Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display apparatuses face issues with static electricity, which can cause defects and reduce reliability, particularly in the non-display areas where electrostatic dischargers are not effectively integrated.
Innovation Solution
Incorporating electrostatic dischargers on the constant voltage line within the non-display area, positioned inside the encapsulation unit, to mitigate static electricity effects and enhance reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If electrostatic dischargers are disposed outside the encapsulation unit, then the bezel size is reduced, but the reliability is compromised and static electricity defects occur
Solution Approach 1:
The electrostatic discharger is nested inside the encapsulation unit by forming openings in the encapsulation layer, allowing the discharger to be positioned within the protected region while maintaining external functionality. This resolves the contradiction by enabling both compact bezel design and reliable static electricity protection.
Solution Approach 2:
The electrostatic discharger is positioned in a different spatial dimension by creating openings through the encapsulation unit's thickness, allowing it to be embedded within the encapsulation structure rather than being placed only on the external surface. This enables reduced bezel size while maintaining protection reliability.
2Device complexity
If electrostatic dischargers are integrated in the non-display area, then the device complexity is reduced, but static electricity defects still occur without proper encapsulation integration
Solution Approach 1:
The electrostatic discharger structure is merged with the encapsulation unit by forming openings directly in the encapsulation layer, combining two previously separate components into a single integrated structure. This reduces device complexity while ensuring reliability through proper integration.
Solution Approach 2:
The encapsulation unit serves multiple functions: it provides environmental protection and simultaneously houses the electrostatic discharger through integrated openings. This multi-functionality reduces the need for separate protective structures, simplifying the overall device while maintaining reliability.
