AI Technical Summary

Problems solved by technology

If the idle interval is enlarged, that is, if the time for supplying the sustain pulse between the current sustain period and the next sustain period is set long, the sustain drive margin is deteriorated.
For example, if the idle interval is enlarged, electron charge particles generated by the previous sustain discharge are wasted due to their re-accumulation, thereby causing an unstable sustain discharge

Embodiment Construction

[0049] Figure 5A and 5B A graph showing the frequency of the sustain pulse of the APL according to the first embodiment of the present invention.

[0050] Such as Figure 4 As shown, the APL has an inverse relationship with the number of sustain pulses. In other words, when the APL goes high, a small number of sustain pulses are applied to the panel, and when the APL goes low, a large number of sustain pulses are applied to the panel. At this time, in the first embodiment of the present invention, the period of the sustain pulse is set to increase linearly (ie, the frequency of the sustain pulse is set to decrease linearly) due to going from low APL to high APL as shown in FIG. 5 . Here, the number of actually applied sustain pulses is set in the same manner as in the prior art.

[0051] In particular, in low APL, i (eg 1024) sustain pulses are applied to the panel. In this case, the period T2 of the sustain pulse having an inverse relationship with the frequency f2 has ...

Abstract

A method and apparatus for driving a plasma display panel that is adaptive for improving a sustain driving margin. In the method and apparatus, the number of sustaining pulses is set in response to an average picture level. A period of the sustaining pulse is set in proportion to said average picture level.

Description

technical field [0001] The present invention relates to a plasma display panel, and more particularly, to a method and apparatus for driving a plasma display panel suitable for improving sustain driving margin. Background technique [0002] In general, a plasma display panel (PDP) is a display device using visible light emitted from a phosphorous material when the phosphorous material is excited by gas discharge to generate vacuum ultraviolet rays. The PDP has an advantage that it has a thinner thickness and lighter weight than existing cathode ray tubes, and can realize a high resolution and a wide area screen. The PDP includes a plurality of discharge cells arranged in a matrix, and each discharge cell constitutes a screen element or pixel of the screen. [0003] FIG. 1 is a perspective view showing a discharge cell structure of a conventional three-electrode, AC surface discharge PDP. [0004] Referring to FIG. 1 , a discharge cell of a conventional three-electrode, AC ...
