Flexible Sliding Display for Aspect Ratio Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The letter box area on a display hinders the sense of immersion for users when the aspect ratios of content and the display are mismatched.
Innovation Solution
An electronic device with a flexible display that adjusts its exposed area and display direction based on sliding operations, using sensors to identify optimal aspect ratios and orientations for full-screen content presentation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the display area is fixed to match a specific aspect ratio, then the manufacturing precision is improved, but the adaptability to different content aspect ratios deteriorates
Solution Approach 1:
The flexible display area is made dynamically adjustable through sliding operation. The display region can be extended or reduced in size along the sliding direction, allowing the display to adapt its aspect ratio dynamically to match different content requirements while maintaining manufacturing precision of the display panel itself
Solution Approach 2:
The physical parameter of the display area (size and aspect ratio) is changed through mechanical sliding operation. By adjusting the exposed area of the flexible display, the system transforms the display parameters to match the content aspect ratio, resolving the contradiction between fixed manufacturing precision and variable adaptability
2Adaptability or versatility
If the exposed area of the flexible display is extended to maximize content display, then the user immersion is improved, but the device complexity increases
Solution Approach 1:
The housing is divided into movable and fixed portions, with the second housing capable of sliding relative to the first. This segmentation allows the display area to be adjusted independently through the sliding mechanism, enabling flexible content display while managing device complexity through modular design

AI summary
An example electronic device includes a first housing, a second housing connected with the first housing and configured to perform a sliding operation, a driving device that adjusts the sliding operation, a flexible display, at least one sensor, and at least one processor. The processor is configured to control the electronic device to display content via at least a portion of a first area of the flexible display, identify an aspect ratio of the content, obtain orientation information of the electronic device using the sensor, and identify size information of a second area of the flexible display capable of maximally displaying the content with the identified aspect ratio of the content based on the obtained orientation information, the first area and the second area being one surface of an exposed area of the flexible display, and the second area being an area extended or reduced from the first area.
