Abstract

A plasma display device includes a front protective cover and a back cover that form a chassis for receiving a module in which a plasma display panel is incorporated in a chassis member. The front protective cover includes a front frame having a front frame opening for exposing a front image display region of the plasma display panel, a protective plate attached to the front frame opening of the front frame, and a protective plate pressing bracket that presses the periphery of the protective plate against the edge of the front frame opening of the front frame. A reinforcing frame is disposed between the front frame and the protective plate pressing bracket.

Claims

1. A plasma display device comprising:

a plasma display panel that has a front image display region, a front substrate having a plurality of display electrodes arranged thereon, and a rear substrate having data electrodes arranged thereon, the data electrodes crossing the display electrodes, the front substrate and the rear substrate facing each other so as to form a discharge space therebetween;

a chassis member having a front side and a rear side, the chassis member holding the plasma display panel on the front side and having a driving circuit block for driving the plasma display panel on the rear side; and

a front protective cover and a back cover that form a chassis for receiving a module in which the chassis member and the plasma display panel are incorporated,

wherein the front protective cover includes a front frame, a protective plate, a reinforcing frame and a protective plate pressing bracket,

wherein the front frame has a front frame opening for exposing the front image display region of the plasma display panel, the front frame being mounted to the chassis member,

the protective plate is attached at the front frame opening of the front frame and sandwiched between the reinforcing frame and the protective plate pressing bracket,

the reinforcing frame is disposed adjacent to the front frame and sandwiched between the front frame and the protective plate pressing bracket, and

the protective plate pressing bracket presses a periphery of the protective plate against an edge of the front frame opening of the front frame, and

wherein the reinforcing frame is formed of a resin or a metal to improve a strength of the front protective cover, and

wherein the reinforcing frame has a reinforcing frame opening corresponding to a display region of the plasma display panel and the periphery of the reinforcing frame opening of the reinforcing frame is exposed from the front frame opening of the front frame.

2. A plasma display device comprising:

a plasma display panel that has a front image display region, a front substrate having a plurality of display electrodes arranged thereon, and a rear substrate having data electrodes arranged thereon, the data electrodes crossing the display electrodes, the front substrate and the rear substrate facing each other so as to form a discharge space therebetween;

a chassis member having a front side and a rear side, the chassis member holding the plasma display panel on the front side and having a driving circuit block for driving the plasma display panel on the rear side; and

a front protective cover and a back cover that form a chassis for receiving a module in which the chassis member and the plasma display panel are incorporated,

wherein the front protective cover includes a front frame, a protective plate, a reinforcing frame and a protective plate pressing bracket,

wherein the front frame has a front frame opening for exposing the front image display region of the plasma display panel, the front frame being mounted to the chassis member,

the protective plate is attached at the front frame opening of the front frame and sandwiched between the reinforcing frame and the protective plate pressing bracket,

the reinforcing frame is disposed adjacent to the front frame and sandwiched between the front flame and the protective plate pressing bracket, and

the protective plate pressing bracket presses a periphery of the protective plate against an edge of the front frame opening of the front frame, and

wherein the reinforcing frame is formed of a resin or a metal to improve a strength of the front protective cover, and

wherein the protective plate is sandwiched between the reinforcing frame and the protective plate pressing bracket, so as to be in direct contact with both the reinforcing frame and the protective plate pressing bracket, and

the reinforcing frame is sandwiched between the front frame and the protective plate pressing bracket, so as to be in direct contact with the front frame and the protective plate pressing bracket.
