Electronic Device Screen Sharing with External Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with different platforms face challenges in sharing screens effectively due to variations in screen sizes and display configurations, limiting seamless content sharing across devices.
Innovation Solution
An electronic device equipped with a communication interface to receive screen size information from external display devices and a controller to determine a target screen size, adjusting display configuration parameters to match the target size, allowing for either screen sharing or independent display modes based on user input and device arrangement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If screen sharing is implemented between electronic devices with different platforms, then content sharing functionality is improved, but display compatibility and visual quality deteriorate due to different screen sizes and display configurations
Solution Approach 1:
The patent changes display parameters by detecting the external display device's screen resolution and adjusting the display configuration parameter accordingly. The controller modifies the display output parameters to match the external device's capabilities, transforming the display from the electronic device's native resolution to a compatible resolution that maintains visual quality across different platforms.
Solution Approach 2:
The controller acts as an intermediary between the electronic device's display system and the external display device. It receives detection information about the external device's screen characteristics and mediates the display output by adjusting configuration parameters, enabling seamless cross-platform screen sharing without direct platform-specific integration.
2Manufacturing precision
If display configuration parameters are adjusted to match external device screen size, then content display quality is improved, but system complexity increases due to additional detection and adjustment mechanisms
Solution Approach 1:
The system performs self-service by automatically detecting the external display device's screen characteristics and adjusting its own display configuration parameters without user intervention. The controller autonomously completes the entire process of detecting display information, determining appropriate configuration parameters, and applying the adjustments, reducing the need for complex manual configuration interfaces.
Solution Approach 2:
The system performs preliminary detection of the external display device's screen resolution and characteristics before initiating screen sharing. By obtaining detection information in advance and pre-adjusting the display configuration parameters, the system prepares the optimal display settings beforehand, avoiding the need for complex real-time adjustments during the screen sharing process.

AI summary
An electronic device receives a screen size of at least one external display device adjacent to the electronic device from the at least one external display device, determines a target screen size on the basis of the screen size of the electronic device and the screen size of the at least one external display device, and changes a display configuration parameter of the electronic device such that the screen size of the electronic device corresponds to the target screen size, thereby generating display data for sharing a screen with the at least one external display device.
