A multi-view 2D/3D switchable display utilizing a cylindrical liquid crystal lens array is proposed, featuring low operating voltage and fast response time. The display can switch between 2D and 3D modes, providing wider viewing angles and a thinner design compared to other similar devices.
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 moire pattern, and is much thinner compared to the other 2D/3D switchable display devices.
