Flexible Display Background Filling for Fold-Induced Image Margins
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When a flexible electronic device is bent, the image displayed on the display becomes distorted, leading to a margin portion where the image is not visible, reducing usability.
Innovation Solution
The electronic device adjusts the main image to prevent distortion by folding and displays background content in the margin space using a flexible display, which includes a processor to detect folding and positional relationships, creating and positioning background content based on folding angles and user position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the display area is extended using a flexible display, then the screen size is increased, but image distortion occurs when the device is bent
Solution Approach 1:
The display area is segmented into a first area for displaying the main image and a second area for displaying the background image. This segmentation allows the system to manage different display regions independently, enabling the main image to be protected from distortion while utilizing the flexible display's extended area for additional content.
Solution Approach 2:
Different quality requirements are applied to different regions of the display. The first area maintains high image quality and geometric accuracy for the main image, while the second area can accommodate distorted or creatively transformed background content. This local differentiation resolves the contradiction by preserving main image quality while utilizing the flexible display's extended area.
2Manufacturing precision
If the main image is displayed without distortion, then a margin portion is created where the image is not displayed, but this reduces usability
Solution Approach 1:
The system merges the display of the main image in the first area with the display of the background image in the second area. By combining these two display functions, the margin space that would otherwise be wasted is utilized to provide additional useful information, thereby improving usability without compromising the quality of the main image.
Solution Approach 2:
The display is extended into another dimensional space by utilizing the flexible display's ability to create margin areas through bending. The background image is displayed in this additional spatial dimension (the second area), allowing the system to provide more content without interfering with the undistorted main image display.
3Ease of operation
If background content is displayed in the margin space, then the usability is enhanced, but the device complexity increases
Solution Approach 1:
The system performs preliminary actions by detecting the folding state of the flexible display and calculating the appropriate display areas before rendering the images. The processor determines the first and second areas based on the folding angle and curvature in advance, which simplifies the subsequent image rendering process and manages the overall system complexity.
Solution Approach 2:
The system implements feedback by continuously monitoring the folding angle and curvature of the flexible display, and using this information to dynamically adjust the display parameters. This feedback mechanism allows the system to adapt to different folding states automatically, managing complexity through intelligent control rather than hardware complexity.

AI summary
An electronic device is provided. The electronic device includes a flexible display divided into a first face and a second face with respect to a folding axis, and at least one processor operatively coupled to the display. The at least one processor is configured to display main content through a first area of the display, detect folding of the display while the main content is displayed, display the main content through a second area smaller than the first area, based on a folding angle of the display and a positional relationship between the electronic device and a user, and display background content in a third area which is an area excluding the second area. The background content is an image for filling a margin produced by displaying the main content in the second area.
