Coherent Fiber Bundle for Borderless Display Housing Concealment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with displays face challenges in minimizing display borders and creating a seamless appearance, as traditional protective cover layers can obstruct the view and fail to effectively conceal the device's housing, leading to an unsightly border around the edges of the display.
Innovation Solution
The use of a coherent fiber bundle as an image transport layer between the display and the display cover layer, which receives an image from the display, transports it to an output surface, and can be shaped to minimize borders by bending fibers outwardly, allowing the image to cover the peripheral edges of the device, thereby creating a borderless appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional protective cover layer is used, then the display is protected from damage, but the housing becomes visible around the edges of the display creating an unsightly border
Solution Approach 1:
A coherent fiber bundle is introduced as an intermediary image transport layer between the display and the protective cover layer. This fiber bundle transports the image from the display to the cover layer, allowing the image to extend beyond the display edges and conceal the housing, thereby eliminating the visible border while maintaining protection
Solution Approach 2:
The coherent fiber bundle enables image transport in a different spatial dimension by using optical fibers to convey light paths from the display to the cover layer. This allows the image to be projected onto the cover layer's outer surface, creating a borderless appearance that extends into the peripheral dimension
2Shape
If a coherent fiber bundle is used to transport the image, then the display borders are minimized, but the device structure becomes more complex
Solution Approach 1:
The coherent fiber bundle is configured as a thin, flexible image transport layer that can be integrated between the display and cover layer. The fiber bundle's flexible nature allows it to conform to the device structure while maintaining image quality, reducing the need for complex support structures
Solution Approach 2:
The coherent fiber bundle utilizes composite material structures combining multiple optical fibers bundled together with protective coatings and adhesives. This composite approach integrates multiple functions (image transport, structural support, protection) into a single component, reducing overall device complexity
3Shape
If the fiber bundle is shaped with bends to conceal the housing, then the borderless appearance is achieved, but the manufacturing precision requirements increase
Solution Approach 1:
The desired bent configuration of the coherent fiber bundle is pre-formed during the manufacturing process before assembly. By preparing the fiber bundle with its final curved shape in advance, the assembly process requires only simple integration steps, reducing the precision requirements during final device assembly
Solution Approach 2:
The manufacturing process controls fiber bundle bending by adjusting physical parameters such as temperature, pressure, and fiber coating properties during formation. These parameter changes allow precise control over the fiber configuration without requiring complex precision machining or assembly operations

AI summary
An electronic device may have a display, a display cover layer, and a sheet-packed coherent fiber bundle. The coherent fiber bundle may have an input surface that receives an image from the display and a corresponding output surface to which the image is transported. The coherent fiber bundle may be placed between the display and the display cover layer and mounted to a housing. The coherent fiber bundle may have fiber cores with bends that help conceal the housing from view and make the display appear borderless. The coherent fiber bundle has filaments formed from elongated strands of binder in which multiple fiber cores are embedded. Sheets of filaments are stacked and fused together to form the coherent fiber bundle. By aligning and fusing the sheets with respect to each other the filaments are packed with a desired density and uniformity.
