The present invention relates to a plasma display panel (PDP).

When the potential difference between two spaced points increases, discharge occurs. In particular, a so-called gas discharge phenomenon, in which a large discharge occurs when gas is present in the space, is applied to a PDP and used for image display.

The simplest configuration of such a PDP is a direct current (DC) type PDP as shown in FIG. 1, which is arranged on two substrates P1 and P2 so as to face electrodes X and Y that cross each other. It divides into and discharges by selection of the two electrodes X and Y, and displays an image.

However, in the DC PDP, discharge is maintained only when the electrodes X and Y are selected, and a delay occurs even at the start of discharge, which is not suitable for high resolution moving picture display.

In contrast, an AC-type PDP shown in FIG. 2 forms a wall charge W by embedding either electrode Y or X in the dielectric layer I, and is quickly It is causing a strong discharge.

However, since DC PDP uses a single polarity power supply, it is much easier to drive than AC PDP. As a result, various hybrid PDPs, which improve DC PDPs or combine the advantages of both, have appeared. FIG. 3 shows a multi-electrode type PDP, one or two parallel to any one electrode (Y). By arranging the auxiliary electrodes S1 and S2, an auxiliary discharge or sustain discharge is caused between the electrode Y and the auxiliary electrodes S1 and S2 to trigger or maintain a main discharge between the two electrodes X and Y. have.

On the other hand, it is shown in Figure 4 is a trigger type PDP, which is embedded in the trigger electrode (T) by embedding the trigger electrode (T) through the dielectric layer (I) below any one electrode (X or Y). The trigger discharge is caused between the electrodes X to trigger the discharging between the two electrodes X and Y.

By the way, the multi-electrode PDP is effective in maintaining the discharge, and the trigger type PDP is effective in the rapid onset of discharge, that is, the trigger.

Accordingly, an object of the present invention is to provide a PDP capable of simultaneously achieving the discharge sustaining characteristics of a multi-electrode PDP and the triggering characteristics of a triggered PDP.

PDP according to the present invention for achieving the above object is

A first auxiliary electrode arranged with a dielectric layer interposed below the one electrode;

And a second auxiliary electrode arranged to be spaced apart from the first auxiliary electrode by a predetermined interval in the lateral direction.

In this configuration, rapid discharge is started between the two electrodes by trigger discharge between the electrodes stacked up and down with the dielectric layer interposed therebetween, and auxiliary or sustain discharge is applied between the first and second auxiliary electrodes arranged in the horizontal direction. It will maintain the electrical discharge between the two electrodes.

Such features of the present invention will become more apparent from the following description of the preferred embodiments with reference to the attached drawings.

In FIG. 5, the PDP of the present invention basically includes two electrodes (X, Y), which are arranged to face each other on a matrix on two substrates (P1, P2), as main electrodes, and on the partition wall (B). It is divided by to form a plurality of pixels.

A dielectric layer I is interposed between a lower portion of one of the electrodes X and Y of the substrates P1 and P2 (for example, Y) (the upper portion in the drawing but in the stacking order with respect to the substrate P1). The second auxiliary electrode S2 is spaced apart from the first auxiliary electrode S1 laterally by a predetermined interval so that the electrode Y and the two auxiliary electrodes S1 and S2 form an electrode group in one direction. have.

Here, since the electrode (Y) and the first auxiliary electrode (S1) are stacked closely up and down, even if a low potential power is applied to the first auxiliary electrode (S1), triggering a discharging between the two electrodes (X, Y). In this case, the first auxiliary electrode S1 may be used as a trigger electrode to quickly start discharging.

On the other hand, between two auxiliary electrodes (S1, S2) arranged in the horizontal direction, the power supply generates an AC discharge by alternating supply, thereby maintaining the discharge between the two electrodes (X, Y).

In the PDP of the present invention, the second auxiliary electrode S2 supplies priming particles in the discharge space by forming wall charges, and the first auxiliary electrode S1 discharges electricity between the two electrodes X and Y. The two auxiliary electrodes S1 and S2 may be configured to be independent of each other to trigger the signal.

Specific driving schemes and operating conditions of the PDP of the present invention will be further embodied in subsequent practical experiments and will be supplemented by a separate application.

As described above, the PDP of the present invention can simultaneously exhibit the rapid discharge start of the trigger type PDP and the stable discharge holding characteristic of the multi-electrode type PDP, thereby displaying a high resolution moving image with excellent image quality.
