Abstract:
A method for continuously preparing organic light emitting diode (OLED) by using thermal transfer film is revealed. At least two thermal transfer layers are transferred onto a substrate in turn by thermal transfer printing for overcoming shortcomings of the conventional vacuum evaporation including complicated processes and low material efficiency. Only less than 50% material reaches the substrate after the vacuum evaporation.
