1. A panel product incorporating an active region comprising:
a) a flexible encapsulating substrate comprising:
i) a flexible matrix having a plurality of openings, each having a respective area;
ii) a thin film encapsulation layer, wherein the thin film encapsulation layer is flexible and light-transmissive;
iii) a plurality of separate local encapsulation seals, wherein each local encapsulation seal is rigid, light-transmissive, occupies an area that substantially includes the area of at least one opening in the flexible matrix, and is separated from the matrix by a portion of the thin film encapsulating layer;
b) a two-dimensional array of electro-optical elements formed over the flexible encapsulating substrate in the active region, wherein first and second neighboring electro-optical elements are located directly above different local encapsulation seals; and
c) a flexible upper encapsulation structure.
