Abstract
An electrical polarization filter, an electronic apparatus including the electrical polarization filter, and a method of operating the electronic apparatus are provided. The electrical polarization filter includes a liquid crystal panel configured to control a polarization angle of incident light and a polarization unit configured to display a linear polarization characteristic. The liquid crystal panel includes first and second transparent plates, first and second electrodes provided between the first transparent plate and the second transparent plate, and a liquid crystal layer provided between the first electrode and the second electrode, wherein the incident light directly enters one of the first and second transparent plate provided on an outer side. The polarization unit may be a passive type polarization unit or an active type polarization unit.
