Movable Sub-Screen Camera Mechanism for Full Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile phone designs with bang or water drop screens have limited screen-to-body ratios due to the presence of a front-facing camera, which affects the display effect.
Innovation Solution
A terminal design featuring a movable first sub-screen that can change positions to expose or cover a camera located below it, allowing for a full-screen display without the need for a reserved camera area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a front-facing camera is reserved on the screen (bang screen or water drop screen), then the camera function can be implemented, but the screen-to-body ratio is reduced and the display effect is affected
Solution Approach 1:
The first sub-screen is designed to be movable rather than fixed, allowing it to dynamically change position between covering and exposing the camera. This dynamic mechanism enables the screen to adapt its configuration based on whether camera functionality is needed, thereby achieving both full-screen display effect and camera function without permanent obstruction.
Solution Approach 2:
The solution introduces movement in the vertical dimension (up and down motion) of the first sub-screen. By adding this dimensional freedom, the camera can be positioned below the screen plane when not in use, allowing the screen to achieve true full-screen coverage while the camera remains accessible when needed.
2Area of stationary object
If the first sub-screen is made movable to cover and expose the camera, then the screen-to-body ratio is increased, but the device complexity increases due to the compressible component mechanism
Solution Approach 1:
The camera is extracted from its traditional position on the screen to a location below the first sub-screen. This extraction allows the screen to achieve full coverage while the camera is separated and can be accessed independently through the movable mechanism, reducing the need for complex integrated solutions.
Solution Approach 2:
The first sub-screen is implemented as a flexible, movable component that can be displaced vertically. This flexible design allows for simpler mechanical implementation compared to rigid moving parts, enabling the screen to cover and expose the camera through straightforward up-and-down motion rather than complex mechanical assemblies.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design significantly increases the screen-to-body ratio by eliminating the need for a dedicated camera area, providing a more efficient and effective display solution while maintaining low design complexity.
Implementation Method 1
control the compressible component to be compressed by a preset height so that the first sub-screen descends to the position below the inner surface of the second sub-screen
Implementation Method 2
control the compressible component to be decompressed by the preset height so that the first sub-screen to ascend to a position aligned with the second sub-screen

AI summary
The present disclosure discloses a screen control method, a terminal, and a storage medium. The terminal includes a screen and a camera, where the screen includes a movable first sub-screen, the camera is located below the first sub-screen, and the method includes: receiving a first instruction for enabling the camera, and controlling the first sub-screen to move so that the camera changes from a first state to a second state; or receiving a second instruction for disabling the camera, and controlling the first sub-screen to move so that the camera changes from the second state to the first state, where when in the first state, the camera is covered by the first sub-screen, and when in the second state, the camera is exposed out of the first sub-screen.
