Abstract:
1. A method of controlling a 2-dimensional/3-dimensional (2D/3D) switchable display apparatus including a scanning backlight and a lenticular array, the backlight illuminating a display panel and including a plurality of light guide plates, a plurality of light sources disposed on the respective light guide plates, and a plurality of first polarization filters and a plurality of second polarization filters, and wherein a second polarization direction of the second polarization filters differs by 90° from a first polarization direction of the first polarization filters, the method comprising: turning on odd-numbered light sources of the backlight only at a frequency at which odd-numbered frames are inputted to the display panel, such that light having the first polarization direction is output from the backlight and transmitted to the lenticular array; turning on even-numbered light sources of the backlight only at a frequency at which even-numbered frames are inputted to the display panel, such that light having the second polarization direction is output from the backlight and transmitted to the lenticular array; and while input of the odd-numbered or even-numbered frames is repeatedly performed, repeatedly and alternately turning on the odd-numbered or even-numbered light sources; wherein each of the plurality of first polarization filters is merged with one of the odd-numbered light guide plates as one unit, combined on light emitting surfaces of the odd-numbered light guide plates and each of the plurality of second polarization filters is merged with one of the even-numbered light guide plates as one unit, combined on light emitting surfaces of the even-numbered light guide plates.
