Pop-up Camera Rail Mechanism for Notch-Free Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices with front-facing cameras suffer from a notch on the front display, limiting screen size and facing manufacturing difficulties due to complex structures in pop-up camera designs.
Innovation Solution
A pop-up camera system is integrated into the display device, featuring a camera module, rail assembly, head assembly, and motor assembly. The camera module is designed to face one side, with a rail assembly that moves up and down to protrude or retract the camera, and a motor assembly driven by electrical signals to control the camera's position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a camera is disposed on the front surface of the display device, then the camera can capture images, but a notch is generated on the front display which spoils appearance and limits display size increase
Solution Approach 1:
The camera module is nested within the display device housing, specifically positioned in a recessed area or integrated into the front case structure. The camera module can be inserted into and protruded from the display device, allowing it to be hidden when not in use and only exposed when needed, thus maintaining a clean display appearance while providing camera functionality.
Solution Approach 2:
The camera module is designed to be movable rather than fixed, capable of protruding from and retracting into the display device. This dynamic configuration allows the camera to transition between a hidden state (maintaining display appearance) and an active state (providing camera functionality), resolving the contradiction between appearance and functionality.
2Shape
If a pop-up camera is disposed inside the display device and protrudes to the outside, then the display appearance is improved, but the structure becomes complicated and manufacturing difficulty increases
Solution Approach 1:
The camera system is divided into separate functional modules: a camera module containing the imaging components, a rail assembly for movement guidance, and a motor assembly for actuation. This modular segmentation allows each component to be optimized independently and simplifies the overall assembly process, reducing manufacturing complexity while maintaining the pop-up functionality.
Solution Approach 2:
A rail assembly serves as an intermediary mechanism between the fixed camera module and the movable housing structure. The rail assembly provides a simple guided path for the camera module's movement, reducing the complexity of the protrusion mechanism compared to other possible designs while ensuring smooth and controlled motion.
3Adaptability or versatility
If a pop-up camera with complicated structure is used, then camera functionality is achieved, but assembly process problems occur due to manufacturing difficulty
Solution Approach 1:
The camera system is divided into separate functional modules: a camera module containing the imaging components, a rail assembly for movement guidance, and a motor assembly for actuation. This modular segmentation allows each component to be optimized independently and simplifies the overall assembly process, reducing manufacturing complexity while maintaining the pop-up functionality.
Solution Approach 2:
The motor assembly serves multiple functions: it provides the driving force for the camera module's protrusion and retraction, and can be integrated with the existing display device structure. This multi-functionality reduces the need for additional specialized components, simplifying manufacturing and assembly processes while achieving the desired camera functionality.

AI summary
A pop-up camera and a display device comprising same, according to one embodiment, are disclosed. The pop-up camera comprises: a camera module arranged so that the camera faces one side; a rail assembly into which the camera module is inserted, and which is formed such that the camera module can move upward and downward; a head assembly, which is open in the direction in which the camera faces and is arranged to cover the camera module and one side of the rail assembly coupled to the camera module so that the camera module and the rail assembly are maintained in a coupled state; and a motor assembly driven in response to an electrical signal to move the rail assembly upward and downward.
