Abstract: A driving apparatus for driving a plasma display panel and a method of driving the same are disclosed. The plasma display panel includes multiple display cells, with each of the display cells comprising a sustain electrode, a scan electrode, and a data electrode. Every set of the electrodes has a corresponding driving circuit to provide a required driving waveform for driving the display cell to luminesce. The driving method includes the following steps: first, a first erase pulse, a priming pulse, and a second erase pulse are applied in sequence during a reset period. Then, data pulses corresponding to the display cells are applied during an address period. Lastly, multiple sustain pulses and multiple high frequency driving pulses are applied simultaneously during a sustain period.

Abstract: A plasma display panel (PDP) having a priming electrode is disclosed. The PDP has a first substrate and a second substrate, wherein the second substrate is opposite to the first substrate. The space between the first substrate and the second substrate is defined as a discharge space and is filled with a discharge gas. A sustaining electrode, a scanning electrode and a priming electrode are all positioned on the first substrate along a first direction. An address electrode is positioned on the second substrate perpendicularly with the first direction. The priming electrode outputs a first priming pulse so as to excite the discharge gas and to produce a plurality of discharge ions.

Abstract: A method for compensating luminance, suitable for use in a plasma display panel. The method includes the following steps. First, the luminance value of each pixel signal is read out. Then, the load of the pixel signal row is computed. The load is the number of pixel signal in the pixel signal row that the luminance value of the pixel signal is larger than a predetermined threshold luminance value. Then, a primary luminance compensation value is decided according to the load of the pixel signal row. A number of secondary luminance compensation values are decided according to the primary luminance compensation value. Afterwards, each pixel signal in the pixel signal row is performed luminance compensation sequentially. If the luminance value is larger than or equal to a low threshold luminance value, the luminance value is subtracted by the primary luminance compensation value. If the luminance value is less than the low threshold luminance value, the luminance value is subtracted by the corresponding secondary luminance compensation value. Finally, the compensated pixel signal row is outputted.

Abstract: A PDP driving method, at the first timing point of a reset period, a global voltage difference is applied between the sustaining electrodes and the scanning electrodes, wherein the gaseous discharge occurs only in the non-display areas, called the dark areas. Because the discharge during reset period does not occur in the display areas, the picture quality is assured from avoiding the emission of over-brightness in the reset period which enables the sequential gaseous discharge operations to proceed with smaller driving voltage.
