Abstract

A plasma display apparatus capable of preventing devices from being damaged by installing a cover so as not to apply locally excessive pressure onto at least one device formed on at least one signal transmission member includes: a Plasma Display Panel (PDP); a chassis base disposed on a rear portion of the PDP; a circuit board disposed on a rear portion of the chassis base to drive the PDP; at least one signal transmission member connecting the PDP to the circuit board to transmit electrical signals therebetween and including at least one device; a reinforcing member including a mounting portion, on which the at least one signal transmission member is disposed and the at least one device installed on the signal transmission members is mounted, at an edge of the chassis base, and at least one boss disposed on the mounting portion; and a cover installed on a rear portion of the at least one signal transmission member to cover the at least one device formed on the at least one signal transmission member, and attached to the at least one boss of the reinforcing member by a coupling unit.

Claims

1. A plasma display apparatus, comprising:

a Plasma Display Panel (PDP);

a chassis base arranged on a rear portion of the PDP;

a circuit board arranged on a rear portion of the chassis base to drive the PDP;

at least one signal transmission member adapted to connect the PDP to the circuit board to transmit electrical signals therebetween and including at least one device;

a reinforcing member including a mounting portion, on which the at least one signal transmission member is arranged and the at least one device installed on the at least one signal transmission member is mounted, at an edge of the chassis base, and at least one boss arranged on the mounting portion;

a cover arranged on a rear portion of the at least one signal transmission member to cover the at least one device arranged on the at least one signal transmission member; and

a coupling unit adapted to attach the cover to the at least one boss of the reinforcing member.

2. The apparatus of claim 1, wherein the reinforcing member comprises a bent end portion of the chassis base.

3. The apparatus of claim 1, wherein the at least one boss comprises a plurality of bosses separated from each other and arranged on the mounting portion.

4. The apparatus of claim 1, wherein the at least one boss is integrally formed with the mounting portion.

5. The apparatus of claim 1, wherein the at least one device is arranged on the mounting portion which is separated from the chassis base to be parallel to the chassis base, and wherein the reinforcing member includes a base portion attached to the chassis base, and a connection portion adapted to connect the base portion to the mounting portion.

6. The apparatus of claim 1, wherein a first thermal conductive medium is arranged between the at least one device on the at least one signal transmission member and the reinforcing member.

7. The apparatus of claim 1, wherein a second thermal conductive medium is arranged between the at least one device on the at least one signal transmission member and the cover.

8. The apparatus of claim 7, wherein the second thermal conductive medium comprises a shock-absorbing material.

9. The apparatus of claim 7, wherein the at least one boss protrudes from the mounting portion to facilitate the cover being adhered to the second thermal conductive medium covering the at least one device.
