Problems solved by technology

[0018] However, blindly reducing the number of reset pulses in one frame may cause misdischarge, so blindly reducing the number of reset pulses at this point will cause the problem of dependence on the panel and waveform

Embodiment Construction

[0044] refer to Figure 6 to Figure 8 , the driving method of the plasma display panel is described in the first example of the invention. Figure 6 It is an explanatory diagram of driving waveforms within one frame in the driving method of the plasma display panel of the present invention. Figure 7 yes Figure 6 Partial enlarged view of part A in middle.

[0045] Figure 8 It is a diagram of the driving method of the plasma display panel of the present invention, and reset pulses are sequentially applied within a predetermined time period.

[0046] Such as Figure 6 As shown, when afterimages occur in the first frame and the second frame consecutive to the first frame, the second frame can apply a reset pulse at least in any subfield, and has the function of adjustment. For example, if 12 previous reset pulses are applied in 12 subfields with On cell in the first frame, after-image pattern will occur when the second frame in the next frame is Off cell. Here, the second...

Abstract

The invention discloses a driving method of a plasma display panel, which uses a plurality of frames for image representation. Conditioning is performed by applying a reset pulse at least in any one of the subfields. After the reset pulse waveform applied in the reset interval is improved in the present invention, dark afterimages are significantly reduced, and the problem of image jumping is obviously improved.

Description

1. Technical field [0001] The present invention relates to the invention of eliminating the afterimage of the plasma display panel. In more detail, it is a driving method of a plasma display panel that applies an improved reset pulse waveform in a reset interval to reduce dark afterimages. 2. Background technology [0002] Generally, the partition wall formed between the front plate and the rear plate of the plasma display panel is composed of a unit, and the neon (Ne), helium (He) or the mixed gas of neon and helium (Ne+He) and the like in each unit The main discharge gas is filled with an inert mixed gas containing a small amount of xenon. When the high-frequency voltage is discharged, the inert gas emits vacuum ultraviolet rays (Vacuum Ultra Violet rays) to form phosphors between the partition walls to emit light and form an image. Lighter, thinner, more powerful, and clearer display products than this plasma display panel are on the horizon. [0003] figure 1 It is a...
