Teijin manufactured LED backlight with bottom plate

Teijin DuPont films using white PEN (PolyethyleneNaphthalate, polynaphthalene two terephthalate) film "Teonex" succeeded in producing LED backlight with bottom plate. In particular, the film is sandwiched between 2 PEN films to be used as a substrate for the copper foil, and then the copper wiring is installed on the LED. LED can be used as a support substrate and reflective film. The company in the "FPDInternational2008" (from October 29th to 31, the Yokohama Exhibition Center) showed its prototype.

PEN film is characterized by high temperature and mechanical strength. The utility model has the advantages of supporting the reflow soldering resistance of about 260 DEG C, and in addition, the heat resistant temperature is about 180 DEG C for continuous use.

About use of white PEN film, in addition to the LED backlight plate with film, Teijin DuPont films also cited the solar cell base (BackSeat). Solar cell base, the current use of PET (PolyEthyleneTerephthalate, polyethylene terephthalate). The company will use the characteristics of heat resistance and mechanical strength higher than PET, to explore the use of PEN in place of the existing solar cell base, as well as the pigment sensitized solar cell floor, etc..
