Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If transistors and voltage supply lines are arranged in the display area to control brightness and light emission, then display functionality is achieved, but image quality deteriorates due to interference
Solution Approach 1:
The patent extracts voltage supply lines from the display area by introducing bridge lines that connect data lines across the transmissive area boundary. This allows voltage supply lines to be routed through the non-display area while maintaining electrical connectivity to transistors in the display area, thereby eliminating interference with the display area while preserving display functionality.
2Adaptability or versatility
If data lines are split into first and second parts separated by transmissive area, then layout flexibility is improved, but electrical connectivity becomes difficult to maintain
Solution Approach 1:
The patent introduces bridge lines as intermediary conductive structures that span the transmissive area to connect the first and second parts of data lines. These bridge lines act as mediators that maintain electrical connectivity across the gap created by the transmissive area separation, enabling both layout flexibility and reliable electrical connectivity simultaneously.
3Reliability
If bridge lines and horizontal conductive lines are added to improve connectivity, then voltage distribution is enhanced, but device complexity increases
Solution Approach 1:
The patent merges multiple functions into the bridge line structure. The bridge lines serve both as connectors for data lines and as pathways for voltage supply, while horizontal conductive lines integrated with the bridge lines provide additional voltage distribution paths. This consolidation of functions reduces the need for separate dedicated structures, thereby enhancing voltage distribution without proportionally increasing device complexity.
