Abstract
The present disclosure relates to an OLED device and a method for preparing the same. The method includes: providing an OLED basic device; forming a hydrophobic layer selectively covering a light emitting side surface of the OLED basic device by an ink jet printing method; forming an optical coupling efficiency enhancing layer on an area of the light emitting side surface in a selective atom precipitation way, which may not be covered by the hydrophobic layer. The optical coupling efficiency enhancing layer is formed between adjacent hydrophobic layers to form a periodic distribution array, thereby improving the optical coupling efficiency of the OLED device.
