20090066609 | METHOD AND APPARATUS FOR DRIVING PLASMA DISPLAY - A method and an apparatus for driving a plasma display in which supply of a driving waveform to the non-lighting display line of a plasma display screen is stopped while preventing level difference in luminance or instability of operational margin incident to stoppage of driving waveform supply. In the inventive plasma display, a sustain waveform is created and supplied to each display line of the plasma display, and supply of the sustain waveform is stopped for such a display line as no cell is lighted at all in a unit of sub-field thus quickening the clamp period of sustain waveform by using an inductance having an increased L value and shortening the sustain cycle. | 03-12-2009 |
20090079726 | PLASMA DISPLAY DRIVING METHOD AND APPARATUS - A plasma display driving method and apparatus that can reduce the occurrences of dropout, on a displayed image, caused by misaddress when the environment temperature becomes low. In the inventive plasma display, the environment temperature is determined, and during a charge adjustment interval, the ultimate voltage, which the drive waveform of a scan electrode voltage reaches at the end after continuously varying in the negative direction, is changed in accordance with the determined environment temperature in such a manner that if the environment temperature becomes lower, the ultimate voltage is directed in the positive direction. | 03-26-2009 |

20090231309 | Plasma Display Panel and Plasma Display Device - In a long-gap discharge using a trigger discharge in a display cell of a PDP having three electrodes (X, Y, A), a technology capable of stably generating the trigger discharge with low power consumption by using a float electrode is provided. In a dielectric layer of the PDP, a long gap is formed between first and second display electrodes, first and second float electrodes which are capacitive-coupled to the first and second display electrodes are formed, and a short gap is formed between the first and second float electrodes. A sustain pulse is applied to the first and second display electrodes, thereby generating a small trigger discharge in the short gap. Subsequently to this discharge, a main discharge at the long gap is generated. Electrodes and capacitances are structured so that the main discharge has an intensity equal to or smaller than one-fifth of an intensity of the trigger discharge. | 09-17-2009 |
