Flexible Display Video Playback During Extension and Retraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with flexible displays face challenges in optimizing video playback and display adjustment based on the extension or retraction of the flexible display, limiting user interaction and customization.
Innovation Solution
An electronic device with a first and second housing, a flexible display, and a driving unit, where a processor identifies and controls the display's retracted, moving, and extended states during video playback, adjusting the displayed images accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the flexible display is extended to increase display area, then the video playback quality improves, but the device portability and compactness deteriorate
Solution Approach 1:
The flexible display transitions from a static fixed-size display to a dynamic adjustable display that can change its extended length. The display area is made variable through the driving unit that enables smooth extension and retraction, allowing the display to adapt between compact and expanded states based on usage requirements.
Solution Approach 2:
The physical parameter of the display area is changed by varying the extended length of the flexible display. The system adjusts the display area parameter dynamically through motor-driven extension and retraction mechanisms, enabling the display to transform between different size states.
2Adaptability or versatility
If the flexible display transitions between retracted and extended states, then the adaptability to different viewing needs improves, but the device complexity increases
Solution Approach 1:
The flexible display serves multiple functions by operating in different states (retracted and extended). The same display structure performs both compact storage and expanded viewing functions, eliminating the need for separate devices or components for different display size requirements.
Solution Approach 2:
The driving unit acts as an intermediary mechanism that enables the transition between retracted and extended states. This mediator component facilitates the state changes while managing the mechanical complexity, providing controlled movement without requiring complex manual operation mechanisms.
3Ease of operation
If video playback is optimized for different display states, then the user experience improves, but the control system complexity increases
Solution Approach 1:
The control system uses feedback from the display state (retracted or extended) to automatically adjust video playback parameters. The system detects the current display state and responds by optimizing video content, resolution, and playback settings accordingly, creating a closed-loop control system that enhances usability.
Solution Approach 2:
The system pre-configures different video playback settings for different display states. When a state change is detected, the appropriate video playback parameters are already prepared and immediately applied, eliminating the need for complex real-time adjustments and simplifying the control process.

AI summary
An electronic device comprises: a first housing; a second housing accommodating at least a part of the first housing, and connected to the first housing to enable sliding of the first ho using; a flexible display connected to the first housing; a driving unit for moving the first housing and the flexible display in the extension direction or the reduction direction; a memory; and a processor, wherein the memory stores instructions configured to, when executed by the processor, cause the electronic device to: identify one from among a reduced state, a moving state and an extended state of the flexible display based on a video clip playback event, and control the flexible display such that, in the reduced state, a first image included in the video clip is displayed in a display area of the reduced state, in the moving state, video is displayed in the display area of the moving state using at least a part of the video clip, and, in the extended state, a second image included in the video clip is displayed in the display area of the extended state.
