Flexible OLED Panel Peeling Reduction Layer Design

The encapsulation structure is divided into multiple inorganic layers and organic layers arranged in sequence. The organic layers serve as buffer zones that can accommodate bending stresses, while the inorganic layers provide barrier functions. This segmented structure prevents peeling by distributing stress across multiple interfaces rather than concentrating it at a single layer.

Different layers are assigned different material properties and functions: inorganic layers (such as aluminum oxide) provide excellent barrier properties against moisture and oxygen, while organic layers provide flexibility and stress absorption. This local differentiation of material qualities allows the encapsulation structure to simultaneously achieve both flexibility and peeling resistance.

The encapsulation layer is constructed as a composite structure alternating between inorganic material layers and organic material layers. This composite design combines the advantages of both material types: inorganic layers provide thin-film barrier properties for flexibility, while organic layers provide strong adhesion and stress tolerance. The synergistic combination resolves the contradiction between thinness and adhesion strength.

The encapsulation structure is designed to accommodate curved bending configurations. The alternating layer structure with appropriate thickness ratios allows the encapsulation to maintain integrity when bent to small radii, effectively treating the stress distribution in a curved geometry to prevent peeling while maintaining thin overall thickness.
