摘要： A display, lighting, window, or signage product incorporates a panel including a collection of distinct electro-optical elements formed over a substrate. The substrate is in the form of a matrix with multiple openings that are filled with respective rigid local encapsulation seals. A second set of rigid local encapsulation seals are adhered over the electro-optical elements, so that each electro-optical element has a local seal below it, and another local seal above it. The electro-optical elements may be light-emissive, light-controlling, and/or light-sensing.

摘要： An electroluminescent display or lighting product incorporates a panel comprising a collection of distinct light-emitting elements formed on a substrate. A plurality of distinct local seals are formed over respective individual light-emitting elements or groups of light-emitting elements. Each local seal is formed by depositing a low melting temperature glass powder suspension or paste, and fusing the glass powder. Fusing may be performed using selective heating by microwave or laser irradiation. Energy absorption may be enhanced by incorporating absorbing particles in the glass powder paste or suspension. The local seal may be used in conjunction with a continuous thin film encapsulation structure. Optical functions can be provided by each local seal, including refraction, filtering, color shifting, and scattering.

摘要： An electroluminescent display or lighting product incorporates a panel comprising a collection of distinct light-emitting elements formed on a substrate. A plurality of distinct local seals are formed below respective individual light-emitting elements or groups of light-emitting elements. Some embodiments combine a metal foil substrate and glass local seals in a flexible bottom-emitting product. The local seal may be used in conjunction with a continuous thin film encapsulation structure. Optical functions can be provided by each local seal, including refraction, filtering, color shifting, and scattering. Each local seal is formed by depositing a low melting temperature glass powder suspension or paste using inkjet technology, and fusing the glass powder using a scanning laser beam having a tailored beam profile. In other embodiments, a lower encapsulation substrate incorporating local window seals is wholly or partially pre-formed.

摘要： An electro-optical panel product comprises a collection of distinct light-emitting elements formed on a substrate. The product may be a display or lighting apparatus, and each electro-optical element may be an OLED. Distinct local seals are formed below respective individual electro-optical elements or groups of electro-optical elements. Some embodiments combine a metal foil substrate and glass local seals in a flexible bottom-emitting product. The local seal may be used in conjunction with a continuous thin film encapsulation structure. Optical functions can be provided by each local seal, including refraction, filtering, color shifting, and scattering. Each local seal is formed by depositing a low melting temperature glass powder suspension or paste using inkjet technology in openings formed in a starter substrate; the glass powder is fused using a scanning laser beam having a tailored beam profile. The lower encapsulation substrate incorporating local window seals may be wholly or partially pre-formed.
