Abstract:
1. A display device comprising: a display panel; a touch barrier panel disposed on the display panel, and comprising a plurality of upper electrodes, a plurality of lower electrodes, a liquid crystal layer disposed between the upper electrodes and the lower electrodes, a first polarizer, and a second polarizer, the touch barrier panel being operable both in a touch sensing mode and a 3-dimensional image display mode; and a touch barrier panel controller, wherein the plurality of upper electrodes are arranged in a first direction, and the plurality of lower electrodes are arranged in a second direction crossing the first direction, the plurality of upper electrodes are extended to cross the plurality of lower electrodes with the liquid crystal layer interposed therebetween, wherein the touch barrier panel controller is configured to apply voltages to the upper electrodes to operate in the 3-dimensional image display mode, and wherein the touch barrier panel controller is configured to apply voltages to one of the upper electrodes and the lower electrodes and detects a change in voltages of the other one of the upper electrodes and the lower electrodes to operate in the touch sensing mode.
