Foldable Display Camera Layout for Wide-Angle Imaging
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 fisheye lenses.
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 Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a camera with a fisheye lens is mounted to increase the angle of view, then the angle of view is improved, but a protrusion is formed in the electronic device or the housing becomes large
Solution Approach 1:
The imaging unit is nested within the display unit, with the imaging sensor positioned behind the display panel. This allows the camera to be integrated into the housing without creating external protrusions, as the imaging components are contained within the existing display unit volume.
Solution Approach 2:
The imaging unit captures images through the display panel from the rear side, utilizing the depth dimension of the housing rather than expanding the external footprint. This enables a wide angle of view without increasing the housing's external dimensions.
2Adaptability or versatility
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 becomes large

3Adaptability or versatility
If a camera having a large angle of view is mounted in a housing, then the angle of view is improved, but an adjacent component is included in a captured image
Solution Approach 1:
A light shielding layer is provided at specific locations within the housing to block light from adjacent components from reaching the imaging sensor. This selective shielding maintains the wide angle of view while preventing unwanted adjacent components from appearing in the captured images.
Solution Approach 2:
A light shielding layer is introduced as an intermediary element between the imaging unit and adjacent components. This shielding layer selectively blocks light paths from adjacent components to the imaging sensor, preventing them from appearing in captured images while preserving the wide angle of view capability.
