Flexible Display Screen Pivot Design for Hidden Camera Holes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional under-screen camera devices face issues with color inconsistency and resolution due to the camera hole's impact on the display region, necessitating a solution that enhances the display effect by hiding the camera hole when not in use.
Innovation Solution
A display device design featuring pivot shafts and a telescopic mechanism that rotates the flexible display screen to position the camera hole opposite the lens when active and winds it around the shaft when inactive, ensuring a full-screen display and minimizing color differences and resolution inconsistencies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a camera hole is defined in the flexible display screen for under-screen camera device, then the camera can capture images, but the display region is reduced and color inconsistency occurs
Solution Approach 1:
The flexible display screen is designed to be dynamically reconfigurable between flat and wound states. When the camera is active, the screen remains flat to allow camera access; when the camera is inactive, the screen winds around the pivot shaft to cover the camera hole, maximizing display area and eliminating color inconsistency.
Solution Approach 2:
The display screen is functionally segmented into regions that can be independently configured. The camera hole region can be isolated and covered by winding the screen, separating the camera function from the display function spatially when needed, thus preserving display quality while maintaining camera capability.
2Adaptability or versatility
If a camera hole is defined in the flexible display screen, then the camera device can be integrated, but color difference and resolution inconsistency occur
Solution Approach 1:
The camera hole is extracted as a separate functional element from the continuous display surface. By winding the flexible screen, the camera hole region is physically removed from the visible display area, eliminating its negative impact on display uniformity while preserving camera functionality when needed.
3Area of stationary object
If the flexible display screen is wound around the pivot shaft when camera is off, then full-screen display effect is achieved, but device complexity increases
Solution Approach 1:
The flexible display screen serves multiple functions: it acts as both the display surface and the cover for the camera hole. The same screen material and structure enable both full-screen display mode (when wound) and camera access mode (when flat), eliminating the need for separate cover components and reducing overall device complexity.

AI summary
The present application relates to a display device that connects two side edges of a flexible display screen to two pivot shafts respectively. When a camera device is turned on, a camera hole and a lens are disposed oppositely. When the camera device is turned off, a portion of a flexible display screen defined with a camera hole is wound around one of the pivot shafts, under a non-photography state of the camera device, the camera hole hidden in a frame body, and the exposed flexible display screen presents a full screen display effect to improve user experience.
