Problems solved by technology

In addition, the positioning time can be reduced by driving the plasma display panel in a dual-scanning system that divides and scans two areas, but at this time, it is necessary to drive drivers for each area, so the cost will increase.

Abstract

A plasma display device and a driving method thereof are provided to accelerate the operation speed of the plasma display device by reducing an addressing time. A plasma display device includes a plasma display panel(100), a scan driver(123), and a timing controller(121). Plural scan electrodes are formed on the plasma display panel. The scan driver drives plural scan electrodes. The timing controller adjusts the number of sub-fields according to the load amount of an image signal to be displayed on the plasma display panel. The timing controller controls the scan driver, so that a portion of the scan electrodes are scanned during an address period of at least one sub-field according to the adjusted number of sub-fields. The timing controller reduces the number of sub-fields as the load amount decreases.

Description

technical field [0001] The present invention relates to a plasma display device and its driving method. Background technique [0002] A general plasma display panel consists of an interlayer formed between the front substrate and the back substrate to form a unit cell (cell), and each cell (cell) is filled with neon (Ne), helium (He) or a combination of neon and helium. Main discharge gas such as mixed gas (Ne+He) and a small amount of inert gas containing xenon (Xe). When the high-frequency voltage causes discharge, the inert gas generates vacuum ultraviolet rays (Vacuum Ultraviolet ray), which makes the phosphors formed between the interlayers emit light and display images. Such a plasma display panel has a light and thin structure, and is attracting attention as a next-generation display device. [0003] FIG. 1 is a schematic structural diagram of a plasma display panel in the prior art. [0004] As shown in Figure 1, the plasma display panel is composed of the display...
