Foldable Display Camera Layout for Bezel-Free Selfie Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with larger screens face portability issues due to low screen-to-body ratios, making them bulky and difficult to carry, and the integration of front-facing cameras limits the achievement of a bezel-less design.
Innovation Solution
The electronic device incorporates a foldable display with a folding rotating shaft and a rear-mounted camera that functions as both front- and rear-facing, allowing for a high screen-to-body ratio and bezel-less design by eliminating the need for a front-facing camera.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a front-facing camera is disposed on the front of the display, then the selfie function is supported, but the screen-to-body ratio is reduced due to the need for a bezel or camera cutout
Solution Approach 1:
The camera is designed to serve dual purposes: it functions as a rear-facing camera when the display is in the first state (unfolded), and as a front-facing camera when the display is in the second state (folded). This multi-functionality eliminates the need for separate front and rear cameras, thereby maximizing the screen-to-body ratio while maintaining both selfie and regular photography capabilities.
Solution Approach 2:
The camera's functional role dynamically changes based on the display's state. When the display transitions between unfolded and folded states, the camera automatically switches between serving as a rear-facing camera and a front-facing camera. This dynamic adaptation allows the system to maintain optimal screen-to-body ratio across different usage scenarios.
2Area of stationary object
If the display is made large to provide better user experience, then the screen area is increased, but the device becomes bulky and less portable
Solution Approach 1:
The display is divided into two separable display panels that can be folded relative to each other. This segmentation allows the large screen area to be achieved while enabling the device to be folded into a compact form factor for portability. The folding mechanism creates two distinct sections that can be collapsed together, reducing the overall device volume when not in use.
Solution Approach 2:
The display utilizes a third dimension (folding depth) to resolve the contradiction between screen area and portability. By folding the display along a hinge axis, the large screen can be collapsed into a compact configuration, effectively using vertical space to reduce the device's horizontal footprint and improve portability while maintaining the large screen area when unfolded.

AI summary
This application provides an electronic device. The electronic device includes a foldable display, a folding rotating shaft, and at least one camera. The display includes a first display subarea and a second display subarea. The folding rotating shaft is configured to fold or unfold the first display subarea and the second display subarea. The at least one camera is disposed on the rear of the first display subarea. When the first display subarea and the second display subarea are in a folded state, the rear of the first display subarea is opposite to the rear of the second display subarea, and the at least one camera is used as a front-facing camera in the second display subarea. Therefore, the electronic device in the embodiments of this application can support a selfie function, and may also have a relatively high screen-to-body ratio.
