Innovation Solution
A flexible circuit board with geodesic faceting that integrates a plurality of rigid sensor and display facets, forming a continuous sensing and display surface, enabling accurate light field capture and display through microlens arrays and in-layer signal processing, allowing for unidirectional emulated transparency and high-resolution, lightweight, and comfortable light field reproduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a flexible circuit board with gaps between facet locations is used, then the board can be formed into a three-dimensional shape, but the gaps prevent continuous sensing and display surfaces
Solution Approach 1:
The circuit board is divided into multiple rigid facets separated by flexible gaps, allowing each facet to maintain structural integrity while the gaps provide flexibility for forming three-dimensional shapes
Solution Approach 2:
The gaps between rigid facets are designed to be flexible and adaptable, allowing the board to dynamically change from a flat configuration with visible gaps to a three-dimensional configuration where gaps are substantially eliminated and continuous surfaces are formed
2Measurement precision
If multiple separate micro displays are assembled on a flexible circuit board, then high-resolution light field reproduction is achieved, but device complexity increases
Solution Approach 1:
Multiple separate micro displays are assembled on a single flexible circuit board to form a unified multi-facet display system, combining the advantages of high-resolution individual displays with the flexibility of a single integrated structure
Solution Approach 2:
The flexible circuit board serves multiple functions: it provides structural support for multiple micro displays, enables three-dimensional configuration, allows for continuous surface formation, and facilitates light field reproduction across multiple facets
3Measurement precision
If traditional electronic displays are used, then they can capture and display light fields, but they are bulky and uncomfortable for users
Solution Approach 1:
The display system uses a flexible circuit board with thin rigid facets instead of traditional bulky rigid structures, significantly reducing weight and improving comfort for wearable applications while maintaining light field capture and display capabilities

AI summary
In one embodiment, a flexible circuit board includes: a plurality of facet locations that each correspond to a particular one of a plurality of rigid sensor facets and a particular one of a plurality of rigid display facets. The flexible circuit board also includes a plurality of wire traces that serially connect the plurality of facet locations, The facet locations are arranged into a plurality of facet coIumns. When the flexible circuit board is flat, at least some of the facet locations are separated from one or more adjacent facet locations by a plurality cf gaps, When the flexible circuit board is formed, into a three-dimensional shape, the plurality of gaps are substantially eliminated, thereby permitting the plurality of rigid sensor facets to form a continuous sensing surface and the plurality of rigid display facets to form a continuous display surface.
