Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If signal lines are integrated on the panel substrate with gate and data drivers, then manufacturing cost is reduced by eliminating additional driving chips, but RC delay and noise between signal lines increase
Solution Approach 1:
The blocking member is divided into multiple segments with openings between them, creating a mesh structure that blocks electromagnetic interference while allowing signal transmission. This segmentation reduces the harmful capacitive coupling between signal lines while maintaining the shielding effect.
Solution Approach 2:
The blocking member employs a mesh structure with openings that functions as a porous shielding material. This structure allows it to block electromagnetic interference and reduce noise between signal lines while maintaining electrical signal transmission capability, effectively reducing RC delay without completely obstructing the signal paths.
2Reliability
If a blocking member is added over signal lines to reduce noise and RC delay, then signal transmission quality improves, but device complexity increases
Solution Approach 1:
The blocking member is integrated with the pixel electrode structure, combining the shielding function with the existing display element. This merging approach reduces device complexity by eliminating separate shielding components while maintaining noise reduction and RC delay mitigation benefits.
Solution Approach 2:
The blocking member serves multiple functions simultaneously: it acts as an electromagnetic shield to reduce noise between signal lines, functions as a structural support element, and maintains the electrical characteristics needed for signal transmission. This multi-functionality reduces the need for additional separate components.
