Abstract: A smart film apparatus includes a smart film and a control member. The smart film includes a polymer dispersed liquid crystal or a polymer network dispersed liquid crystal between two conductive layers. Plural electrodes are formed on a single surface of one of the conductive layers, and it is easier to process. Two conductive layers that respectively include multitudes electrically isolated conductive units. With floating or ground controlling signal, the control member controls the conductive units to perform a variety of displaying effects. Moreover, the surface opposed to the single surface with electrodes is evenly flat with paste and beneficial to apply to desired target surface.
