| 摘 要： | LED驱动芯片的动态响应特性经常被忽略，但却是相当重要的一个特性。动态响应影响LED显示屏的影像质量，如灰阶、线性度、EMI、信赖性。虽然这些特性彼此间有取舍关系．但是好的驱动芯片应该能够在这些特性中取得较佳的平衡。本文将探讨动态响应的重要性及LED驱动芯片与电路板设计技术，以协助工程师设计出影像质量良好的显示屏。

| Abstract: | AC responses of LED drivers are critical but usually ignored in LED display applications．AC responses affect the major performance of LED display panels，such as grayscales， linearity， EMI， and reliability． Although there is trade-off w ithin these requirements， LED drivers can provide balance．This article will further explain the importance of the AC responses of LED drivers and PCB design techniques to help engineers to design LED panels with good grayscale images． |
