Abstract: The present invention provides an OLED packaging method and an OLED package structure. The OLED packaging method of the present invention is such that a silicon-doped diamond-like carbon layer and a diamond-like carbon scattering layer are both provided in an OLED package structure so that the silicon-doped diamond-like carbon layer may provide an effect of blocking external moisture and oxygen and the diamond-like carbon scattering layer is used to provide an effect of increasing light transmission rate, whereby it is possible to greatly extend the service life of the OLED device and also to ensure a relatively high light output efficiency of the OLED device.
