Abstract:
The embodiments of the present disclosure relate to a liquid crystal grating, a display device, and methods for controlling thereof. The liquid crystal grating comprises a first substrate; a second substrate disposed opposite to the first substrate; an electrode layer disposed on the first substrate or the second substrate, wherein the electrode layer comprises at least two sets of electrodes arranged periodically, and each set of electrodes of the two sets of electrodes comprises two sub-electrodes arranged parallel to each other; a liquid crystal layer disposed between the first substrate and the second substrate; and a control unit configured to make the liquid crystal grating be operated in a transparent mode or a grating mode; when the liquid crystal grating is operated in the transparent mode, there is no voltage difference between two sub-electrodes of each set of electrodes, and between two adjacent sub-electrodes of different sets; and when the liquid crystal grating is operated in the grating mode, there is a voltage difference between two sub-electrodes of each set of electrodes, and there is no voltage difference between two adjacent sub-electrodes of different sets. The embodiments of the present disclosure can increase the viewing angle of display device, and cancel the zero-order diffraction of light of different wavelengths.

Claim (Index 6):
The display device according to  claim 5 , wherein the display module is a liquid crystal display module, and the liquid crystal grating is located above an upper polarizer of the liquid crystal display module or between a lower polarizer and a backlight module thereof.
