Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional protective layers and structures are added to enhance shock absorption and flexibility in foldable displays, then the reliability and adaptability improve, but the device complexity and dead space increase
Solution Approach 1:
The patent combines the shock absorption layer and anti-reflection layer into a single integrated structure. The anti-reflection layer is formed directly on the shock absorption layer, eliminating the need for separate protective structures and reducing overall device complexity while maintaining both shock absorption and anti-reflection functionalities
Solution Approach 2:
The anti-reflection layer serves multiple functions: it provides anti-reflection properties for display quality, acts as a protective layer for the shock absorption layer, and maintains structural integrity during folding. This multi-functionality reduces the need for additional dedicated protective components
2Adaptability or versatility
If the display panel is made flexible with bending regions, then the adaptability improves, but the manufacturing complexity increases
Solution Approach 1:
The display device is segmented into distinct functional regions: a first region with the shock absorption layer for flexibility and bending, and a second region without the shock absorption layer for rigid component mounting. This segmentation allows each region to be optimized for its specific function while simplifying the overall manufacturing process
Solution Approach 2:
The shock absorption layer is selectively applied only to the first region where flexibility is needed, while the second region maintains a simpler structure for component integration. This local differentiation optimizes both flexibility and manufacturability by applying complex structures only where necessary
3Area of stationary object
If the dead space is reduced by optimizing layer configuration, then the area efficiency improves, but the manufacturing precision requirements increase
Solution Approach 1:
The anti-reflection layer is formed directly on the shock absorption layer in a sequential manufacturing process, ensuring proper alignment before subsequent processing steps. This preliminary positioning of layers reduces the need for complex alignment operations later and minimizes dead space

AI summary
A display device includes a display panel having a first region, a second region, and a bending region which is between the first region and the second region and at which the display panel is bendable, an anti-reflection layer on the display panel and including a color filter, and a shock absorbing layer facing the display panel with the anti-reflection layer therebetween. The shock absorbing layer extends from the first region of the display panel and into the bending region thereof.
