Benefits of technology

This approach ensures reliable addressing and reduces the time necessary for addressing, preventing display defects by maintaining effective space charge for addressing discharge across all cells, thereby enhancing the overall display performance.

Problems solved by technology

For this reason, in a cell of a row that is selected at relatively late timing, there was a case where the addressing discharge cannot occur within the row selection period (scanning period for one row) defined by a scan pulse width, resulting in a display defect.
An example of the display defect is a “black noise” in which a part or a whole of the upper edge of a belt cannot be lighted, when the belt is displayed in the lower portion of the screen that is scanned vertically.
Especially, in the structure in which the discharge space is defined by a diaphragm having a stripe pattern for each column, movement of the space charge generating the priming effect can occur only in each column, resulting in a display defect.
However, in the conventional driving method, since a priming pulse for generating the priming discharge is applied to the next row to be selected at the same time as application of the scanning pulse to the selected row, it is difficult to optimize the pulse width and the peak value, so that the control becomes complicated.

Embodiment Construction

[0032]FIG. 2 is a schematic drawing of a plasma display device 100 in accordance with the present invention.

[0033]The plasma display device 100 includes an AC type plasma display panel 1 that is of a thin-type and matrix-type color display device and a driving unit 80 for selectively lighting a plurality of cells C that make up a screen ES having m columns and n rows. The plasma display device 100 is used for a wall-hung television set or a monitor of a computer set.

[0034]The plasma display panel 1 has main electrodes X, Y that makes up electrodes pairs and are arranged in parallel for generating sustaining discharge (or also called display discharge). The main electrodes X, Y and address electrodes A cross each other in each cell C so as to form the three-electrode plane discharge structure. The main electrodes X, Y extend in the row direction (the horizontal direction) of the screen ES, and the main electrode Y is used for a scanning electrode that selects cells C row by row in ad...

Abstract

When performing the line-sequential addressing for setting the state of each of the cells arranged in rows and columns that constitute a display screen, discharge is generated that has intensity in accordance with display data corresponding to each of all cells belonging to the selected row for each selection of the row. Thus, the priming effect in the following discharge is generated.
