| 20080211743 | Plasma display device and driving method of plasma display panel - A driving method of a plasma display panel including a plurality of first electrodes, a plurality of second electrodes, and a plurality of third electrodes formed in a direction to be intersected with the first electrodes and the second electrodes is disclosed. The method includes resetting the electrodes by applying a waveform having a predetermined voltage to the first electrode, applying a fourth voltage to the second electrodes for a predetermined period; selecting cells to be discharged by applying a scan pulse voltage to each of the first electrodes and the third electrodes; and alternately applying a plurality of sustain discharge pulses having a first voltage as peak value to each of the first electrodes and the second electrodes, wherein the step of applying the fourth voltage Ve stops the application of the fourth voltage Ve while the first sustain discharge pulse of the first electrodes continues. | 09-04-2008 |
| 20090033232 | PLASMA DISPLAY AND VOLTAGE GENERATOR THEREOF - A plasma display device including a plasma display panel (PDP), a temperature detector for detecting temperature of the PDP, a driver for applying a driving voltage to a scan electrode, and a controller for generating a control signal to control the driver according to the temperature. The driver includes a transistor and first and second resistors. The transistor is coupled between a first power source and the scan electrode. The first power source supplies a scan voltage to the scan electrode. At least one of the first resistor and the second resistor is a variable resistor having a resistance that varies according to the control signal of the controller. A low discharge due to high temperature can be reduced or prevented, and the number of power sources of the plasma display device can be reduced. | 02-05-2009 |

A voltage of the plurality of output terminals may be a voltage of one the plurality of voltage terminals at least based on a level of a control signal transmitted to the first control signal input terminal. The logic element may be adapted to perform an operation on the control signal to generate a second control signal to be applied to the second control signal input terminal. The scan integrated circuit may establish a voltage of the plurality of output terminals to be a voltage of the first or second voltage terminal based on a level of the control signal. | 05-21-2009 |
| 20090174627 | PLASMA DISPLAY AND DRIVING DEVICE AND METHOD THEREOF - A plasma display, a driver for the plasma display, and a driving method thereof apply a reset minimum voltage according to a detected temperature of the plasma display. In the driving method, a reset falling waveform gradually decreasing to a reset minimum voltage is applied to a scan electrode during a falling period of a reset period, and a scan voltage is applied to the scan electrode selected during an address period. An address period is started the voltage applied to the scan electrode reaches the reset minimum voltage. In addition, a voltage difference between the reset minimum voltage and the scan voltage is determined according to a temperature of the plasma display. | 07-09-2009 |
