Abstract
Provided is an encapsulation structure which is applicable for encapsulating an electroluminescent device, and includes: a first inorganic dielectric layer provided with a surface for being attached to a surface of a cathode layer of the electroluminescent device; wherein a dispersion relation among the first inorganic dielectric layer, the cathode layer and an electron injection layer of the electroluminescent device satisfies a preset condition, wherein the preset condition is configured to define an optical parameter of a first interface, the optical parameter is related to dispersion and is configured to couple surface plasmon polaritons (SPPs) on interfaces of two sides of the cathode layer, and the first interface is an interface between the first inorganic dielectric layer and the cathode layer.
