Oled structure with a u-shaped anode and fabricating method of the same

A fabricating method of an organic light-emitting diode (OLED) structure with a U-shaped anode, comprising:

• providing a substrate comprising a pixel area and an external circuit area;
• forming a first metal material layer covering the substrate;
• patterning the first metal material layer to form a plurality of first anodes in the pixel area, a plurality of dummy metal blocks between the pixel area and the external circuit area, and a first metal layer in the external circuit area;
• forming a dielectric layer covering the plurality of first anodes, the plurality of dummy metal blocks and the first metal layer;
• patterning the dielectric layer to form a plurality of openings in the dielectric layer, wherein each of the plurality of first anodes and the first metal layer are respectively exposed through one of the plurality of openings, and the plurality of dummy metal blocks are not exposed from the dielectric layer;
• forming a second metal material layer covering the dielectric layer and covering the plurality of openings;
• and
• removing the second metal material layer outside of the plurality of openings to segment the second metal material layer which remains into a plurality of second anodes and a second metal layer, wherein each of the plurality of second anodes contacts one of the plurality of first anodes, and the second metal layer contacts the first metal layer.
