Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If display panels add various functions inside the display area, then functionality is improved, but light transmission is reduced
Solution Approach 1:
The patent moves sub-pixel circuits from the display area to the peripheral area, utilizing spatial reorganization across different dimensions. This allows the display area to maintain full light transmission while the peripheral area houses the functional circuits, effectively resolving the contradiction between adding functionality and maintaining light transmission.
Solution Approach 2:
The patent extracts sub-pixel circuits from the display area and relocates them to the peripheral area. This separation removes the obstructing elements (circuits) from the light transmission path while preserving their functional connection to the display, thereby maintaining both functionality and light transmission.
2Ease of manufacture
If sub-pixel circuits are located at the first display area, then electrical connection is simplified, but display area is reduced
Solution Approach 1:
The patent relocates sub-pixel circuits to the peripheral area, utilizing the unused space in the peripheral region. This spatial reorganization increases the display area while maintaining electrical connections through conductive bus lines that extend from the peripheral area to the display area.
Solution Approach 2:
The patent divides the display panel into distinct functional zones: the display area for light emission and the peripheral area for housing sub-pixel circuits. This segmentation allows each area to be optimized for its specific function, maximizing display area while maintaining circuit functionality.
3Illumination intensity
If conductive bus lines are made of light-transmissive material, then light transmission is improved, but manufacturing complexity increases
Solution Approach 1:
The conductive bus lines serve dual functions: electrical connection and light transmission. By selecting materials that possess both conductive and transparent properties, the same structural element fulfills multiple roles, avoiding the need for separate components and thereby reducing overall manufacturing complexity despite the specialized material requirements.
