Problems solved by technology

This will cause at least two problems: First, since the time available for displaying actions in each frame is fixed, lengthening the time for scanning actions is equivalent to shortening the time for maintaining actions
However, the length of time to maintain the action directly determines whether the brightness of the plasma display is sufficient, so the brightness of the plasma display using this method will be insufficient.
In addition, since the time of the scanning action is limited by the time available for the entire frame display action, this method cannot be applied to high-definition plasma displays.

Embodiment Construction

[0022] To achieve the above and other objectives, the present invention divides the plasma display into several (eg: 2) regions, and repeats the scanning and sustaining operations of these regions, so as to increase the duration of the sustaining operation, thereby increasing the brightness of the plasma display.

[0023] In such a driving method of a plasma display, the plasma display is first divided into two or more regions. Then, these regions are reset and scanned in sequence, and after the scanning operation of any region is completed, the maintenance operation of any region is performed simultaneously with the scanning operation of the next region. In addition, the resetting operation in any area cannot be repeated with the scanning and maintaining operations in other areas, so as to avoid signal interference between different areas.

[0024] refer to Figure 5 , which is a schematic diagram of the driving method of the plasma display of the present invention. In this...

Abstract

The display of subfield includes resetting, scanning and maintaining discharge of a plasma display, and generally, the display of one frame consists of the display of several subfields. The drive of the present invention includes: dividing a plasma display into several, say two, areas and then resetting and scanning the areas successively. The maintaining discharge of any area is completed while the scanning of the next area is completed, and this can increase maintaining period. In addition, any area is reset only when the other areas do not in their scanning and maintaining period, or else the signal in different area produces mutual interference.

Description

technical field [0001] The present invention relates to a driving method, in particular to a driving method of a plasma display, which mainly divides the plasma display into two areas, and repeats the scanning action and the sustaining action of these two areas, so as to increase the time of the sustaining action Ratio, thereby increasing the brightness of the plasma display. Background technique [0002] In the existing plasma display driving methods, the plasma display is considered as a whole, and its basic driving principle is to divide a subfield display action (Subfield) into: reset action (Reset), scan action (Scan), Sustain action (Sustain). For the eight sub-field display operations (take the 256-color grayscale plasma display as an example), these three operations are repeated in sequence to complete a frame display operation (Frame). [0003] In this method, the scanning action occupies most of the time of the whole frame display action, but contributes the leas...
