Sliding Flexible Display Layout and Audio Sync During Retraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with slidable form factors face issues of reduced content visibility and usability when transitioning from a slide-out to a slide-in state due to changes in display area size and aspect ratio, leading to potential marginal areas and decreased immersion.
Innovation Solution
An electronic device with a flexible display and bendable section, controlled by a processor, adjusts the display and audio output based on the state of the bendable section's retraction or extension, ensuring important content is displayed without marginal areas and synchronized audio output.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the flexible display is retracted into the housing (slide-in state), then the electronic device size is reduced for portability, but the display area decreases and content visibility deteriorates
Solution Approach 1:
The patent implements a dynamic display area that automatically adjusts based on the slideable section's position. The processor detects the retraction/extension state and dynamically modifies the displayed content area and aspect ratio to match the currently visible display portion, ensuring optimal content presentation in both compact and expanded states.
Solution Approach 2:
The system changes display parameters (content area size, aspect ratio, marginal area configuration) based on the physical state of the slideable section. When retracted, the display parameters are adjusted to fit the smaller visible area; when extended, parameters are modified to utilize the larger display surface, thereby resolving the contradiction between device compactness and display area.
2Area of stationary object
If the content size is reduced to fit the slide-in state display area, then the content can be displayed, but the content visibility and immersion deteriorate
Solution Approach 1:
The patent dynamically adjusts the content display area and aspect ratio based on the slideable section's position. Rather than simply reducing content size, the system intelligently modifies the displayed portion and maintains appropriate aspect ratios to preserve content quality and immersion while adapting to the available display area in each state.
3Stability of the object's composition
If the aspect ratio is maintained while reducing content size, then the content proportion is preserved, but marginal areas are produced and usability deteriorates
Solution Approach 1:
The system dynamically changes display parameters including content area size, aspect ratio, and marginal area configuration based on the slideable section's position. This allows the display to optimize content presentation for each state, eliminating unnecessary marginal areas while maintaining appropriate content proportions, thereby improving usability without sacrificing compositional stability.
