Display Panel Corner Trenches for Organic Encapsulation Control

The patent divides the corner region into multiple segments by introducing trenches and grooves that partition the organic encapsulation layer into distinct sections. These segmentation structures guide the organic droplets to flow along predetermined paths, preventing uncontrolled mixing and ensuring each segment forms a regular, consistent encapsulation layer despite the extended corner geometry.

The patent introduces trenches and grooves as intermediary structures between the display elements and the organic encapsulation layer. These intermediaries act as flow channels that mediate the movement of organic droplets, directing them along controlled paths to reach their destination while maintaining formation consistency, thus resolving the conflict between extended area and manufacturing precision.

By segmenting the corner region with trenches and grooves, the patent ensures that the organic encapsulation layer forms regularly in each segment. This segmentation prevents defects that would arise from uncontrolled droplet flow, thereby maintaining reliability even as the display area is extended into corner regions.

The patent performs preliminary action by pre-defining the trench and groove structures before introducing the organic droplets. These pre-formed structures establish controlled flow paths in advance, ensuring that the encapsulation layer will form regularly regardless of the extended corner geometry, thus preserving reliability.
