Pop-Up Camera Module Layout for Narrow-Bezel Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge of integrating a camera module into electronic devices with minimal bezel thickness is addressed by employing a pop-up camera mechanism that allows the camera to be selectively hidden behind the screen, reducing the screen bezel and enabling flexible line arrangement without interference with display panel and circuit board components.
Innovation Solution
A function module with a fixed bracket and slidable function unit is designed, where the function unit is slidably disposed on the installation surface of the fixed bracket, facing a different direction from the panel attaching surface, allowing the camera to be hidden or popped up behind the screen, and facilitating flexible cable arrangement to avoid interference with display and circuit board modules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the camera module is arranged in the front bezel to receive light via a punch-hole, then the camera can be integrated into the device, but the front bezel requires a wide portion to make space for the camera module, making it difficult to achieve an extremely thin bezel
Solution Approach 1:
The camera module is moved from the traditional front bezel plane to a rear-mounted position, utilizing the third dimension (depth) by placing the camera behind the display panel. This dimensional transition allows the camera to be integrated into the device while eliminating the need for a wide front bezel portion, thereby achieving an extremely thin bezel design.
2Volume of moving object
If the function unit is disposed on the installation surface of the fixed bracket, then the function unit can be arranged behind the screen panel, but the fixed bracket may cover or limit the outgoing line from the function unit
Solution Approach 1:
The fixed bracket is designed with asymmetric surface orientations where the installation surface and the panel attaching surface face different directions. This asymmetric design allows the function unit to be disposed on the installation surface behind the screen panel while the outgoing line can extend outward without being covered or limited by the bracket structure, thus maintaining cable arrangement flexibility.
3Ease of operation
If the outgoing line from the function unit is arranged flexibly, then the line can avoid interference with display panel and circuit board components, but the function unit structure becomes more complex
Solution Approach 1:
The fixed bracket serves multiple functions simultaneously: it provides structural support for the function unit, positions the function unit behind the screen panel, and facilitates flexible cable arrangement through its asymmetric surface design. By integrating these multiple functions into a single component, the overall device complexity is minimized while achieving the desired cable arrangement flexibility.
