Flexible Display Screen Capture With Position-Matched Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable electronic devices with flexible displays face challenges in efficiently capturing and replaying visual content across varying display configurations, particularly when the display is extended, retracted, or rolled onto different device sides, as conventional methods fail to account for the dynamic changes in display size and orientation.
Innovation Solution
An electronic device with a flexible display support structure that moves between retracted and extended positions, equipped with a translation mechanism, position sensor, and controller, enables screen capture and playback by recording frames with position data, allowing flexible display content to be presented and recorded on both front and back sides, and adjusting display dimensions based on sensor data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a flexible display is used that can extend and retract, then the display area and versatility are improved, but the complexity of capturing and replaying visual content increases due to varying display configurations
Solution Approach 1:
The system captures position data of the flexible display support structure at the moment of screen capture. This preliminary recording of positional information enables the replay function to restore the display to its exact previous configuration, solving the complexity issue by pre-storing the necessary restoration data.
Solution Approach 2:
The system uses a position sensor to continuously monitor and provide feedback on the position of the flexible display support structure. This feedback mechanism allows the controller to accurately track display configuration changes and coordinate the replay function to match the captured state, reducing system complexity through automated position-based control.
2Area of moving object
If the flexible display support structure moves between retracted and extended positions, then the display area changes, but maintaining consistent visual content capture and playback across positions becomes difficult
Solution Approach 1:
The system records not only the visual content but also the precise position data of the flexible display support structure at the time of capture. This preliminary storage of positional information ensures that during playback, the display can be restored to the exact same configuration, guaranteeing consistent visual content presentation regardless of subsequent position changes.
Solution Approach 2:
The position sensor provides continuous feedback on the display support structure's position, enabling the controller to dynamically adjust the captured content display to match the current configuration. This feedback loop ensures that visual content remains consistent and properly positioned across all display configurations.
3Loss of information
If screen capture is performed on a flexible display, then visual content can be recorded, but replaying the captured content requires the display to be in the same position, which reduces operational flexibility
Solution Approach 1:
The system pre-records the position data of the flexible display support structure alongside the visual content during capture. This preliminary storage of positional metadata enables the replay function to automatically restore the display to the correct position, eliminating the constraint that the display must remain in the same position for playback and thus preserving operational flexibility.

AI summary
An electronic device, method, and computer program product enable screen capture and playback of an extendable display provided by a flexible display coupled across a front side of a flexible display support structure that moves relative to a first housing. A remaining portion of the flexible display either scrolls up or rolls onto a backside of the base housing. A controller of the electronic device determines dimensions of a front display based on data from a position sensor. The controller presents visual content on the flexible display. In response to a trigger to screen record the visual content, the controller records in media file(s) frame(s) of the front display along with position data of the flexible display support structure. For playback, the controller activates the translation mechanism to match the position data and presents the frame(s) on corresponding portions of the flexible display from which the frame(s) was captured.
