Embodiment Construction

[0034] In the following detailed description, only one preferred embodiment of the invention has been shown and described, merely by way of illustration of the preferred mode contemplated by the inventors. As will be realized, the invention is capable of modification in various obvious respects, all without departing from the invention. Accordingly, the drawings and description are to be regarded as illustrative in nature and not restrictive.

[0035] Figure 4 A block diagram of a PDP with variable address voltages according to a first preferred embodiment of the present invention is shown.

[0036] As shown, the PDP with variable address voltages includes a plasma panel 100 , a controller 400 , a scan driver 200 , a sustain driver 300 and an address driver 500 .

[0037] The plasma panel 100 includes a plurality of address electrodes A1 to Am arranged in a row direction, and a plurality of scan electrodes Y1 to Yn and sustain electrodes X1 to Xn alternately arranged in one...

Abstract

A method for driving a plasma display panel (PDP) of different address voltages that comprises a plurality of address electrodes, scan electrodes, and sustain electrodes, a scan and a sustain electrode forming a pair and being parallel with each other and crossing an address electrode, and their crossing point forming a discharge cell, comprises steps of supplying a rising ramp signal for reset discharging and a subsequent falling ramp signal to the scan electrode, and supplying voltage signals differently established according to cell colors to the address electrode during the rising ramp period to reset the respective cells, supplying an address waveform for selecting and writing cells to be turned on and off, after the reset stage,; and supplying a sustain waveform for discharging the cell set to be turned on.

Description

technical field [0001] The invention relates to a plasma display panel (PDP) with variable address voltage and its driving method. More particularly, the present invention relates to a PDP and a driving method thereof for changing the voltage of an address electrode corresponding to red, green and blue fluorescent materials in a reset period, and for driving an AC used as a computer monitor or a television set. This voltage is controlled during PDP to reliably maintain discharge and improve contrast. Background technique [0002] PDPs that display images using plasma discharge are generally classified into DC PDPs and AC PDPs according to a discharge cell structure and a waveform of a driving voltage applied thereto. The complex structure, poor performance and short service life of DC PDP lead to the development of AC PDP. [0003] Such as figure 1 As shown, the conventional AC PDP includes a multi-layer substrate and provides a thinner, lighter an...
