Movable Camera and Secondary Screen Assembly for Full-Screen Mobile Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing all-screen mobile phone designs leave unused space due to camera placement, which hinders a seamless visual experience and user interaction.
Innovation Solution
A display screen assembly with a primary screen, a transparent area, and a driving component that alternately positions a camera and a secondary screen to face the transparent area, allowing the camera to be hidden beneath the screen after picture-taking, enabling full-screen display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the camera is placed on the primary screen to enable picture-taking function, then the camera can be easily accessed, but the screen area is reduced and visual obstructions occur
Solution Approach 1:
The camera is made movable rather than fixed, allowing it to dynamically change position between facing the transparent area for picture-taking and facing away to clear the screen. The driving component enables the camera to rotate or translate, transforming it from a static obstruction into a dynamic element that only occupies screen space when needed.
Solution Approach 2:
The camera is moved from the two-dimensional screen plane into the third dimension by positioning it on the side of the primary screen away from the light exit face. This allows the camera to be stored in a space that does not interfere with the screen's visual area, and only intrude when actively taking pictures.
2Area of stationary object
If the camera is placed on the side of the primary screen away from the light exit face to clear the display area, then the screen area is maximized, but the camera cannot directly face the transparent area for picture-taking
Solution Approach 1:
The camera assembly is made dynamically reconfigurable through the driving component, which enables it to rotate or translate and face the transparent area when picture-taking is needed. This dynamic capability restores the camera's orientational versatility while allowing it to remain in a non-intrusive position during normal display operation.
Solution Approach 2:
The camera periodically changes its orientation state - facing away from the transparent area during normal display time and facing toward it during picture-taking. This periodic repositioning allows the system to alternatingly prioritize screen area and camera functionality without permanent compromise of either.
3Area of stationary object
If a driving component is added to enable the camera to move and face the transparent area, then the camera can be hidden below the screen for full display, but the device structure becomes more complex
Solution Approach 1:
The driving component is integrated with the existing camera module and secondary screen assembly. The same driving mechanism serves multiple functions: positioning the camera, managing the secondary screen, and coordinating with the transparent area. This merging approach minimizes additional complexity while achieving the full-display effect.
Solution Approach 2:
The driving component is designed as a multi-functional element that not only positions the camera but also manages the secondary screen and coordinates with the transparent area. By making the driving component universal, the patent reduces the need for separate mechanisms for each function, thereby limiting the increase in overall device complexity.

AI summary
The disclosure relates to the field of electronic devices, and discloses a display screen assembly and a mobile terminal, and the display screen assembly includes a primary screen, wherein the primary screen includes a transparent area, and a driving component, a camera, and a secondary screen arranged on a side of the primary screen away from a light exit face, wherein the driving component is configured to drive the camera and the secondary screen to be alternately arranged facing the transparent area. In the display screen assembly, the driving component drives the camera to face the transparent area to thereby take a picture, and drives the secondary screen to face the transparent area after the picture is taken, so that the camera is hidden below the primary screen.
