Document Type and Number:
WIPO Patent Application WO/2021/088141
Kind Code:
A1
Abstract:
An organic light emitting diode panel and a manufacturing method therefor. The organic light emitting diode panel comprises a substrate (100); a pixel definition layer (160) provided on a part of the substrate (100); an organic light emitting diode device and an auxiliary cathode contact device which are provided on the substrate (100) and are spaced from each other by the pixel definition layer (160), the organic light emitting diode device comprising an anode layer (150A), a hole injection layer (170), a hole transport layer (180), a light-emitting layer (190) and an electron transport layer (210) which are sequentially formed on a part of the substrate (100), the auxiliary cathode contact device comprising an auxiliary cathode (150B) and a conductive contact (300) which are sequentially formed on another part of the substrate (100), and the conductive contact (300) comprising a conductive mixture composed of the electron transport layer (210) and a solvent material (200) for dissolving the electron transport layer (210); and a transparent electrode layer (220) covering the electron transport layer (210), the pixel definition layer (160) and the conductive contact (300).
