Abstract

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.
