Foldable Display Camera Layout for Wide-Angle Compact Housings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices face challenges in achieving a wide angle of view without increasing the device size or including adjacent components in the captured image, particularly when using a fisheye lens.
Innovation Solution
Incorporating a deformable display unit with imaging units on opposite sides, allowing for flexible folding and switching optical systems to adjust the angle of view based on the display's shape, and using a processing circuit to manage image capture and display.

Engineering Contradiction Analysis
1Length of moving object
If a camera with a fisheye lens is mounted to increase the angle of view, then the angle of view is improved, but the housing size increases or a protrusion is formed
Solution Approach 1:
The imaging unit is positioned behind the display panel, utilizing the thickness dimension of the housing rather than extending outward. This allows the camera to capture wide-angle images without increasing the housing's external dimensions or creating protrusions, as the imaging path is routed through the display panel's depth.
Solution Approach 2:
The imaging unit is nested within the housing by positioning it behind the display panel, effectively hiding the camera mechanism inside the existing housing volume. This nesting approach allows the fisheye lens to be accommodated without increasing the overall housing size or creating external protrusions.
2Length of moving object
If a camera with a large angle of view is mounted in a housing, then the angle of view is improved, but adjacent components are included in the captured image
Solution Approach 1:
Adjacent components that would interfere with the wide-angle capture are excluded from the imaging path by positioning the imaging unit behind the display panel. The display panel acts as a barrier that blocks light from adjacent components while allowing light from the intended scene to reach the imaging unit, effectively extracting the problematic elements from the optical path.
3Volume of moving object
If the display unit is made deformable to enable folding, then the housing compactness is improved, but the structural complexity increases
Solution Approach 1:
The display panel is designed to be flexible and deformable, allowing the housing to transition between folded and unfolded states. This dynamic structure enables the housing to compact into a smaller form factor while maintaining the necessary structural integrity for housing the imaging unit and other components.
