Abstract
The present application relates to an OLED light-emitting unit for use in a top-emission OLED substrate, which includes an anode, a cathode, and an organic functional layer arranged between the anode and the cathode. The anode includes a first metal layer and a second metal layer arranged in sequence, a separation layer is arranged between the first metal layer and the second metal layer, and a thickness of the second metal layer is within a preset threshold range such that metal atoms of the second metal layer are capable of being thermally agglomerated and rearranged under a preset condition to form a concave-convex structure on a surface of the second metal layer.
