Dual-Display App Interface Switching for Aspect-Ratio Mismatch
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices struggle with image distortion when connected to external displays of different sizes or aspect ratios, limiting multitasking capabilities and preventing simultaneous utilization of both displays for different purposes.
Innovation Solution
An electronic device with a processor that identifies and outputs separate user interfaces on the first and second displays, allowing independent control of display states and magnification adjustments based on user inputs, enabling seamless interaction between the displays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the image outputted on the display of the electronic device is duplicated as it is on the external display, then the external display can be connected and used, but the image may be distorted when the display sizes or aspect ratios are different
Solution Approach 1:
The system changes display parameters such as resolution, aspect ratio, and scaling factors to match the characteristics of different external displays. The processor detects the external display's specifications and adjusts the output image parameters accordingly to prevent distortion while maintaining compatibility across various display types.
2Ease of operation
If the image is duplicated as it is on the external display, then connection is simple, but the user cannot utilize the external display and the display of the electronic device for different purposes
Solution Approach 1:
The system segments the display output into separate, independently controllable interfaces for the electronic device's display and the external display. Each display can show different content from the same application, allowing the user to utilize both displays for different purposes simultaneously while maintaining simple connection through automatic detection.
3Adaptability or versatility
If separate user interfaces are identified and output on different displays, then multitasking is enabled, but the system complexity increases
Solution Approach 1:
The processor implements a universal display management system that can automatically adapt to different display configurations (single display, external display only, or both displays). The same application can generate multiple user interfaces tailored to different display characteristics, enabling multitasking without requiring separate hardware or complex manual configuration.

AI summary
An electronic device is provided. The electronic device includes a first display, a memory configured to store an application, and a processor configured to while executing the application, in response to a connection between a second display different from the first display and the electronic device, output a first user interface and a visual object which is displayed on the first user interface and is related to the second display in the first display, by using the application, in response to a first input of a user related to the visual object, identify a second user interface by using the application, while outputting the first user interface in the first display, output the identified second user interface in the second display, and in response to a second input of the user on the first user interface, change a display state of the first user interface.
