Embodiment Construction

[0027] According to the first exemplary embodiment of the present invention, refer to Figure 4 A method for driving a plasma display panel is described, wherein A, Y, and X are used to denote address electrodes, scan electrodes, and sustain electrodes, respectively. A voltage is applied to the address electrodes, scan electrodes and sustain electrodes. When the address electrodes and the scan electrodes are denoted by Ai and Yi, respectively, corresponding voltages are applied to the address electrodes and the scan electrodes.

[0028] Such as Figure 4As shown, the waveforms according to the first exemplary embodiment of the present invention have a reset period, an address period and a sustain period. The plasma display panel and the scan / sustain driving circuit ( figure 2 20 in ) and an address driving circuit for applying a driving voltage to the address electrodes A1 to Am ( figure 2 30) in the joint. The driving circuit and the plasma display panel are joined to ...

Abstract

A method for driving a plasma display panel. In the method, a gradually rising ramp voltage is applied in the reset period, and a final voltage of a falling ramp voltage is reduced to generate discharges in discharge cells. A difference between voltages applied to an address electrode and a scan electrode in a discharge cell to be selected is established to be greater than a maximum discharge firing voltage. Positive wall charges and negative wall charges are respectively accumulated in the scan electrode and the sustain electrode by applying the falling ramp voltage while the sustain electrode is biased at a predetermined voltage before the reset period.

Description

technical field [0001] The present invention relates to a plasma display, and more particularly to a method for driving a plasma display panel (PDP). Background technique [0002] A PDP is a flat panel display that displays characters or images using plasma generated by gas discharge, and includes more than several million to tens of millions of pixels arranged in a matrix, where the number of pixels is limited according to the size of the plasma display panel . refer to figure 1 and figure 2 The structure of a conventional PDP will be described. [0003] figure 1 shows a partial perspective view of the PDP, figure 2 show figure 1 Electrode settings in the PDP. The PDP includes two glass substrates 1, 6 facing each other with a gap therebetween. Pairs of scan electrodes 4 and sustain electrodes 5 are arranged in parallel on the first glass substrate 1 , and the scan electrodes 4 and the sustain electrodes 5 are covered with a dielectric layer 2 and a protective fil...
