DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to color plasma display.
BACKGROUND ART
Since plasma display panels (PDP's), which are a typical one of discharge type display devices, have several superior characteristics as a flat plate type display device, their application has become more wide. Recently, development of color PDP's for wall tapestry televisions or portable terminals has become more active. For the sequential scanning system, such color PDP's take a short selecting enable time as compared to monochrome PDP's. The selecting enable time in color PDP's corresponds to about 1/3 that of monochrome PDP's. For this reason, research on color PDP's is being primarily concentrated on an improvement in luminance.
FIG. 1 illustrates a conventional color PDP having a quadrant-cell matrix structure.
In this PDP structure, four discharge cells R, B, B and G are grouped into a pixel by partitions V. The PDP includes one assistant electrode C per two anodes A. The assistant electrode C serves to supply priming charge to discharge cells R, G and B arranged on both sides thereof, thereby enabling a rapid primary discharge. Accordingly, it is possible to decrease the drive voltage and to extend the continued discharge time, thereby achieving an improvement in luminance.
Generally, each pixel includes two blue discharge cells B because blue fluorescent material exhibits a lower luminance than red or green fluorescent material. For this reason, it is very difficult to satisfy the white balance on the entire screen. Furthermore, the provision of the assistant electrode C results in an increase in electrode density on the substrate. As a result, it is difficult to provide a high definition display device.
DISCLOSURE OF INVENTION
Therefore, an object of the invention is to solve the above-mentioned problems encountered in the prior art and to provide a color PDP capable of easily satisfying the white balance and yet having a simple structure.
In accordance with the present invention, this object is accomplished by providing a color plasma display panel including a pixel matrix array in which discharge cells of three colors, namely, red, green and blue, are grouped to constitute a pixel, wherein the pixel comprises: a first discharge cell adapted to emit light with one of the three colors, the first discharge cell having a height smaller than the entire height of the pixel and a width equal to the entire width of the pixel; and a pair of laterally arranged second discharge cells respectively adapted to emit light with the remaining two of the three colors, each of the second discharge cells having a height corresponding to a difference between the entire height of the pixel and the height of the first discharge cell and a width less than the entire width of the pixel.
BRIEF DESCRIPTION OF THE DRAWINGS
Other objects and aspects of the invention will become apparent from the following description of embodiments with reference to the accompanying drawings in which:
FIG. 1 is a plan view illustrating a conventional color PDP;
FIG. 2 is a schematic view illustrating one pixel of a color PDP in accordance with the present invention;
FIG. 3 is a plan view illustrating one pixel of the color PDP in accordance with the present invention;
FIG. 4 is a perspective view illustrating one pixel of the color PDP in accordance with the present invention; and
FIG. 5 is a schematic view illustrating a pixel matrix array of the color PDP in accordance with the present invention.
BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 2 illustrates one pixel of a color PDP in accordance with the present invention. As shown in FIG. 2, the pixel is constituted by three discharge cells R, G and B. The blue cell B exhibiting a low luminance has a width W.sub.2 corresponding to the entire width W of the pixel X and a height H.sub.2 smaller than the entire height H of the pixel X. On the other hand, red and green discharge cells R and G have a height H.sub.1 corresponding to a length obtained after deducting the height H.sub.2 of the blue
