[0012]

The conventional AC type P
Each discharge cell in the DP 151 includes a phosphor layer 108R,
Except that the materials of 108G and 108B are different for each emission color, they are configured with the same shape and size and material. Further, in the conventional PDP 151, all the discharge cells are driven by the same predetermined voltage in the address period and the like. Therefore, the conventional PDP 151 has the following problems.

Problem: An erroneous address discharge (address erroneous discharge) depending on each emission color is likely to occur in the address period.

The minimum potential difference Vc between the electrodes Am and Yn required to generate an address discharge between the address electrode Am and the scan electrode Yn during the address period is determined by the material characteristics of the phosphor layers 108R, 108G and 108B. Is different for each emission color, that is, for each scanning line or display line Ln. Here, the voltage Vc in the discharge cell or the scanning line for each of the red (R), blue (B), and green (G) emission colors is referred to as voltage (value) Vcr, Vcb,
Assuming that Vcg, for example, there is an order of Vcr <Vcb <Vcg (1). In the following description, the “voltage (value) Vc” will be referred to as the voltage (value) Vcr, Vcb, Vc.
Also treated as a generic term for g.

The above-described influence of the order of the voltages Vcr, Vcb, and Vcg on the PDP 151 is apparent when, for example, an address discharge is generated in all the discharge cells belonging to the scanning line Ln based on the ON-state image data. . In such a case, since the write discharge current flowing through each bus electrode 102 of the electrodes Xn and Yn is large, the voltage drop (voltage drop within the lead) due to the lead resistance of the bus electrode 102 is very large. At this time, the largest voltage V for starting the address discharge
In each discharge cell for green light emission requiring cg, in addition to the lag of the address discharge caused by the above-described order of the color (1), the voltage drop in the bus electrode 102 causes
Since the voltage applied to the discharge cell or the discharge space is substantially smaller than the externally applied voltage Vx, (−Vy), the address discharge is more difficult to occur as compared with the discharge cells or the discharge spaces of other luminescent colors.

As a method for solving such a situation and realizing a stable address discharge of the discharge cell for emitting green light, a voltage (Vo) externally applied between the electrodes Am and Yn is used.
n + Vy) may be set to a value sufficiently higher than the voltage Vcg.

In order to realize this method, the voltage Von
May be set higher than the conventional value. However, as the voltage Von increases, the potential difference between the voltage Von based on the image data in the ON state and the voltage Voff based on the image data in the OFF state (= Von−Voff).
Becomes larger, so that the load on the drive IC for the address electrode increases. Therefore, a method of solving the above situation by increasing the set value of the voltage Von is not preferable in terms of power consumption.

On the other hand, if the voltage Voff is increased in conjunction with the increase in the voltage Von, the above-described increase in power consumption can be suppressed. However, when the voltage Voff is increased, the voltage Voff based on the OFF-state image data is increased.
In the discharge cell to which is applied, the set potential difference (Voff + Vy) between the electrodes Am and Yn becomes larger, so that an erroneous write discharge may occur.

For example, as shown in FIG.
When each of the discharge cells of (m-1), (n, m), and (n, m + 1) is a discharge cell for emitting blue light, emitting red light, or emitting green light, among all the discharge cells belonging to the scanning line Ln, Consider a case where an address discharge is generated only in two discharge cells, that is, a discharge cell for emitting blue light at address (n, m-1) and a discharge cell for emitting green light at address (n, m + 1) (accordingly,
Address discharge is not performed in other light emitting cells belonging to the scanning line Ln). At this time, the bus electrode 10 of the scanning electrode Yn
Since the discharge current flowing through 2 is small, there is almost no voltage drop in scan electrode Yn or bus electrode 102. Therefore, (i) the potential difference between the electrodes Am and Yn in the discharge cell for red light emission at the address (n, m) is substantially equal to the voltage (Vo).
ff + Vy). On the other hand, (ii) the address electrode Am
Is applied with a voltage Voff, and a voltage Von is applied to each of the address electrodes Am-1 and Am + 1.
Through 07, the electric field intensity in the discharge space 151S corresponding to the electrode Am is increased. At this time, in view of the above-mentioned conditions (i) and (ii) and the relational expression of the above-mentioned expression (1), for example, in the discharge cell for red light emission at the address (n, m), erroneous writing is particularly likely to occur. It can be said that there is a situation.

The above-mentioned erroneous write discharge is caused by the voltages Von, Vy
Can be avoided by setting. However, if such a voltage setting is performed, the voltage (Von) between the electrodes Am and Yn applied for the address discharge is set.
+ Vy) becomes small, so that stable discharge of the discharge cell for green light emission is not realized, and the initial problem is caused again.

As described above, in the conventional AC type PDP 151, due to the difference in the material (characteristic) for each emission color of the phosphors 108R, 108G, 108B, each voltage Vo
The adjustment width or margin of the voltage values of n, Voff and Vy is narrow. For this reason, it is difficult to generate a stable address discharge over the entire PDP. Therefore, in the conventional PDP 151, the light emitting cells to be lit during the sustain period do not light (non-light), or the light emitting cells that should not be lit during the sustain period. There is a problem in display quality that it is lit (erroneously lit).

Problem: The balance of the emission intensity of each of the red (R), green (G) and blue (B) emission colors is not sufficient.

In the PDP, white light is displayed by causing all the light emitting cells of each of the red (R), green (G), and blue (B) to emit light. However, in the conventional PDP 151, the white color coordinates (x, y) when the above-described white light emission is performed show a large deviation from the optimal value (x0, y0). This gap is
This is caused by the fact that the emission intensity per predetermined unit intensity of discharge is different for each phosphor material of each emission color, and the main cause is an imbalance of the emission intensity of each emission color. Therefore, by correcting the above-described imbalance of the light emission intensity, white light emission having the optimum value (x0, y0) can be realized. At this time, for example, the emission intensities Ir, Ig, I of the red (R), green (G), and blue (B) emission colors, respectively.
When b has a relationship of Ib <Ir <Ig (2), as an example of the correction means, the emission intensity of green emission (G) with respect to the emission intensity of red emission (R) is reduced. In addition, there is a method of increasing the emission intensity of blue emission (B) with respect to the emission intensity of red emission (R). However, such a method is not adopted in a conventional general AC-type PDP because the realization of the configuration is complicated.

As another means for correcting the above-mentioned imbalance of the light emission intensity, there is a method of adjusting the gain for each light emission color using a gradation display (a conventional general AC type PDP).
Adopts this correction method). Here, as an example of a gradation display control method, for example, a video display time (one frame) for one screen is divided into eight subfields (SF), and selection / non-selection of the eight subfields is performed. Alternatively, there is a method of performing 256 gradations from rank 0, which is the lowest luminance (no light emission in all subfields), to rank 255, which is the highest luminance (light emission in all subfields), by a combination of light emission / non-light emission. . Therefore, in the conventional AC PDP, each of the red (R), green (G), and blue (B) ranks is set so that the white display in this gradation display control method matches the chromaticity coordinates (x0, y0). The imbalance of the light emission intensity described above is corrected by adjusting the gain or each gain. For example, when there is a relationship of the above-described formula (2) between the emission intensities Ir, Ig, and Ib of the respective emission colors, the rank of the green emission (G) is lowered with respect to the rank of the red emission (R), and the red emission (R) is reduced. The above correction is implemented by increasing the rank of blue light emission (B) relative to light emission (R). At this time, the adjustment of the ranking is performed by signal processing of the image data.

However, in the correction method using the gain adjustment, it is difficult to realize an optimal white display unless a considerably large rank difference is set between the emission colors. For this reason,
The total number of ranks of green light emission (G) and red light emission (R) is smaller than the total number of ranks of blue light emission (B) (for example, 256 gradations). That is, AC using gain adjustment
The type PDP has a smaller number of gradations of green light emission (G) and red light emission (R) than an AC type PDP that does not employ the correction method, that is, the gradation level of the AC type PDP is lower. I will.

As described above, the conventional AC type PDP has a problem that the emission intensity of each emission color of the display emission during the sustain period is not sufficient due to the difference in the phosphor material for each emission color. Have.

Problem: The luminance at the center in the longitudinal direction of the scanning line in the display area is lower than at both ends.

The electrodes Xn, Y explained in the above-mentioned problem
The voltage drop in the lead at each of the n bus electrodes 102 may also occur during the sustain period.

In general, the bus electrode 102 is connected to a terminal which is formed at an end outside the display area and is a supply point of an external voltage. Therefore, when a predetermined voltage is supplied to the bus electrode 102, a voltage drop having a different magnitude occurs in the second direction D2 (or the lead direction) which is the longitudinal direction of the bus electrode 102. That is, since the shape and dimensions of the bus electrodes 102 of the electrodes Xn and Yn are the same in all the discharge cells, a voltage distribution occurs in which the voltage drop increases as the distance from the terminal to which the external voltage is applied increases.
Corresponding to such a voltage distribution, among the light emitting cells (plurality) belonging to the scanning line, the light emitting cell located farther from the terminal has lower luminance. That is, a luminance distribution occurs along the longitudinal direction of the scanning line. At this time, as shown in FIG. 20, generally, an external voltage is supplied to the electrode Xn and the electrode Yn from respective terminals provided at different ends. For this reason, when a predetermined AC sustaining voltage is applied to both electrodes during the sustaining period, the light emission luminance of the light emitting cell located at the center in the longitudinal direction of the scanning line as an image display of the entire PDP is increased at both ends. It is observed lower than the light emission luminance of the light emitting cell located.

The bus electrodes 1 of both electrodes Xn and Yn
In the case where the terminal 02 is formed only at one end of the PDP or the front glass substrate 105, a luminance distribution in which the emission luminance at the other end is lower is observed.

As described above, since the widths of the bus electrodes 102 have the same shape and size, a problem is caused in that a luminance distribution is generated in the display area, that is, the display quality of the AC type PDP is deteriorated. You. In particular, when the luminance at the center of the display area is low, the entire display area is visually perceived to be dark, so that the deterioration of the display quality becomes more apparent.

Accordingly, it is a primary object of the present invention to solve the above-mentioned problems (1) to (4) and to provide an AC plasma display panel or an AC plasma display device having excellent display quality. And in order to achieve such a main object, the present invention has the following more detailed objects.

First, the present invention provides an AC plasma display panel and a method of driving the AC plasma display panel which can generate more stable address discharge by expanding the adjustment width or margin of each of the voltages Von, Voff and Vy. This is the first object.

The second object is to provide

A third object of the present invention is to provide an AC plasma display panel in which the luminance distribution in the longitudinal direction of the scanning line is eliminated and a method of driving the AC plasma display panel.

Further, a fourth object of the present invention is to provide an AC type plasma display panel which can constitute an AC type plasma display panel which can realize the above first to third objects by being applied to the AC type plasma display panel. An object of the present invention is to provide a panel substrate.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Before describing the embodiments of the present invention, the prerequisite technology will be described.

(Base Technology) As a base technology, an AC type PD
An example of a method of driving P will be described. The driving method according to the base technology is proposed in Japanese Patent Application No. 9-173962.

In the driving method of the AC type PDP according to the base technology, a video display time for one screen is divided into a plurality of fields as a driving method for displaying a color image. Here, as shown in FIG. 1, a case where a color image of 256 gradations is obtained by dividing a video display time for one screen into eight subfields SF1 to SF8 will be described.

Each of the subfields SF1 to SF8 further includes an erasing operation period or erasing period RA or RB for erasing the light emission history in the immediately preceding subfield, and the light emission / emission of the light emitting cells in the subfield.
A write operation period or address period AD for selecting non-light emission and a sustain operation period or sustain period S for executing discharge / non-discharge a predetermined number of times according to the state selected in the immediately preceding address period AD. Has been split.
At this time, the sustain periods S of the subfields SF1 to SF8 are ranked for each of the subfields SF1 to SF8. For example, the time of the sustain period S in the subfield SF2 is the time of the sustain period S in the subfield SF1. Is set almost twice as large as That is, the duration of the sustain period S of the subfield SF (N + 1) is set to approximately twice that of the subfield SFN (N: 1 to 7).

In the light emitting cells or discharge cells selected in the address period AD of each subfield, the sustain pulse applied during the sustain period S generates the same number of sustain discharges as the number of the sustain pulses. Visible light emission generated by the sustain discharge becomes display light emission of the light emitting cell. As described above, since the number of the sustain pulses is set so as to be substantially proportional to the time of the sustain period S of each of the subfields SF1 to SF8, the light emission luminance of the light emitting cell selected by the write operation in the address period AD. Almost doubles as the subfield number advances by one. Therefore, by controlling the combination of lighting / non-lighting (ON state / OFF state of the light emitting cell) in the sustain period S in each subfield, two light emitting cells in one light emitting cell are controlled.
⁸ = 256 levels of light emission luminance, that is, display light emission of 256 gradations can be obtained.

Next, a more specific driving method in one subfield will be described with reference to the timing charts of FIGS. Here, the conventional AC shown in FIG.
The case where the type PDP 151 or the conventional plasma display device 100 of FIG. 20 is used will be described. In each of FIGS. 2 and 3, (a) shows an address electrode Am corresponding to a predetermined address electrode 106 of M lines in FIG.
(1 ≦ m ≦ M), (b) is a timing chart of the sustain electrode X (N sustain electrodes Xn are commonly connected and a single voltage is applied),
Each of (c) to (e) is a predetermined scanning electrode Yn of N lines.
It is a timing chart of (1 <= n <= N). Each of the subfields shown in FIGS. 2 and 3 has an erasing period RA or an erasing period RB, respectively.

In each address period AD of FIGS. 2 and 3,
By sequentially applying a voltage (-Vy) to the scanning electrodes Yn, an n-th scanning line Ln composed of an electrode pair Xn and Yn is applied.
(See FIG. 19).
At this time, a voltage Von / voltage Voff based on the ON state / OFF state of the image data is applied to the address electrode Am in synchronization with the application of the voltage (−Vy). Further, a predetermined voltage Vx is applied to sustain electrode X. In the discharge cell in which the voltage Von is applied to the address electrode Am, an address discharge occurs, and the image data is written (as wall charges) in the light emitting cell. On the other hand, in the light emitting cell in which the voltage Voff is applied to the address electrode Am, the address discharge does not occur.

In the subsequent sustain period S, an AC sustain pulse or a sustain voltage Vs is applied between the sustain electrode Xn and the scan electrode Yn. At this time, the discharge cells that have caused the address discharge in the above-described address period AD are:
Sustain discharge occurs according to the timing when the above-mentioned sustain pulse Vs is applied.

Here, with reference to FIGS. 4 and 5, a description will be given of a mechanism for generating a write discharge in the address period AD. When the voltage Vx and the voltage (−Vy) are applied to each of the electrodes Xn and Yn, the upper discharge space 15 between the electrode pair Xn and Yn is applied.
An electric field is generated in 1S. However, such an electric field alone does not have an electric field intensity necessary for generating a surface discharge between the pair of electrodes Xn and Yn. In this state, when the voltage Von based on the image data in the ON state is applied to the address electrode Am, a strong electric field is generated between the address electrode Am and the scan electrode Yn, and as shown in FIG. Am, Yn
A (discharge) facing discharge DC1 occurs between the two. Then
The charged particles generated by the opposed discharge DC1 serve as a trigger to generate a (writing) surface discharge DC2 between the pair of electrodes Xn and Yn, as shown in FIG.

The negative or positive charged particles generated by the surface discharge DC2 are attracted to the electrodes Xn and Yn having polarities opposite to the polarities of the particles, respectively.
Is stored as wall charges on the surface 104S of the cathode film 104 above. At this time, the wall charges are generated in the discharge space 15.
Since the electric field formed in 1S acts in a direction in which the voltage applied between the electrode pair Xn and Yn cancels the electric field formed in the discharge space 151S, the amount of charged particles attracted to the surface 104S gradually decreases. Then, when the accumulation amount of the wall charges reaches a certain amount, the address discharge surface discharge DC2 between the electrode pair Xn and Yn ends. At this time, the electrodes Xn, Y
Even after the supply of voltage to n is stopped, the wall charges accumulated on the surface 104S of the cathode film 104 remain without being eliminated. Then, the sustain period S following the address period AD
, A sustain discharge (surface discharge) between the electrode pair Xn and Yn
In the discharge space 151S. By the action of the wall charges, the voltage Von
Are emitted in the sustain period S.

On the other hand, in the discharge cell in which the voltage Voff based on the OFF image data signal is applied to the address electrode Am in the address period AD, the address electrode Am
A sufficient electric field is not generated between the pixel and Yn to generate the write facing discharge DC1. Therefore, the address electrode A
m and the scanning electrode Yn do not generate the write facing discharge DC1. Therefore, the writing surface discharge DC1 between the electrode pair Xn and Yn does not occur.
No 2 occurs. As a result, the discharge cell to which the voltage Voff is applied shifts to the sustain period S while the above-described wall charges are not formed, so that no sustain discharge occurs in the sustain period S. That is, the discharge cell does not emit light.

In the sustain period S, a positive voltage Va is supplied to all the address electrodes Am as shown in FIG. 2A and FIG. 3A. As described above, in the address period AD, wall charges are formed on the surface 104S of the cathode film 104. At this time, the overglaze layer 110 and the phosphor layer 108 are also slightly negatively charged. For this reason, the potential of the space near the portion of the phosphor layer 108 in contact with the overglaze layer 110 is changed by the applied voltage Va to the average potential of the space above the center axis of the internal gap G (approximately, the voltage (Vs / 2) ) + The potential exerted by the positive and negative wall charges). By supplying the voltage Va to the address electrode Am, even when the voltage Vs is applied to any of the electrodes Xn and Yn, the electric field intensity distribution having spatial symmetry with respect to the center axis of the internal gap G is obtained. It can be generated in the discharge space near G. As a result, according to the driving methods shown in FIGS. 2 and 3, the voltage for starting the discharge applied between the electrode pair Xn and Yn can be reduced, and the efficiency of the sustain discharge can be improved. The voltage Va is set so that the discharge intensity per sustain discharge (surface discharge) between the electrodes Xn and Yn is maximized.

An embodiment of the present invention will be described below. Unless otherwise specified, it is assumed that the materials and the shape dimensions of the respective red, green and blue phosphors in each AC type PDP are the same as those of the conventional PDP 151 (see FIG. 19). In addition, the materials of the constituent elements of the light emitting cell or the discharge cell (however, the fluorescent material is different for each light emission color), the shape and dimensions, and the voltage applied to each electrode are changed in the same manner as those according to the prior art and the base technology. (I)
It is assumed that the difficulty level of the generation of the address discharge in the discharge cells of each emission color includes an order of red light-emitting cells, blue light-emitting cells, and green light-emitting cells in the order of occurrence of the address discharge.
i) In order to obtain an optimum chromaticity in white light emission, blue light emission is increased relative to red light emission intensity,
In addition, it is necessary to reduce green light emission. It will be apparent from the following description that the description under such assumptions (i) and (ii) does not lose generality.

On the surface 3S on the 1S side, a cathode film 4 made of a high secondary electron emission material such as magnesium oxide (MgO) is formed. The dielectric layer 3 and the cathode film 4 can be generically referred to as "dielectric layer 3A" from the viewpoint of their materials. At this time, “the surface 3SA of the dielectric layer 3A” means
The surface 4S of the cathode film 4 on the side of the discharge space 51S corresponds to this.

On the other hand, the first substrate (substrate for AC type plasma display panel) 51Ra is a rear glass substrate 9

More specifically, the rear glass substrate 9 is arranged so that its surface 9S is perpendicular to the third direction D3. On the surface 9S of the rear glass substrate 9, three types of band-shaped address electrodes 6Ra, 6Ga, and 6Ba (also collectively referred to as "address electrodes 6a") having different widths are provided in the second and third directions D2 and D3, respectively. It is formed along a first direction D1 perpendicular to both of D3. M address electrodes 6Ra, 6Ga, and 6Ba are formed as a total of the entire PDP 51a. Here, the width of the address electrode, which is a strip-shaped electrode, refers to the length and length dimension along the second direction. In particular,
In the PDP 51a, the address electrodes 6Ra, 6Ga, 6B
a between the respective lengths of the widths 6WRa, 6WGa, and 6WBa (the lengths are also denoted by the same reference numerals), and 6WRa <6WBa <6WGa (3) The relationship is prescribed. The order of the equation (3) will be described later in detail. The widths 6WRa, 6WGa, and 6WBa are collectively referred to as “width 6

An overglaze layer or a glaze layer 10 made of a dielectric is formed so as to cover the address electrodes 6a and the surface 9S of the rear glass substrate 9 (corresponding to the overglaze layer 110 in FIG. 19).

Further, a plurality of barrier ribs 7 are formed on a region where the region between adjacent address electrodes 6a is projected on the surface 10S of the overglaze layer 10 opposite to the surface 9S.

The phosphor layer 8R is disposed above Ra, and the address electrode 6
The phosphor layer 8G is disposed above the Ga, and the address electrode 6
The phosphor layer 8B is arranged above Ba. Conversely, in the PDP 51a, address electrodes 6Ra, 6Ga, and 6Ba having different widths 6WRa, 6WGa, and 6WBa are arranged for the respective emission colors of the phosphor layers 8R, 8G, and 8B. In the following description, the phosphors (layers) 8R, 8G, and 8B of each emission color are collectively referred to as “phosphor (layer) 8”.
Also called. In addition, the surface of each of the phosphors (layers) 8R, 8G, and 8B in contact with the discharge space 51S or the surface 3

As described above, the PDP 51a operates in the first
The substrate 51Ra and the second substrate 51F are arranged via the barrier rib 7. At this time, the address electrodes 6Ra,
Each width 6WRa, 6WGa, 6WBa of 6Ga, 6Ba
Are set based on the emission colors of the phosphors 8R, 8G, and 8B belonging to each section when the base element is sectioned in units of address electrodes. In other words, each section of the base element is not all the same, and has a predetermined structure set based on each emission color.

When expressing the correspondence or belonging of the components constituting the AC type PDP 51a, for example, "address electrode (or fluorescent material) corresponding to (belonging to) the discharge space" means "first direction D1". The address electrodes (or phosphors) belonging to the relevant section of the base element contacting a predetermined discharge space formed along the line. Furthermore,
For example, the expression "phosphor corresponding to (belonging to) the address electrode" refers to the correspondence between the address electrode and the phosphor which belong to the same section of the base element. This applies to Embodiments 2 to 10 described later.

The width is set larger. That is, as shown in FIG. 6, the width 6WGa of the address electrode 6Ga is set to be the largest, and the width 6WRa of the address electrode 6Ra is set to be the smallest. Therefore, when the driving method according to the above-described prerequisite technology is applied to the PDP 51a, for example, a voltage (-Vy) having the same voltage value is supplied to all the scan electrodes Yn in the address period AD, and Voltage Von / Vo having the same voltage value on all address electrodes 6a
The probability of occurrence of the address discharge when ff is supplied can be made substantially uniform in all the discharge cells. That is, it is possible to cancel the order of the occurrence or the difficulty of the address discharge different for each light emission color, which the conventional PDP 151 has. Therefore, the voltages Von, Voff,
The adjustment width (margin) of each voltage value of Vy can be made wider than that of the conventional AC PDP 151. as a result,
In the PDP 51a driven by appropriately set voltages Von, Voff, (−Vy), the erroneous write discharge is reduced or eliminated as compared with the conventional PDP 151. This makes it possible to obtain a high-quality image display in which non-lighting and false lighting during the sustain period are reduced or eliminated.

(Embodiment 2) FIG. 7 shows an AC type PDP 51b (hereinafter simply referred to as "PDP 51b") according to Embodiment 2.
FIG. 2 is a vertical cross-sectional view schematically showing the structure of FIG. In particular, the PDP 51b is characterized by an address electrode 6b to be described later, and the following description will focus on such points. Other basic components are the PDP according to the first embodiment.
Since the same thing as 51a is applicable, PDP 51
The same reference numerals are given to the same components as those of the component a, and the description thereof is referred to.

As shown in FIG. 7, the PDP 51b has a first substrate 5 corresponding to the above-described first substrate 51Ra (see FIG. 6).

Instead of 6Ga and 6Ba, the surface 9 of the back glass substrate 9
Address electrodes 6Rb, 6Gb, 6Bb are arranged on S. Specifically, three types of band-shaped address electrodes 6Rb, 6Gb, and 6B having different widths are formed on the surface 9S.
b (generically referred to as “address electrodes 6b”) are arranged along the first direction D1. Address electrode 6Rb,
M lines of 6Gb and 6Bb are arranged as a total of the entire PDP 51b. In particular, in the PDP 51b, the widths 6WRb, 6W of the address electrodes 6Rb, 6Gb, 6Bb respectively.
Gb, 6WBb (Length dimensions are also denoted by the same reference numerals)
The order or magnitude relation of 6WBb <6WRb <6WGb (4) is defined between the lengths of The widths 6WRb, 6WGb, and 6WBb are collectively referred to as “width 6Wb”.
Also called. Further, as in the first embodiment, a predetermined one of the M address electrodes 6Rb, 6Gb, 6Bb is also referred to as “address electrode Am” (1 ≦ m ≦ M).

As shown in the above equation (4), the PDP 51b
In the conventional PDP 151, the width of an address electrode belonging to an emission color having a higher emission intensity per unit discharge intensity in the conventional PDP 151 is set to be larger. That is, in the conventional PDP 151 shown in FIG.
6 have the same width, whereas the PDP 51b according to the second embodiment has the address electrode 6G belonging to the green light emitting cell having the highest light emission intensity per unit discharge intensity.
The width 6WGb of b is the largest, and the width 6WBb of the address electrode 6Bb belonging to the light emitting cell for blue light emission having the weakest light emission intensity per unit discharge intensity is set the smallest.

That is, the first substrate 51Rb is disposed so as to cover the rear glass substrate 9 and the surface of the address electrodes 6Rb, 6Gb, 6Bb and the address electrodes 6Rb, 6Gb, 6Bb that do not face the surface 9S of the rear glass substrate 9. Overglaze layer 10 and address electrodes 6Rb, 6G
phosphors 8R, 8G, 8B arranged along b, 6Bb

b, 6WBb are not the same when the base element is divided in units of address electrodes, and are set based on the emission colors of the phosphors 8R, 8G, 8B belonging to the respective divisions.

When the voltage Va is applied to the address electrode during the sustain period S of the driving method according to the base technology, the electric field formed by the voltage Va changes the internal gap G.
(See FIG. 4, FIG. 5, or FIG. 19.) The influence or distortion on the electric field of the nearby discharge space 51S is larger as the width of the address electrode is larger. Therefore, when the driving method according to the base technology is applied to the PDP 51b, the magnitude of the electric field distortion is in the order corresponding to the above-described equation (4), that is, (the discharge cell to which the address electrode 6Gb belongs)> ( Discharge cell to which address electrode 6Rb belongs)> (discharge cell to which address electrode 6Bb belongs). That is, according to this order, the electric field strength between the electrodes Xn and Yn (accordingly, the discharge intensity) in each discharge cell or discharge space 51S is weakened as the electric field distortion increases, so that the electrodes Xn and Y
It is possible to cancel the difference in the light emission intensity among the phosphors 8G, 8R, 8B with respect to the discharge intensity per one surface discharge between n. Therefore, according to the PDP 51b, unlike the conventional PDP 151, the optimum white chromaticity is realized without performing a large gain adjustment for each emission color (that is, while ensuring the maximum number of gradations). , High-quality image display is possible.

In the driving method according to the prerequisite technique, the voltage Va set so that the discharge intensity per sustain discharge (surface discharge) between the electrodes Xn and Yn is the highest is set to PDP.
When applying the driving method according to the base technology to 51b,
The voltage is adjusted to a voltage suitable for the PDP 51b and applied.

First, the address electrode 6Rc is formed with its thickness or height controlled to 10 μm (preferably 10 μm or more). Here, the thickness or height of the address electrode refers to a length dimension along the third direction D3.
When the address electrode 6c is formed by, for example, a sand blast method or the like, as shown in FIG. 8, the cross section of the address electrode 6c perpendicular to the first direction D1 is square. On the other hand, the address electrodes 6 are formed using a screen printing method.
When c is formed, the cross section becomes a rounded shape (the definition of the width and the thickness is applied as it is even in such a case).

Then, the lower overglaze layer 10Lc
Is formed as follows. First, a glass paste as a raw material is applied to the address electrodes 6R by screen printing.

The properties of the glass paste, such as viscosity, fluidity, surface tension, etc., are controlled so as to achieve the desired results. Here, the thickness of the glass paste or the lower overglaze layer or the dielectric layer 10Lc on the address electrode 6Rc refers to the surface 6 of the address electrode 6Rc.
The length of the glass paste or the like in contact with SRc in the third direction D3 is referred to.

At a position depressed by μm, there is a portion of the surface 10SLc other than the projection portion of the address electrode 6Rc.

Subsequently, the lower overglaze layer 10Lc
Similarly, a middle overglaze layer 10Mc having a thickness on the address electrode 6Bc of about 6 μm is formed. At this time, on the exposed surface on the surface 9S side of the rear glass substrate 9,
The projected portion of the address electrode 6Bc on the surface 10SMc of the middle overglaze layer 10Mc protrudes most in the third direction D3. The projection of the address electrode 6Rc in the surface 10SMc is located at a position recessed by about 3 μm from the projection. Further, at a position depressed by about 4 μm, there is a portion of the surface 10SMc except for the projected portion of the address electrodes 6Bc and 6Rc.

Further, the address electrode 6R is provided at a predetermined position on the surface 10SMc of the middle overglaze layer 10Mc.
Similarly to c and 6Bc, an address electrode 6Gc having a thickness of about 10 μm is formed. At this time, on the exposed surface on the surface 9S side of the rear substrate 9 after the formation of the address electrode 6Gc, the surface 6SGc of the address electrode 6Gc is moved in the third direction D3.

[Table 1]

In the conventional PDP 151 (see FIG. 19),
Generally, the thickness of the overglaze layer 110 on the address electrode 106 and the discharge space 151S above the electrode 106
Are about 10 μm and about 100 μm, respectively.
The relative dielectric constant of (the dielectric material of) the overglaze layer 10 is several times to several tens times larger than that of the discharge space 151S (the discharge gas filled therein). Based on these,
When the driving method according to the base technology is applied to the AC type PDP 51c of FIG. 8, the above two electrodes required to generate a write facing discharge between the address electrode and the scan electrode in the address period AD. The potential difference between them was determined by a simple electric field calculation. According to this calculation, it was found that when the thickness of the overglaze layer increased by 10 μm or when the thickness of the discharge space increased by 1 μm, the potential difference increased by about 1% (converted to a voltage of about 2 V). At this time, according to Table 1, each discharge cell to which each of the address electrodes 6Rc and 6Bc belongs has a voltage of about 15 V, about 15 V, compared to the discharge cell to which the address electrode 6Gc belongs (or the discharge cell in the conventional PDP 151). Address discharge is less likely to occur for 8V. That is, by controlling the thickness of the overglaze layer on the address electrode or the thickness of the discharge space above the electrode, the order of difficulty in generating the address discharge corresponding to the difference in the emission color in the conventional PDP 151 is determined. It is possible to cancel.

The PDP 51c according to the third embodiment includes a back glass substrate 9 and address electrodes 6Rc, 6Gc, 6G.
The surface 6SRc of Bc and the address electrodes 6Rc, 6Gc, 6Bc not facing the surface 9S of the back glass substrate 9;

and a base element composed of phosphors 8R, 8G, and 8B arranged along the first substrate 51Rc. In particular,
The overglaze layer 10c has the surface 6WRc, 6WG
In the third direction D3, the thickness of the portion covering c, 6WBc is not the same when the base element is divided in units of address electrodes. It is set based on the emission color. Thereby, the thickness of the overglaze layer 10c on the address electrode 6c is controlled (the thickness of the discharge space above the electrode is also controlled due to the surface unevenness of the overglaze layer 10c).

Therefore, the AC type PDP according to the third embodiment
According to 51c, the adjustment width (margin) of each voltage value of the voltages Von, Voff, and Vy can be made wider than that of the conventional PDP 151. As a result, the PD driven by the appropriately set voltages Von, Voff, (−Vy)
In P51a, the erroneous write discharge is reduced or eliminated as compared with the conventional PDP 151. This makes it possible to obtain a high-quality image display in which non-lighting and false lighting during the sustain period are reduced or eliminated.

(Embodiment 4) FIG. 9 shows an AC type PDP 51d according to Embodiment 4 (hereinafter simply referred to as "PDP 51d").
FIG. 2 is a vertical cross-sectional view schematically showing the structure of FIG. In particular, since the PDP 51d is characterized by an address electrode 6d and an overglaze layer 10d, which will be described later, the following description will focus on such points. Other basic components can be the same as the above-described PDPs 51a, 51b, and 51c, so that the PDPs 51a, 51b, and 51c

As shown in FIG. 9, the PDP 51d is different from the PDP 51d in that the formation surfaces of the address electrodes 6Rd, 6Gd, and 6Bd are different corresponding to the emission colors of the phosphors 8R, 8G, and 8B disposed above the PDP 51d. , PDP 51c of FIG.

In detail, on the front surface 9S of the rear glass substrate 9, a predetermined area corresponding to the area where the arrangement position of the address electrode 6Bc in FIG. Corresponding band-shaped address electrode 6B

Then, a lower overglaze layer 10Ld corresponding to the lower overglaze layer 10Lc in FIG. 8 is formed so as to cover the surface 6SBd, which is a portion of the surface 9S and the surface of the address electrode 6Bd that is not in contact with the surface 9S. ing.

A middle overglaze layer 10Md corresponding to Mc is formed.

Further, on the surface 10SMd of the middle overglaze layer 10Md opposite to the surface 9S,
A band-shaped address electrode 6Gd corresponding to the address electrode 6Gc is formed along a first direction D1 in a predetermined area corresponding to an area where the arrangement position of the address electrode 6Gc in FIG. 8 is projected on the front surface 10SMd. .

At this time, like the PDP 51c, M address electrodes 6Rd, 6Gd and 6Bd are formed as a total of the entire PDP 51d, and M address electrodes 6Rd and 6B are formed.

Ld, 10Md, and 10Ud are also collectively referred to as “overglaze layer 10d”. At this time, the “surface 10Sd” of the overglaze layer 10d refers to the surface 10Sud of the upper overglaze layer 10Ud on the opposite side to the surface 9S.
Is applicable.

As shown in FIG. 9, A according to the fourth embodiment
In the C-type PDP 51d, the thickness of the portion of the dielectric layer 10d disposed on the surface 6SGd of the address electrode 6Gd for green light emission is set to the minimum, and the thickness of the dielectric layer 10d is reduced.
d of the surface electrodes 6SB of the address electrode 6Bd for emitting blue light
The thickness of the portion arranged on d is set to the maximum. Correspondingly, the discharge space 51 in the light emitting cell of each light emitting color
The thickness of S is (green light emitting cell) <(red light emitting cell)
<(Blue light emitting cell).

For this reason, when the driving method according to the base technology is applied to the PDP 51d, the address electrode A is not applied during the sustain period S.
The electric field distortion in the discharge space near the internal gap G (see FIG. 4, FIG. 5, or FIG. 19) of the electrode pair Xn, Yn induced by the voltage Va (see FIG. 2 or FIG. 3) applied to m. Control is possible for each color discharge cell (however, the conventional PDP1
At 51, the voltage Va set so as to maximize the discharge intensity per one sustain discharge between the electrodes Xn and Yn is appropriately adjusted). That is, in view of the fact that the smaller the thickness of the overglaze layer 10d on the address electrode Am or the thickness of the discharge space 51S, the larger the electric field distortion, the PD
In P51d, regarding the thickness of the discharge space 51S, (green light emitting cell) <(red light emitting cell) <(blue light emitting cell)
Corresponding to the order, there is a magnitude relationship of (blue light emitting cell) <(red light emitting cell) <(green light emitting cell) regarding the magnitude of the electric field distortion for the same voltage Va. Since the discharge intensity of the sustain discharge in the sustain period S between the electrode pair Xn and Yn decreases as the electric field distortion increases, the conventional PDP 151 (see FIG. 19) is the same for all emission colors. (Green light emitting cell) <(red light emitting cell) <(blue light emitting cell). Therefore, PDP
According to 51d, it is possible to cancel the difference in the light emission intensity among the phosphors 8G, 8R, 8B with respect to the discharge intensity per discharge between the electrodes Xn, Yn. That is, according to the PDP 51d according to the fourth embodiment, the conventional PDP 1
Unlike 51, the optimum white chromaticity is realized without a large gain adjustment for each emission color (that is, while securing the maximum number of gradations), and a high-quality image display is possible. is there.

(Modification 1 of Embodiments 3 and 4) The effects of the above-described Embodiments 3 and 4 depend on the thickness of the overglaze layer on the address electrode or the thickness of the discharge space above the address electrode. Is set for each emission color. In view of this, all the address electrodes are arranged on the same forming surface such as the surface 9S of the rear glass substrate 9 and the thickness of the overglaze layer covering the address electrodes is controlled for each emission color. When the thickness of the discharge space for each emission color is appropriately set, the above-described effect can be obtained.

In this case, as the thickness of the overglaze layer 10 having a relative dielectric constant larger than that of the discharge space becomes larger (the thickness of the discharge space becomes smaller by that amount), the voltage or electric field applied to the address electrode is reduced by the internal gap G. The influence on the electric field in the nearby discharge space increases. Therefore, in such a structure, when the thickness of the overglaze layer is in the order of (overglaze layer for green) <(overglaze layer for blue) <(overglaze layer for red), the same as the AC type PDP 51c of FIG. The effect of can be obtained. When the order of (overglaze layer for green)> (overglaze layer for red)> (overglaze layer for blue) is given in relation to the thickness of the overglaze layer, the AC PDP 5 shown in FIG.
The same effect as 1d can be obtained.

According to the AC type plasma display device having the AC type PDP according to each of the above-described first to fourth embodiments and the first modification of the third and fourth embodiments, the above-described effects are exhibited, and Image display of higher quality than that of the PDP 151 can be obtained.

(Embodiment 5) Embodiments 1 to 4 described above.
Then, AC-type PDPs 51a, 51b, 51c, 51d having a new structure capable of solving the above-mentioned problems or problems can be solved.
Suggested. In the fifth embodiment, for example, a conventional AC type P
By applying the present invention to the DP 151, a new driving method capable of solving the above problem is proposed. Of course, such a driving method is applied to the AC type PDPs 51a, 51b, 51c, and 5 described above.
It may be used for 1d.

In particular, the present driving method is characterized by a driving method in the address period corresponding to the address period AD in the driving method according to the base technology. Each driving method in the erase period and the sustain period is as follows:
The respective driving methods in the erasing periods RA and RB and the sustain period S according to the base technology can be applied.

FIG. 10 is a timing chart of the voltage applied to the address electrode during the address period AD1 in the driving method according to the fifth embodiment. (A-
1) is the M address electrodes Am of the PDP 151
Of the plurality of address electrodes formed below the red light-emitting phosphor layer (on the rear glass substrate side) and applied to the j-th or j-th address electrode (hereinafter, referred to as “address electrode AjR”) 6 is a timing chart of a voltage to be applied. Similarly, (a-2) and (a-3) in FIG.

At this time,
Timing charts of voltages applied to the sustain electrodes X and the like in the address period AD are shown in FIG.
(E) is applicable. The address electrodes AjR, AjG, AjB having the same suffix j in the code are arranged adjacent to each other and constitute one pixel composed of three light emitting cells emitting red, green and blue light emission colors. ing.

In the driving method according to the fifth embodiment, the ON / OFF state of the image data in the address period AD1.
The voltage based on the state (voltage Von / V in FIG. 2 or FIG. 3)
off), that is, for each emission color, that is, address electrode AjR, address electrode AjG, address electrode AjB.
A voltage having a different voltage value is applied every time.

Specifically, as shown in FIG. 10, a (first) voltage Von / (second) voltage is applied to each of the address electrodes AjR, AjG, AjB based on the ON state / OFF state of the image data. Voff (see FIG. 2 or FIG. 3) is calculated by dividing (first) voltage VonR / (second) voltage Voff
R, (first) voltage VonG / (second) voltage VoffG,
When (first) voltage VonB / (second) voltage VoffB (each voltage value is also represented by the same reference numeral) (assuming these are collectively referred to as voltage Von / Voff), VonG ≧ VonB ≧ VonR (5-1) VoffG ≧ VoffB ≧ VoffR (5-2) The magnitude relationship is set as follows. That is, the conventional PDP 151
In light emitting cells provided with a phosphor for green light emission in which both regular address discharge and erroneous address discharge hardly occur, other voltages VonR / VoffR and VonB
Each voltage VonG / VoffG having a voltage value relatively higher than / VoffB is applied to the address electrode AjG in the address period AD1. On the other hand, conventional PDP1
At 51, the light emitting cell including the red light emitting phosphor in which both the normal address discharge and the incorrect address discharge are likely to occur is supplied with another voltage VonG / VoffG and a voltage Vo.
Each voltage VonR / VoffR having a voltage value relatively lower than nB / VoffB is applied to the address electrode AjR. Note that FIG. 10 illustrates a fluctuation range (that is, a voltage difference (Von−Voff)) RNG1 of the voltage Von / Voff in the driving method according to the base technology for comparison.

As described above, in the driving method according to the fifth embodiment, in the address period AD1, the voltages VonR / VoffR and VonG / Voff having the voltage values set for the respective address electrodes AjR, AjG, and AjB for each emission color.
G, VonB / VoffB are applied. Moreover, these voltages VonR / VoffR, VonG / VoffG,
VonB / VoffB is the phosphor 108R of each emission color,
It is set based on the difference in the characteristics regarding the discharge for each of 108G and 108B (see FIG. 19). Therefore, the conventional PDP
It is possible to cancel the order of the occurrence of the address discharge that differs for each light emission color, which is included in 151. Therefore, according to the present driving method, the voltages Von, Voff, Vy
The adjustment width (margin) of each voltage value of
It can be wider than P151. As a result, in the PDP 51a driven by the appropriately set voltages Von, Voff, (−Vy), the erroneous write discharge is caused by the conventional PDP 51a.
It is reduced or eliminated compared to DP151. by this,
High-quality image display in which non-lighting and erroneous lighting during the maintenance period are reduced or eliminated can be obtained.

Further, by increasing the voltage adjustment range, the switching voltage range (VonR-
VoffR), (VonG-VoffG), (VonB
-VoffB) and the same voltage range (Von-V
off). For this reason, the load on the address electrode drive IC can be reduced. That is, the power consumption of the AC plasma display device including the AC PDP driven by the driving method according to the fifth embodiment can be reduced.

The voltages VonR / VoffR, Vo
When an address driver or an address electrode driving IC capable of variably adjusting nG / VoffG and VonB / VoffB independently is used, individual differences between a plurality of PDPs having different finished states of light emitting cells can be reduced or eliminated.

(Application Example 1 of Fifth Embodiment) In the fifth embodiment, the driving method is the same as that of the conventional PD in which the materials and dimensions of the constituent elements except for the phosphor material are the same between the respective emission colors.
The case of application to P151 has been described. The driving method according to the fifth embodiment is also effective for, for example, an AC-type PDP having each structure of the first to fourth embodiments.

Further, in the driving method according to the fifth embodiment, by controlling the distance between adjacent barrier ribs, the area where the phosphor for emitting blue light is disposed is enlarged as compared with the conventional AC PDP 151. In addition, an AC-type PDP having a structure in which the area where the red and green light emitting phosphors are arranged is reduced by that amount (proposed in Japanese Patent Application No. 10-40576 or Japanese Patent Application No. 11-5342). Applicable. According to such an AC type PDP, the emission intensity of blue light emission is relatively enhanced with respect to red and green light emission. In the AC type PDP, a discharge space for blue light emission is considerably larger than that for other light emission colors. For this reason, the discharge start voltage of the address opposite discharge in the address period may greatly differ between the blue light emitting cell and the red and green light emitting cells. In other words, a case may occur in which the generation probabilities of the address discharge differ between the respective emission colors.

The driving method according to the fifth embodiment is applied to such an AC type PDP so that at least the voltage VonB
By independently controlling the voltages VonR / VoffR and the voltages VonG / VoffG with only / VoffB alone, a sufficient voltage adjustment width (margin) can be given to each of the voltages Von, Voff, and Vy. As a result, it is possible to suppress or eliminate erroneous address discharge by averaging the generation probability of the address discharge between the emission colors.

(Embodiment 6) In Embodiment 6, for example, by applying to a conventional AC type PDP 151,
We propose a new driving method that can solve the above problems.
Needless to say, such a driving method is applied to the AC type PDPs 51a, 51
1b, 51c, and 51d may be used. In particular, the present driving method is characterized by a driving method in a sustain period corresponding to the sustain period S in the driving method according to the base technology,
A description will be given focusing on this point. Each driving method in the erasing period and the addressing period includes the erasing periods RA,
Each driving method in the RB and the address period AD is applicable.

FIG. 11 is a timing chart of the voltage applied to the address electrodes during the sustain period S1 in the driving method according to the sixth embodiment. (A-1) in FIG.
Each of (a-2) and (a-3) is a PDP 151
5 is a timing chart of voltages applied to the address electrodes AjR, AjG, and AjB disposed below the respective phosphor layers for red light emission, green light emission, and blue light emission in FIG. At this time, as for the timing chart of the voltage applied to the sustain electrode X and the like in the sustain period S1, each of (b) to (e) in FIG. 2 or FIG. 3 can be applied.

FIG. 11 shows, for comparison, a fluctuation range (that is, voltage Va) RNG2 of the voltage applied to the address electrode in the sustain period S of the driving method according to the base technology.

Maintaining period S of driving method according to Embodiment 6
1, the voltage Va (see FIG. 2 or FIG. 3) is set for each emission color, that is, for the address electrode AjR and the address electrode Aj.
G, different voltages VaR, V for each address electrode AjB
aG and VaB (the respective voltage values are also denoted by the same reference numerals) are applied (hereinafter, these are collectively referred to as voltage Va). Specifically, (a) the voltage value VaB is set such that the discharge intensity per sustain discharge in the blue light emitting cell is maximized, similarly to the voltage Va in the driving method according to the base technology ( That is, VaB = Va). And (b) adjusting the voltage values VaR and VaG so that the discharge intensity per sustain discharge in each of the red and green light emitting cells is relatively lower than that in the blue light emitting cell. Set to. At this time, when all the light emitting cells emit light, P
The voltage values VaR and VaG are set so that the chromaticity of white display as the entire DP becomes an optimum value.

In the conventional PDP 151, since the light emission intensity of the green light emitting cell is particularly high, in consideration of such a point, each of the voltage values VaR, VaG, and VaB becomes (Va =) VaB>VaR> VaG or (Va). =) VaB <VaR <VaG (6)

That is, in the driving method according to the sixth embodiment,
In the sustain period S1, each address electrode AjR, AjG,
Phosphors 108R, 108G, 1 of each emission color for each AjB
08B (see FIG. 19), the voltages VaR, VaG,
VaB is applied.

According to the above voltage setting conditions (a) and (b), each phosphor 108R, 108 per unit discharge intensity
The distortion of the balance between the emission intensities of G and 108B can be canceled and improved. Therefore, according to the driving method according to the sixth embodiment, unlike the conventional PDP 151,
Without making significant gain adjustments for each emission color (ie,
While ensuring the maximum number of gradations), the optimum white chromaticity is realized, and high-quality image display is possible.

Furthermore, when an address driver or an address electrode driving IC capable of variably adjusting each of the voltages VaR, VaG, and VaB is used, individual differences between a plurality of PDPs having different light emitting cell finishes can be reduced.
Can be removed. At this time, in some cases, the gain adjustment for each emission color can be completely eliminated.

As a display device or a driving method for displaying an image by supplying a different driving voltage for each emission color, for example, Japanese Patent Application Laid-Open No. 63-210914 and Japanese Patent Application Laid-Open No. 5-109375 disclose a prior art. Technology (below,
Each is also referred to as "prior art" and "prior art." The prior art relates to a liquid crystal display panel, and the prior art relates to a fluorescent display panel and a driving method thereof. Both the prior arts and the prior art aim at controlling a light emission intensity of each light emitting cell for each light emission color to obtain a predetermined color balance. The above object can be achieved by setting the “applied voltage or pulse waveform based on the image signal or image data in the ON state” input when selecting a cell to emit light to a different voltage or waveform for each emission color. And

Although the object itself is considered to be common to the driving method according to the sixth embodiment, the structure and driving method of the AC type PDP and the respective structures and driving methods of the liquid crystal display panel and the fluorescent display panel are fundamental. Therefore, there are significant differences (a) to (c) described below in detail between the two.
Exists.

(A) As described above, in the driving method of the AC type PDP, (i) in the address period, selective write discharge is performed on predetermined light emitting cells for image data in the ON state (wall). (Ii) the same voltage pulse is applied between all the electrode pairs or between the display electrode pairs in the sustain period, thereby maintaining the light emitting cells having the wall charges for the display light emission. Generates discharge. At this time, the emission intensity of the display emission in the AC type PDP is determined by the sustain discharge (weighting for each subfield) in the sustain period. Therefore, even if the above-described voltage Von based on the ON-state image data is adjusted for each emission color in the address period, the emission intensity of the display emission due to the sustain discharge in the sustain period is not controlled. That is, unlike a liquid crystal panel display or a fluorescent display panel, simply changing the applied voltage based on image data for each luminescent color does not improve the balance of the luminescent intensity of each luminescent color.

(B) In general, in an AC-type PDP, a phosphor arranged in a band along the address electrode Am and a band-shaped electrode to which a voltage for sustain discharge for defining emission intensity is applied. Xn and Yn are arranged in directions that intersect (three-dimensionally) with each other (for example, see FIG. 19). In addition, in the conventional AC type PDP (see FIG. 19), all the discharge cells have the same material (the phosphor material is different for each emission color) and the shape and size, so that they are arranged along the electrode pairs Xn and Yn. In all the light emitting cells, the sustain discharge is performed under the same condition with the same voltage applied between the pair of electrodes Xn and Yn. That is, in the structure of the AC type PDP, only the electrode pair Xn, Y
Only by controlling the voltage applied between n and n
The light emission intensity of the light emitting cells (plurality) belonging to n and Yn cannot be adjusted for each light emission color. Therefore, Embodiment 6
In AC, the discharge start voltage of the surface discharge (sustain discharge) between the electrodes Xn and Yn and the discharge efficiency such as the discharge efficiency of the discharge cell itself are controlled for each luminescent color, so that the luminescence intensity of each luminescent color can be controlled. A type PDP and a driving method thereof are provided.

On the other hand, in the liquid crystal display panel according to the prior art, the electrode pair Xn,
Only by adjusting the applied voltage between the column electrode and the row electrode corresponding to Yn for each emission color, the alignment state of the liquid crystal molecules arranged between the two electrodes is adjusted. Does not control the alignment performance of the liquid crystal molecules themselves with respect to the applied voltage for each emission color.

Further, according to the fluorescent display panel according to the prior art, by adjusting the voltage applied to the anode of the fluorescent display panel for each emission color, the heat corresponding to the electrode pair Xn, Yn of the AC type PDP can be obtained. The applied voltage between the cathode and the anode is adjusted for each emission color. That is, by controlling the state (speed and the like) of the thermoelectrons emitted from the hot cathode, the emission intensity of each emission color is adjusted. On the other hand, in the driving method according to the sixth embodiment, the discharge starting voltage necessary for forming a discharge (which can be regarded as being equivalent to the thermoelectrons), which is a characteristic of the discharge cell itself, is adjusted for each emission color. I do.

Further, in the prior art, a pulse-like voltage is applied to a green light-emitting cell having a relatively high light emission intensity, so that the lighting time ratio with respect to other light-emitting colors to which a DC voltage is applied is reduced. A driving method for adjusting the balance of light emission intensity has been proposed. However, such a driving method uses the AC-type PD described in the above-mentioned problem.
This corresponds to a driving method in which the ranking of subfields in P is changed for each emission color. That is, the driving method proposed in the prior art is completely different from the driving method according to the sixth embodiment.

(C) Next, the power consumption due to the switching operation for supplying / stopping the voltage to a predetermined electrode of each electrode driving IC will be considered. Generally, in a liquid crystal display panel, since the potential difference between each voltage in the ON state / OFF state based on the image data is small, the power consumption is very small. Further, in the fluorescent display panel, since the switching frequency is low, the power consumption is very small. Therefore, it can be said that in both of these panels, it is not necessary to adjust the applied voltage based on the image data in the “OFF state” for each emission color.

On the other hand, since the AC-type PDP utilizes a discharge phenomenon, various voltages applied to the AC-type PDP are higher than those of the liquid crystal display panel and the fluorescent display panel. For this reason, the reduction in power consumption accompanying the switching operation of the drive IC during the address period greatly contributes to the reduction in power consumption of the entire AC PDP. According to the driving method according to the fifth embodiment, in the address period, the voltage Von based on the ON-state image data is adjusted for each emission color, and the voltage Voff based on the OFF-state image data is also adjusted for each emission color. By performing the control, power saving during the switching operation of the driving IC can be realized. As described above, unlike the liquid crystal display panel and the fluorescent display panel, in the AC type PDP, the driving method according to the above-described fifth embodiment in which the applied voltage Von / Voff based on image data is controlled (for each emission color). In addition, it is possible to obtain a special effect of power saving of the driving IC, that is, power saving of the AC PDP.

(Embodiment 7) In Embodiments 7 to 9 described below, an AC type plasma display device having a driving device suitable for the driving methods of Embodiments 5 and 6 will be described. Prior to the description, a driving device of the conventional plasma display device 100 (having the conventional AC PDP 151 of FIG. 19) will be described first.

In order to avoid complication of the drawing, FIG.

When this AC type plasma display device is driven by the driving method according to the sixth embodiment, the voltage V is applied during the sustain period S1 (see FIG. 11).
Each of HR, VHG, VHB is set to each of the voltages VaR, VaG, VaB (see FIG. 11) in the driving method according to the sixth embodiment, and the voltages VLR, VLG, VL are set.
Each of B is set to voltage (value) 0.

By setting the voltage as described above, the present AC plasma display device can surely exhibit the effects resulting from the driving method according to the fifth or sixth embodiment.

In the conventional plasma display device, as described above, the address electrode drive IC 13P1,
13P2 and 13P3 process image data of all luminescent colors. For this reason, the input image data DATA composed of the image data DR, DG, and DB which are originally divided into colors are converted into the red image data DR1, the green image data DG1, the blue image data DB1, and the red image data DR.
2, green image data DG2, blue image data DB2,.
It is necessary to perform signal processing for conversion into the data cycle (see FIG. 12). On the other hand, Embodiment 7
AC type plasma display device according to (see FIG. 14)
Then, a dedicated address electrode driving IC 13 for each emission color

Can be directly input to the address electrode drive ICs 13R, 13G, and 13B without being converted into the above-described data cycle.
Therefore, according to the AC type plasma display device according to the seventh embodiment, the signal conversion processing and the processing circuit required for the conventional plasma display device are unnecessary.

In driving the conventional plasma display device shown in FIG. 12, during the sustain period, the voltage VH is changed to the voltage VaB in the driving method of the sixth embodiment.
When the voltage VL is treated as a voltage common to the voltage VaR and the voltage VaG in the same driving method (that is, VaR = VaG), light emission of blue light emission in the sustain period is performed by adjusting the voltages VH and VL. The intensity can be increased relative to both red and green emission intensities. That is, the driving method according to the sixth embodiment can be simply performed (although the driving is not completely independent for each emission color) by the conventional plasma display device. Therefore, it is possible to obtain a certain degree of white display close to the optimum white chromaticity. In particular, in such a case, there is an advantage that the number of power supply circuits can be reduced as compared with the plasma display device of FIG.

(Embodiment 8) In the AC type plasma display device according to Embodiment 7, the output terminals of the address electrode drive ICs 13R, 13G and 13B and the input terminals TA _{1 to} TA _3k of the address electrode Am are connected. A three-dimensional wiring structure is formed in a path between them. For this reason, such a wiring structure may be more complicated than the conventional plasma display device of FIG.

The AC type P according to the third embodiment described above is now described.
In the DP 51c (see FIG. 8), the address electrodes 6Rc, 6
Gc and 6Bc are different surfaces or formation surfaces 9 respectively.
It is formed on S, 10SMc and 10SLc. That is, the address electrodes 6Rc, 6Gc, 6Bc for the respective emission colors.
Are three-dimensionally arranged on the front surface 9S side of the rear glass substrate 9. Therefore, in the eighth embodiment, the AC type PDP 51
An AC-type plasma display device that can solve the problem of the above-described complicated wiring structure by using the AC-type PDP 51e having the lead portion area AR2 using the arrangement structure of the address electrodes c will be described. In the following description, the same reference numerals are given to the same components as the components according to the seventh embodiment, and the description will be referred to. Also, A
AC type PDP is the basic PDP of C type PDP 51e.
AC PDP According to Embodiment 4 Instead of DP51c

In order to facilitate understanding of the following description, FIG. 15 shows an address electrode and a terminal T of the PDP 51e corresponding to each address electrode.

The structure of the DP 51e is the same as that of the AC type PDP according to the third embodiment.
Since the structure is basically based on the structure of 51c, the following description will be made with reference to FIG.

[0174] As shown in FIG. 8 or FIG. 15, along the address electrodes _{A 1 R, A 1 G,} A 1 B~A k R, A k G, A k B ( second direction D2 is in the display area AR1 Are arranged in parallel in the display area AR1 via the lower or middle overglaze layers 10Lc and 10Mc.

In Embodiment 8, in particular,
Subsequent to the display area AR1, three overglaze layers 10Lc, 10Mc, and 10Uc are also formed to extend in an extended area AR2 provided on the end side of the PDP 51c (see the area AR4 in FIG. 15). Therefore, each of the address electrodes A ₁ R, A ₁ G, A ₁ B to A _k R, A _k G, A _k
B is also electrically insulated also in the lead portion area AR2. The PDP 51e according to the eighth embodiment
Then, the address electrodes A ₁ R, A ₁ G, A ₁ B to A _k R, A _k

On Lc, it is formed as a shape toward the predetermined terminal TA ₁ ~TA _3k. That is, as shown in FIG.
In the display area AR1, the address electrodes A ₁ R, A ₁ G, A ₁ B to A _k R, A _k arranged in the second direction D2 by repeating the order of red, green, and blue. G, A _k
B are connected to the lead portion area AR
2 are rearranged without crossing each other in the same plane. At this time, in the area on the side of the terminal area AR3 in the lead area AR2, the arrangement order of the respective wirings in the second direction D2 is the address electrode driving IC 13
The output terminals of R, 13G, and 13B are rearranged so as to match the arrangement order. Thus, the address electrode driving IC13R, 13G, each of the address electrodes A ₁ R and the output terminals of the _{13B, A 1 G, A 1} B~A k R, A k G, and the A _k B, a single-layer structure It is connected via the FPC15 and the terminals TA ₁ ~TA _3k.

Therefore, according to the PDP 51e having the above-described wiring structure in the lead-out area AR2, the terminals TA _{1 to} TA _{3k in the} terminal area AR3 and the output terminals of the address electrode drive ICs 13R, 13G, and 13B are connected. Can be effectively avoided.

At this time, when the AC plasma display device according to the eighth embodiment, that is, the AC PDP 51e is driven by the driving method according to the fifth embodiment,
In the address period AD1, the voltages VRH, VGH, V
BH is set to each of the voltages VonR, VonG, and VonB in the driving method according to the fifth embodiment, and each of the voltages VRL, VGL, and VBL is set to each of the voltages VoffR, VoffG, and VoffB in the driving method. . As a result, in addition to the above simplification of the wiring structure, A
The above-described effects resulting from the structure of the C-type PDP 51e (therefore, the structure of the PDP 51c) and the driving method according to the fifth embodiment can be obtained. In the sustain period S1, the voltages VRH, VGH, and VBH are changed to the voltages VaR, VaG, and VG in the driving method according to the sixth embodiment.
VaB and the voltages VRL, VGL, V
By setting each of the BLs to a voltage (value) of 0, the present AC type plasma display device is used in the sixth embodiment.
The same effect can be obtained when the driving method according to the above is applied.

(Embodiment 9) PDP applied to AC plasma display device according to Embodiment 8 described above
At 51e, for example, the address electrode A _k R in FIG.
, The address electrode A _k R and the address electrode A _k R
When the terminal TA _k to be connected to is separated from the terminal TA _k, it is necessary to give a steep angle to the shape of the wiring connecting the two terminals A _k R and TA _{k in} the lead portion area AR2.

Further, when the wirings are integrated near the center of the lead portion area AR2 in the second direction D2 as in the case of the address electrodes A ₁ G to A _k G, that is, the address electrodes are almost at the location where the concentration occurs. As compared with the case where the electrodes are arranged symmetrically, the address electrodes A ₁ R to
A _k R, as A ₁ B~A _k B, predetermined terminal TA ₁ to Ta _k to be connected, when having a large number of electrodes the distance to the TA _2k + 1 ~TA _3k is away, drawers In the partial region AR2, the number of wires per unit length locally increases. At this time, the wiring in the lead portion area AR2 must be formed very densely, that is, the wiring pattern must be miniaturized.

As described above, AC-type PDP 51 applied to the AC-type plasma display device according to the eighth embodiment.
e has a necessity to form a complicated and miniaturized wiring pattern in the lead portion area AR2.

On the other hand, in order to eliminate the complexity and miniaturization of the wiring pattern, it is conceivable to enlarge the lead portion area AR2 itself. At this time, without reducing the size of the display area AR1, the lead portion area AR2
In order to enlarge the size, the size of the rear glass substrate 9 may be increased. However, in such a case, there arises a problem that the size of the AC type PDP itself is increased by an amount corresponding to the enlargement.

Therefore, in the ninth embodiment, the AC type PD
Provided are an AC-type PDP and a plasma display device which can avoid the complexity and miniaturization of the wiring pattern in the above-mentioned lead portion area AR2 without increasing the size of P. Here, similarly to the conventional AC type PDP 151, an AC type PD in which all the address electrodes Am are formed in the same plane is used.
An AC plasma display device having P51f (to be described later) and to which the driving methods according to the fifth and sixth embodiments can be applied will be described. In the following description, as an example, in the address period or the sustain period, the address discharge or the sustain discharge in the green light emitting cells is less likely to occur than the address discharge or the sustain discharge in each of the red or blue light emitting cells. A description is given below. Note that both the red and blue light emitting cells have substantially the same ease of discharge.

One or pulled out upward side of the terminal area AR21 of P51f, are connected to each the 2k terminal TA ₁ to Ta _2k in the same terminal area AR21. Terminal TA ₁
To TA _2k are connected to one predetermined output terminal of two address electrode drive ICs 13RB via a single-layer FPC 15C1. Note that the arrangement order of the output terminals of the (two) address electrode driving ICs 13RB and the address electrodes A ₁ R to
The sequence order of A _k R, A ₁ B to A _k B is consistent. Therefore, the (plural) wirings between the address electrodes A ₁ R to A _k R, A ₁ B to A _k B and the output terminals of the address electrode driving IC 13RB do not cross each other. In addition,
The two address electrode drive ICs 13RB have the same structure. The two driving ICs 13RB correspond to a voltage VHRB generated and output by the power supply circuit 16RBH and corresponding to the voltage VH (see FIG. 12), and a voltage VL generated and output by the power supply circuit 16RBL and corresponding to the voltage VL (see FIG. 12). Is supplied. And both drive ICs 13
The RB outputs one of the voltages VHRB and VLRB based on the input image data DRB including the red image data DR1 to DRk and the blue image data DB1 to DBk.

On the other hand, as shown in FIG. 18, the address electrodes A ₁ G to A _k G are led out to the side of the terminal area AR22 provided on the other side or below the PDP 51f, and are arranged in the terminal area AR22. K terminals TA _{2k + 1 to} T
A _3k is connected to each. Terminal TA _{2k + 1 to} TA _3k
Are connected to a predetermined output terminal of the address electrode drive IC 13G via a single-layer FPC 15C2. At this time, (s) lines between the output terminals of the respective address electrodes A ₁ G~A _k G and the address electrode driving IC13G does not intersect with each other. The address electrode drive IC 13G is provided with the address electrode drive IC 13G.
It has a structure equivalent to C13RB. The driving IC 13G

As described above, the address electrodes A ₁ R, A ₁ B to
A _k R and A _k B are connected to the respective output terminals of the address electrode drive IC 13RB in the same arrangement order without changing the arrangement order in the display area AR1. The same applies to the arrangement order of the address electrodes A ₁ G to A _k G.
Therefore, according to the PDP 51f, the PDP according to Embodiment 8
As compared with the DP 51e (see FIG. 15), the wiring does not have a steep angle in the lead portion regions AR21 and AR22. In addition, in the PDP 51f, the number of address electrodes led out to the terminal area AR21 and AR22 is 2k and k, respectively.
Compared with the DP 51e and the conventional PDP 151 of FIG. 12, the wiring pattern in the lead portion area can be simplified. Further, address electrode driving ICs 13RB, 13G
Output terminals and address electrodes A ₁ R, A ₁ G, A ₁ B to A _k
Since there is no three-dimensional wiring structure between R, A _k G, and A _k B, it is simpler than the AC type plasma display device according to the seventh or eighth embodiment (see FIG. 14 or 15). It has a simplified wiring structure.

Thus, the PDP 51f and the PDP 51f
According to the AC type plasma display device shown in FIGS. 16 to 18 including 51f, it is possible to avoid the complexity and miniaturization of the wiring pattern in the lead portion region without increasing the size of the AC type PDP.

In the AC type plasma display device according to the ninth embodiment, the image data DRB _{1 to} DRB _2k (red image data D
R ₁ , blue image data DB ₁ ,..., Red image data D
R _k and the blue image data DB _k are converted), and
It is driven based on the green image data DG ₁ ~DG _k inputted to the address electrode driving IC13G.

At this time, in the address period AD1,
The above-described voltage VonR as the voltage VHRB / VLRB
/ VoffR or the voltage VonB / VoffB is set to a common (first) voltage VonRB / (second) voltage VoffRB (that is, VonR = VonB = V
onRB, VoffR = VoffB = VoffRB),
In addition, by setting (first) voltage VonG / (second) voltage VoffG having a voltage value higher than the voltages VonRB / VoffRB as the voltages VHG / VLG, respectively, the driving method according to the fifth embodiment can be performed by using (Simplified). Therefore, Embodiment 9
According to the AC-type plasma display device according to the present invention, almost the same effects as those of the AC-type plasma display device according to the fifth embodiment are exerted, and the AC-type plasma display device capable of realizing image display at a practically sufficient level is provided. Can be provided.

Further, according to the AC type plasma display device according to the ninth embodiment, in the sustain period S1, the above-described voltages VaB, VaR, VaG and the voltages (values) are respectively used as the voltages VHRB, VLRB, VHG and VLG. By setting 0), the driving method according to the sixth embodiment can be applied (simplified). In such a case, almost the same effect as that of the AC type plasma display device according to the sixth embodiment is exerted, and it is possible to provide an AC type plasma display device capable of realizing a practically sufficient level of image display.

(Embodiment 10) As described above, the conventional PDP 151 in which all the discharge cells have the same material and the same shape (except for the difference in the phosphor material) is provided along the longitudinal direction of the scanning line Ln. Therefore, the luminance distribution is such that the center of the screen is darker than the both ends (the above-mentioned problem). Embodiment 10
Now, an AC type PDP and an AC type PDP
A method of driving a PDP and an AC plasma display device to which the PDP is applied will be described.

As described in the second and fourth embodiments, in the AC type PDP, (a) by changing the width of the address electrode below each phosphor for each emission color, or (b) by changing the address. By changing the thickness of the overglaze layer or the thickness of the discharge space corresponding to the electrode for each luminescent color, it is possible to correct the luminous intensity balance between the luminescent colors of display luminescence during the sustain period. Furthermore, as described in the sixth embodiment, (in the case where the conventional PDP 151 is driven according to the prerequisite technology), (c) the voltage applied to the address electrode during the sustain period is reduced by the fluorescent material corresponding to the same electrode. By making a difference for each emission color, it is possible to correct the balance of the emission intensity between the emission colors of the display emission during the sustain period.

As described above, each of the means (a) to (c) can appropriately design or drive the structure of each discharge cell, which is the same in the conventional PDP 151, for each luminescent color, and This is for controlling the balance of the emission intensity of the emission color. By applying such a point of interest, the above-described luminance distribution can be corrected by controlling the light emission intensity of the (a plurality of) light emitting cells along the longitudinal direction of the scanning line Ln for each individual light emitting cell. That is, (A) the width of the address electrode Am is set to be wider from the central portion in the longitudinal direction of the scanning line Ln or the arrangement direction of the address electrode toward both ends. At this time, the voltage Va applied to the address electrode Am in the sustain period
(See FIG. 2 or FIG. 3) is adjusted so that the discharge intensity of the sustain discharge is lower than that of the conventional PDP 151.

(B) The thickness of the overglaze layer or the thickness of the discharge space corresponding to each address electrode Am increases from the center to the both ends in the longitudinal direction of the scanning line Ln or the arrangement direction of the address electrodes. Set smaller. The voltage Va is adjusted in the same manner as in the means (A). At this time, the thickness distribution of the discharge space described above may be formed by adjusting the height distribution of the barrier ribs along the longitudinal direction of the scanning line Ln.

(C) When the driving method according to the base technology is applied to the conventional PDP 151, the voltage value of the voltage Va is set as follows. That is, the voltage value of the voltage Va is set at the central portion in the longitudinal direction of the scanning line Ln or the arrangement direction of the address electrodes so that the discharge intensity of the sustain discharge is maximized, as in the driving method according to the base technology. On the other hand, the voltage Va is set to a larger or smaller voltage value toward the both ends in the direction from the center (that is, the voltage Va shifts from the center to the both ends). Increase the amount).

According to the above means (A) to (C), each has a maximum value at the center in the longitudinal direction of the scanning line Ln or the arrangement direction of the address electrodes, and has both ends from the center to both ends. It is possible to form a sustain discharge having a discharge intensity distribution in which the intensity decreases as approaching the portion. As a result, it is possible to suppress and eliminate the influence of the voltage drop in the lead caused by the bus electrodes of the electrodes Xn and Yn forming the scanning line Ln. Therefore, the AC-type PDP or the plasma display device including the above-described units (A) to (C) can realize a uniform luminance distribution over the entire screen of the PDP.

According to the above means (A) and (B), the luminance of the central portion in the longitudinal direction of the scanning line Ln is maintained equal to that of the conventional PDP 151. On the other hand, according to the means (C), it is also possible to increase the luminance at the central portion.

Further, the power consumption due to the sustain discharge is reduced for the entire display area. At this time, the illuminance of the display light emission emitted from the entire display area is equal to that of the conventional PDP 151.
Although the luminous efficiency is not actually improved since the brightness is lower than that of the conventional PDP 151, the brightness of the central portion is relatively improved with respect to the brightness of both ends of the display area. I feel that the whole is bright. For this reason, "compared to the conventional PDP 151,
Since the power consumption is reduced and the display area is brighter (feeling), the luminous efficiency has been greatly improved. " In other words, even when the brightness at the center portion is relatively increased by further reducing the brightness at the both end portions of the PDP using the means (A) to (C) described above. In addition, the power consumption can be significantly reduced without giving a connotation that the entire display area is significantly darkened.

Further, due to the discharge intensity distribution of the sustain discharge by each of the means (A) to (C), the above-described reduction in power consumption is particularly remarkable at the both ends of the PDP. Therefore, the calorific value of the PDP at both ends is lower than that of the conventional PDP 151. Therefore, at least the portions near the both ends are generated at the time of the PDP display operation.
The in-plane temperature gradient of front glass substrate 5 or rear glass substrate 9 is alleviated as compared with conventional PDP 151. as a result,
It is possible to prevent the hermeticity of the PDP from lowering due to the thermal stress caused by the temperature gradient.

It is needless to say that the above-described first to tenth embodiments are combined with each other and implemented, so that the above-described respective effects achieved when each is implemented separately can be further ensured. No.

In each of the first and second embodiments and the fifth to tenth embodiments, there is provided an AC type PDP having no overglaze layer and having a structure in which a fluorescent material directly covers an address electrode. Note that is also applicable.

[0202]

(1) According to the first aspect of the present invention, the underlying elements have a predetermined structure which is not all the same in each of the divisions and is set. For this reason, when such an AC plasma display panel substrate is applied to an AC plasma display panel, it is necessary that characteristics relating to discharge based on a predetermined structure for each section of the base element are given to all, instead of being the same. Can be. That is,
The discharge characteristics or discharge cells belonging to the same category (plural) can be grouped into one group to control the discharge characteristics. In such a case, when the structure is appropriately set for each section, the difference in the address discharge between the discharge colors of the discharge cells or the light-emitting cells of the conventional AC type plasma display panel, and the difference between the light-emitting colors in the display light emission. And the luminance distribution along the arrangement direction of the (plural) address electrodes in the display area can be suppressed or eliminated. That is, it is possible to provide an AC type plasma display panel capable of realizing higher quality image display than the conventional AC type plasma display panel.

(2) According to the second aspect of the present invention, the width of each address electrode is set based on the arrangement position of each section of the base element in the substrate for an AC plasma display panel. Therefore, when the substrate for an AC plasma display panel is applied to an AC plasma display panel and the same voltage is applied to each address electrode,
The distribution of the electric field in the discharge space of the discharge cells can be controlled for each (plural) discharge cells belonging to each section by the electric field resulting from the voltage. At this time, the wider the width of the address electrode, the greater the influence on the electric field formation in the discharge space. Therefore, by controlling the electric field in the discharge space,
It is possible to provide an AC plasma display panel capable of suppressing and removing a luminance distribution along a direction in which (a plurality of) address electrodes are arranged in a display area of a conventional AC plasma display panel.

Further, a phosphor that emits a predetermined emission color for each section is further provided, and based on the arrangement position of the phosphor for each emission color on the substrate for an AC type plasma display panel (accordingly, each of the base elements When the width of each address electrode is set based on the arrangement position of the section), the conventional AC plasma display panel is applied to the AC plasma display panel by applying the AC plasma display panel substrate to the conventional AC plasma display panel. Provided is an AC-type plasma display panel capable of suppressing and removing a difference in address discharge between emission colors of discharge cells or emission cells and an imbalance in emission intensity between emission colors in display emission. it can.

(3) According to the third aspect of the present invention, the width of each address electrode ranges from the central portion in the arrangement direction of the address electrodes (which can also be regarded as the arrangement direction of each section of the base element) to both ends thereof. The size is set to be larger as going to the side. Therefore, the AC-type plasma display panel is composed of the AC-type plasma display panel substrate and another AC-type plasma display panel substrate having an electrode pair arranged in a direction intersecting the address electrode and forming a scanning line. In the case where the same voltage is applied to each of the address electrodes and a predetermined voltage is supplied from the opposite ends to the two electrodes forming the electrode pair, the voltage is applied to the address electrodes. The magnitude of the electric field of the sustain discharge between the pair of electrodes, that is, the intensity of the discharge, can be made smaller from the central part in the arrangement direction toward both ends by the electric field caused by the applied voltage. Therefore, it is possible to provide an AC plasma display panel capable of suppressing and removing the luminance distribution along the above-mentioned direction in the display area of the conventional AC plasma display panel.

(4) According to the fourth aspect of the invention, the thickness of the dielectric is set based on the arrangement position of the division of the base element in the substrate for an AC type plasma display panel.
For this reason, when the AC type plasma display panel substrate is applied to the AC type plasma display panel and the same voltage is applied to each address electrode, the discharge space corresponding to the thicker dielectric is caused by the same voltage. The influence of the generated electric field on the electric field formation in the discharge space is smaller. That is, it is possible to control the electric field formed in the discharge space for each discharge space by the thickness of the dielectric material set for each section.

Further, a phosphor that emits a predetermined emission color for each section is further provided, and based on the arrangement position of the phosphor for each emission color on the substrate for an AC plasma display panel (accordingly, each of the base elements In the case where the thickness of the dielectric is set based on the arrangement position of the sections, the conventional AC plasma display panel is applied to the AC plasma display panel so that the conventional AC plasma display panel can be used. It is possible to suppress or eliminate the difference in the address discharge between the light emitting colors of the respective discharge cells or the light emitting cells and the imbalance of the light emission intensity between the light emitting colors in the display light emission.

Accordingly, the same effect as the above (2) can be obtained by the AC type plasma display panel substrate according to the fourth aspect of the present invention.

(5) According to the fifth aspect of the present invention, the thickness of each dielectric is set to be larger as it goes from the center in the arrangement direction of the address electrodes toward both ends thereof. For this reason, the AC plasma display panel is composed of the AC plasma display panel substrate and another AC plasma display panel substrate having an electrode pair arranged in a direction intersecting the address electrodes and forming a scanning line. A panel is formed, and the same voltage is applied to each of the address electrodes.
When each predetermined voltage is supplied to the two electrodes from opposite ends, the magnitude of the electric field of the sustain discharge between the pair of electrodes, i.e., the electric field caused by the voltage applied to the address electrode, that is, In addition, the discharge intensity can be further reduced from the central portion in the arrangement direction toward both ends.

Therefore, the same effect as the above (3) can be obtained by the AC type plasma display panel substrate according to the fifth aspect of the present invention.

(6) According to the sixth aspect of the invention, the width of the address electrode is set based on the emission color of the phosphor belonging to the division of the base element. For this reason, the AC plasma display panel is composed of the AC plasma display panel substrate and another AC plasma display panel substrate having an electrode pair arranged in a direction intersecting the address electrodes and forming a scanning line. When a panel is configured and a predetermined voltage is applied to each address electrode, each discharge intensity of a counter discharge between the address electrode and the above-mentioned electrode pair (a scanning electrode thereof) and a surface discharge between the above-mentioned electrode pair is determined. It can be different for each emission color. At this time, the wider the width of the address electrode, the greater the influence on the electric field formation in the discharge space. Therefore, according to the substrate for an AC type plasma display panel of the invention according to claim 6, the difference in the address discharge between the emission colors of the discharge cells or the emission cells described above and the emission intensity between the emission colors in the display emission are also provided. The imbalance of balance can be suppressed or eliminated.

(7) According to the invention of claim 7, the thickness of each dielectric is set based on the emission color of the phosphor belonging to each section of the underlying element. Therefore, the AC-type plasma display panel is composed of the AC-type plasma display panel substrate and another AC-type plasma display panel substrate having an electrode pair arranged in a direction intersecting the address electrode and forming a scanning line. When a predetermined voltage is applied to each address electrode, the respective discharge intensities of the counter discharge between the address electrode and the above-mentioned electrode pair (the scanning electrode thereof) and the surface discharge between the above-mentioned electrode pair are set to respective values. It can be different for each emission color.

Therefore, the same effect as the above (6) can be obtained by the AC type plasma display panel substrate according to the seventh aspect of the present invention.

(8) According to the eighth aspect of the present invention, the terminals are arranged separately at both ends of the substrate in the longitudinal direction of the address electrodes. At this time, the plurality of address electrodes are classified into two groups by using the emission color of the phosphor as a unit, and are connected to terminals arranged at either end of both ends. For this reason, in an AC plasma display device having an AC plasma display panel to which the AC plasma display panel substrate is applied, a predetermined power supply circuit is provided via each terminal from a common power supply circuit for each group of address electrodes. When a voltage is supplied, the effect (6) or (7) can be obtained at a practically sufficient level. At this time, there is an advantage that the number of power supply circuits can be reduced by the amount of the above-mentioned commonization as compared with the case where different power supply circuits are provided for each division of the base element.

(9) According to the ninth aspect of the present invention, any of the above-mentioned effects (1) to (8) is exhibited, and the image display can be performed as compared with the conventional AC type plasma display panel. A significantly improved AC type plasma display panel can be realized.

(10) According to the tenth aspect,
The thickness of each discharge space is not the same for every discharge space along the longitudinal direction of the address electrode. For this reason,
When the same voltage is applied to each address electrode, the smaller the thickness of the discharge space, the greater the effect of the electric field resulting from the voltage on the formation of the electric field in the discharge space. That is, the electric field distribution or electric field intensity formed in the discharge space can be controlled by the thickness of the dielectric. Therefore, according to the AC-type plasma display panel of the tenth aspect, when the thickness of the discharge space is appropriately set, the same effect as the above (1) can be obtained.

(11) According to the eleventh aspect,
The thickness of each discharge space is set based on the arrangement position of the address electrode corresponding to the discharge space in the first substrate. For this reason, it is possible to control the discharge distribution or discharge intensity formed in the discharge space corresponding to the address electrode for each of the above-mentioned arrangement positions of each address electrode.

Further, when the thickness of each discharge space is set based on the arrangement position of the phosphor for each emission color in the first substrate (accordingly, based on the arrangement position of the address electrode). Can suppress or eliminate differences in the address discharge between the emission colors of the discharge cells or the emission cells described above and the imbalance in the emission intensity between the emission colors in the display emission.

Therefore, the same effect as the above (2) can be obtained by the AC type plasma display panel according to the eleventh aspect.

(12) According to the twelfth aspect,
The thickness of each discharge space is set to be smaller as it goes from the center in the arrangement direction of the address electrodes toward both ends thereof. For this reason, when applying the same voltage to each of the address electrodes and supplying predetermined voltages to the scanning electrodes and the sustain electrodes forming the electrode pairs from opposite ends, respectively, the address electrodes are applied to the address electrodes. By the electric field resulting from the applied voltage, the magnitude of the electric field of the sustain discharge between the electrode pairs, that is, the discharge intensity, can be made smaller from the central portion in the arrangement direction toward both ends.

Therefore, according to the substrate for an AC type plasma display panel of the twelfth aspect, the above (3) can be achieved.
The same effect as described above can be obtained.

(13) According to the thirteenth aspect,
The thickness of each discharge space is set based on the emission color of the phosphor corresponding to the discharge space. For this reason, when a predetermined voltage is applied to each address electrode, the discharge intensity of the counter discharge between the address electrode and the scan electrode and the discharge intensity of the surface discharge between the electrode pair can be different for each emission color. . Therefore, according to the AC-type plasma display panel of the invention according to the thirteenth aspect, the difference in the address discharge between the emission colors of the discharge cells or the emission cells described above and the balance of the emission intensity between the emission colors in the display emission are also achieved. Imbalance can be suppressed and eliminated.

(14) According to the fourteenth aspect,
By exhibiting any of the effects (9) to (13) described above, it is possible to provide an AC plasma display device in which image display is significantly improved as compared with the conventional AC plasma display device.

(15) According to the fifteenth aspect,
A predetermined voltage that is not the same for all the address electrodes is applied. Therefore, it is possible to control the discharge intensity of the discharge generated therein for each (plural) discharge cell or discharge space to which each address electrode belongs. Therefore, when the voltage applied to the address electrodes is appropriately set for each address electrode, the difference in the address discharge between the emission colors of the discharge cells or the light-emitting cells of the conventional AC-type plasma display panel, and the display emission. It is possible to suppress or eliminate the imbalance of the emission intensity balance between the respective emission colors and the luminance distribution along the arrangement direction of the (plural) address electrodes in the display area. That is, it is possible to realize image display of higher quality than image display by the conventional driving method.

(16) According to the sixteenth aspect,
Each voltage value of the first voltage and the second voltage is set based on the emission color of the phosphor corresponding to the address electrode. For this reason, even if the characteristics relating to the discharge caused by the phosphor material itself are different for each emission color, the control of the electric field in the discharge space by the first voltage and the second voltage makes it possible to control the respective characteristics of the discharge related to the fluorescent light. The difference between body materials can be corrected. Therefore, by making uniform the difficulty of the address discharge in the address period, which is different for each light emission color, it is possible to execute the reliable address discharge. As a result, higher-quality image display in which non-lighting and erroneous lighting and the like are suppressed or eliminated as compared with the image display by the conventional driving method can be obtained in the sustain discharge period for display light emission.

(17) According to the seventeenth aspect,
The first voltage and the second voltage are based on the correlation between the emission color and the magnitude of the discharge start voltage of the counter discharge between the address electrode and the scan electrode for the emission color, and the discharge start between the emission colors is performed. Appropriately set to equalize the voltage. For this reason, the effect (16) can be reliably obtained.

(18) According to the eighteenth aspect,
A predetermined voltage set for each address electrode is applied to the address electrodes during the sustain period. Therefore, the discharge intensity of the sustain discharge formed between the scan electrode and the sustain electrode can be controlled by the electric field of the predetermined voltage. For example, when the predetermined voltage is appropriately set based on each emission color, it is possible to reduce or eliminate the color balance deviation of the entire AC type plasma display panel. Further, according to the conventional driving method, when applying a larger voltage to the address electrodes corresponding to relatively bright spots in the longitudinal direction of the electrode pairs or the arrangement direction of the address electrodes, The overall brightness can be made uniform. As a result, it is possible to obtain a higher quality image display than the image display by the conventional driving method while securing the maximum number of gradations.

(19) According to the nineteenth aspect,
The predetermined voltage applied to each address electrode during the sustain period is set based on the light emission intensity per unit discharge intensity in the discharge cell for each light emission color. For this reason, when setting the discharge intensity of the sustain discharge by such a predetermined voltage so as to equalize the light emission intensity of the discharge cells or discharge spaces for each emission color, the balance of the chromaticity in the entire AC type plasma display panel is adjusted. Displacement can be reliably reduced and eliminated. As a result, it is possible to obtain a higher quality image display than the image display by the conventional driving method while securing the maximum number of gradations.

(20) According to the twentieth aspect,
The predetermined voltage is set so that the emission color of the entire AC plasma display panel when all the discharge cells emit light has a predetermined color coordinate value. For this reason, the deviation of the chromaticity balance of the entire AC type plasma display panel can be reliably eliminated. Therefore, it is possible to obtain a particularly high-quality image display as compared with the image display by the conventional driving method.

(21) According to the twenty-first aspect,
The plurality of luminescent colors are classified into a plurality of groups by the luminescent color unit, and the AC type plasma display panel is driven for each of the groups. For this reason, any of the effects (15) to (20) can be obtained at a practically sufficient level, and a predetermined voltage is supplied to the address electrodes belonging to each group from the power supply circuit shared for each group. In some cases, there is an advantage that the number of power supply circuits can be reduced by the amount of the above commonality as compared with the case where different power supply circuits are provided for each emission color.

(22) According to the twenty-second aspect,
The predetermined voltage applied to the address electrodes during the sustain period is set based on the location of the address electrodes in the AC type plasma display panel. For this reason, according to the conventional driving method, when applying a predetermined voltage to the address electrodes corresponding to relatively bright spots in the longitudinal direction of the electrode pairs or the arrangement direction of the address electrodes, an AC plasma display is used. The brightness of the entire panel can be made uniform. Further, for example, when the predetermined voltage is appropriately set based on the arrangement position of the phosphor of each emission color (accordingly, based on the arrangement position of the address electrode), the color balance of the entire AC type plasma display panel is adjusted. Displacement can be reduced or eliminated. As a result, it is possible to obtain a higher quality image display than the image display by the conventional driving method while securing the maximum number of gradations.

(23) According to the invention according to claim 23,
A larger or smaller voltage is applied to each address electrode from the center in the arrangement direction of the plurality of address electrodes toward both ends thereof. At this time, when each predetermined voltage is supplied from the opposite ends to the scanning electrode and the sustaining electrode forming an electrode pair, an electric field caused by the voltage applied to the address electrode causes a voltage between the electrode pair. , That is, the intensity of the electric field of the sustain discharge, that is, the discharge intensity, can be made smaller from the central portion in the arrangement direction to both end portions thereof. Therefore, the brightness distribution along the above-mentioned direction in the display area of the conventional AC type plasma display panel is suppressed or eliminated, and it is possible to obtain a higher quality image display than the image display by the conventional driving method.

(24) According to the invention according to claim 24,
