技术领域
本发明涉及LCD技术领域，特别涉及一种新型液晶调光遮阳板后视镜。

通过本发明的设计，将上置TN型液晶显示器和下置VA型液晶显示器一体化，(1)当上方TN型液晶显示器不工作、下方VA型液晶显示器工作时，利用VA型液晶显示器的好的透光作用，可以作为遮阳板使用，调节VA型液晶显示器的明暗可以在逆光中驾驶汽车，且不影响司机视线；(2)当上置的TN液晶显示器工作、下置的VA液晶显示器不工作时，由于反射式TN液晶显示器的反射效果，显示器又可以当后视镜使用，也可以作为司机的镜子用，方便司机上下车前，整理下仪容。VA产品的高对比度、外观形状尺寸个性化和TN反射型的完美结合，既达到了既美观又简洁实用的目的，也增添了汽车对司机和乘客的舒适度。
以上实施例在以本发明技术方案为前提下进行实施,给出了详细的实施方式和具体的操作过程,但本发明的保护范围不限于上述的实施例。上述实施例中所用方法如无特别说明均为常规方法。
