Abstract

The present invention discloses a plasma display device and its driving method comprising a step of recovering energy from the sweeping electrode to the first energy recovering circuit; a step of supplying the energy recovered from the first energy recovering circuit to the maintaining electrode; a step of recovering energy from the maintaining electrode to the second energy recovering circuit; a step of supplying the energy recovered from the second energy recovering circuit to the sweeping electrode. In the present invention, the first energy recovering circuit recovers energy from the sweeping electrode, and then supplies the energy recovered from the sweeping electrode to the maintaining electrode; the second energy recovering circuit recovers energy from the maintaining electrode, and then supplies the energy recovered from the maintaining electrode to the sweeping electrode.

Description

1. Technical field [0001] The present invention relates to a plasma display device and a driving method thereof, more specifically, a plasma display device and a driving method thereof which improve the efficiency of a driving circuit and reduce power consumption. 2. Background technology [0002] In recent years, various flat panel display devices capable of reducing the weight and volume of a cathode ray tube (CRT) have been developed. Such flat display devices include liquid crystal display (Liquid Crystal Display: LCD), field emission display (Field Emission Display: FED), plasma display panel (Plasma Display Panel: hereinafter referred to as "PDP") and electroluminescence Display (Electro-Luminescence: EL) and the like. Among them, the PDP is a display element utilizing gas discharge, and its large display panel is relatively easy to manufacture. Currently, most PDPs use a three-electrode AC surface discharge PDP in which scan electrodes and sustain electrodes are for...
