Problems solved by technology

[0015] Therefore, if the power is turned on when the wall charges are not evenly distributed, the time of the pre-test period for ensuring that the discharge cells have stable discharge characteristics will be delayed before normal driving is performed on each sub-region.
In this way, it is very difficult to drive the PDP at high speed.

Embodiment Construction

[0032] Hereinafter, preferred embodiments according to the present invention will be described in more detail with reference to the accompanying drawings.

[0033] FIG. 4 is a block diagram showing the structure of a driving device for a plasma display panel according to the present invention. As can be seen with reference to Fig. 4, for the driving device according to the plasma display panel of the present invention, it comprises the following several parts: format conversion device 410; Data conversion device 420; Storage device 430; Drive control device 440; And X electrode The driving device 450a, the Y electrode driving device 450b, and the Z electrode driving device 450c.

[0034] The format converting device 410 includes an A / D converting device and a scaler inside. Its function is to convert the analog image signal input from the outside into a digital signal. At the same time, the video signal is processed.

[0035] The function of the above-mentioned data convers...

Abstract

The invention discloses a cell plasma display panel (PDP) driving device and method. And the invention comprises the parts of: format converter for converting external input video signal into the signal suitable for the PDP to output and besides, processing the video signal; data converter for converting the processed video data into the data able to express a certain brightness; storage device for rearranging the processed data in sequence to process the processed data into the data able to be used by each subregion; and drive control device for driving any electrode driving device to generate a terminating waveform which can make wall charges in discharge cells in the PDP uniformly distributed when power supply OFF signal is inputted from the outside. When the power supply is off, it can make the wall charges in the discharge cells uniformly distributed so as to be able to assure stable picture display.

Description

technical field [0001] The invention relates to a driving device and a driving method of a plasma display panel. In particular, when the power supply of the plasma display panel is turned off during the working process, the wall charges in the discharge unit are evenly distributed, and when the plasma display panel is driven, a driving device and the plasma display panel capable of generating stable discharge drive method. Background technique [0002] Generally speaking, a plasma display panel (Plasma Display Panel: hereinafter referred to as "PDP") uses the 147nm ultraviolet rays generated by the discharge of the inert gas mixture of He+Xe or Ne+Xe to make the phosphor emit light, so as to include Images including text or graphs are displayed. [0003] This kind of PDP is not only easy to achieve ultra-thin and large-scale, but also with the further development of recent research and development technology, the picture quality of the displayed image has also been greatly...
