【先前技術】 近來，高清晰度電視（HDTV)的開發已經部分完 成。隨著HDTV之改進研究的持續進行，圖像顯示器（或 畫面顯示器）變得更加重要。如已知，圖像顯示器的類 型可以包括陰極射線管（CRT)、液晶顯示器（LCD)、 真空螢光顯示器（VFD)、電漿顯示面板（在下文中，稱 爲 “PDP”）等。 但是，在技術上還沒有研究出滿足HDTV的顯示 器。因此，人們在不同領域正以互補的方式開發該等顯 示器。 上述圖像顯不器中的PDP適於藉由氣體放電的方 式顯不圖像。PDP具有最高的解析度和對比度及快速的 回應速度，並且適於顯示出大面積的圖像。因此[Previous Technology] Recently, the development of high-definition television (HDTV) has been partially completed. As HDTV improvement studies continue, image displays (or picture displays) become more important. As known, the type of image display may include a cathode ray tube (CRT), a liquid crystal display (LCD), a vacuum fluorescent display (VFD), a plasma display panel (hereinafter, referred to as "PDP"), and the like. However, a display that satisfies HDTV has not been technically developed. As a result, such displays are being developed in complementary ways in different fields. The PDP in the image display device described above is suitable for displaying images by a gas discharge method. PDP has the highest resolution and contrast, fast response speed, and is suitable for displaying large area images. therefore

Figure 2 is a cross-sectional view showing the state of a conventional PDP after coupling. 1 and 2, the PDP has a front substrate 10, and the front substrate 10 is a display surface on which an image can be displayed; and a rear substrate 20 constituting a rear surface. The front substrate 10 and the rear substrate 20 are lightly connected in parallel at a distance from each other. # The sustaining electrodes 11 are arranged in pairs at the bottom of the front substrate 10, and the sustaining electrodes 11 are used to maintain the radiation of the cell by the alternating discharge in one pixel. The sustain electrode 11 is used to limit the discharge current, and is covered with a dielectric layer 12 to insulate between the electrode pairs. A protective layer 13 is formed on the opposite surface of the surface of the dielectric layer 12 covering the sustain electrode 11. The rear substrate 20 includes a plurality of discharge spaces, that is, bar-shaped barrier ribs 21 for forming a unit, and a plurality of address electrodes 22 for performing address discharge at positions where the address electrodes 22 and the sustain electrodes 11 cross to Generate real I outside lines. At this time, the anti-seeding bars 21 are arranged in parallel with each other. The address electrodes 22 are arranged parallel to the barrier ribs 21. In addition, an R.G.B light-filling layer 23 that emits visible light for displaying an image in the address discharge is coated on the upper surface of the rear substrate 20 except for the top of the barrier ribs 21. However, this PDP has a problem that an afterimage is generated. For example, if 200527467 the first image is switched to the second image after being opened for a predetermined time, the time that the first image disappears is extended by several minutes to tens of minutes. Moreover, even if the images are switched, the previous image and the subsequent images overlap. As a result, the quality of the daytime surface is deteriorated. In addition, the problem with the conventional PDP is that it generates a lot of noise, is easily affected by vibration, and is quite heavy. SUMMARY OF THE INVENTION Therefore, an object of the present invention is to solve at least the problems and disadvantages of the prior art. An object of the present invention is to provide a plasma display panel suitable for absorbing vibration and noise and suitable for light weight.

Layer, and the sheet and the base plate are opposite to each other, wherein the hardness of the sheet is Asker C 15-30, and the thickness from the surface of the base plate opposite to the sheet to the sheet ranges from 0.2 to 1 mm. The advantage of the present invention is that it can reduce the afterimage time. In addition, the present invention uses low-hardness and lightweight flakes. Therefore, it is possible to absorb the vibration and noise of the PDP, make the PDP lightweight, and reduce the sheet material. [Embodiment] The preferred embodiment of the present invention will be described in more detail with reference to the drawings. In one aspect, the present invention provides a plasma display panel including a panel unit having a top plate and a bottom plate, a frame supporting a circuit, and a conductive material formed between the panel unit and the frame. The conductive material is a conductive sheet having at least part of an adhesive strength. An insulating sheet to prevent electromagnetic waves generated from the panel from affecting peripheral elements or circuits is attached to one side of the conductive material. A sheet having toughness is attached to one side of the conductive material. 10 200527467 The conductive material is a metal-coated film, which is not formed separately, but is coated on one side of the panel in the form of a film. The metal-coated fine is formed by a ru method, a painting method, or a sputtering method. The conductive material is formed by a printing method using a conductive paste. The conductive material is formed by using one or more of silver (Ag), steel (Cu), and inscription (A1).忒 The conductive material is laminated in a floating state. The conductive material is grounded to peripheral components or circuits. In another aspect, the present invention provides a plasma display panel including a sheet containing one or more of silicon, ethylamino foam and acrylic, and at least one metal layer laminated on the sheet. The sheet is provided between the panel unit and the frame, and the sheet has a laminated metal layer thereon.谠 PDP compound includes an adhesive layer for bonding to a metal layer and a panel unit. 200527467 The total thickness of the adhesive layer, metal layer and sheet ranges from 0.2 to 1 mm. The total thickness of the adhesive layer, metal layer and sheet ranges from 0.6 mm to 0.95 mm. The urethane foam includes multiple Fine holes. _ The fine pores are filled by one of Shi Xi and acrylic acid. The hardness of the adhesive layer, metal layer and flakes is Asker C 15-30. The hardness of the adhesive layer, metal layer and flakes is Asker C 20-30. The metal layer includes one or more of silver (Ag), copper (Cu), and aluminum (A1). • The thickness of this metal layer is from 0.01mm-0.3mm. The metal layer includes a plurality of slits. The width of the slit ranges from 0.05 mm to 1 mm. The acrylic acid is viscous. 12 200527467 This sheet includes multiple fine pores entrained in viscous acrylic acid. * The PDP of the present invention includes flakes having one or more of Shi Xi, urethane foam, and acrylic acid. In another aspect, the present invention provides a plasma display panel including a sheet of one or more of 3 Shi Xi, urethane foam, and acrylic, and a sheet formed between the sheet and the base plate opposite to each other. At least one layer of φ * general layer 'wherein the hardness of the sheet is AskerC 15_30, and from the surface of the bottom plate opposite to the sheet to the thickness of the sheet Fan 2 G 2 · 1 side. FIG. 3 is an exploded perspective view showing the structure of the pDp according to the first embodiment of the present invention. Referring to FIG. 3, the PDP of the present invention includes a panel unit 11 having a top plate lu and a bottom plate 113 laminated on the panel unit 11. 〇 Bottom plate ηη a metal layer 141 on the lower surface, a sheet 120 formed on the lower surface of the metal layer 141, and a metal layer 141 and a cymbal 120 disposed opposite to the panel unit 110, and the metal layer 141 and the cymbal 120 are positioned thereon and the panel unit No frame between no. The metal layer 141 can be formed on the lower surface of the base plate 113 by applying a conductive paste on the glass substrate of the base plate 113, or by coating a metal on the glass substrate of the base plate 113 by a sputtering method or the like. The metal layer 141 is formed on the base plate 113 in a floating state. The metal layer 141 has an influence on the charge introduced into the bottom plate 113 to improve the waveform stability of the panel unit 110. It also improves the charge characteristics to perform stable operation. Similarly, if a metal layer ⑷ is formed on the panel unit no, and then electrically floated, the amount of charge that generates an afterimage is reduced, and thus the afterimage is reduced. Moreover, the 'metal layer 141 can be grounded to a ground voltage (gnd), thereby inducing discharge of the residual charge. The sheet 120 may be formed using a material having low thermal resistance, heterogeneity, and moderate adhesive strength with the metal layer, for example, one or more of heteroacrylic acid, a phase, and ethyl aminoglycolate. .

FIG. 7 is a cross-sectional view showing a pDp sheet 16 200527467 according to a fifth embodiment of the present invention. Referring to FIG. 7, the sheet for a PDP of the present invention includes one of silicon, urethane foam, and acrylic acid. One or more base material sheets 200, and a metal layer and an adhesive layer 202 laminated on the base material sheet 200 in this order. The sheet used for PDP needs to have Asker C hardness of 15-30, preferably 20-25, so that it can be used as a damper to absorb vibration and noise, and have low thermal resistance for high thermal conductivity. For this purpose, porous materials can be used: low thermal resistance and w-elasticity (which has viscosity and multiple fine pores) to form a basic material sheet 2GG, such as a porous material composed of a combination of urethane g beads and Shi Xi , Or prospective acrylic material with a porous structure formed by foaming. The metal layer 200 may be formed using a metal having high conductivity, such as aluminum (A1), copper (Cu), or silver (Ag). The 3 outer 'sheet for PDP must be made as thin as possible to make the PDP lighter and save material costs. In order to achieve the above-mentioned hardness conditions and light weight, the total thickness of the sheet including the metal layer, the adhesive layer, and the base material sheet is required to be 0.2-lmm, preferably 0.6 traces. If the total thickness range of the sheet is less than or equal to G.2mm, the noise and vibration characteristics of the panel can be reduced. In addition, the thickness of the metal layer 201 is required to be 0.01 mm to 0.3 mm, and preferably 0.02 mm to 0.03 mm. At the same time, taking advantage of advanced thin-film technology, 17 200527467 takes into account the current level of manufacturing technology, there is no problem in manufacturing thin sheets with a total thickness of 0.9 mm or less. If the total thickness of the sheet is reduced, the heat dissipation effect can be improved and the cost of the material can be significantly reduced. For example, experiments have shown that if the thickness of the sheet is reduced by 0.1 mm, the temperature of the PDP is reduced by 2 ° c or more, and if the thickness of the sheet is reduced from 1.2 mm to 0.9 mm, the material cost of the sheet is reduced by about 10%. In the present invention, in order to satisfy the above-mentioned hardness conditions, the surface energy may be enhanced by increasing the foam density of the base material sheet 200, and the damping effect of the base material sheet 200 on vibration, vibration, and noise may be optimized by improving porosity. If the base material sheet 200 is made of a punctiform amino amino acid material having a porous structure, a plurality of fine pores 20ia are entrained therein through foaming, as shown in FIG. 8, the base material sheet 200 and metal The layers 201 can be adhered to each other without the need for an additional adhesive. In the same manner, if the base material sheet 200 is made of foamed viscous acrylic acid, the base material sheet 200 and the metal layer 201 can be bonded to each other without the need for an additional adhesive, as shown in FIG. 7. Conversely, if the base material sheet 200 is made of silicon, a porous material (in which a silicon and urethane foam is combined), a foamed acrylic acid (in which a urethane foam is combined), etc., An additional adhesive 203 is formed between the base material sheet 200 and the metal layer 201 to bond the base material sheet 20000 200527467 and the metal layer 201 as shown in FIG. 9. The adhesive layer 202 formed on the metal layer 201 can be formed using any known adhesive (such as an acrylic acid-based adhesive), and it is used to adhere the metal layer 201 to the above-mentioned embodiment pDp on the glass substrate of the bottom plate of the panel unit. Further, an rdeasing paper that can be easily separated from the adhesive layer 202 may be formed on the adhesive layer 202 to prevent contamination. A method of bonding the sheet to the glass substrate of the bottom plate of the panel unit will be described below. When the release paper on the adhesive layer 202 is torn off, the sheet as shown in Fig. 7 is adhered to the glass substrate of the panel unit by a lamination method using pressure and / or heat. During this lamination process, an air layer or air bubbles should not be included between the sheet as shown in Fig. 7 and the glass substrate of the bottom plate of the panel unit. For this purpose, as shown in FIGS. 10a and 10b, a plurality of slits 201a are formed in the metal layer 201, and these slits are used to discharge the sheets and panel units during the process of laminating the sheets and panel units. Air exists between. The slits 201a can have a linear shape, as shown in Fig. 10a, or other shapes, such as "+". The width of the slits 20a is preferably 0.05mm-lmm, so that the air can flow smoothly. Pass, as shown in Fig. 0 19 200527467 At the same time, the sheet for PDP according to the present invention can contain only a basic material sheet 200 made of a viscous urethane having a porous structure, without a metal layer 201 and the adhesive layer 202. In this case, in order to achieve the above-mentioned hardness conditions and light weight, the thickness of the base material sheet 2000 is 1 mm or less. In addition, the sheet for PDP according to the present invention can use silicon and gas. It can be formed by the combination of a methyl ethyl acetate foam bed without the metal layer 201, or a multilayer sheet having a porous base material sheet 200 and an adhesive layer 202 made of foamed silicon or foamed acrylic acid. In this case, the total thickness of the adhesive layer 202 and the base material sheet 200 must be less than or equal to 1 mm in order to achieve the above-mentioned hardness and lightness conditions. Also, the 'base material sheet 200' exhibits a color between white and black. Adjustment, so that it can absorb the light scattered back from the panel unit through the rear glass substrate to reduce the decline in the contrast of the picture quality. Here, the degradation of the quality of the daytime surface caused by the light that is reflected backwards to the panel unit. To this end The base material sheet 200 contains a carbon-based paint added thereto, and thus exhibits a gray hue. As described above, according to the present invention, a conductive material is formed on the lower surface of the bottom plate of the panel. Therefore, it is appropriately controlled The charge introduced to the base plate is used to improve the waveform stability of the panel. Moreover, the charge characteristics are improved to perform stable operation. Therefore, the present invention has the advantage that it can reduce the residual image time 20 200527467 image time.
