The implementation of a flexible display electronic device that can be physically deformed by bends, with processors reconfiguring content aspect ratios and repurposing display portions to present secondary content, reducing processor operational loads and power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the device uses a fixed processor configuration for content presentation, then the processor can handle complex content rendering, but the device cannot adapt to different aspect ratios and environments efficiently
Solution Approach 1:
The patent implements dynamic processor configuration where the system automatically adjusts processor operational modes and resource allocation based on detected aspect ratio changes. The processor transitions between different operational states (full resolution rendering, scaled rendering, selective rendering) depending on whether the display is in 16:9, 4:3, or other aspect ratios, enabling adaptability without requiring manual reconfiguration or complex hardware changes.
Solution Approach 2:
The system changes processor rendering parameters dynamically based on aspect ratio detection. When the aspect ratio changes from 16:9 to 4:3 or other ratios, the processor adjusts its rendering parameters including resolution scaling, content selection priorities, and power management settings. This parameter-based adaptation allows the same processor hardware to efficiently handle different display configurations without physical reconfiguration.
2Use of energy by moving object
If the processor renders content for the entire flexible display, then full content coverage is achieved, but processor workload and power consumption increase
Solution Approach 1:
The patent segments the flexible display into multiple zones or regions when the aspect ratio changes. Instead of rendering content across the entire display area, the system divides the display into active content regions and inactive or secondary regions. The processor focuses rendering resources on the primary content area while reducing or eliminating rendering in secondary areas, thereby reducing power consumption while maintaining essential content presentation.
Solution Approach 2:
The system applies partial rendering action by selectively rendering only the necessary portions of content based on the current aspect ratio. When the flexible display is bent to a non-16:9 aspect ratio, the processor renders content at full quality for the primary viewing area while using scaled, reduced, or omitted rendering for areas that would otherwise require excessive processing power, achieving energy efficiency without completely sacrificing content completeness.
3Adaptability or versatility
If the device maintains a single aspect ratio configuration, then content presentation is optimized for that ratio, but the device cannot function effectively in various modes and environments
Solution Approach 1:
The patent implements dynamic aspect ratio adaptation where the device automatically detects and responds to changes in display geometry. The system monitors the flexible display's physical state and dynamically adjusts content rendering parameters, processor allocation, and power management settings to match the current aspect ratio. This enables the device to function effectively across multiple operational modes (folded, unfolded, partially folded) while maintaining content rendering efficiency through automated parameter adjustment.
Solution Approach 2:
The system achieves multi-functionality by designing the content rendering system to handle multiple aspect ratios using the same hardware infrastructure. The processor is configured to universally support 16:9, 4:3, and other aspect ratios through software-based rendering adjustments rather than requiring dedicated rendering pipelines for each ratio. This universal approach enables operational versatility across different device configurations while maintaining rendering efficiency through a single, adaptable code path.

AI summary
An electronic device includes a housing, which may be deformable or may include hinges to allow a display, which is flexible, to be deform by bending or other operations. One or more flex sensors detect when the electronic device is deformed at a deformation portion. One or more processors, which include an application processor, reconfigure a presentation of content along the flexible display in response to detecting deformation at the deformation portion, where the reconfiguring includes a content aspect ratio transition from a first predefined aspect ratio to a second predefined aspect ratio.
