  • Publication number: 20180315949
    Abstract: The present invention discloses a top-emitting OLED device, a method of manufacturing the same, and a display panel. The OLED device includes a substrate, an anode layer, an organic functional layer, a cathode layer, and an auxiliary electrode layer sequentially arranged, wherein the auxiliary electrode layer is arranged on the non-light emitting region of the cathode layer, and the material of the auxiliary electrode layer is electrically conductive. The present invention can increase the conductivity of the cathode layer, reduce the voltage difference between the center and the edge of the screen, and improve the display effect without blocking the light emitting region and not affecting the display brightness of the light emitting region.

  • Publication number: 20180123041
    Abstract: Provided is a multilayer-structured organic electroluminescent diode, and a method of manufacturing a hole transporting layer thereof. The hole transporting layer included in the organic electroluminescent diode is a thin film formed through electrochemical polymerization. The method of manufacturing the hole transporting layer includes the steps of: preparing an electrolyte; electro-polymerizing the electrolyte; controlling thickness of an electropolymerized film; and washing and drying the electropolymerized film as obtained. Specific electropolymerization parameters are set to finely regulate a crosslinking degree and reactivity of the electropolymerized film, thereby solving a prior-art problem that the crosslinking degree and reactivity of a polymer or small molecule hole transporting material in a film state cannot be effectively controlled.
