Problems solved by technology

However, the driving sequence for addressing to set the initial display content is complicated. In addition, since there is no reverse gap and the display electrodes involve two adjacent rows in the vertical direction, discharge interference between adjacent display cells is likely to occur.

Embodiment approach 1

[0049] figure 1 It is a partially exploded perspective view showing the structure of the PDP according to Embodiment 1 of the present invention. This PDP is an AC-driven three-electrode surface discharge type PDP for color display.

[0050] On the substrate 1 on the front side, the display electrode X and the display electrode Y are provided substantially parallel to each other. The display electrodes X and Y are respectively composed of a transparent electrode 9 made of ITO for generating surface discharge and a metal bus electrode 10 of a three-layer structure of Cr / Cu / Cr constituting a power supply line. The display electrodes Y serve as scan electrodes. Furthermore, a dielectric layer 11 is formed to cover these display electrodes X and Y, and a protective film 12 is formed on the surface thereof. Only one set of display electrodes X and Y is shown in the figure, but actually there are multiple sets according to the number of cells in the column direction.

Embodiment approach 2

[0094] Figure 6 It is a schematic diagram of the structure of Embodiment 2 of this invention.

[0095] Several embodiments can be given by changing the magnitude relationship of m, n, and o. Figure 6 , the following relationship holds.

[0096] m=o

[0097] According to the relationship of the above-mentioned formula 10, even if the area of ​​the discharge electrode in the cell opening portion not intersecting the first partition wall is fixed for each color, it is also possible to have a structure in which only the surface discharge gap of the R cell is short in the row direction. , and can narrow the voltage difference between the R unit and the G unit and the R unit and the B unit.

Embodiment approach 3

[0099] Figure 7 It is a schematic diagram of the structure of Embodiment 3 of this invention.

[0100] In the present embodiment, the following relationships are established.

[0101] n>m>o (Formula 11)

[0102] As described above, m is the distance between the R unit and the G unit, n is the distance between the G unit and the B unit, and o is the distance between the B unit and the R unit.

[0103] In this electrode structure, if the dimensions of m, n, and o and the distance between the electrode edge and the first partition wall are as follows, the length in the row direction of the surface discharge gap in the R cell, G cell, and B cell becomes Completely different constructs:

Abstract

A plasma display panel includes a pair of substrates (1, 2) pairs of discharge electrodes (9), row electrodes (10), column electrodes (13), and barrier ribs (15). The pair of substrates have R cells, G cells and B cells which respectively generate three primary colours of red, green and blue in the discharge space to form each of pixels. The pairs of discharge electrodes (9) are placed on one of the substrates for each of the R cell, G cell and B cell. The row electrodes (10), which are placed on each row of the matrix, are to supply power to each of the discharge electrodes. The column electrodes are placed on each column of the matrix on the other substrate. The barrier ribs (15) are placed between the column electrodes (13) in the column direction. The length in the row direction of the discharge electrodes is adjusted in accordance with the discharge timing of each cell for each of R cells, G cells and B cells.

Description

technical field [0001] The present invention relates to a plasma display panel (hereinafter referred to as PDP) such as a display device such as a personal computer or a workstation, a flat-screen TV, a display device for displaying advertisements or information, etc., and more particularly relates to an electrode structure of an AC surface discharge type PDP. Background technique [0002] As a conventional PDP, an AC-driven three-electrode surface discharge PDP is known. This kind of PDP arranges a large number of display electrodes capable of surface discharge along the horizontal direction on the inner surface of the substrate on one side (for example, the substrate on the front side or the display side, called the front substrate), and on the other side of the substrate (for example, the back side). On the inner surface of the substrate (referred to as the back substrate), a large number of address electrodes for selecting the light-emitting unit are arranged along the d...
