Abstract

The invention relates to an OLED light-emitting unit, which is used for an OLED substrate for top light emission and comprises an anode, a cathode and an organic functional layer located between the anode and the cathode. The anode comprises a first metal layer and a second metal layer which are arranged in sequence, and an isolation layer is arranged between the first metal layer and the second metal layer. The thickness of the second metal layer is within a preset threshold range, so that metal atoms of the second metal layer can be subjected to thermal agglomeration under a preset conditionand are rearranged to form a concave-convex structure on the surface of the second metal layer. The invention further relates to an OLED display substrate and a manufacturing method of the OLED light-emitting unit.

Description

technical field

[0001] The invention relates to the technical field of manufacturing display products, in particular to an OLED light-emitting unit, an OLED substrate and a method for manufacturing the OLED light-emitting unit. Background technique

[0002] OLED (Organic Light-Emitting Diode, organic light-emitting diode) display technology has the characteristics of self-illumination, wide viewing angle, wide color gamut, high contrast, light and thin, foldable, bendable, light and portable, etc., and has become the main direction of research and development in the display field. Due to the microcavity optics, OLED devices have a certain change in color with viewing angle, and the brightness usually decreases. Now more and more people are using curved screens, and curved screens can observe the front viewing angle and the large side viewing angle of the screen at the same time, so the requirements for the viewing angle and L-decay (brightness attenuation) of the screen are ...
