Patent number: 8179342Abstract: Provided are a method and apparatus for driving a PDP for widening a driving margin and improving contrast. The method for driving a PDP includes a first step of forming wall charges in cells with a set-up discharge using a set-up signal in a first sub-field and erasing the wall charges with a set-down discharge using a first set-down signal to initialize the cells, and a second step of erasing the wall charges with a set-down discharge generated using a second set-down signal different from the first set-down signal in a second sub-field, to initialize the cells. The method and apparatus for driving a PDP uniformly initialize sub-fields to widen the driving margin of PDP and remove a set-up discharge in at least one sub-field to improve the contrast of PDP.Type: GrantFiled: February 27, 2009Date of Patent: May 15, 2012Assignee: LG Electronics Inc.Inventors: Hee Jae Kim, Chang Young Kwon, Jeong Pil Choi, Seong Ho Kang

Patent number: 7999762Abstract: The present invention relates to a plasma display apparatus and driving method of the same. Since wall charges are remained without performing an additional erasing discharge after the sustain period is terminated and before the initiation of the reset period, the set up discharge can be generated with a small voltage during the reset period to obtain the margin of the driving voltage. In particular, since the highest voltage of the reset period during other subfields is lower than the highest voltage of the reset period of a subfield implementing a low gray scale, with inducing the half discharge before the set up discharge in other subfields, the set up discharge can be generated with a low voltage to improve the contrast due to the luminous output reduction.Type: GrantFiled: September 27, 2006Date of Patent: August 16, 2011Assignee: LG Electronics Inc.Inventors: Moon Shick Chung, Young Seop Moon, Chang Young Kwon

Patent number: 7990340Abstract: The present invention relates to a plasma display apparatus including a sustain driving apparatus that supplies a sustain signal to a panel. The plasma display apparatus includes a panel in which a front substrate having formed first and second electrodes therein and a rear substrate are coalesced, a sustain driver including a first switch for applying a first voltage to any one of the first and second electrodes and a second switch for applying a second voltage, and a circuit protection unit that controls one of the first and second switches, which has a voltage higher than a predetermined voltage, at its both ends, not to turn on. According to the present invention, when a voltage at both ends of the switch included in the sustain driving apparatus in order to supply the sustain signal is higher than a reference voltage, the switch is controlled not to turn on.Type: GrantFiled: November 8, 2006Date of Patent: August 2, 2011Assignee: LG Electronics Inc.Inventors: Hyun Il Park, Chang Young Kwon, Yun Kwon Jung, Jong Sik Lim, Kyu Choon Cho, Yang Ki An
