Patent number: 7446736Abstract: A PDP having a driving circuit that reduces the reset voltage of the PDP driving waveforms to make it possible to use low-voltage elements and to achieve high contrasts is disclosed. Since conventional PDP waveforms require very high reset voltages, it causes a problem of intense background light emissions, low contrasts, use of high-voltage components, and increased circuit costs. According to the driving waveforms of the present invention, relative voltage differences between the address electrode and the X electrode and between the X electrode and the Y electrode are considered to design waveforms of low reset voltages, thereby providing high contrasts and low-cost circuit.Type: GrantFiled: February 25, 2005Date of Patent: November 4, 2008Assignee: Samsung SDI Co., Ltd.Inventors: Jeong-Hyun Seo, Joo-Yul Lee, Tae-Hyun Kim, Hee-Hwan Kim, Min-Sun Yoo
