Abstract
In a plasma display module, the cost and size of a power supply circuit are reduced. A plasma display module comprising a plasma display panel (1) having an address electrode, which selects the address of a display pixel, a Y-electrode, which selects a display pixel, and an X-electrode which applies the sustain discharge voltage of a selected pixel; an address electrode drive circuit (4); a Y-electrode drive circuit (2); an X-electrode drive circuit (3); a control circuit (5); and a power supply circuit (6); wherein the power supply circuit (6) includes, between a discharge sustain voltage line (Vs) and a ground (G), an electric field capacitor (61) and an electric double-layer capacitor (62) the capacitance of which can accumulate a charge that is 20 or more times the discharge current of one frame, and wherein each of the Y-electrode and X-electrode drive circuits (2,3) includes, between the discharge sustain voltage line (Vs) and the ground (G), a film capacitor (Cf), a ceramic capacitor (not shown) and/or an electric field capacitor (Cd) used for flowing a high frequency current.
