Abstract: A double-layered liquid crystal lens in which two liquid crystal layers are disposed, and a 3D display apparatus. In a 3D display mode, under control of an electric field, liquid crystal molecules of a first liquid crystal layer are deflected to form a plurality of first lenticular lens structures. In case of switching from the 3D display mode into a 2D display mode, under the control of an electric field, liquid crystal molecules in a second liquid crystal layer are deflected to form a plurality of second lenticular lens structures; the second lenticular lens structures are mirror symmetric to the corresponding first lenticular lens structures, so as to compensate a phase delay of a light modulated by the first lenticular lens structures, such that the light passes through the double-layered liquid crystal lens without deflection, and thus a normal 2D display state is realized.
Abstract translation: 设置有两个液晶层的双层液晶透镜和3D显示装置。 在3D显示模式中，在电场的控制下，第一液晶层的液晶分子被偏转以形成多个第一双凸透镜结构。 在从3D显示模式切换到2D显示模式的情况下，在电场的控制下，第二液晶层中的液晶分子被偏转以形成多个第二双凸透镜结构; 第二双凸透镜结构与对应的第一双凸透镜结构镜像对称，以补偿由第一双凸透镜结构调制的光的相位延迟，使得光通过双层液晶透镜而不偏转， 从而实现正常的2D显示状态。
