Engineering Contradiction Analysis
1Area of moving object
If the display panel is bent to extend display to side surfaces, then the display area is increased, but repulsive force is generated causing lifting phenomenon between members
Solution Approach 1:
The spacer is designed with different curvatures for its upper and lower surfaces, creating local quality variations that adapt to the bending requirements at different locations. The first curvature on the upper surface and second curvature on the lower surface are specifically tailored to match the bending radius of the display panel at corresponding positions, ensuring uniform contact and stress distribution throughout the bent structure.
Solution Approach 2:
The invention changes the geometric parameters of the spacer by implementing different curvature radii on its upper and lower surfaces. This parameter modification allows the spacer to conform to the bent shape of the display panel while maintaining proper contact, thereby preventing the lifting phenomenon caused by repulsive forces in bent configurations.
2Device complexity
If the display panel is bent at a single curvature radius, then the structure is simplified, but the repulsive force causes lifting between members
Solution Approach 1:
The spacer is designed with different curvatures for its upper and lower surfaces, creating local quality variations that adapt to the bending requirements at different locations. The first curvature on the upper surface and second curvature on the lower surface are specifically tailored to match the bending radius of the display panel at corresponding positions, ensuring uniform contact and stress distribution throughout the bent structure.
3Volume of stationary object
If members are stacked closely to save space, then internal space utilization is improved, but repulsive force from bending causes lifting
Solution Approach 1:
The invention changes the geometric parameters of the spacer by implementing different curvature radii on its upper and lower surfaces. This parameter modification allows the spacer to conform to the bent shape of the display panel while maintaining proper contact, thereby preventing the lifting phenomenon caused by repulsive forces in bent configurations.

AI summary
A display device includes a display panel that is bent so that at least a portion of the display panel overlaps another portion of the display panel; and a spacer surrounded by the display panel and that includes a flat portion and a bent portion connected to the flat portion, where an upper surface of the bent portion has a first curvature and a lower surface of the bent portion has a second curvature that differs from the first curvature.
