Abstract
We propose a multi-view 2D/3D switchable display by using cylindrical liquid crystal (LC) lens array with a low operating voltage and fast response time. The cylindrical LC lens array is composed of three parts: the LC layer, a top-plane indium tin oxide (ITO) electrode, and bottom periodic strip ITO electrodes. In the voltage-off state, the cylindrical LC lens array is equivalent to a transparent glass substrate and the viewers can see a clear 2D image. In the 3D mode, the cylindrical LC lens array can be used as a cylindrical lens array under a suitable operating voltage. As a result, the 2D and 3D images can be switched according to the state of the cylindrical LC lens array. The experimental result shows that the 2D/3D switchable display with the cylindrical LC lens array has a wider viewing angle, has no moiré pattern, and is much thinner compared to the other 2D/3D switchable display devices.

Summary
The display quality and viewing effect of two-dimensional (2D) displays have almost achieved perfection. Various 2D/3D switchable displays based on an LC lens array have been investigated in recent years [16]; for example, there is the dynamic integral imaging (InIm) display using the electrically movable LC lens array [17], the 2D/3D switchable mobile display using the liquid crystal polymeric (LCP). Lens array film [18], and the dual-direction overdriving method for accelerating the 2D/3D switching time of the LC lens array on auto-stereoscopic display [19]. The 2D/3D switchable mobile display using a polarization-dependent switching LCP lens array film can realize the high-resolution 3D display, but the device needs an additional twisted nematic LC cell to control the polarization direction of light. The experimental result shows that the 2D/3D switchable display with the cylindrical LC lens array has a wider viewing angle, has no moiré pattern, and is much thinner compared to other 2D/3D
