Abstract
The present disclosure relates to the field of display technology. In particular, a polarization switching device, a display apparatus comprising such a device, and a driving method for such a device are disclosed. Thereby, problems are solved, such as a reduced user experience due to the existing display apparatus incapable of switching the viewing angle range. By disposing the first and second conductive layers in the confined space of such a device, and controlling voltages for the first and second conductive layers, this application can change the size and the direction of the electric field in the confined space. As such, the long axis of the one-dimensional nanometer conductive material located in the confined space can be arranged along the direction of the electric field, so as to form a grating.
