Publication number: 20080224958Abstract: In a plasma display device and a driving apparatus thereof, a scan electrode driver for applying a driving voltage to a scan electrode has a diode including a cathode coupled to a sustain voltage supplying power and an anode coupled to a switch for applying a reset rising waveform to the scan electrode. In the scan electrode driver, when a switch for applying a reset rising waveform is turned on, the voltage at the scan electrode is gradually increased by a voltage that is less than the sustain voltage due to the breakdown voltage of the diode. Therefore, the number of power sources is reduced simplifying the circuit configuration and reducing the plasma display device production cost.Type: ApplicationFiled: December 19, 2007Publication date: September 18, 2008Applicant: Samsung SDI Co., Ltd.Inventors: Kazuhiro ITO, Kyong-Pil JIN, Bong-Eun YOON, Tae-Wook KIM, Myoung-Kyu LEE
