Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the display panel uses a uniform structure across the display area and non-display area, then the manufacturing process is simple, but the transmittance in the non-display area is reduced and folding flexibility is limited
Solution Approach 1:
The patent applies local quality by creating distinct structural regions: the display area maintains a uniform multi-layer structure for simplified manufacturing, while the non-display area incorporates grooves and reduced layer configurations to enhance transmittance and enable folding. This localized structural differentiation allows each region to optimize its properties without compromising the other.
Solution Approach 2:
The patent segments the display panel into functionally distinct zones: a display area with complete insulating and inorganic layers for device functionality, and a non-display area with grooves and selective layer removal for enhanced optical transmission and mechanical flexibility. This segmentation enables simultaneous optimization of manufacturing simplicity and transmittance performance.
2Ease of manufacture
If the display panel uses a uniform structure across the display area and non-display area, then the manufacturing process is simple, but the folding flexibility is limited
Solution Approach 1:
The patent implements local quality by providing the non-display area with grooves and selectively removed insulating and inorganic layers, creating a locally optimized structure that enhances folding flexibility. The display area retains its complete layered structure for manufacturing simplicity, while the non-display area's modified structure enables the desired adaptability for folding applications.
Solution Approach 2:
The patent segments the panel structure into a display area with full layers for manufacturing ease and a non-display area with grooves and selective layer removal for folding flexibility. This segmentation allows the device to achieve both manufacturing simplicity and adaptability by assigning different structural characteristics to different functional regions.
3Illumination intensity
If grooves are formed separately in different areas, then the transmittance and folding are improved, but the manufacturing process becomes complex
Solution Approach 1:
The patent merges the groove formation process into a single integrated etching operation that simultaneously creates grooves in both the display and non-display areas. This combined approach eliminates the need for separate etching steps, maintaining improved transmittance and folding flexibility while avoiding increased manufacturing complexity that would result from multiple discrete operations.
Solution Approach 2:
The patent employs a universal etching process that serves multiple functions: it creates grooves in the display area to improve local transmittance, creates grooves in the non-display area to enable folding, and does so through a single manufacturing step. This multi-functional approach achieves multiple performance improvements without proportionally increasing device complexity.
4Adaptability or versatility
If grooves are formed separately in different areas, then the folding flexibility is improved, but the manufacturing process becomes complex
Solution Approach 1:
The patent combines the groove formation for both display and non-display areas into a single etching operation. This merged process achieves improved folding flexibility through the non-display area grooves while avoiding the manufacturing complexity that would arise from performing separate etching operations for different regions.
Solution Approach 2:
The patent uses a universal etching process that simultaneously achieves multiple objectives: improving transmittance in the display area, enabling folding in the non-display area, and maintaining manufacturing simplicity. This multi-functional approach prevents the increase in device complexity that would result from multiple specialized etching steps.
