Display Device Movable Panel for Camera Access and Moisture Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lift-type under-screen camera technologies in mobile devices face issues with dust and water resistance due to the camera being exposed, leading to potential circuit damage and structural vulnerabilities.
Innovation Solution
A display device design that includes a frame structure, cover plate, and backplate defining a space, with a camera module and panel, where a driving assembly drives the panel to cover or expose the camera module based on mode, reducing moisture ingress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the camera is exposed outside the display device, then the camera can be accessed for photography, but moisture and dust can easily enter the device causing circuit damage
Solution Approach 1:
The patent implements a movable panel that can dynamically switch between covering and exposing the camera module. The panel is driven by a driving assembly that enables it to move between a first position (covering the camera) and a second position (exposing the camera), allowing the device to adapt its state based on operational requirements.
Solution Approach 2:
The patent applies different functional states to different regions of the display device. When the panel covers the camera, that region provides dust and water resistance; when the panel moves to expose the camera, that region transitions to provide camera accessibility. This local quality change resolves the contradiction by making the protective and accessible states mutually exclusive in time rather than space.
2Ease of operation
If the camera is exposed outside the display device, then the camera can be accessed for photography, but the device structure becomes vulnerable to damage
Solution Approach 1:
The movable panel system allows the device to maintain structural integrity by keeping the camera covered during non-operational states. The driving assembly provides controlled movement between covered and exposed states, ensuring the camera is only accessible when needed while maintaining protection during storage or non-use conditions.
Solution Approach 2:
The panel is positioned to cover the camera module in advance before any potential exposure to harmful factors. This preliminary protective action ensures the camera and internal components are protected from moisture, dust, and physical damage unless the device actively transitions to the exposed state for camera operation.
3Ease of operation
If a lift-type motor is used to lift the camera out of the middle frame structure, then the camera can be exposed, but the motor consumes a lot of power
Solution Approach 1:
The patent extracts the camera module from the middle frame structure and places it within the display device interior space. This extraction eliminates the need for lift-type motors that would be required to move the camera in and out of the frame structure, significantly reducing power consumption while maintaining camera exposure functionality.
Solution Approach 2:
The movable panel acts as an intermediary between the camera module and the external environment. Instead of moving the camera itself (which would require powerful motors), the panel moves to control access to the camera, using less energy while achieving the same functional outcome of exposing or covering the camera as needed.
4Ease of operation
If the camera is exposed outside the display device, then the camera can be accessed, but the device occupies a large structural space
Solution Approach 1:
The patent nests the camera module within the display device's internal space, specifically placing it in the space defined by the frame structure, cover plate, and backplate. This nesting arrangement eliminates the need for additional external space that would be required for exposed camera structures, reducing the overall device volume while maintaining camera functionality.
Solution Approach 2:
The patent transitions the camera from a traditional external lateral arrangement to an internal arrangement within the display device's depth dimension. By utilizing the space between the cover plate and backplate, the camera is positioned in the Z-dimension rather than requiring additional X or Y dimension space, effectively reducing the device's footprint.

AI summary
The present application provides a display device. In the display device, a frame structure, a cover plate, and a backplate define a space. A camera module, a panel, and a driving assembly are arranged in the space. The driving assembly is connected to the panel, and the driving assembly is used for driving the panel to cover the camera module. When the display device is in a non-camera mode, the panel covers the camera module. When the display device is in a camera mode, the camera module is exposed.
