    摘要:DS3881和DS3882CCFL控制器,用于汽车,工业和航空电子应用背光液晶面板,需要高的调光比。这些CCFL控制器使用模拟灯电流的振幅调制和数字脉冲宽度的脉冲调光技术,以实现高的调光比。然而,数字PWM脉冲调光,可以创建可见闪烁调光在非常低的水平。本应用笔记介绍了如何消除闪烁。Maxim>AppNotes>AutomotiveDisplayDriversKeywords:CCFL,coldcathodefluorescentlamp,automotive,liquidcrystaldisplay,LCDJan28,2009APPLICATIONNOTE4092HowtoPreventFlickerCausedbyBurstDimmingAbstract:TheDS3881andDS3882CCFLcontrollersareusedinautomotive,industrial,andavionicapplicationstobacklightLCDpanelsthatrequireahighdimmingratio.TheseCCFLcontrollersusebothanaloglamp-currentamplitudemodulationanddigitalpulse-widthburst-dimmingtechniquestoachievethehighdimmingratio.ThedigitalPWMburstdimmingcan,however,createvisibleflickeratverylowdimminglevels.Thisapplicationnotedescribeshowtoeliminatetheflicker.IntroductionTheDS3881andDS3882CCFLcontrollersusebothanaloglamp-cur……
