Description

  The present invention relates to a gas discharge light-emitting panel, which is an image display device using light emission of a phosphor by ultraviolet rays generated by gas discharge.

  In recent years, development of a gas discharge light emitting panel, typically a plasma display panel (PDP), has been promoted as an image display device capable of realizing high definition and high brightness. Since PDPs can be easily enlarged in screen size, they are expected to become more popular in the future.

In PDP, so-called three primary colors (red, green, blue) are additively mixed to display a full-color image. In order to perform such full-color display, the PDP usually discharges a phosphor layer (a red phosphor layer, a green phosphor layer, or a blue phosphor layer) containing phosphors that emit red, green, or blue colors. It is provided for each cell. The phosphor is excited by the irradiation of ultraviolet rays (vacuum ultraviolet rays) generated by gas discharge in the discharge space, and emits light of each color. The discharge cells are arranged in a predetermined pattern, and an image is displayed by controlling the timing of gas discharge for each discharge cell (that is, the timing of ultraviolet irradiation to the phosphor). Such a PDP structure is disclosed in Non-Patent Document 1, for example.

  However, in the PDP, it is known that the luminance decreases with time according to the panel driving time in each discharge cell. The decrease in luminance is considered to occur because the emission intensity of the phosphor decreases due to the deterioration of the phosphor due to ion bombardment during discharge or irradiation with vacuum ultraviolet rays. Such a decrease in brightness is likely to occur when a certain pattern is displayed continuously like a still image, but the brightness differs between discharge cells with different lighting times, and a pattern different from the above-mentioned constant pattern is displayed. In this case, a phenomenon in which the previous pattern appears as an afterimage (generally called “burn-in phenomenon”) may occur.

  For these reasons, a gas discharge light-emitting panel is desired in which the display characteristics of the panel are prevented from deteriorating with a decrease in the emission intensity of the phosphor.

  The gas discharge light-emitting panel of the present invention is disposed on the main surface on the discharge space side of the back plate and the front plate and the back plate arranged to face each other through the discharge space, and is generated in the discharge space. A gas discharge light-emitting panel comprising a phosphor layer containing a phosphor that emits light by ultraviolet light, and driving the gas discharge light-emitting panel so as to compensate for a decrease in light emission intensity of the phosphor due to deterioration of the phosphor The brightness correction material whose reflectance is improved by the above is arranged on at least one member selected from the phosphor layer and a member in the vicinity of the phosphor layer.

  According to the present invention, by using a gas discharge light emitting panel in which a luminance correction material whose reflectance is improved by driving the panel is arranged so as to compensate for a decrease in light emission intensity due to deterioration of the phosphor, Deterioration of the display characteristics of the panel due to a decrease in emission intensity can be suppressed.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following description, the same reference numerals are assigned to the same members, and overlapping descriptions may be omitted.

  FIG. 1 shows an example of a plasma display panel (PDP) as a gas discharge light emitting panel of the present invention.

  The PDP 51 shown in FIG. 1 is disposed on a main surface on the discharge space 31 side of the back plate 2 and a pair of substrates (front plate 1 and back plate 2) arranged so as to face each other through the discharge space 31. And a phosphor layer 3. The phosphor layer 3 includes a phosphor that emits light due to ultraviolet rays generated in the discharge space 31, and a luminance correction material whose reflectivity is improved by driving the PDP 51 so as to compensate for a decrease in emission intensity due to deterioration of the phosphor. In addition.

  In the PDP 51, the light emitted from the phosphor is reflected by the phosphor layer 3 itself and a member in the vicinity of the phosphor layer 3 (for example, the partition wall 21 and the dielectric layer 22), and then passes through the front plate 1 to transmit the light from the PDP 51. Proceed outside. The phosphor layer 3 contains a luminance correction material, and the light is reflected by the luminance correction material, so that the deterioration of the display characteristics of the panel accompanying the deterioration of the phosphor can be suppressed.

  The deterioration of the phosphor progresses when the phosphor is exposed to the discharge environment by driving the panel (lighting the discharge cell). In order to suppress the deterioration of the display characteristics of the panel, it is desired that the reflectance of the brightness correction material be improved along with the deterioration of the phosphor. That is, the brightness correction material is preferably a material that improves the reflectivity when exposed to the discharge environment of the panel. In selecting a specific brightness correction material, a material that does not adversely affect other members included in the panel, for example, a material whose reflectance is improved by irradiation with vacuum ultraviolet rays may be selected. Usually, such a material is a material that can take a plurality of valences and easily undergoes reduction or oxidation.

  FIG. 2A shows an example of a decrease in emission intensity associated with the deterioration of the phosphor. In the example shown in FIG. 2A, the peak intensity in the emission spectrum of the phosphor decreases from the initial state (a) to the degraded state (b). For example, a brightness correction material having reflection characteristics as shown in FIG. 2B may be combined with such a phosphor. In the example shown in FIG. 2B, the reflectance of the brightness correction material is improved from the initial state (a) to the phosphor degradation time (b). FIG. 2C shows a change in light intensity obtained from the discharge cell by combining the phosphor having the emission intensity characteristic shown in FIG. 2A and the brightness correction material having the reflection characteristic shown in FIG. 2B ((a)). Is the initial state, and (b) is when the phosphor is deteriorated). That is, the amount of decrease in light intensity obtained from the discharge cell can be reduced compared to the amount of decrease in light emission intensity of the phosphor shown in FIG. 2A.

  In the example shown in FIG. 2B, the reflectance of the brightness correction material is improved for all wavelength regions, but the reflectance does not necessarily have to be improved for all wavelength regions. The reflectance of the brightness correction material may be improved with respect to at least a part of the wavelength region of the light emitted from the phosphor, and is preferably improved with respect to the wavelength region near the peak wavelength of the light emitted from the phosphor. .

  The brightness correction material only needs to be disposed on at least one member selected from the phosphor layer 3 and a member in the vicinity of the phosphor layer 3. For example, the brightness correction material is at least selected from the phosphor layer 3, the partition wall 21, and the dielectric layer 22. What is necessary is just to arrange | position to one member. The partition wall 21 is usually disposed between the front plate 1 and the back plate 2, and the dielectric layer 22 is usually disposed between the back plate 2 and the phosphor layer 3.

  Specific configuration examples in which the brightness correction material is arranged are shown in FIGS. 3A to 3D. In the example shown in FIG. 3A, the phosphor layer 3 includes a brightness correction material 4. By setting it as such a structure, the brightness | luminance correction material 4 can be arrange | positioned, without adding a new process to the conventional PDP manufacturing process. Moreover, it becomes easy to adjust the content rate of the brightness correction material in the phosphor layer 3 in advance according to the predicted degree of decrease in the emission intensity of each phosphor. When the phosphor layer 3 includes the luminance correction material 4, the content of the luminance correction material 4 in the phosphor layer 3 is usually in the range of 1 wt% to 50 wt%.

  In the example shown in FIG. 3B, the brightness correction material 4 is disposed between the phosphor layer 3 and the dielectric layer 22. In such a configuration, the luminance correction material 4 also functions as a reflective layer described in Japanese Patent Application Laid-Open No. 2001-266755, so that it is possible to improve the extraction efficiency of light emitted from the phosphor. When the brightness correction material 4 is disposed between the phosphor layer 3 and the dielectric layer 22, the thickness of the phosphor layer 3 is preferably thinner than the thickness of the phosphor layer in the conventional PDP. It is preferably in the range of 1 μm to 15 μm.

  In addition, as shown in FIGS. 3C and 3D, the luminance correction material 4 may be disposed on the surface of the partition wall 21 or the surface of the dielectric layer 22. In FIG. 3A to FIG. 3D, the sustain electrode 11, the scan electrode 12, and the address electrode 23 are parallel to each other for easy understanding of the drawings. In an actual PDP 51, as shown in FIG. 1, the sustain electrode 11, the scan electrode 12, and the address electrode 23 are in a relationship orthogonal to each other.

  The specific shape of the brightness correction material 4 is not particularly limited, and may be, for example, a particle shape or a thin film shape. In the case of the particulate brightness correction material 4, the average particle diameter may be in the range of about 1 nm to 10 μm.

  As shown in FIG. 3B, when the brightness correction material 4 is disposed between the phosphor layer 3 and the dielectric layer 22, the light extraction efficiency can be further improved, and therefore the brightness correction material 4 may be a thin film. preferable. The thin-film brightness correction material 4 can be formed, for example, by a method such as screen printing in the same manner as the method for forming the phosphor layer 3, and the thickness thereof is usually in the range of about 1 nm to 40 μm.

The material used for the brightness correction material 4 is not particularly limited, but for example, selected from V, Mn, Cr, Fe, Co, Ni, Cu, Zn, Pd, Ag, Nd, Nb, Mo, W, Ti, Zr, and Al An oxide or carbonate of at least one kind of element may be used. In particular, it is preferable to use at least one selected from TiO ₂ , WCO _3, and MnCO ₃ because the reflectance is easily improved by driving the panel (turning on the discharge cell). Among these, MnCO ₃ is a material that improves the reflectance in the vicinity of a wavelength of 550 nm.

When the oxide of at least one element described above is used for the luminance correction material 4, it is preferable that the oxide is subjected to a reduction treatment. The reduced oxide has a characteristic of partially absorbing visible light due to the presence of an electron level based on oxygen defects. Such an oxide is easily oxidized by driving the panel, and oxygen defects are compensated by the oxidation. Therefore, the reflectivity reduced by the reduction treatment is improved with the driving of the panel. That is, the degree of improvement in reflectivity by driving the panel can be further increased. As the reduced oxide, for example, TiO ₂ , ZrO, Al ₂ O ₃ or the like may be used, and among them, TiO ₂ is preferably used.

  In addition, the brightness correction material 4 may be Ag particles having an average particle diameter in a range of 1 nm to 100 nm, which is a material whose body color is easily changed by oxidation.

The phosphor included in the phosphor layer 3 is not particularly limited. For example, as a phosphor emitting blue light, BaMgAl ₁₀ : Eu ²⁺ (BAM), CaMgSi ₂ O ₄ : Eu ²⁺ , Sr ₃ MgSi ₂ O ₈ : Eu ²⁺ , (SrBa) ₃ MgSi ₂ O ₈ : Eu ^{2+ and the} like. BAM shows a decrease in light emission intensity of about 10% with respect to the initial state by driving for about 2000 hours. Further, for example, as phosphors emitting green light, Zn ₂ SiO ₄ : Mn ²⁺ (ZSM), YBO ₃ Tb ³⁺ , BaMgAl ₁₄ O ₂₃ : Mn ²⁺ , SrAl ₁₂ O ₁₉ : Mn ²⁺ , BaAl ₁₂ Examples include O ₁₉ : Mn ²⁺ , ZnAl ₁₂ O ₁₉ : Mn ²⁺ , LuBO ₃ : Tb ³⁺ , CaAl ₁₂ O ₁₉ : Mn ^2+, and (Y, Gd) BO as a phosphor emitting red light. ₃ : Eu ³⁺ , Zn ₂ (PO ₄ ) ₂ : Mn ²⁺ , YVO ₄ : Eu ³⁺ , Y ₂ O ₃ : Eu ³⁺ , YPVO ₄ : Eu ³⁺ , YVO ₃ : Eu ³⁺ and Y ₂ Examples thereof include SiO ₅ : Eu ³⁺ .

  As a specific combination of the brightness correction material 4 and the phosphor, for example, the following combinations can be considered.

Combination of phosphors in which the luminance correction material 4 is MnCO ₃ and the emission spectrum peak is in the vicinity of 550 nm: As described above, MnCO ₃ is a material that improves the reflectance in the vicinity of the wavelength of 550 nm. Thus, it is possible to further suppress the deterioration of the display characteristics of the panel due to the decrease in the emission intensity of the phosphor. Examples of the phosphor having the emission spectrum peak of the phosphor in the vicinity of 550 nm include the above-described phosphors emitting green light.

  The brightness correction material 4 does not need to be disposed in all the discharge cells in the gas discharge light-emitting panel of the present invention. For example, the brightness correction material 4 is disposed only in the discharge cells in which the emission intensity of the phosphor is greatly reduced by driving the panel. Alternatively, it may be arranged only in a discharge cell including a phosphor layer that develops a specific color. In particular, in the PDP, the amount of decrease in the emission intensity in the blue phosphor layer tends to be large. Therefore, by disposing the luminance correction material 4 in the discharge cell including the blue phosphor layer, the display characteristics of the panel are greatly deteriorated. It can be suppressed.

  The structure and configuration of each member in the PDP 51 and the materials used for each member are particularly as long as the above-described brightness correction material is disposed on at least one member selected from the phosphor layer and the members near the phosphor layer. There is no limitation, and any structure and configuration common to PDPs may be used.

  In the PDP 51 shown in FIG. 1, the display electrode 13 including the sustain electrode 11 and the scan electrode 12, the dielectric layer 14, and the plasma that generates the dielectric layer 14 in the discharge space 31 are formed on the main surface of the front plate 1. A protective layer 15 for protection is disposed. On the main surface of the back plate 2, an address electrode 23, a dielectric layer 22 that protects the address electrode from the plasma, and a partition wall 21 are disposed. The PDP 51 is an AC type PDP having a so-called three-electrode structure. In FIG. 1, the number of electrodes and partition walls in an actual PDP is omitted.

  The material used for the front plate 1 is not particularly limited as long as it has translucency. For example, a glass substrate may be used. The material used for the back plate 2 is not particularly limited. For example, a substrate containing glass and / or metal may be used. Usually, a glass substrate is used for the front plate 1 and the back plate 2.

  On the front plate 1, stripe-shaped sustain electrodes 11 and scanning electrodes 12 are arranged in parallel as display electrodes 13.

  Sustain electrode 11 and scan electrode 12 have a structure in which transparent electrode (sustain electrode) 11a and transparent electrode (scan electrode) 12a, bus electrode (sustain electrode) 11b, and bus electrode (scan electrode) 12b are stacked. is doing. For the transparent electrodes 11a and 12a, ITO (Indium Tin Oxide), tin oxide or the like may be used. For the bus electrodes 11b and 12b, aluminum, copper, silver, a laminate of chromium and copper, or the like may be used. Although not shown, a black film made of glass and black pigment, which is called a black stripe, is provided between the sustain electrode 11 and the scan electrode 12 to improve the black display quality and increase the contrast of the image. . Each electrode and the black film included in the display electrode 13 can be formed on the main surface of the front plate 1 by a technique such as screen printing, for example.

A dielectric layer 14 is disposed on the front plate 1 so as to cover the display electrode 13, and a protective layer 15 is disposed on the dielectric layer 14 (on the discharge space 31 side of the dielectric layer 14). Has been. The dielectric layer 14 serves as a capacitor that accumulates charges when the PDP 51 displays an image. The dielectric layer 14 may be made of a general material for PDP. For example, the dielectric layer 14 has a low content mainly composed of lead oxide (PbO), bismuth oxide (Bi ₂ O ₃ ), phosphorus oxide (P ₂ O ₅ ), or the like. Any layer made of melting point glass may be used. The dielectric layer 14 is formed by using a dielectric paste obtained by kneading a low-melting glass, a resin, and a solvent by printing (for example, screen printing, die coating printing) or transferring (for example, film laminating). It can be formed by coating on 1, drying and firing.

  A common material for the PDP may be used for the protective layer 15 as well, for example, a layer made of MgO. The protective layer 15 can be formed on the dielectric layer 14 by an electron beam evaporation method, an ion plating method, a sputtering method, or the like.

  On the back plate 2, a dielectric layer 22, striped partition walls 21 and striped address electrodes 23 are arranged. The dielectric layer 22 is disposed so as to cover the address electrodes 23, and the partition walls 21 are disposed so as to be parallel to each other. The phosphor layer 3 is disposed between the adjacent barrier ribs 21, and a region divided by the barrier ribs 21 and surrounded by the intersection of the address electrode 23 and the display electrode 13 in the discharge space 31 becomes a discharge cell. The configuration of the address electrode 23 may be the same as the configuration of the bus electrode described above, and the dielectric layer 22 may be the same as the dielectric layer 14. The partition wall 21 may be formed using glass, a pigment, or the like.

  The phosphor layer 3 is obtained by subjecting a paste obtained by dispersing the phosphor in an organic solvent such as α-terpineol containing ethyl cellulose and / or nitrocellulose at a concentration of 5 wt% to 10 wt% by screen printing or line jet. It can apply | coat between the partition walls 21 by the method, and can calcinate and form in the range of 500 to 550 degreeC.

  The front plate 1 and the back plate 2 are arranged so that the protective layer 15 and the partition wall 21 face the discharge space 31, and the striped display electrodes 13 and address electrodes 23 are formed from the main surfaces of the front plate 1 and the back plate 2. They are arranged facing each other so as to be orthogonal to each other. Sealing members made of low-melting glass are disposed on the peripheral portions of the front plate 1 and the back plate 2, and the discharge space 31 is kept airtight. The discharge space 31 is filled with a discharge gas containing a rare gas such as neon or xenon. The pressure of the discharge gas in the discharge space 31 may be in the range of 53 kPa to 79 kPa (400 Torr to 600 Torr), for example.

  In the PDP 51, a video signal voltage is selectively applied to the display electrode 13 to excite phosphors included in the phosphor layer 3, and the excited phosphor emits red, green, or blue, thereby displaying a color image. it can.

  As a method for manufacturing the PDP 51, a general method may be used as a method for manufacturing the PDP.

  The gas discharge light-emitting panel of the present invention is not limited to the PDP as shown in FIG. 1, and is emitted from the phosphor by irradiating the phosphor with ultraviolet rays (particularly, vacuum ultraviolet rays having a wavelength of 200 nm or less) generated by gas discharge. As long as it is a light emitting panel that uses the light to be emitted, there is no particular limitation. Examples of such a light-emitting panel include a liquid crystal panel backlight, a character display, and a lighting panel in addition to the PDP. Among them, the PDP has a large effect on display characteristics due to a decrease in light emission intensity. When the present invention is applied, the obtained effect is great.

  Hereinafter, the present invention will be described in more detail with reference to examples. The present invention is not limited to the following examples.

In this embodiment, MnCO ₃ as the luminance correction materials: Prepare (particulate average particle size 3 [mu] m), by exposing the MnCO ₃ in an environment that simulates the atmosphere of the PDP discharge space, the change in reflectance of the material (Change in reflection spectrum having the wavelength of incident light as a domain) was evaluated. In the comparative example, SiO ₂ (particulate form: average particle diameter 1 μm) was used.

First, the reflection spectra of MnCO ₃ and SiO ₂ were measured. The measurement was performed with a spectrophotometer (manufactured by Shimadzu Corporation: UV2400PC).

  Next, each of the above materials was placed in a vacuum (pressure 500 Pa) and irradiated with vacuum ultraviolet rays (output 200 W) having a wavelength of 147 nm for 4 hours. Such an irradiation test is considered to reproduce a state in which the PDP is driven for about 2000 hours from the degree of deterioration of the phosphor when a similar test is performed on the phosphor.

Next, the reflection spectrum of MnCO ₃ and SiO ₂ after the irradiation test was measured by the same method.

FIG. 4 shows changes in the reflection spectra of MnCO ₃ and SiO ₂ before and after the irradiation test. In each spectrum shown in FIG. 4, (a) shows the initial state, and (b) shows the state after the irradiation test. Further, the reflectance on the vertical axis in FIG. 4 is a value normalized by a barium sulfate film.

As shown in FIG. 4, in the comparative example SiO ₂ , no change was observed in the reflection spectrum before and after the irradiation test, whereas in MnCO ₃ , the wavelength in the range of 500 nm to 600 nm was determined by the irradiation test. In the region and the wavelength region of 620 nm or more, the reflection spectrum changed in the direction in which the reflectance was improved.

Based on this result, a simulation of the obtained light intensity was performed assuming that MnCO ₃ was used as the brightness correction material and ZSM was combined as the phosphor. It was possible to reduce about 3% with respect to the state (the change in the emission intensity of ZSM itself was about 5% with respect to the initial state). In the simulation, a film-like MnCO ₃ (thickness 20 μm) is placed under the phosphor layer (thickness 5 μm), and about 30% of the light emitted from the phosphor is the phosphor layer (ZSM layer). Multiple reflection was performed, and it was assumed that about 70% was multiple reflected by the MnCO ₃ layer.

  According to the present invention, by using a gas discharge light emitting panel in which a luminance correction material whose reflectance is improved by driving the panel is arranged so as to compensate for a decrease in light emission intensity due to deterioration of the phosphor, Deterioration of the display characteristics of the panel due to a decrease in emission intensity can be suppressed.
