Engineering Contradiction Analysis
1Reliability
If peripheral circuit region is arranged in conventional manner, then functional circuits can be provided, but reliability is reduced due to flexible display process challenges
Solution Approach 1:
The display panel is divided into a display region and a non-display region, with the non-display region containing peripheral circuits and binding pins. This segmentation isolates the flexible display process challenges from the functional circuit requirements, improving reliability by allowing independent optimization of each region.
Solution Approach 2:
The patent introduces a third connecting line with connecting sub-lines that extend in different directions and layers to connect signal lines in the display region to binding pins in the non-display region. This multi-dimensional routing approach provides alternative paths for signal transmission, enhancing reliability by avoiding single-point failures in the peripheral circuit arrangement.
2Area of stationary object
If border width is reduced, then screen-to-body ratio is improved, but signal transmission reliability may be compromised
Solution Approach 1:
The connection path is segmented into multiple independent segments: first connecting lines from display region to third connecting line, second connecting lines from third connecting line to binding pins, and third connecting lines as bridge connections. This segmentation allows the signal transmission path to be distributed across multiple routes, maintaining reliability even when border width is reduced.
Solution Approach 2:
The third connecting line acts as an intermediary structure that bridges the display region and non-display region. It provides a stable transmission path through its connecting sub-lines that extend in different directions, ensuring signal transmission reliability while enabling reduced border width design.
3Reliability
If multiple connecting lines are used, then signal transmission is improved, but manufacturing complexity increases
Solution Approach 1:
The third connecting line serves multiple functions: it connects first connecting lines from the display region, provides connection paths to binding pins, and acts as a structural bridge between regions. This multi-functionality reduces the need for separate dedicated connection structures, simplifying manufacturing while maintaining improved signal transmission.
