Liquid crystal prism, method for driving the same, and display device
The present application provides a liquid crystal prism including a first substrate, a second substrate, a liquid crystal layer arranged between the first substrate and the second substrate, a face recognition circuit, a prism form determination circuit and a control circuit. The liquid crystal prism is divided into a plurality of prism units. The face recognition circuit is configured to acquire eye position information from one or more faces, and transmit the eye position information to the prism form determination circuit. The prism form determination circuit is configured to determine a prism form in accordance with a correspondence mapping table about correspondences between eye position information and prism forms, and the eye position information acquired by the face recognition circuit. The control circuit is configured to control voltages applied to the strip-like electrodes of the prism units in accordance with the prism form determined by the prism form determination circuit.
