Abstract Liquid crystal lens has the characteristic of variable focal length. Many studies have demonstrated that electronically controlled focusing without mechanical movements can be realized by using liquid crystal lenses in imaging system. In this paper, a four-electrodes liquid crystal lens with a rectangular aperture is applied to focus. The aperture’s aspect ratio of the liquid crystal lens can be designed arbitrarily so that installing it with the periscope lens in phones becomes possible.

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.
