Abstract

提供了一种3DLED显示屏（41）及3D影像系统。3DLED显示屏（41）用于与主动式3D眼镜（42）配合使用，3DLED显示屏（41）上设置有起偏偏光层（412）,起偏偏光层（412）可对所有像素点（11）所发出的光统一进行起偏，由于起偏过程会吸收约一半的光效率，相当于显示屏用于显示2D影像时的屏幕亮度相对于像素点（11）的发光亮度减半，同时用于显示3D影像时的光效率计算基数也减半，这样在3D主动式眼镜（42）本身的光效率不变的情况下，从3DLED显示屏（41）发光到3D主动式眼镜（42）收光的整个过程的累计光效率会提升一倍。而用于显示2D影像时的屏幕亮度虽然减半，又可以从提高LED像素点（11）的原发光亮度来进行弥补，在兼顾平衡2D与3D显示模式时的亮度设计参数的同时，也提高了主动式3DLED显示的光效率。
