The material of the metal layer 404 is preferably gold, silver, copper, or an alloy thereof in view of thermal conductivity, but the material of the metal layer 404 is most preferably copper, brass, or red copper in view of cost.
The improved bending pad 4 in the above embodiment not only plays a role of fixing the main body of the flexible panel 3, but also has a role of heat conduction, and compared with a plastic material, the advantage of heat conduction of the metal layer 404 is more obvious, and by using it as a medium between the heat conduction film and the driving chip 2, the heat of the driving chip 2 can be more effectively conducted to the heat-conducting film, but at the same time, in order to achieve the same effect as using a plastic substrate without causing the problem of film printing, in the embodiment of the present invention, the selection of the substrate thickness of the metal layer 404 is compared, and it is found that the effect after the bonding is affected by the too thin metal layer 404, and metal level 404 is too thick can be unfavorable for crooked gasket 4 to cut, and the edge can appear cutting badly, causes the membrane seal, and through the material object with the trial production verification, the thickness of the metal level 404 of selecting at last is 0.05mm-0.075mm, and this thickness range is applicable to the metal level 404 of copper material more.
In order to further improve the heat dissipation effect of the curved pad 4, a nano-coating 406 is formed on the surface of the metal layer 404, and the nano-coating 406 is made of a nano-carbon material. The nano carbon material is a carbon material with at least one dimension smaller than 100nm of the size of a disperse phase, and the disperse phase can be composed of carbon atoms, can also be composed of heterogeneous atoms (non-carbon atoms) and even can be nano holes. Nanocarbon materials include, but are not limited to, carbon nanotubes, carbon nanofibers, and nanocarbon spheres. For metals, the longitudinal heat transfer capacity is strong, but the lateral heat radiation capacity is poor, whereas for most carbon materials, the lateral heat radiation capacity is strong. In this application with carbon nanometer coating at the surface formation nanometer coating 406 of metal level 404, its thickness can be set for as required, usually in the micron level can, the formation mode of coating includes but not limited to coating and UV solidification, obtains to have the metal level 404 of nanometer coating 406 and can promote coefficient of heat conductivity to make full use of carbon atom's heat radiation advantage, it becomes more smooth and easy to let whole heat conduction process, and the heat conduction effect is better. Specifically, the nano-carbon material needs to be uniformly coated on the surface of the metal layer 404, and the nano-carbon material can convert heat energy into infrared radio frequency by utilizing the high thermal conductivity among carbon atoms and the high thermal radiation efficiency of the carbon atoms, and the nano-coating 406 has a large area, light weight, good thermal conductivity, thermal convection and thermal radiation, and the overall heat dissipation effect is greatly improved compared with the metal layer 404 substrate.
In order to obtain a larger heat dissipation area, under the condition that the space structure and design requirements of the display module allow, the orthographic projection of the metal layer 404 on the plane where the driving chip 2 is located completely covers the driving chip 2, so that heat at any position of the driving chip 2 can be directly conducted to the metal layer 404, and is transferred to the heat dissipation film 5 through the relatively larger area of the metal layer 404, so that the heat is dissipated outwards.
It should be noted that, in the curved gasket 4, the first thermal conductive adhesive 403 and the second thermal conductive adhesive 405 may be selected from various thermal conductive adhesive products in the prior art, and the raw materials of the first thermal conductive adhesive include, but are not limited to, colloidal materials such as silica gel, acrylic adhesive, polystyrene adhesive, and polyester, and those skilled in the art may specifically select the first thermal conductive adhesive 403 and the second thermal conductive adhesive 405 according to the thermal conductive and bonding requirements.
