Dual-Screen Terminal Display Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dual-screen display technologies do not support simultaneous display of two screens, leading to differing display effects and resolutions, which limits user customization and efficiency.
Innovation Solution
A method for a terminal to switch display modes by determining the display way for each screen based on user selection, allowing content to be displayed on one or both screens, with options for single-screen, large-screen, and mirroring modes, adjusting resolutions and content distribution accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If dual-screen display method is used with different display modes, then display customization and user experience are improved, but display coordination and consistency between screens deteriorate
Solution Approach 1:
The patent implements dynamic display mode switching that allows the terminal to transition between single-screen mode, large-screen mode, and mirroring mode based on user needs. The system dynamically adjusts display parameters, content distribution, and screen coordination strategies for each mode, enabling both high adaptability and maintained display coordination through mode-specific optimization rather than a fixed approach
Solution Approach 2:
The patent changes display parameters such as resolution, refresh rate, and content scaling factors according to the selected display mode. In large-screen mode, the system adjusts resolution allocation and content scaling to optimize for extended display area, while in mirroring mode, it maintains identical parameter settings across both screens to ensure display consistency, thus resolving the contradiction between customization and coordination
2Device complexity
If simultaneous display of two screens is not supported, then system complexity is reduced, but display efficiency and productivity deteriorate
Solution Approach 1:
The patent segments the display system into distinct operational modes (single-screen, large-screen, mirroring), each with its own coordinated control logic. This segmentation allows the system to manage dual-screen complexity through modular mode handling rather than attempting to manage all possible simultaneous display scenarios at once, thereby maintaining manageable system complexity while enabling efficient multi-screen productivity when needed
3Adaptability or versatility
If different resolutions are used for two display screens, then display adaptability to different screen specifications is improved, but display effect consistency deteriorates
Solution Approach 1:
The patent applies local quality by allowing different display parameters and content rendering strategies for different screens based on their specific resolutions and capabilities. In large-screen mode, each screen is optimized for its native resolution with appropriate content scaling and allocation, while in mirroring mode, both screens use identical parameter settings. This localized optimization for each screen's characteristics achieves display adaptability while maintaining effect consistency within each operational mode

AI summary
A method of switching display of a terminal and a terminal are disclosed. The method of switching display includes: obtaining a display mode of the terminal selected by a user, herein the terminal includes a first display screen and a second display screen; determining a display way of an output object on the first display screen and the second display screen according to the display mode selected by the user; and displaying the output object on at least one of the first display screen and the second display screen according to the determined display way.
