| 20090040146 | PLASMA DISPLAY APPARATUS AND PLASMA DISPLAY PANEL DRIVING METHOD - A disclosed plasma display apparatus and a plasma display panel driving method provide improved luminance while preventing decrease in resolution. In the plasma display apparatus, which is adapted to the display of an interlace signal, the maximum number of sustain pulses associated with the emission of light that can be made in one field is calculated, based on the vertical synchronization signal frequency of the input signal. A display load factor of the input signal in the one field is calculated and, based on the calculated display load factor, a target number of sustain pulses in the one field is determined. Based on a relationship between the target number of sustain pulses and the maximum number of sustain pulses, an emission luminance ratio of a sub-display line to a main-display line in the one field is determined. | 02-12-2009 |

| 20090058765 | Plasma Display Device - Between a sustain circuit outputting a sustain pulse and a scan circuit (even) driving a Y electrode of an even display line, there is provided a first switch capable of making the Y electrode of the even display line be in a high impedance state, and between the sustain circuit and a scan circuit (odd) driving a Y electrode of an odd display line, there is provided a second switch capable of making the Y electrode of the odd display line be in the high impedance state. By first and second switches, the Y electrode of the even display line and the Y electrode of the odd display line can be independently controlled to be in the high impedance states, whereby discharge of the even display line can be restrained in a sustain period of an odd frame, while a discharge of the odd display line can be restrained in a sustain period of an even frame, thereby realizing an interlace drive without complicating a circuit configuration. | 03-05-2009 |
| 20090153442 | Plasma Display Apparatus - According to the invention, by forming at least every two frames having video contents corresponding to each frame of a video signal, for example, a frame rate of movie contents whose frame rate is equal to 24 Hz is converted into 48 Hz. A plurality of subfields (SFs) corresponding to each frame of the conversion signal are divided into first and second division SF groups. Each division SF group is further classified into an upper SF group on the large weight side and a lower SF group on the small weight side. The weights of the upper SF groups are made symmetrical between the first and second division SF groups. The weight of each SF belonging to the lower SF group in the first division SF is set to be larger than that in the second division SF. | 06-18-2009 |
