A plasma display device, which gradually increases the current to the panel capacitors is disclosed. The display uses an inductor to reduce the current spike which would otherwise occur and create large electromagnetic interference.

Plasma display and driving method thereof

A driving apparatus of a plasma display is disclosed. The apparatus includes a first switch connected between a first power source for supplying a first voltage and a scan electrode, and a first diode and a second switch connected in series between a second power source for supplying a second voltage that is higher than the first voltage and the scan electrode. Further, the driving apparatus includes a third switch connected between a power recovery power source and a contact point between the first diode and the second switch, and a second diode connected in parallel the first diode and the third switch.

Plasma display and multi-current path driving apparatus thereof

A plasma display apparatus includes a plasma display panel (PDP), a chassis base secured on a first side to the PDP and having a driving circuit board mounted on a second side, a tower-shaped fixing unit that protrudes above the second side of the chassis base, and a back cover secured to a tower unit of the tower-shaped fixing unit to cover the driving circuit board.

Chassis base and plasma display apparatus having the same

A plasma display device and a method of driving the same, capable of reducing or preventing the deterioration of components such as a switching device, due to an overcurrent. In a reset period, in order to cause the voltage of a scan electrode to ramp down from a first voltage to a second voltage, a panel driver includes a falling ramp switch that repeats turn-on/turn-off operations, alternately coupling and de-coupling a low-level power supply to the scan electrode, resulting in a gradually falling ramp waveform. A switch controller generates a switching pulse to control the falling ramp switch. Each turn-on time of the switching pulse for the initial falling ramp waveform following a power-on of the plasma display device is controlled to be shorter than each turn-on time of the switching pulse for other falling ramp waveform.

Plasma display device and driving method thereof

Disclosed is an automatic power control (APC) method for a plasma display panel (PDP) including a plurality of address electrodes and a plurality of scan electrodes and sustain electrodes alternately arranged in pairs, which includes: calculating a load ratio change between current input data and previous input data; comparing the calculated load ratio change with a predetermined number of threshold values to determine to which area it belongs; determining a brightness control speed which is a time for applying a new brightness value matched with the determined area; and outputting sustain pulse information corresponding to a load ratio of current data at the determined brightness control speed. Also, the brightness control speed is shortened in the high gray, and it is lengthened in the low gray.
