Expandable Display Magnification Control for Continuous Work
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When a user of an electronic device expands or retracts a display, previously displayed data is not visible while scrolling, making continuous work difficult.
Innovation Solution
An electronic device with a display that maintains or changes its magnification based on specified inputs, application information, or user content, ensuring that data remains visible and usable during expansion or retraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the display area is expanded or retracted, then the display size is changed to improve productivity, but the previously displayed data becomes invisible during scrolling making continuous work difficult
Solution Approach 1:
The patent applies dynamics by making the display magnification adjustable and changeable based on user input and application type. The system dynamically transitions between different magnification states (first magnification value and second magnification value) to optimize both information visibility and productivity for different usage scenarios
Solution Approach 2:
The patent changes the display magnification parameter from a fixed state to a variable state. By introducing multiple magnification values and allowing transitions between them based on expansion/retraction states and application characteristics, the system resolves the contradiction between maintaining information visibility and enabling continuous work
2Area of stationary object
If the display magnification is maintained at the first value during expansion, then data visibility is preserved, but the expanded display area is not fully utilized
Solution Approach 1:
The system dynamically adjusts magnification based on the display expansion state and application type. When the display is expanded and the application supports it, the system transitions to a second magnification value that better utilizes the expanded area while maintaining data usability, resolving the contradiction between area utilization and ease of operation

AI summary
An example may include a display in which a display area of the display is expandable and retractable, a memory, and a processor operatively connected to the display and the memory, wherein the memory includes instructions causing, when executed, the processor to: display an execution screen of a running application on the display area at a first magnification value; expand the display area on the basis of a first designated input; based at least in part on the first designated input, information related to the application, and a first user content included in the execution screen, determine whether to maintain a display magnification of the display at the first magnification value or change the display magnification to a second magnification value different from the first magnification value; and display the execution screen on the expanded display area based on the determined display magnification.
