Embodiment Construction

[0033] Hereinafter, the plasma display device in the present invention will be described in detail with reference to preferred embodiments and accompanying drawings.

[0034] FIG. 1 is a schematic diagram of a plasma display device in the present invention.

[0035] Referring to FIG. 1 , the plasma display device in the present invention includes: a plasma display panel 100 and a driving unit 104 .

[0036] The plasma display panel 100 is combined by a front panel (not shown) and a back panel (not shown) at a certain distance, and forms a plurality of electrodes, for example, a plurality of scan electrodes (Y) and sustain electrodes (Z). Among them, the address electrodes (X) should also be formed to intersect the scan electrodes (Y) and the sustain electrodes (Z). The structure of the above-mentioned plasma display panel (100) will be described in detail in conjunction with FIG. 2 as follows.

[0037] FIG. 2 is a schematic diagram of an example of the structure of the plasm...

Abstract

Disclosed is a plasma display device, comprising a plasma display panel which forms a plurality of electrodes; at least one frame is different from the other frames in a plurality of frames, driving the driving component of the electrodes with a different number of sub-fields. The invention takes account of the average picture level, changes the number of the sub-field in the frame, and changes the average picture level, therefore depressing the generation of flicker which degrades the image quality during the driving process.

Description

1. Technical field [0001] The present invention relates to a plasma display device, and more specifically to a plasma display device that changes the number of sub-fields contained in a frame (frame) in consideration of the average picture level (Average Picture Level: APL), Among them, the plasma display device includes: a plasma display panel on which a plurality of electrodes are formed; and a drive unit that drives the electrodes of the plasma display panel. 2. Background technology [0002] A general plasma display panel consists of an interlayer formed between the front substrate and the back substrate to form a discharge cell (cell), and each discharge cell (cell) is filled with neon (Ne), helium (He), or neon and helium The main discharge gas such as mixed gas (Ne+He) and a small amount of inert gas containing xenon (Xe). The discharged cells (cells) form a plurality of pixels (Pixels) for displaying images. For example, red (Red, R), green (Green, G), and blue (Bl...
