Abstract
The utility model provides a graphite film with high thermal conductivity. The graphite film with high thermal conductivity is mounted between a display screen and a shielding housing and comprises an insulating layer, a graphite basic body, and a double-face adhesive tape which are successively pasted and superimposed. The graphite film with high thermal conductivity also comprises a wave absorbing layer used for adsorbing electromagnetic radiation. The wave absorbing layer is pasted between the graphite basic body and the double-face adhesive tape in order to reduce the interference of clutter. The wave absorbing layer not only has low thickness and high absorptivity, but also has good heat conducting and dissipating performance. The combination of the wave absorbing layer and the graphite basic body is not only capable of reducing the use of the internal space of a LCD screen, but is also capable of enhancing the integral heat dissipating effect of a product. A filter in a product in the prior art is replaced by the graphite film with high thermal conductivity so that the integral thickness of the LCD screen is not increased.

High conductive graphite film is because its distinctive low-density (with respect to metal species) and high heat radiation conductive coefficient and low thermal resistance become the preferred material that the hyundai electronics series products solves heat radiation heat conduction technology.Yet, some electronic products such as LCD display etc. are owing to the electromagnetic interference that electromagnetic wave or himself electroplax of other frequency sends has formed noise signal, electronic products such as LCD display have been produced bad influence, the serious display effect that also can influence LCD display, in order to reduce interference, generally adopt the filter that to get rid of noise signal in the inner increase of LCD display, like this, make the LCD display usage space increase, have influence on the integral thickness of LCD display.
The utility model content
The purpose of this utility model is to overcome the defective of prior art, provides a kind of LCD display inner space of reducing to use, strengthen the high conductive graphite film that absorbs the clutter effect.
The utility model is achieved in that a kind of high conductive graphite film, be installed between display screen and the shielding case, described high conductive graphite film comprises insulating barrier, graphite matrix and the double faced adhesive tape of pasting stack successively, described high conductive graphite film also comprises the suction ripple layer for absorption of electromagnetic radiation, and described suction ripple layer is pasted and is arranged between described graphite matrix and the described double faced adhesive tape.
Further, described suction ripple layer is the metal level made of metal material or the semiconductor layer of being made by semi-conducting material.
Further, described graphite matrix both sides are provided with the clamping part of being convenient to the finger clamping, the curved shape of described clamping part.
Further, described graphite matrix is synthetic graphite, and described graphite matrix is tabular.
Further, the size dimension of described double faced adhesive tape is corresponding with the size dimension of described insulating barrier, and the gauge of described double faced adhesive tape is less than 0.01mm, and the gauge of described insulating barrier is less than 0.01mm.
The utility model provides a kind of high conductive graphite film, by the suction ripple layer of absorption of electromagnetic radiation is set, to reduce the interference of clutter, inhale ripple layer not only thin thickness, absorptivity height, and also have good heat conduction and heat radiation, the combination of itself and graphite matrix, not only can reduce the use of LCD display inner space, can also strengthen the radiating effect of product integral body, substitute the prior art median filter, make the LCD display integral thickness can not increase.
