Flexible Display Background Rendering for Folded Screen Margins
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible electronic devices experience image distortion when bent, leading to unusable margin spaces on the display.
Innovation Solution
A method and electronic device that adjust and display main content without distortion by folding, utilizing a flexible display with a first and second face, and a processor to detect folding and positional relationships, displaying background content in the margin space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the display area is extended to provide more interactions and information, then the screen size increases, but image distortion occurs when the flexible display is bent
Solution Approach 1:
The patent segments the display area into a first area for displaying the main image and a second area (margin space) that appears when the display is bent. This segmentation allows the system to manage different display regions independently, enabling the main image to be displayed without distortion in the first area while utilizing the margin space in the second area for additional content or information.
Solution Approach 2:
The patent utilizes the third dimension of bending/folding to create a dynamic display experience. When the flexible display is bent, a margin space (second area) is created in addition to the main display area (first area). This dimensional change allows the system to provide more information and interactions without distorting the main image, as the additional content is placed in the margin space rather than expanding the main display area.
2Manufacturing precision
If the main image is displayed without distortion by reducing the display area, then image quality is maintained, but the margin space is wasted
Solution Approach 1:
The patent makes the margin space (second area) multi-functional by using it to display additional content, information, or controls. Instead of leaving the margin space empty or wasted, the system utilizes it for various purposes such as displaying notifications, quick settings, or supplementary information related to the main content. This multi-functionality ensures that the entire display area is effectively utilized while maintaining image quality in the main display area.
3Loss of information
If the display area is increased to show more content, then information quantity increases, but the main content becomes distorted when bent
Solution Approach 1:
The patent segments the information display into two distinct areas: the first area for the main content that remains undistorted, and the second area (margin space) for additional information that appears when bent. This segmentation allows the system to maintain high-quality display of primary content while providing supplementary information in the margin space without causing distortion to the main content.
Solution Approach 2:
The patent uses the bending dimension to create a margin space that provides additional information without interfering with the main content display. When the flexible display is bent, the margin space emerges as an additional display region where supplementary information can be shown. This dimensional approach allows the system to increase information quantity while keeping the main content undistorted, as the additional information is placed in the margin space rather than expanding the main content area.
Data Source
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.
