A dielectric sheet having two layers made of different materials for forming a differential dielectric sheet on a plasma display panel, a plasma display panel using the same, and a manufacturing method therefor.

Dielectric sheet, plasma display panel using the same, and manufacturing method therefor

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.

Optical shutter for plasma display panel and driving method thereof

A glass composition for a plasma display panel (PDP) and its fabrication method are disclosed. The composition, including a ZnO&#x2014;BOgroup and alkaline earth metal oxide, is environment-friendly, has a high discharge efficiency and is used as various PDP dielectric materials. The fabrication method allows to compose the low melting point unleaded non-alkali glass composition at a low cost.
