Description

Plasma Display Panel {PLASMA DISPLAY PANEL}

The present invention relates to a plasma display panel, and more particularly, to a plasma display panel for preventing water or foreign matter from being inserted into an internal circuit when using a film type front filter.

Plasma Display Panels (hereinafter referred to as "PDPs") are characterized by emitting phosphors by 147 nm ultraviolet rays generated during discharge of an inert mixed gas such as He + Xe, Ne + Xe or He + Ne + Xe. An image containing graphics is displayed. Such a PDP is not only thin and easy to enlarge, but also greatly improved in quality due to recent technology development. In particular, the three-electrode AC surface discharge type PDP has advantages of low voltage driving and long life because wall charges are accumulated on the surface during discharge and protect the electrodes from sputtering caused by the discharge.

1 is a perspective view showing a discharge cell structure of a conventional PDP.

Referring to FIG. 1, a discharge cell of a three-electrode AC surface discharge type PDP includes a scan electrode Y and a sustain electrode Z formed on the upper substrate 10, and an address electrode formed on the lower substrate 18. X). Each of the scan electrode Y and the sustain electrode Z has a line width smaller than the line widths of the transparent electrodes 12Y and 12Z and the transparent electrodes 12Y and 12Z and is formed at one edge of the transparent electrode 13Y, 13Z).

The transparent electrodes 12Y and 12Y are usually formed on the upper substrate 10 by indium tin oxide (ITO). The metal bus electrodes 13Y and 13Z are usually formed of metals such as chromium (Cr) and formed on the transparent electrodes 12Y and 12Z to reduce voltage drop caused by the transparent electrodes 12Y and 12Z having high resistance. The upper dielectric layer 14 and the passivation layer 16 are stacked on the upper substrate 10 having the scan electrode Y and the sustain electrode Z side by side. In the upper dielectric layer 14, wall charges generated during plasma discharge are accumulated. The protective layer 16 prevents damage to the upper dielectric layer 14 due to sputtering generated during plasma discharge and increases emission efficiency of secondary electrons. As the protective film 16, magnesium oxide (MgO) is usually used.

The lower dielectric layer 22 and the partition wall 24 are formed on the lower substrate 18 on which the address electrode X is formed, and the phosphor layer 26 is coated on the surfaces of the lower dielectric layer 22 and the partition wall 24. The address electrode X is formed in the direction crossing the scan electrode Y and the sustain electrode Z. The partition wall 24 is formed in a stripe or lattice shape to prevent the ultraviolet rays and the visible light generated by the discharge from leaking to the adjacent discharge cells. The phosphor layer 26 is excited by ultraviolet rays generated during plasma discharge to generate visible light of any one of red, green, and blue. Inert mixed gas is injected into the discharge space provided between the upper and lower substrates 10 and 18 and the partition wall 24.

The PDP is time-divisionally driven by dividing one frame into several subfields having different number of emission times in order to implement grayscale of an image. Each subfield is divided into an initialization period for initializing the full screen, an address period for selecting a scan line and selecting a cell in the selected scan line, and a sustain period for implementing gray levels according to the number of discharges.

For example, when the image is to be displayed with 256 gray levels, as shown in FIG. 2, the frame period (16.67 ms) corresponding to 1/60 second is divided into eight subfields SF1 to SF8. As described above, each of the eight subfields SF1 to SF8 is divided into an initialization period, an address period, and a sustain period. The initialization period and the address period of each subfield are the same for each subfield, while the sustain period is increased at a rate of 2 ⁿ (n = 0,1,2,3,4,5,6,7) in each subfield. .

In the PDP driven as described above, a front filter is installed on the upper substrate 10 to shield electromagnetic waves and prevent reflection of external light.

3 is a cross-sectional view schematically showing one side of a conventional PDP.

Referring to FIG. 3, a conventional PDP includes a panel 32 formed by joining an upper substrate 10 and a lower substrate 18, a front filter 30 installed on a front surface of the panel 32, and a panel ( 32, a printed circuit board 36 installed to be attached to the heat sink 34, a back cover 38 formed to surround the back of the PDP, and the front filter 30. And a filter support portion 40 for connecting the bag cover 38 and a support member 42 provided between the front filter 30 and the bag cover 38 so as to surround the filter support portion 40.

The printed circuit board 36 supplies a driving signal to the electrodes of the panel 32. To this end, the printed circuit board 36 includes various driving units not shown. The panel 32 displays a predetermined image in response to a drive signal supplied from the printed circuit board 36. The heat sink 34 dissipates heat generated from the panel 32 and the printed circuit board 36. The back cover 38 protects the panel 32 from external shocks and blocks electromagnetic waves emitted to the rear surface (hereinafter referred to as "EMI").

The filter support 40 electrically connects the front filter 30 to the bag cover 38. Such a filter support 40 grounds the front filter 30 to the bag cover 38 and prevents EMI from being emitted to the side. The support member 42 supports the filter support 40, the front filter 30, the bag cover 38, and the like.

The front filter 30 shields EMI and prevents reflection of external light. To this end, the front filter 30 is an antireflection film 50, an optical film 52, a glass 54, an EMI shielding film 56 and a near infrared (NIR) shielding film as shown in FIG. 58 is provided. Here, in practice, an adhesive layer is formed between the films 50, 52, 54, 56, 58 of the front filter 30 to bond the films 50, 52, 54, 56, 58. In general, the optical film 52 is formed by inserting a specific material into the adhesive layer. Then, the structure of the front filter 30 is slightly changed depending on the manufacturer. For convenience of description, the adhesive layer is not illustrated, and the optical film 52 is represented as a specific layer, and the structure of the front filter 30 which is generally used is exemplified.

The antireflection coating 50 prevents light incident from the outside from being reflected back to the outside to improve the contrast of the PDP. The antireflective film 50 is formed on the surface of the front filter 30. Meanwhile, the antireflection film 50 may be further formed on the rear surface of the front filter 30. The optical characteristic film 52 lowers the luminance of red (R) and green (G) among the light incident from the panel 32 and improves the optical characteristic of the PDP by increasing the luminance of blue (B).

The glass 54 prevents the front filter 30 from being damaged from an external impact. In other words, the glass 54 supports the front filter 30 to prevent the front filter 30 from being damaged from an external impact. The EMI shielding film 56 shields the EMI to prevent the EMI incident from the panel 32 from being emitted to the outside. The NIR shielding layer 58 shields the NIR emitted from the panel 32 to prevent the NIR above the reference from being emitted to the outside so that signals transmitted using the IR, such as a remote controller, can be normally transmitted. Meanwhile, the EMI shielding film 56 and the NIR shielding film 58 may be composed of one layer.

The front filter 30 is electrically connected to the bag cover 38 through the filter support 40 as shown in FIG. 5. In detail, the filter support 40 is connected to the rear surface of the front filter 30 at one end of the front filter 30. In this case, the filter support 40 is electrically connected to at least one of the EMI shielding film 56 and the NIR shielding film 58. That is, the filter support 40 connects the front filter 30 to the bag cover 38 to shield EMI and / or NIR.

This conventional front filter 30 is used for the glass 54 to prevent the front filter 30 from being damaged by the impact from the outside. However, when the glass 54 is inserted into the front filter 30 in this way, the thickness of the front filter 30 becomes thick. In addition, when the glass 54 is inserted into the front filter 30, the weight becomes heavy and the manufacturing cost increases.

In order to overcome this disadvantage, a film type front filter 60 having the glass 54 removed as shown in FIG. 6 has been proposed. The film front filter 60 includes an antireflection film 62, an optical characteristic film 64, an EMI shielding film 66, and an NIR shielding film 68. Here, an adhesive layer is formed between the films 62, 64, 66, and 68 of the film type front filter 60 to bond the films between the films 62, 64, 66, and 68. In general, the optical film 64 is formed by inserting a specific material into the adhesive layer. In addition, the structure of the film-type front filter 60 is slightly changed depending on the company used. For convenience of description, the adhesive layer is not illustrated and the optical characteristic film 64 is represented as a specific layer.

The antireflective film 62 is formed on the surface of the film type front filter 60 to prevent the light incident from the outside from being reflected back to the outside. The antireflection film 62 may be further formed on the rear surface of the film type front filter 60. The optical characteristic film 64 adjusts the red (R) green (G) and blue (B) light balance among the light incident from the panel 32 and improves the color purity of the red (R) to improve the optical characteristics of the PDP. .

The EMI shielding film 66 shields the EMI to prevent the EMI incident from the panel 32 from being emitted to the outside. The NIR shielding film 68 shields the NIR incident from the panel 32. The NIR shielding film 68 prevents the NIR above the reference from being emitted to the outside so that signals transmitted from the remote controller or the like to the panel 32 can be normally transmitted. Meanwhile, the EMI shielding film 66 and the NIR shielding film 68 may be composed of one layer.

Such a film type front filter 60 has an advantage that the film is lighter and thinner than the front filter 30 including the glass 54. In addition, the film type front filter 60 may reduce the manufacturing cost compared to the front filter 30 including the glass 54. However, it is not commercialized due to the grounding problem between the film type front filter 60 and the filter support 40 at present.

Accordingly, an object of the present invention relates to a PDP that prevents water or foreign matter from being inserted into an internal circuit in a film type front filter.

In order to achieve the above object, the PDP of the present invention comprises a panel; A film type front filter installed at the front of the panel; A back cover installed at the rear of the panel; A filter support for electrically connecting the film type front filter and the bag cover; A support member installed to surround edges of the filter support and the film front filter and connected to the bag cover; It is provided between the support member and the film-type front filter in close contact with the support member is provided with a waterproof layer for blocking the water supplied to the rear side of the panel from the front of the panel. The waterproof layer is formed of a material capable of absorbing moisture. The waterproof layer is formed of any one of silicon and rubber. The waterproof layer absorbs the impact applied to the film front filter from the outside to prevent breakage of the film front filter. The PDP of the present invention is a panel; A film type front filter installed at the front of the panel; A back cover installed at the rear of the panel; A filter support for electrically connecting the film type front filter and the bag cover; A support member installed to surround edges of the filter support and the film front filter and connected to the bag cover; And a rectangular body portion tightly fixed to the support member, and an inclined portion having a lower height than the center portion in order to discharge the water toward the outer portion to block the water between the support member and the film-type front filter. It is provided with a waterproof layer. The inclined portion of the waterproof layer is inclined in a curved shape. The inclined portion of the waterproof layer is inclined in a straight line shape. The PDP further includes a shock absorbing portion formed between the waterproof layer and the effective display portion of the panel to absorb the impact applied to the film type front filter.

Hereinafter, exemplary embodiments of the present invention will be described with reference to FIGS. 7 to 12D.

7 is a view showing a film-type front filter grounding method of the PDP according to an embodiment of the present invention.

Referring to FIG. 7, the PDP of the present invention includes a panel 72 formed by joining an upper substrate and a lower substrate, a film type front filter 70 installed on a front surface of the panel 72, and a panel 72. A heat sink 74 installed at the rear, a printed circuit board 76 installed to be attached to the heat sink 74, a back cover 78 formed to surround the back of the PDP, a film type front filter 70 and The filter support part 80 for connecting the bag cover 78 and the support member 82 provided between the film type front filter 70 and the bag cover 78 so that the filter support part 80 may be enclosed are provided.

The printed circuit board 76 supplies a driving signal to the electrodes of the panel 72. To this end, the printed circuit board 76 includes various driving units not shown. The panel 72 displays a predetermined image in response to a drive signal supplied from the printed circuit board 76. The heat sink 74 dissipates heat generated from the panel 72 and the printed circuit board 76. The back cover 78 protects the panel 72 from external shocks and blocks EMI emitted to the rear surface.

The filter support portion 80 electrically connects the film type front filter 70 to the bag cover 78. Such a filter support 80 grounds the film type front filter 70 to the bag cover 78 and prevents EMI from being emitted to the side. The support member 82 supports the filter support 80, the film front filter 70, and the back cover 78.

The film type front filter 70 has a structure as shown in FIG. 6, and is directly attached to the upper substrate of the panel 72 without an air layer. This film type front filter 70 shields EMI and prevents reflection of external light. In addition, the film type front filter 70 adjusts the red (R) green (G) and blue (B) light balance, and improves the color purity of the red (R) to improve the optical characteristics of the PDP. In addition, the film type front filter 70 shields the NIR to prevent malfunction of the remote control. The structure of the film front filter 70 is the same as that of the conventional film front filter 60 shown in FIG.

On the other hand, the filter support portion 80 is grounded on the film type front filter 70 as shown in FIG. The filter support unit 80 is electrically connected to at least one shielding film of the NIR shielding film and the EMI shielding film inside the film type front filter 70. Here, a metal bar (not shown) is formed to be connected to at least one of the NIR shielding film and the EMI shielding film. The filter support unit 80 is installed to be electrically connected to the metal bar to electrically ground the film type front filter 70 to the bag cover 78.

At this time, the filter support unit 80 is connected to the film type front filter 70 in the same structure as the structure shown in FIG. 3 in order to prevent an increase in cost. Therefore, the filter support part 80 is connected to the film type front filter 70 with predetermined fall inclination. That is, since the filter support part 80 is located at a position higher than the film type front filter 70, the end 83 of the filter support part 80 is connected to the film type front filter 70.

However, in this embodiment of the present invention, a predetermined space 84 is positioned between the support member 82 and the film type front filter 70. As such, when the predetermined space 84 is positioned between the support member 82 and the film type front filter 70, foreign matter and water may penetrate into the inside of the PDP to cause a short circuit of the circuit.

In detail, after the PDP is installed, the user of the PDP cleans the film type front filter 70 by using a water mop. At this time, the water remaining in the film type front filter 70 penetrates into the inside of the PDP via a predetermined space 84, and such water may cause short circuits, oxide film formation, and EMI leakage. Can be. In addition, foreign matters or the like may penetrate into the PDP through the predetermined space 84 to cause a phenomenon such as a short circuit.

In order to solve this problem, a waterproof layer 86 is provided between the film type front filter 70 and the support member 82 as shown in FIG. 9. The waterproof layer 86 prevents the inflow of foreign matter and water from the outside. In other words, the waterproof layer 86 prevents water supplied from the outside from being supplied into the inside of the PDP. To this end, the waterproof layer 86 may be formed of a material capable of absorbing water. The waterproof layer 86 absorbs the impact applied to the film front filter 70 from the outside to prevent the film front filter 70 from being damaged. The waterproof layer 86 may be formed of silicon, rubber, or the like.

Meanwhile, the waterproof layer 86 is formed at the lower end (and / or the upper end) of the non-display portion of the panel 72 as shown in FIG. 10A. Referring to FIG. 10A, the waterproof layer 86 includes a body portion 88 fixed to the support member 82, and a curved portion 90 having a curved slope. Body portion 88 is tightly fixed to the support member 82 to prevent water or foreign matter from being inserted from the outside. Curved portion 90 is formed to have a lower height toward the outer portion from the center to discharge the water flowing from the panel 72 toward the outer portion. Therefore, the water flowing in from the panel 72 is not supplied to the inside of the PDP, thereby preventing short circuits, oxide film formation, and EMI leakage. In addition, the waterproof layer 86 absorbs the impact applied to the panel 72, that is, the film type front filter 70, thereby preventing the film type front filter 70 from being damaged.

Here, the waterproof layer 86 formed at the lower end (and / or the upper end) of the non-display portion of the panel 72 may be formed as shown in FIG. 10B. Referring to FIG. 10B, the waterproof layer 86 includes a body portion 92 fixed to the support member 82 and an inclined portion 94 having a linear inclination. Body portion 92 is tightly fixed to the support member 82 in order to prevent the water or foreign matter is inserted from the outside. The inclined portion 94 is formed to have a lower height toward the outer portion from the central portion, that is, formed in a triangular shape to discharge the water flowing from the panel 72 toward the outer portion. Therefore, the water flowing in from the panel 72 is not supplied to the inside of the PDP, thereby preventing short circuits, oxide film formation, and EMI leakage. In addition, the waterproof layer 86 absorbs the impact applied to the panel 72, that is, the film type front filter 70, thereby preventing the film type front filter 70 from being damaged.

In addition, the waterproof layer 86 formed at the lower end (and / or the upper end) of the non-display portion of the panel 72 may have a rectangular shape as illustrated in FIG. 10C. The waterproof layer 86 is tightly fixed to the support member 82 to prevent water or foreign matter from being inserted into the PDP. That is, the waterproof layer 86 absorbs water, prevents water from being supplied into the PDP, and is tightly fixed to the support member 82 to prevent foreign matter from being supplied into the PDP. In addition, the waterproof layer 86 absorbs the impact applied to the panel 72, that is, the film type front filter 70, thereby preventing the film type front filter 70 from being damaged.

In addition, the waterproof layer 86 formed at one end (or both ends) of the non-display portion of the panel 72 may be formed as shown in FIG. 10D. Referring to FIG. 10D, the waterproof layer 86 includes a body portion 96 fixed to the support member 82, and an inclined portion 98 having a lower height toward the central portion from the outer portion. Here, the inclined portion 98 is formed below the body portion 96. Body portion 96 is tightly fixed to the support member 82 to prevent water or foreign matter from being inserted from the outside. The inclined portion 98 is formed to have a lower height toward the center from the outer portion. Such inclined portion 98 allows the water absorbed by itself to be discharged to the outer portion. Therefore, the water flowing in from the panel 72 is not supplied to the inside of the PDP, thereby preventing short circuits, oxide film formation, and EMI leakage. In addition, the waterproof layer 86 absorbs the impact applied to the panel 72, that is, the film type front filter 70, thereby preventing the film type front filter 70 from being damaged.

Meanwhile, in the present invention, as shown in FIG. 11, the waterproof layer 102 and the shock absorbing layer 100 formed between the film type front filter 70 and the support member 82 are provided. The shock absorbing layer 100 is formed adjacent to the central portion of the panel 72. The shock absorbing layer 100 is formed of an elastic material to absorb the impact applied to the film front filter 70 from the outside to prevent the film front filter 70 from being damaged.

The waterproof layer 102 is formed adjacent to the edge of the panel 72. The waterproof layer 102 prevents water, that is, water, from flowing from the panel 72. In other words, the waterproof layer 102 prevents water supplied from the outside from being supplied into the inside of the PDP. To this end, the waterproof layer 102 may be formed of a material capable of absorbing water.

Here, at least one layer of the waterproof layer 102 and the shock absorbing layer 100 is formed at the lower end (and / or upper end) of the non-display portion. In the present invention, for convenience of description, it will be described on the assumption that the waterproof layer 102 and the shock absorbing layer 100 are provided at the lower end of the non-display unit.

Referring to FIG. 12A, the shock absorbing layer 100 is formed in a rectangular shape and closely fixed to the support member 82. Such a shock absorbing layer 100 absorbs the impact applied from the outside to prevent breakage of the film type front filter 70 and to prevent foreign substances from being inserted into the PDP. The waterproof layer 102 is formed in the shape of "s". That is, the waterproof layer 102 is formed to have a high height at the center and a low height at the outer portion to discharge the water flowing from the panel 72 toward the outer portion. Here, the waterproof layer 102 is formed in a straight form.

On the other hand, the waterproof layer 102 may be formed in the form as shown in Figure 12b. Referring to FIG. 12B, the shock absorbing layer 100 is formed in a rectangular shape and closely fixed to the support member 82. Such a shock absorbing layer 100 absorbs the impact applied from the outside to prevent breakage of the film type front filter 70 and to prevent foreign substances from being inserted into the PDP. The waterproof layer 102 has a high height at the center and is formed in the shape of “s” to have a low height at the outer portion to discharge water introduced from the panel 72 toward the outer portion. Here, the waterproof layer 102 is formed in a curved shape.

In addition, the waterproof layer 102 may be formed as shown in Figure 12c. Referring to FIG. 12C, the shock absorbing layer 100 is formed in a rectangular shape and closely fixed to the support member 82. Such a shock absorbing layer 100 absorbs the impact applied from the outside to prevent breakage of the film type front filter 70 and to prevent foreign substances from being inserted into the PDP. The waterproof layer 102 is formed in a semicircular shape. That is, the waterproof layer 102 is formed to have a high height at the center and a low height at the outer portion to discharge the water flowing from the panel 72 toward the outer portion.

In addition, the waterproof layer 102 may be formed as shown in FIG. 12D. Referring to FIG. 12D, the shock absorbing layer 100 is formed in a rectangular shape and closely fixed to the support member 82.
