    Abstract: A liquid crystal grating, a driving method thereof and a 3D display device are provided. The liquid crystal grating includes: a plurality of periodical grating units, wherein each of the periodical grating units includes a plurality of strip-like electrodes; a first primary driving circuitry configured to drive the plurality of strip-like electrodes, to form a light-shielding section and a light-transmitting section in each of the periodical grating units; at least one second primary driving circuitry configured to drive the plurality of strip-like electrodes, to form the light-shielding section and the light-transmitting section in each of the periodical grating units; and a control circuitry configured to select the first primary driving circuitry or the second primary driving circuitry to drive the strip-like electrodes in accordance with a distance between a user and the liquid crystal grating.
