Abstract
Disclosed herein are an optical shutter for a plasma display panel and driving method thereof. According to the present invention, an optical shutter, which employs a black organic solution that moves according to the electrowetting phenomenon and a pair of electrodes for providing voltages, is disposed on a display surface of the plasma display panel. In this state, during the non-display period, voltages are not applied to the optical shutter so that light emitted from the panel cannot transmit the optical shutter. During the display period, voltages having a different polarity are applied to the electrodes of the optical shutter so that light emitted from the panel can transmit the optical shutter. It is thus possible to completely prevent weak emission generating during the non-display period where cells are initialized and selected. Accordingly, there are effects in that contrast can be improved and the picture quality can be thus enhanced.
