DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a plasma display panel, a method of manufacturing the same, and a display device using the same.

[0002]

2. Description of the Related Art Plasma display panels (PDPs)
The technology of flat panel display technology is higher than that of liquid crystal panels because of its higher display speed, wider viewing angle, easier size, and higher display quality due to its self-luminous type. In recent years.
Generally, in PDP, ultraviolet rays are generated by gas discharge,
The phosphor is excited by the ultraviolet light to emit light, thereby performing color display. Then, a display cell partitioned by a partition is provided on the substrate, and a phosphor layer is formed on the display cell. In particular, the current mainstream of PDPs is a surface discharge type PDP having a three-electrode structure, which has a pair of display electrodes adjacent in parallel on one substrate and a direction intersecting the display electrodes on the other substrate. It has an address electrode, a partition wall, and a phosphor layer, which can be comparatively thick, and it can be said that the phosphor layer is suitable for color display by the phosphor. FIG. 12 shows a typical surface discharge type PDP having a three-electrode structure.
FIG. The display electrode pair is a pair of a scan electrode (scan electrode) and a sustain electrode (sustain electrode). The advantages of this structure are that it has a very simple structure and is relatively easy to manufacture, the phosphor layer can be thickened and the brightness can be increased because the phosphor screen can be viewed directly, and the phosphor layer is separated from the scan electrode. Thus, the deterioration of the phosphor due to the sustain discharge can be reduced.

However, there is still a problem that the luminous efficiency is low and the luminance is low. Further, since the phosphor layer exists in the address discharge path and in the vicinity thereof, deterioration of the phosphor due to the address discharge also becomes a problem. Further, when the distance between the address electrode and the scan electrode becomes longer, the voltage at the time of address discharge rises and a discharge delay occurs, so that high-speed address driving becomes difficult. In addition, problems such as erroneous discharge between adjacent cells are likely to occur. Conversely, when the distance between the address electrode and the scan electrode is reduced, the deterioration of the phosphor due to the sustain discharge becomes serious. Further, when the phosphor layer is thickened, the discharge space becomes smaller, so that the amount of the phosphor must be necessarily reduced. Further, there is a problem of white balance.
Generally, white color having a high color temperature (10000 to 9000K) is preferred in the market.

However, in order to produce a white color having this color temperature, it is necessary to relatively increase the intensity of blue among the three colors (red, green, and blue). On the other hand, blue has a small number of types of phosphors and does not achieve sufficient strength. Therefore, since the intensity of blue with low visibility is increased by suppressing the green with high visibility by the number of pulses, maintaining the white balance further reduces the luminance.

[0005] Among the above-mentioned problems, it has been found that Japanese Patent Application No. 10-206005 can greatly improve compatibility between high luminous efficiency and high luminance and reduction in writing voltage, high speed and reliability. However, at present, the invention for improving the white balance without lowering the luminance has not been sufficiently achieved.

[0006]

As described above, the conventional PDP has low brightness and low luminous efficiency, and has problems such as deterioration of a phosphor due to an address or sustain discharge and a discharge delay at the time of an address discharge. Further, there is a problem that the brightness must be kept low to use due to the problem of white balance.

The present invention solves the above-mentioned problems, that is, it has high luminance, high luminous efficiency, high-speed and stable writing characteristics without deteriorating the phosphor, and has a high color temperature. It is an object of the present invention to provide a plasma display panel capable of expressing the above, a manufacturing method thereof, and a display device using the same.

[0008]

According to the present invention, as one means for achieving high luminance and high luminous efficiency, the present invention is limited by providing, directly or indirectly, a projection having a height lower than that of a partition on the inner surface of a substrate. In this method, the effective surface area of the phosphor in the display cell is increased, and in particular, the white balance is controlled by controlling the position of the phosphor layer by controlling the shape of the projections for each color. As a result, it is possible to suppress the deterioration of the phosphor and the defective address without largely changing the conventional method, and to greatly improve the luminance without lowering the white color temperature.

Incidentally, the term "projection" in the present invention means a "partially protruding portion", and its shape, position and number are not specified. The same applies to the material.
Further, “controlled by the shape of the projection” according to the present invention means that the projection is controlled by a shape including the number (including 0), position, height, etc. of the projection.

In the address period, a write pulse Pw is applied to the scan electrode. A write pulse Pwa is applied to the address electrode in synchronization with the write pulse.
ON / OFF of the writing pulse Pwa applied to the address electrode is controlled according to each pixel of the image to be displayed. When the write pulse Pw and the write pulse Pwa are applied at the same time, an address discharge is generated in the discharge cell at the intersection of the scan electrode and the address electrode, and the discharge cell is turned on.

In the sustain period after the address period, a sustain pulse Psc is applied to the scan electrode at a constant cycle. The phase of the sustain pulse Psc applied to the scan electrode is shifted by 180 degrees from the phase of the sustain pulse Psc applied to the sustain electrode. In this case, the sustain discharge occurs only in the discharge cells lit by the address discharge. At the end of each subfield, an erase pulse Pe is applied to the scan electrode. Thereby, the wall charge of each discharge cell is reduced to such an extent that disappearance or sustain discharge does not occur, and the sustain discharge ends.
