The present invention relates to a flat panel display, and more particularly, to a flat panel display that shields static electricity and electromagnetic waves by coating a conductive polymer material on a plastic frame.

Generally, there are various types of flat panel displays such as liquid crystal displays (LCDs), field emission displays (FEDs), organic electroluminescense (EL), plasma display panels (PDPs), and the like. -lime) When an inert gas existing between a glass front substrate and a rear substrate is discharged by a high frequency voltage, vacuum ultraviolet rays are generated to emit a phosphor formed therein, thereby realizing an image. .

1 is an enlarged cross-sectional plan view showing main parts of a structure of a plasma display device as an example of a conventional flat panel display.

As shown, the plasma display device excites a phosphor by a case 110 including a front cabinet 111 and a back cover 112 forming an outer appearance, and a fluorescent substance by vacuum ultraviolet rays caused by gas discharge inside the case. The plasma display panel 120 is provided.

In addition, to drive and control the plasma display panel 120, a driving device 130 including a PCB on which circuit elements are mounted, and connected to the driving device 130 to dissipate heat generated when driving the plasma display device. The heat sink 140 and a filter 150 formed by attaching a film to a transparent glass substrate (not shown) at a predetermined interval in front of the plasma display panel are provided.

In addition, a finger spring gasket 160 and a filter supporter 170 which support the filter 150 and are electrically connected to the metal back cover, the driving device 130 and the plasma display panel And a module supporter 180 supporting the 120.

Looking at the manufacturing process of the conventional plasma display device having such a structure, first, after manufacturing the plasma display panel 120 to implement the image, and then the heat sink 140 formed on the back of the plasma display panel 120 and the driving device 130, etc. are assembled. Thereafter, the case 110 forming the external shape is assembled to manufacture a plasma display device as a finished product.

In addition, the conventional flat panel display device is provided with a metal frame (not shown) such as iron or aluminum to support the panel 120 and the driving device 130.

However, the conventional flat panel display device as described above has problems of metal corrosion such as rusting in iron and whitening in aluminum.

In addition, due to charged charges that are not completely shielded from the electromagnetic wave (EMI) on the panel surface, sparks may be generated when contacting body parts such as hands when carrying, storing and using the flat panel display. It may cause electrical damage to the panel or adversely affect the physical health of the panel, there was also a problem in that the stability of the work and the reliability of the product.

Accordingly, the present invention is to solve the above problems, by coating a conductive polymer material on the plastic frame, to eliminate the problems of metal corrosion caused in the conventional frame, and to shield the electrostatic and electromagnetic waves The purpose is to provide.

In order to achieve the above object, a flat panel display device according to the present invention includes a flat panel display panel and a frame supporting the flat panel display panel, wherein the frame is formed of a plastic resin, and a conductive polymer material is coated on the surface thereof. It is characterized by.

It is preferable that the frame has thermal conductivity. A driving circuit board is further formed on the rear surface of the flat panel display panel, and the frame is electrically connected to the driving circuit board.

The conductive polymeric material comprises polythiophene, more preferably non-toxic.

Therefore, the present invention eliminates the problem of the metal corrosion, and protects the panel and the body from electric wave to improve the stability of the work and the reliability of the product.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.
