Display Panel Groove Design for Ink Flow and Stress Relief

The blocking structure is designed with a porous configuration comprising a plurality of through-holes formed in the groove. This allows the ink to penetrate through the blocking structure and reach the edge area during the inkjet printing process, eliminating the stress concentration that would otherwise occur at the blocked edge. The porous design maintains the ink containment function while enabling stress relief pathways.

The blocking structure is segmented into multiple through-holes distributed across the groove area, rather than forming a continuous solid barrier. This segmentation allows selective permeability to ink while maintaining structural integrity, enabling ink to reach specific edge regions without causing overflow in other areas.

The blocking structure transitions from a solid configuration to a porous one with multiple through-holes. This porous design reduces the continuous stress concentration at the edge by creating distributed stress pathways through the holes, while still maintaining sufficient ink containment capability through the collective effect of multiple barriers.

The through-holes in the blocking structure, which could potentially allow ink leakage, are instead utilized to enable beneficial ink flow to the edge area. This converts what would be a harmful leakage pathway into a useful channel for stress relief and ink distribution, eliminating the stress concentration problem.
