Plasma display panel including TCC EMI filter, and/or method of making the same
View Patent ↗A plasma display panel (PDP) includes an EMI filter supported by a glass substrate for blocking/shielding substantial amounts of electromagnetic waves, with the filter being supported by a side of the substrate opposite a viewer. In certain example embodiments, a black frit and a silver frit comprise a filter frame and are supported by the filter such that the filter is closer to the glass substrate than either or both of the frits. Alternatively, in certain example embodiments, a conductive black frit comprises a filter frame and is supported by the filter such that the filter is closer to the glass substrate than the frit. The filter has high visible transmission, and is capable of blocking/shielding electromagnetic waves. Advantageously, a transparent conductive coating (TCC) can be coated on a stock, non-cut glass sheet.
1. A plasma display device, comprising:
a plasma display panel;
an electromagnetic interference (EMI) filter provided at a front portion of the plasma display panel, the EMI filter including a multi-layer silver-inclusive transparent conductive coating (TCC) supported by an inner surface of a glass substrate;
an inner black frit frame disposed around a portion of the glass substrate that corresponds to a visible portion of the plasma display panel; and
an outer silver frit frame disposed around the inner black frit frame at the periphery of the glass substrate,
wherein the TCC is provided closer to the glass substrate than the inner and outer frit frames, and
wherein the inner black frit frame is non-conductive and the outer silver frit frame is conductive.
2. The plasma display device of claim 1 , wherein the TCC comprises at least three Ag layers.
3. The plasma display device of claim 1 , wherein the black frit frame and the silver frit frame at least partially overlap.
4. The plasma display device of claim 3 , wherein the silver frit frame is substantially unperceivable by a viewer of the plasma display device.
5. The plasma display device of claim 1 , wherein the glass substrate and the TCC combined have a visible transmission of at least about 55%.
6. A display device, comprising:
a display panel;
an electromagnetic interference (EMI) filter provided at a front portion of the display panel, the EMI filter including a multi-layer silver-inclusive transparent conductive coating (TCC) supported by an inner surface of a glass substrate;
an inner black frit frame disposed around a portion of the glass substrate that substantially corresponds to a visible portion of the display panel; and
an outer silver frit frame disposed around the inner black frit frame,
wherein the TCC is provided closer to the glass substrate than the inner and outer frit frames, and
wherein the inner black frit frame is non-conductive and the outer silver frit frame is conductive.
7. The display device of claim 6 , wherein the TCC comprises at least three layers comprising Ag.
8. The display device of claim 6 , wherein the black frit frame and the silver frit frame at least partially overlap.
9. The display device of claim 6 , wherein the silver frit frame is substantially unperceivable by a viewer of the display device.
10. The display device of claim 6 , wherein the glass substrate and the TCC combined have a visible transmission of at least about 55%.
