Transparent Display Encapsulation Layout for Narrow Bezel Sealing

The patent divides the moisture prevention function into multiple segments: the outer dam is divided into a first outer dam and a second outer dam that are spaced apart from each other. Additionally, an inner dam is introduced to create multiple barriers. This segmentation allows the system to achieve effective moisture protection through distributed barriers rather than a single wide dam, thereby reducing the overall bezel width while maintaining protection reliability.

The patent implements a nested structure where the inner dam is positioned between the first and second outer dams, creating multiple layers of protection. The encapsulation structure nests the circuit portion within the display area, and the multiple dams create nested barriers against moisture. This nested arrangement maximizes protection efficiency within a compact space, preventing moisture from reaching the circuit portion without requiring excessive bezel width.

The outer dam is segmented into first and second outer dams spaced apart, with an inner dam positioned between them. This creates multiple narrow barriers instead of one wide barrier, achieving effective encapsulation with reduced total area. The segmentation allows moisture to be blocked at multiple points along a more compact path.

The patent utilizes the spatial dimension by positioning dams at different locations and orientations. The first and second outer dams are spaced apart in one direction, while the inner dam provides protection in another dimension. This multi-dimensional arrangement of protective barriers achieves comprehensive encapsulation without requiring a large two-dimensional bezel area.
