Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If various elements are arranged in the display area to add functions, then functionality is improved, but reliability deteriorates due to increased complexity and potential failure points
Solution Approach 1:
The patent divides the display area into distinct functional zones: a transmission area for additional functions and a display area for visual output. This segmentation allows independent optimization of each zone, enabling additional functionality without compromising the reliability of the display function itself.
Solution Approach 2:
The patent introduces a non-display area as an intermediary zone between the transmission area and the display area. This intermediary region houses conductive patterns and wiring, isolating potential failure points from both the transmission and display functions, thereby maintaining overall system reliability while enabling enhanced functionality.
2Illumination intensity
If a transmission area is created within the display area, then light transmission is improved, but device complexity increases due to additional conductive patterns and wiring
Solution Approach 1:
The patent resolves wiring complexity by transitioning to a three-dimensional layered structure. Conductive patterns are distributed across multiple layers (first conductive pattern layer, second conductive pattern layer, third conductive pattern layer), with vertical connections through contact holes. This dimensional organization manages complexity by separating horizontal and vertical routing paths.
Solution Approach 2:
The patent implements nested conductive pattern structures where multiple conductive layers are stacked within the display device thickness. The first, second, and third conductive pattern layers are nested vertically, with each layer serving specific routing functions. This nesting consolidates multiple wiring functions into a compact vertical arrangement, managing complexity through hierarchical organization.
3Adaptability or versatility
If conductive patterns are added in the non-display area to support transmission area functionality, then functionality is improved, but the risk of electrostatic discharge increases
Solution Approach 1:
The patent converts the potential harm of electrostatic discharge into a beneficial protective mechanism by implementing dedicated electrostatic discharge protection circuits in the non-display area. These protection circuits are strategically positioned to intercept and safely dissipate static charges before they can reach sensitive functional areas, transforming the hazard into a protective feature.
