AI Technical Summary

Technical Problem

Existing optoelectronic devices have shortcomings in light extraction efficiency and viewing angle characteristics, and the anti-reflective coating has low mechanical strength and is easily damaged by physical forces.

Method used

Multiple pores are formed on the charge carrier functional layer, and anti-reflective material is partially filled into the pores to form an anti-reflective part and an anti-reflective layer, thereby improving adhesion and increasing mechanical stress.

Benefits of technology

By enhancing the contact between the antireflective material and the charge carrier functional layer, the mechanical strength of the optoelectronic device is improved, the risk of antireflective material detachment or damage is reduced, and the light extraction efficiency and viewing angle characteristics are enhanced.

Abstract

This application discloses an optoelectronic device, its fabrication method, and a display device. The optoelectronic device includes a bottom electrode, a charge carrier functional layer, and a top electrode stacked together. The optoelectronic device also includes an anti-reflective material disposed between the charge carrier functional layer and the top electrode. The charge carrier functional layer has multiple pores on the side facing the top electrode, and at least a portion of the anti-reflective material fills at least one of the pores. This effectively improves the adhesion of the anti-reflective material, increases the mechanical stress of the optoelectronic device, and helps reduce the risk of the anti-reflective material detaching or being damaged.
