Engineering Contradiction Analysis
1Area of moving object
If the peripheral area is reduced to increase display area, then the display area increases, but the wiring and connection complexity increases
Solution Approach 1:
The voltage lines are divided into multiple segments (first voltage lines, second voltage lines, auxiliary voltage lines) that can be independently routed and connected. This segmentation allows the wiring to be distributed more efficiently across the reduced peripheral area, reducing overall wiring complexity while maintaining display area expansion
Solution Approach 2:
The patent introduces auxiliary voltage lines and connectors that extend into the display area, utilizing the two-dimensional space more effectively. By routing voltage lines through the display area rather than relying solely on peripheral routing, the design reduces peripheral area requirements while managing wiring complexity through spatial redistribution
2Reliability
If more voltage lines and connectors are added to maintain quality, then the display quality is maintained, but the peripheral area increases
Solution Approach 1:
The patent utilizes the display area itself as a routing dimension for voltage lines and connectors. By extending auxiliary voltage lines and connectors through the display area rather than confining all wiring to the periphery, the design maintains display quality with reduced peripheral area requirements
Solution Approach 2:
The auxiliary voltage lines and connectors serve multiple functions: they provide voltage to display elements, act as interconnection pathways, and enable flexible routing options. This multi-functionality allows the same structural elements to maintain display quality while occupying minimal peripheral space
