Abstract

The present invention provides a plasma display driving method. The present invention is that on the basis of the original waveforms of an X electrode maintaining pulse and a Y electrode maintaining pulse, the time difference between the X electrode maintaining pulse and the Y electrode maintaining pulse is increased; in the period of the time difference, an A electrode driving device is provided with an instantaneous pulse; the A electrode driving device is provided with a larger pulse after the maintaining period. The present invention not only can improve the luminous efficiency of a plasmadisplay, but also can solve the problem of picture retention of a palsma display.

Description

A kind of plasma display dirving method

Technical field

The present invention relates to a kind of driving method of display, particularly a kind of driving method as the big screen plasma display.

Background technology

Because plasma display (PDP) has big picture, large scale, advantage such as ultra-thin, thereby it more and more is widely used.But PDP also exists luminescence efficiency low, the defective that brightness is low.At present, many technology that address the aforementioned drawbacks and method are also arranged, for example: change erasing pulse shape, use plasma adaption brightness Enhancement Method and add the method for A electrode satellite pulse, but the raising to luminescence efficiency of these methods is not very obvious.

Summary of the invention

The objective of the invention is to overcome the shortcoming of above-mentioned prior art, proposed a kind of plasma display dirving method, have the luminescence efficiency of improving plasma display, and can improve the characteristics of the picture retention problems of plasma display.

The technical scheme that realizes plasma display dirving method of the present invention is, keep the conventional ADS driving waveform of preparatory stage and address period constant, the drive waveforms of phase is kept in modification, the method of revising is that increase X, Y electrode are kept the mistiming between the pulse, and, on the A electrode drive, increase a transient pulse in this period mistiming.

The present invention is by improving the method that X, Y electrode drive keep the phase waveform, promotes plasma display in effective discharge of the phase of keeping, thereby improves luminescence efficiency, and can improve the picture retention problems of plasma display.

Description of drawings

Fig. 1 is X, the Y of traditional driving method, the drive waveforms figure of A electrode.

Fig. 2 is the traditional phase of keeping X, Y, the oscillogram of A electrode.

Fig. 3 is the drive waveforms figure of X of the present invention, Y, A electrode.

Fig. 4 is the phase of the keeping drive waveforms figure of X of the present invention, Y, A electrode.

With reference to shown in Figure 1, what this figure illustrated is the driving of a traditional ADS type of drive Waveform. Voltage at maintenance phase A electrode is to keep high level constant, the electricity of X and Y electrode Pressure is that the square wave interval forms.

With reference to shown in Figure 2, what this figure illustrated is that a traditional ADS type of drive is being kept The drive waveforms of phase is that Fig. 1 is in the amplification of maintenance phase. Voltage at maintenance phase A electrode is Keep high level constant, the voltage of X and Y electrode is that the square wave interval forms.

With reference to shown in Figure 3, what this figure illustrated is the drive waveforms of the type of drive after improving. During showing, increase false impulse on the A electrode, improve the luminous efficiency of plasma display. Voltage at maintenance phase A, X and Y electrode all is that the square wave interval forms.

With reference to shown in Figure 4, this figure explanation be type of drive driving in maintenance phase after improving Moving waveform is that Fig. 3 is in the amplification of maintenance phase. Voltage at maintenance phase A, X and Y electrode All formed by the square wave interval.

Specific implementation method

The method that the present invention proposes has taken into full account the possibility that realizes, can just can realize through revising on the conventional ADS driving mode fully, keeps the conventional ADS driving waveform of preparatory stage and address period constant, just revises and keeps the drive waveforms of phase.

In the phase of keeping, increase X, the Y electrode is kept the mistiming between the pulse, and, on the A electrode drive, increase the one-period transient pulse in this period mistiming, the magnitude of voltage that it is characterized in that keeping the phase pulse for+150V～+ 185V, the duration is 3～5us; The magnitude of voltage of the transient pulse of the A electrode that is increased is 20～50V, and the duration is 2～3us.When the phase of keeping will finish, increase the pulse that amplitude is bigger in last of A electrode drive in cycle, promptly magnitude of voltage is 1.3～2.0 times of front A electrode voltage.
