Abstract
The present disclosure provides a grating structure, a display device and a display mode switching method. The grating structure includes a light-entering surface, a light-exiting surface, and a plurality of grating units arranged continuously between the light-entering surface and the light-exiting surface. Each grating unit includes: an accommodation chamber; a non-transparent electronic ink received in the accommodation chamber and having a predetermined electric polarity; and a controlling module arranged at a periphery of the accommodation chamber and configured to control a region of the electronic ink in the accommodation chamber. When an electric signal is applied by the controlling module, the electronic ink moves to a corresponding region in the accommodation chamber, and after the electric signal is cancelled by the controlling module, the electronic ink is maintained at the current region. The grating structure supports the switching between 2D and 3D display modes and reduces the power consumption.
