Display device and method for driving the same
The present invention discloses a display device and a driving method thereof. The display device comprises a display panel, a grating, a voltage generating unit, a touch sensing unit and a control unit. The grating comprises a first electrode and a second electrode having a p plurality of electrode blocks. The voltage generating unit provides first and second voltages to the first and second electrodes, respectively. The control unit controls the values of the first, second voltages such that the grating is transparent during the 2D display phase and functions well during the 3D display phase. During a touch phase, the electrode blocks serve as touch electrodes so as to provide a touch function together with the touch sensing unit. Since the second electrode is used during both the display phase and the touch phase, the display device has a reduced thickness, lower costs and enhanced transmittance.
