Selective Desktop Projection for Large-Screen Display Area Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In conventional screen projection technologies, when an electronic device with multiple desktops projects its screen onto a large-screen device, all desktops are displayed, occupying a large area on the large-screen device and affecting user experience.
Innovation Solution
A display method and apparatus that allow the electronic device to selectively project only one or a subset of its desktops onto the large-screen device, with controls on the large-screen device to adjust the number of desktops displayed, improving display flexibility and user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all desktops of the electronic device are displayed on the large-screen device, then complete content projection is achieved, but a large area is occupied on the display and user experience is affected
Solution Approach 1:
The patent divides the multiple desktops into separate individual display units. Instead of projecting all desktops simultaneously as a single large interface, each desktop is segmented and can be projected individually or in selected combinations, allowing the user to choose which desktops to display and how much area they occupy on the large-screen device.
Solution Approach 2:
The patent implements dynamic control over the number and arrangement of displayed desktops. The system allows real-time adjustment of display configuration, enabling users to switch between displaying one desktop, multiple desktops, or all desktops based on current needs. This dynamic adaptability resolves the contradiction by making the display area flexible rather than fixed.
2Loss of information
If all desktops are projected onto the large-screen device, then comprehensive information is displayed, but operation efficiency is reduced due to large area occupation
Solution Approach 1:
The patent enables partial projection of desktops by allowing users to select and display only the necessary number of desktops rather than all desktops simultaneously. This partial action principle allows users to display exactly the information needed for current tasks, improving operation efficiency while maintaining information completeness when required.
Solution Approach 2:
The system provides dynamic switching between different display modes (single desktop, multiple desktops, all desktops), allowing users to quickly adapt the display configuration to match task requirements. This dynamic capability enhances operation efficiency by enabling fast transitions between focused single-desktop mode and comprehensive multi-desktop mode.
3Device complexity
If fixed display configuration is used for screen projection, then system simplicity is maintained, but display flexibility and user experience are limited
Solution Approach 1:
The patent implements a dynamic display configuration system that automatically adapts to different usage scenarios. The system can dynamically adjust the number of displayed desktops, their arrangement, and projection parameters based on user input or predefined scenarios, providing high flexibility while maintaining relatively simple system architecture through automated control.
Solution Approach 2:
The patent creates a universal projection system that can handle multiple display configurations (single desktop, multiple desktops, all desktops) and different projection scenarios within a single unified framework. This multi-functionality approach provides display flexibility without requiring separate systems for each configuration, thereby maintaining system simplicity.

AI summary
A display method and a related apparatus are disclosed. The display method is applied to an information interaction system. The information interaction system includes an electronic device (11) and a large-screen device (12). The method includes: The electronic device (11) obtains preset information, where the preset information includes information about an application installed on the electronic device (11), and the information about the application includes at least one of a name, an icon, and a package name of the application. The electronic device (11) generates a first window based on the preset information, where the first window includes any one of a plurality of desktops of the electronic device (11). The electronic device (11) sends the first window to the large-screen device (12), so that the large-screen device (12) displays a first user interface, where the first user interface includes the first window. This method can reduce an area that is occupied on a display of the large-screen device (12) by a projected window of the electronic device (11), and improve user experience.
