Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi-display apparatuses suffer from image discontinuity due to bezel seams between adjacent display units, reducing viewer immersion.
Innovation Solution
A display apparatus and multi-display apparatus design that eliminates bezels by using a barrier pattern portion on the edge of the display portion to isolate light emitting devices, preventing water penetration and enhancing reliability, and allowing for seamless image display across multiple units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a bezel is provided to cover the bezel area at the border of the display panel, then the structural integrity and protection of the display edges are improved, but the bezel width increases and creates visible seams in multi-display apparatuses
Solution Approach 1:
The patent extracts and removes the traditional bezel structure from the display apparatus. By eliminating the bezel that covers the bezel area, the patent achieves a bezel-free display design where the display area extends to the edges of the substrate, thereby removing the source of visible seams in multi-display configurations while maintaining structural integrity through alternative edge protection methods
Solution Approach 2:
The patent merges the display area with the substrate edges by extending the display area to cover the entire front surface of the substrate. This integration eliminates the separation between display area and bezel area, creating a seamless appearance in multi-display apparatuses while maintaining structural coherence through the unified design
2Reliability
If the display area is extended to the edge of the substrate to eliminate bezels, then image continuity in multi-display apparatuses is improved, but the risk of water penetration and degradation at edge portions increases
Solution Approach 1:
The patent applies preliminary protective actions by forming a barrier pattern at the edge portions of the display area before water penetration can occur. This barrier pattern, created through specific manufacturing steps, pre-establishes a protective structure that prevents water from reaching and degrading the light-emitting devices at the edges, thereby enabling bezel-free design without compromising reliability
Solution Approach 2:
The patent introduces a barrier pattern as an intermediary structure between the external environment (water) and the light-emitting devices at the edge portions. This intermediary barrier prevents direct contact between water and sensitive components, allowing the display area to extend to the edges while maintaining protection against water penetration
3Reliability
If a barrier pattern is added to isolate light emitting devices at edge portions, then protection against water penetration is improved, but the manufacturing complexity increases
Solution Approach 1:
The patent segments the edge portion protection into a distinct barrier pattern that is separately formed and then integrated with the display structure. This segmentation allows the barrier to be manufactured using dedicated processes (such as sputtering or evaporation) and then combined with the display area, enabling protection without significantly complicating the overall manufacturing flow
