Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with displays face challenges in integrating displays due to shape constraints, particularly in limited spaces, where existing technologies struggle to minimize display borders and achieve desired appearances.
Innovation Solution
An image transport layer with a coherent fiber bundle or Anderson localization material is used, featuring an input surface that receives an image from the display and an output surface with different shapes, including compound curvature, to warp and transport the image effectively, while a protective layer ensures image integrity and desired appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a conventional display is integrated into an electronic device with limited space, then the display can be included in the device, but the display borders cannot be minimized and the desired appearance cannot be achieved
Solution Approach 1:
An image transport layer is introduced as an intermediary component between the display and the external environment. This layer receives images from the display and transports them to an output surface with a different shape, allowing the display to maintain its functional rectangular shape while presenting a desired aesthetic shape (e.g., circular or rounded corners) to the user, thereby minimizing visible borders and achieving the desired appearance.
Solution Approach 2:
The invention transforms the two-dimensional display image into a different two-dimensional configuration through the image transport layer. By changing the shape of the output surface while maintaining the image content, the display can fit within limited device spaces while presenting optimized visual boundaries, effectively using dimensional transformation to resolve the border minimization problem.
2Shape
If the image transport layer transforms the image shape from rectangular to circular or rounded, then the desired appearance is achieved, but the manufacturing complexity increases
Solution Approach 1:
The invention changes the physical parameters of the image transport layer, specifically its refractive index distribution and geometric configuration, to achieve image shape transformation. By carefully controlling these parameters during manufacturing, the layer can transform rectangular images into circular or rounded shapes while using established fabrication techniques, thereby managing manufacturing complexity.
Solution Approach 2:
The image transport layer may utilize composite material structures with varying refractive indices to achieve the desired image transformation. By combining different materials with complementary optical properties, the invention achieves complex shape transformation functionality while using individually manufacturable components, balancing the desired output shape with manufacturing feasibility.

AI summary
An electronic device may have a housing with a display. The display may be overlapped by an image transport layer such as a coherent fiber bundle or layer of Anderson localization material. The image transport layer may have an input surface that receives an image from the display and a corresponding output surface to which the image is transported. The input surface and output surface may have different shapes. A wristwatch device may, as an example, have a rectangular or hexagonal input surface and may have an output surface such as a rectangular output surface with rounded corners or a circular output surface. A region of the output surface may have compound curvature. A portion of the image transport layer may protrude laterally over an inactive portion of the display.
