Abstract
本申请公开了一种3D眼镜及3D影像显示系统，涉及显示技术领域，该3D眼镜的左眼镜片和右眼镜片均包括二分之一波长液晶盒和位于二分之一波长液晶盒靠近观看者眼睛一侧的第一圆偏光片，显示屏发出的圆偏振光透过左眼镜片和右眼镜片的二分之一波长液晶盒后，由于左眼镜片和右眼镜片的二分之一液晶盒可产生π相位延迟或不产生相位延迟，从而形成旋向相同或相反的圆偏振光，再结合左眼镜片和右眼镜片的第一圆偏光片中第一线偏振层的偏振方向和第一四分之一波长补偿层的慢轴方向之间的夹角的设置，使得光线快速交替地透过左眼镜片和右眼镜片，被观看者的左眼和右眼接收，实现3D显示效果，该3D眼镜具有结构简单、全视角且高通过率的优点。
