Title:
FABRICATION METHOD FOR OLED DISPLAY PANEL AND OLED DISPLAY PANEL
Document Type and Number:
WIPO Patent Application WO/2020/232819
Kind Code:
A1
Abstract:
Provided by the present invention are a fabrication method for an OLED display panel and an OLED display panel. The method comprises the following steps: providing a base substrate, and forming on the base substrate a plurality of anodes arranged in an array and an auxiliary electrode located within an interval region of the plurality of anodes; forming a pixel defining layer on the base substrate, the plurality of anodes and the auxiliary electrode, and forming on the pixel defining layer a plurality of first openings that respectively correspond above the plurality of anodes as well as a second opening corresponding above the auxiliary electrode; forming an OLED light-emitting layer covering the entire surface on the auxiliary electrode, the pixel defining layer, and the plurality of anodes; performing UV illumination on the OLED light-emitting layer; and forming cathodes distributed on the entire surface on the OLED light-emitting layer. By means of UV illumination, the electrical current conductivity of an electron transmission material in the OLED light-emitting layer may be improved, conductivity obstacles between the auxiliary electrode and the cathodes may be eliminated, and voltage drop enhancement effect may be improved.
