Electro-optical characteristics of plasma display panel with Mg1-xSixO protecting thin films deposited by an electron-beam evaporation method

The effect of Si doping in MgO has been investigated in order to improve the material properties of the MgO protecting layer in plasma display panels. A small amount of Si was added to the MgO pellet while the MgO layer was being deposited by using an electron-beam evaporation method. Both the surface characteristics of the protecting layer and the electro-optical properties of 4 in. test panels were investigated, such as firing and sustain voltages, luminous efficacy, addressing jitter, and image sticking. The firing voltage is minimized when the Si concentration is 0.03%similar to 0.04%, where the luminous efficacy increases up to 35% compared with that of the conventional MgO film, and the boundary image sticking also shows good characteristics around the Si concentration level by 0.04%.
