Virtual Display Screen Segmentation for Seamless Content Projection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large-size terminals typically display only one interface, leading to underutilization and a poor user experience due to the need to interrupt content display when changing the content, which limits the viewing experience.
Innovation Solution
A terminal system that creates a virtual display screen and projects a second interface to a connected terminal, allowing seamless display changes without interrupting the user experience by using a processor to generate and control both the first and second display interfaces, and project the second interface onto a virtual screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If only one display interface is shown on the large-size terminal, then the display system is simple, but the terminal is not effectively utilized and user viewing experience deteriorates
Solution Approach 1:
The patent divides the single physical display screen into multiple virtual display screens (first virtual display screen, second virtual display screen, etc.), allowing different content to be displayed simultaneously on different virtual screens. This segmentation enables effective utilization of the terminal screen while maintaining manageable complexity through virtualization
Solution Approach 2:
The patent introduces a projection control module as an intermediary that manages the mapping relationship between physical display screens and virtual display screens. This intermediary handles the complexity of multi-interface management, allowing the system to display multiple interfaces simultaneously while keeping the control mechanism organized and manageable
2Adaptability or versatility
If the content displayed on the large-size terminal is changed, then new content can be shown, but the display of current content is interrupted and viewing experience deteriorates
Solution Approach 1:
By segmenting the display into multiple virtual screens, the system allows content switching on one virtual screen without affecting other virtual screens. Users can switch between different content on different virtual display screens simultaneously, eliminating display interruptions and maintaining continuous viewing experience
Solution Approach 2:
The patent ensures continuous display of content by allowing multiple virtual display screens to operate simultaneously. When content needs to be changed on one virtual screen, other virtual screens continue displaying their content without interruption, maintaining the continuity of useful action across the entire display system

AI summary
A first terminal configured for screen projection includes a first processor and a first display screen. The first terminal is communicatively connected to a second terminal. The first processor is configured for: generating a first display interface, and controlling the first display screen to display the first display interface; creating a virtual display screen; creating a second display interface, and controlling the virtual display screen to display the second display interface; and projecting to the second terminal the second display interface corresponding to the virtual display screen, thereby causing the second terminal to display the second display interface.
