Abstract:
1. A method of driving a polarization switch in a display apparatus comprising a display panel which alternately displays first viewing point images in a first period and second viewing point images in a second period in a time-divisional manner, and a polarization switch which provides the first viewing point images and the second viewing point images with different polarization directions from each other, the method comprising: applying a voltage to the polarization switch during an activation period in order for the first viewing point images to have a first polarization direction; and applying no voltage to the polarization switch or applying a bias voltage to the polarization switch during a relaxation period in order for the second viewing point images to have a second polarization direction different from the first polarization direction, wherein the activation period of the polarization switch is shorter than the relaxation period of the polarization switch, and the bias voltage is smaller than the applied voltage.
