Problems solved by technology

However, whether reset discharge can be performed in a cell adjacent to a lit cell depends on the pulse width and voltage, and therefore, it is often very difficult to cause discharge to occur stably in all cells having characteristic variations such as discharge start voltage
[0020] As explained above, the problem is that sufficient contrast cannot be achieved under the conditions in which stable operation is guaranteed in the PDP of the ALIS type

Embodiment Construction

[0049] Before describing the embodiments of the present invention, refer to Figures 14A to 14D Describe the basic principles of operation.

[0050] FIG. 14 shows the discharge action when the driving method of the present invention is performed, in which the adjacent cell write cycle is performed before the write cycle, and after the write cycle before the erase cycle is performed.

[0051] Such as Figure 14AAs shown in , when the sustain discharge is repeated in the cell between X2 and Y2 in the sustain discharge period of the previous subfield, electrons fly to the Y1 and X3 electrodes, and accumulate. In the early stage of the reset period, the wall charges between X2 and Y2 are reduced by the erase discharge.

[0052] Secondly, if Figure 14B As shown in , when a voltage of 170V is applied to the X electrode and a negative 50V voltage is applied to the Y electrode, the negative charge on Y1 is superimposed on the applied voltage and exceeds the discharge start voltage...

Abstract

In a plasma display panel with stable performance and high contrast, even when a voltage that changes gradually as time goes by is applied between the first and the second electrodes so that a discharge is caused to occur only in a cell that was lit in the preceding subfield, the neighboring cell write, in which the wall charges that remain on one side of the different display lines contiguous to the cell that was lit in the preceding cell are eliminated, is provided before or after the write period.

Description

technical field [0001] The present invention relates to a plasma display panel and a method of driving it. More specifically, the present invention relates to a technique for improving display contrast while maintaining performance stability in a plasma display panel of the ALIS (Alternate Surface Illumination) method in which between adjacent sustain electrodes Each space of is used as a display line. Background technique [0002] A plasma display panel is a device in which a space of about 100 microns in width between two glass substrates on which electrodes are formed is filled with a mixed gas for discharge, including gases such as Ne and Xe, applied A voltage greater than the discharge initiation voltage causes discharge to occur, and the fluorescent material formed on the substrate is activated by ultraviolet rays generated by the discharge to emit light. [0003] figure 1 Shows the structure of a display device using a plasma display panel. In the display panel 10...
