Plasma display device
A plasma display having improved heat sink efficiency and reduced manufacturing cost includes a heat sink member made of an inexpensive graphite material having excellent thermal conductivity instead of a more expensive aluminum protective plate or a heat sink plate. The heat sink member serves as a heat sink of a Tape Carrier Package (TCP), an Intelligent Power Module (IPM), and other elements producing considerable amounts of heat.
1. A plasma display, comprising:
a Plasma Display Panel (PDP) to display images on a first surface thereof, the images being generated by a gas discharge;
a chassis base arranged on a second surface of the PDP, the chassis base supporting the PDP;
a driving circuit substrate arranged on the second surface of the chassis base;
a Tape Carrier Package (TCP) having at least one element mounted on a connection cable electrically coupling the driving circuit substrate to the PDP; and
a heat sink member arranged on the second surface of the TCP and contacting the at least one element, the heat sink member including a graphite layer, a holder to support the graphite layer, and a coating layer covering an area including a surface of the graphite layer opposite to the at least one element.
2. The plasma display of claim 1 , wherein the chassis base comprises a chassis reinforcing member, the at least one element being supported by the chassis reinforcing member.
3. The plasma display of claim 1 , wherein the chassis base comprises a bent part on an end thereof, the at least one element being supported by the bent part.
4. The plasma display of claim 1 , wherein the holder surrounds part of the graphite layer.
5. The plasma display of claim 1 , wherein a vertical end surface of the holder is “C” shaped and has a fixing groove on one surface thereof, the graphite layer being supported by being inserted into the fixing groove.
6. The plasma display of claim I, wherein the holder comprises a material selected from a group consisting of an iron alloy, aluminum alloy and stainless steel alloy.
7. The plasma display of claim 1 , wherein the coating layer covers a surplus area except for an area where the graphite layer is surrounded by the holder.
8. The plasma display of claim 1 , wherein the coating layer entirely covers a surface of the graphite layer.
9. The plasma display of claim 1 , wherein the coating layer comprises an elastic layer having a better elastic force than that of the graphite layer.
10. The plasma display of claim 9 , wherein the elastic layer comprises a material selected from a group consisting of a paint coating layer, a thermal grease layer and a plastic coating layer.
11. The plasma display of claim 1 , wherein the graphite layer is supported by being affixed to the holder by an adhesive agent layer.
12. The plasma display of claim 2 , wherein a thermally conductive medium is interposed between the chassis reinforcing member and the at least one element.
13. A plasma display, comprising:
a Plasma Display Panel (PDP) to display images on a first surface, the images being generated by a gas discharge;
a chassis base arranged on a second surface of the PDP, the chassis base supporting the PDP;
a driving circuit substrate arranged on the second surface of the chassis base and including an Intelligent Power Module (IPM); and
a heat sink member arranged on the second surface of the IPM and contacting the IPM, the heat sink member including a graphite layer, a holder to support the graphite layer, and a coating layer covering an area of the graphite layer including a surface opposite to the IPM.
14. The plasma display of claim 13 , wherein the holder surrounds a part of the graphite layer.
15. The plasma display of claim 13 , wherein a vertical end surface of the holder is “C” shaped and has a fixing groove on one surface, the graphite layer being supported by being inserting into the fixing groove.
16. The plasma display of claim 13 , wherein the holder comprises a material selected from a group consisting of iron alloy, aluminum alloy and stainless steel alloy.
17. The plasma display of claim 13 , wherein the coating layer covers a surplus area except for an area where the graphite layer is surrounded by the holder.
18. The plasma display of claim 13 , wherein the coating layer entirely covers the surface of the graphite layer.
19. The plasma display of claim 13 , wherein the coating layer comprises an elastic layer having a better elastic force than that of the graphite layer.
20. The plasma display of claim 19 , wherein the elastic layer comprises a material selected from a group consisting of a paint coating layer, a thermal grease layer and a plastic coating layer.
