Foldable Display Device Camera Module Rear Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current foldable display devices have a limited screen-to-body ratio due to the camera module occupying a larger bezel area when fully displayed, hindering the achievement of a higher screen-to-body ratio.
Innovation Solution
A foldable display device design featuring a flexible display screen with a foldable assembly and a non-display function assembly, where the non-display function assembly is positioned away from the connector, allowing the flexible display screen to cover the support plates and connector in the unfolded state, and exposing it in the folded state, thus avoiding bezel occupation and enabling easy user operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the camera module is disposed fully on one edge of the whole display device, then the camera module can be easily installed and operated, but the bezel area is occupied and the screen-to-body ratio cannot be improved
Solution Approach 1:
The camera module is moved from the edge of the display device to the back surface, utilizing the third dimension (depth) to resolve the contradiction. This allows the camera to be positioned away from the display area, eliminating bezel occupation while maintaining accessibility for operation.
Solution Approach 2:
The display device is divided into front and back surfaces with distinct functional assignments. The display screen occupies the front surface while the camera module is positioned on the back surface, separating conflicting functional requirements into different spatial zones.
2Area of stationary object
If the flexible display screen covers the non-display function assembly in the unfolded state, then full-screen display is achieved, but the non-display function assembly is not accessible for operation
Solution Approach 1:
The device transitions between folded and unfolded states dynamically. In the unfolded state, the display screen covers the camera module for full-screen display. When folded, the camera module becomes exposed and accessible for operation, allowing the system to adapt to different operational requirements.
Solution Approach 2:
The camera module is positioned on the back surface of the device, utilizing the depth dimension to allow it to be covered by the display screen from the front while remaining accessible from the back when the device is folded.
3Area of stationary object
If the non-display function assembly is disposed on the side of the second support plate away from the connector, then the screen-to-body ratio is improved, but the assembly becomes less accessible
Solution Approach 1:
The camera module is positioned on the back surface of the device rather than on the front display surface. This spatial repositioning in the depth dimension allows the camera to be placed at the edge of the display device where it improves the screen-to-body ratio while remaining accessible from the back.

AI summary
A foldable display device includes a flexible display screen, a foldable assembly and a non-display function assembly. The states of the foldable display device include an unfolded state and a folded state. In the unfolded state, a first support plate and a second support plate are disposed on two opposite sides of a connector respectively, and the flexible display screen covers the first support plate, the connector, the second support plate and the non-display function assembly. In the folded state, a first part and a second part of the flexible display screen overlap, the first support plate and the second support plate overlap and are disposed between the first part and the second part. A part of the flexible display screen on the side of the second support plate which is away from the first support plate does not cover the non-display function assembly.
