Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If a flexible display panel with multiple display portions is used to enlarge display area, then the display area is increased, but the device thickness increases
Solution Approach 1:
The display panel is folded back and nested within the housing space, with the first display portion on the front surface and additional display portions on side surfaces, creating a compact multi-surface display configuration that enlarges total display area without proportionally increasing device thickness
Solution Approach 2:
The display extends from a single front surface to multiple surfaces including side surfaces of the housing, transitioning from two-dimensional to three-dimensional display arrangement, thereby enlarging display area while maintaining compact thickness through spatial optimization
2Area of moving object
If multiple display portions are integrated into a single flexible panel, then the display area is enlarged, but the device complexity increases
Solution Approach 1:
Multiple display portions are integrated into a single flexible display panel with continuous seamless display across different surfaces, combining what would traditionally be separate display units into one unified structure, thereby enlarging display area while managing complexity through integration
Solution Approach 2:
The flexible display panel serves multiple functions: displaying images on front and side surfaces, folding back to utilize housing space, and providing continuous seamless display across different orientations, thereby enlarging display area while justifying the structural complexity through multi-functionality
3Volume of stationary object
If the display panel is folded back to utilize housing space, then the housing space utilization is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The display panel is pre-configured with specific folding characteristics and attachment points during manufacturing, allowing it to be folded back along predetermined paths to optimal positions within the housing, thereby improving housing space utilization while managing manufacturing precision through pre-planned folding geometry

AI summary
A display device or an electronic device in which the number of components can be reduced can be provided. An electronic device in which a space in a housing can be effectively used can be provided. A display panel includes a first display portion positioned on the front surface of the housing, a second display portion and a third display portion that are provided along adjacent two of the side surfaces of the housing, and a first portion that is folded back to the rear side of the first display portion. When the display panel is developed, the first portion faces the first display portion with the second display portion provided therebetween. The first portion includes an external connection terminal or a driver circuit.
