Description

  The present invention relates to a panel structure of a surface discharge type AC type plasma display panel.

  FIG. 1 is a front view schematically showing a cell structure of a conventional surface discharge AC plasma display panel (hereinafter referred to as PDP).

  The conventional PDP of FIG. 1 has a plurality of row electrode pairs (X, Y) that extend in the row direction and are juxtaposed in the column direction on the back side of a front glass substrate (not shown) to form display lines L, respectively. Is formed and covered by a dielectric layer (not shown).

  The row electrodes X and Y constituting the row electrode pair (X, Y) are respectively arranged at equal intervals along the bus electrodes Xa and Ya made of a metal film extending in a strip shape in the row direction and the bus electrodes Xa and Ya. Are formed of transparent electrodes Xb and Yb that protrude in the column direction in the direction of the paired counterpart row electrode and are opposed to each other via the discharge gap g.

  Column electrodes D extending in the column direction are arranged in parallel in the row direction on the side of the rear glass substrate (not shown) facing the front glass substrate with the discharge space interposed therebetween, and transparent electrodes Xb, It faces Yb.

  A partition wall W formed in a substantially lattice shape by a vertical wall Wa extending in the column direction and a horizontal wall Wb extending in the row direction is formed between the front glass substrate and the rear glass substrate. For each discharge cell CR, CG, CB formed in a portion of the row electrode pair (X, Y) facing the transparent electrodes Xb and Yb, the discharge space between the substrate and the rear glass substrate is It is partitioned in a matrix in the row direction and the column direction.

  A red phosphor layer (not shown) is formed on the rear glass substrate in the discharge cell CR partitioned by the barrier ribs W, and a green phosphor layer (see FIG. 5) is formed on the rear glass substrate in the discharge cell CG. A blue phosphor layer (not shown) is formed on the rear glass substrate in the discharge cell CB.

The discharge cells CR, CB, and CG are arranged in order in the row direction, and one pixel P is constituted by three discharge cells CR, CB, and CG adjacent to each other in the row direction. Yes.
The discharge space between the front glass substrate and the back glass substrate is filled with a discharge gas containing xenon gas.

Image formation in the above PDP is performed as follows.
That is, in the address period after the reset period, address discharge is selectively performed between the row electrode Y and the column electrode D of the row electrode pair (X, Y) in each discharge cell C, and the light emitting cell (dielectric material) Discharge cells in which wall charges are formed in the layer) and non-light emitting cells (discharge cells in which wall charges are not formed in the dielectric layer) are distributed on the panel surface corresponding to the image data of the video signal.

  In the next sustain discharge period, a sustain pulse is alternately applied to the row electrodes X and Y of the row electrode pair (X, Y) in all the display lines L, and each time this sustain pulse is applied, each sustain pulse is applied. A sustain discharge is generated between the row electrodes X and Y in the light emitting cell.

  The sustain discharge generates vacuum ultraviolet rays from the discharge gas in the discharge space, and the phosphor layers colored in red, green, and blue in each discharge cell C are excited by the vacuum ultraviolet rays generated from the discharge gas, respectively. By emitting visible light, an image by matrix display is formed on the panel surface.

  In recent years, there has been an increasing demand for high-definition screens for PDPs having such a configuration. For example, for a conventional 50-inch class PDP, the HD display definition of 1280 × 768 has been sufficient. However, full HD display of 1980 × 1080 and higher definition are required.

  In addition, the PDP has been closed up as a large display panel until now, but in the future, there is an increasing demand to use it as a medium-sized monitor display of, for example, a 25-inch class.

  The PDP has been originally developed for a large display. In a large display panel having a screen of 40 inches or more, it is easy to form a pixel P having a necessary size.

  However, in order to realize a high-definition screen of full HD display, for example, in a 25-inch class PDP, it is necessary to greatly reduce the size of each pixel, resulting in a significant reduction in luminous efficiency. A problem occurs.

  For example, in order to realize a high definition screen of full HD (1980 × 1080) display in a 25 inch class PDP, about 800 (μm) × 800 (μm) used in the current 50 inch size PDP. The area of the pixel P needs to be set to an area of about 300 (μm) × 300 (μm), which is one-seventh of the area.

  In order to perform stable plasma discharge while maintaining high luminous efficiency in the PDP, it is necessary to secure the plasma discharge region by setting the area of the pixel P to be larger than a required dimension. There is a limit to reducing the size.

  FIG. 2 shows the configuration of one pixel of a conventional PDP, and the discharge cells CR, CB, and CG constituting the pixel P have the same area.

  In FIG. 2, A represents the length of one side of the pixel P in the row direction, a represents the width of each discharge cell CR, CB, CG in the row direction, and b represents the discharge cell CR, CB, CG. The width in the column direction, and t, the width in the row direction of the vertical wall Wa of the partition wall W that partitions between the discharge cells CR, CB, and CG adjacent in the row direction.

  As shown in FIG. 2, the pixel P constituted by the substantially rectangular discharge cells CR, CB, CG having a short row direction and a long column direction has a high light emission efficiency in each of the discharge cells CR, CB, CG. In order to be secured, the length a in the row direction must be at least 100 μm, the length b in the column direction must be 150 μm or more, and if the length a is smaller than 100 μm, the light emission efficiency Has been found to be extremely worse.

  Furthermore, the width t of the vertical wall Wa that partitions the discharge cells CR, CB, and CG is also required to be at least 40 μm in order to reliably partition the discharge cells CR, CB, and CG adjacent to each other.

Therefore, when trying to ensure high luminous efficiency in the pixel P of FIG. 2, the required width A in the row direction is
A = 3a + 2t
From the above formula, it becomes 380 μm or more.

  That is, with the pixel structure of the conventional PDP, for example, a pixel size of 300 μm × 300 μm necessary for realizing a full HD (1980 × 1080) display screen on a 25-inch class display panel cannot be secured.

  FIG. 4 shows the configuration of one pixel in the PDP.

  In FIG. 4, one pixel P1 of the PDP includes one first discharge cell C1R, and second discharge cells C1G and third discharge cells that are positioned on the left side of the first discharge cells C1R and arranged in the column direction. It is composed of three C1B discharge cells.

  In the first discharge cell C1R, the width a1 in the row direction is set to a required size as described later, and the width b1 in the column direction is substantially equal to the interval between the bus electrodes X1a and Y1a in the row electrode pair (X1, Y1). It has a substantially rectangular shape that is long in the column direction and is set to an equal size.

  Each of the second discharge cell C1G and the third discharge cell C1B is set to a required size in which the width a2 in the row direction is larger than the width a1 in the row direction of the first discharge cell C1R as will be described later. The width b2 has a substantially rectangular shape that is long in the row direction and is set to a size that is half or less of the width b1 in the column direction of the first discharge cell C1R.

  The width t1 of the first vertical wall W1a, the second vertical wall W1b, and the second horizontal wall W1d of the partition wall W1 that partitions the first discharge cell C1R, the second discharge cell C1G, and the third discharge cell C1B will be described later. The required size is set.

  That is, the first discharge cell C1R has a row-direction width a1 of 100 μm, the second discharge cell C1G and the third discharge cell C1B have a row-direction width a2 of 150 μm, and a column-direction width b2 Is set to 100 μm.

  As described in the description of FIG. 2, in order to maintain the light emission efficiency necessary for image formation by one discharge cell, the width in the short direction of the discharge cell is 100 μm or more, When the width is required to be 150 μm or more and the discharge cell is smaller than these dimensions, the luminous efficiency is extremely deteriorated. Therefore, the first discharge cell C1R, the second discharge cell C1G, and the third discharge cell C1B are This is because each has a minimum necessary width in the column direction.

  The width t1 of the first vertical wall W1a, the second vertical wall W1b, and the second horizontal wall W1d of the partition wall W1 is set to 40 μm.

  This is because, as described in the description of FIG. 2, at least 40 μm is necessary in order to reliably separate adjacent discharge cells.

Therefore, the width b1 of the first discharge cell C1R in the column direction is approximately
b1 = b2 × 2 + t1
= 240 μm
It becomes.

By setting the width in the row direction and the column direction of the first discharge cell C1R, the second discharge cell C1G, and the third discharge cell C1B as described above, the width A1 in the row direction of the pixel P1 is approximately
A1 = a1 + a2 + t1
= 290μm
It becomes.

  Further, the width B1 in the column direction is approximately 240 μm, which is the same as the width b1 in the column direction of the first discharge cells C1R.

  As described above, according to the configuration of the PDP according to the above-described embodiment, each pixel necessary for realizing a high-definition screen for full HD display in the 25-inch class PDP as described in the background section above. The area (about 300 (μm) × 300 (μm)) can be satisfied.

  The first discharge cell C1R and the first discharge cell C1R are formed in the first discharge cell C1R having the largest area by forming a red phosphor layer having a relatively low luminance compared to the green and blue phosphor layers. The brightness balance between the two discharge cells C1G and the third discharge cells C1B can be maintained.

  Accordingly, it is possible to reduce the area of one pixel that could not be realized with the conventional PDP while maintaining high light emission efficiency, so that the screen of the PDP can be made high definition and, for example, a medium-sized PDP of 25 inch class In this case, it becomes possible to realize high definition of the screen.

  FIG. 5 is a front view schematically showing a configuration of one display line of the PDP of the second example according to the embodiment of the present invention.

  In FIG. 5, the PDP of the second embodiment extends in the row direction (left and right direction in FIG. 5) on the back side of the front glass substrate (not shown), and is arranged in parallel in the column direction (up and down direction in FIG. 5). Thus, a plurality of row electrode pairs (X2, Y2) each forming the display line L2 are formed and covered with a dielectric layer (not shown).

In addition, the substantial plasma discharge region becomes longer than in the case of the first embodiment, thereby improving the light emission efficiency, and accordingly, in the row direction of the second discharge cell C3G and the third discharge cell C3B.

Accordingly, the luminance balance between the first discharge cell C3R, the second discharge cell C3G, and the third discharge cell C3B is maintained.

  As described above, according to the PDP of the above embodiment, as with the PDP of the first embodiment, it is possible to reduce the area of one pixel that could not be realized with the conventional PDP while maintaining high light emission efficiency. The PDP screen can be made high-definition and, for example, in a medium-size PDP of a 25-inch class, the screen can be made high-definition and the size of the pixel P3 is set to the first size. Since it can be made even smaller than in the case of the PDP in the example, it is possible to realize further high definition of the screen.

Therefore, the black luminance contrast of the formed image can be improved, and the black when the discharge cell is not lit can be enhanced.
