Abstract: A polarizer, a polarizer array, a polarization-controllable method and apparatus, and an electronic device are disclosed. The polarizer includes multiple types of polarization units, each polarization unit includes a first liquid crystal cell and a second liquid crystal cell that are laminated, each liquid crystal cell includes a liquid crystal layer and an alignment film, and the alignment film is connected to an electrode layer configured to apply an external voltage to the liquid crystal layer. The first liquid crystal cell and the second liquid crystal cell of each polarization unit may be separately controlled as “connected” or “disconnected”, and orientations of alignment films of first liquid crystal cells between all the multiple types of polarization units are different. In a same polarization unit, when one liquid crystal cell is in an on state, emergent light of the polarization unit is polarized light in one polarization direction.
