间的互感和互容引起线上的噪声。容性耦合引发耦合电流,而感性耦合引发耦合电压。PCB板层的参数、信号线间距、驱动端和接收端的电气特性及线端接方式对串扰都有一定的影响。随着科学技术的发展,计算机价格越来越低,性能越来越好,局域网的传输速度越来越快,局域网的传输介质也从同轴电缆转向了双绞线和光纤,双绞线从最初的CAT1、CAT3、CAT5发展到了CAT5E、CAT6、CAT6A、CAT7。
...信利裸眼3D显示萤幕的优势在于亮度、可视角度、串扰(CrossTalk)及云纹(莫尔效应)等光电参数皆领先业界。所谓的串扰(CrossTalk)是指在两条信号线之间的耦合现象。这是因为空间距离过近的信号线之间会出现不需要的电感性和电容性耦合,从而互相干扰。
