Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If wires are arranged in a straight line through the opening peripheral region, then the wire layout is simple, but the display area is reduced and camera integration is hindered
Solution Approach 1:
The patent applies curvature by bending the wires in an S-shape within the opening peripheral region. This curved wire arrangement allows the wires to pass through the limited space of the opening peripheral region without requiring additional space that would reduce the display area, while still maintaining proper electrical connections and enabling camera integration.
Solution Approach 2:
The patent utilizes the vertical dimension by forming capacitors between the bent wires and the semiconductor pattern/conductive pattern in the opening peripheral region. This three-dimensional capacitor structure allows for load compensation without occupying additional planar space, thus preserving the display area while managing wire complexity.
2Area of stationary object
If wires are bent to pass through the opening peripheral region, then space utilization is optimized, but manufacturing precision requirements increase
Solution Approach 1:
The patent incorporates the wire bending and capacitor formation into the existing manufacturing process flow. The wires are patterned with predetermined bends during the standard wire formation process, and capacitors are formed simultaneously with other device structures. This preliminary planning of wire paths and integrated capacitor formation reduces the need for additional precision steps.
Solution Approach 2:
The patent combines multiple functions into the opening peripheral region: wires are bent to pass through this region while simultaneously forming capacitors between the wires and the semiconductor/conductive patterns. This merging of wire routing and capacitor formation into a single integrated structure simplifies the overall manufacturing process and reduces the cumulative precision requirements of separate steps.
3Reliability
If wires are arranged to form capacitors in the opening peripheral region, then load compensation is sufficient, but the device structure becomes more complex
Solution Approach 1:
The opening peripheral region serves multiple functions: it provides a pathway for wires to connect display regions, contains bent wire sections that form capacitors for load compensation, and enables camera integration. By making this region multi-functional, the patent achieves reliable load compensation without adding separate dedicated structures, thus avoiding increased device complexity.
Solution Approach 2:
The wires serve themselves by forming capacitors with the semiconductor pattern and conductive pattern in the opening peripheral region. The bent portions of the wires automatically create the capacitor structure through their proximity to these patterns, eliminating the need for separate capacitor formation steps or additional components. This self-service approach provides reliable load compensation while maintaining structural simplicity.
