Virtual Screen Module for Dual-Display Image Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dual-screen output systems for electronic devices, such as notebook computers, lack multiple application modes and fail to effectively integrate interactions between screens, resulting in inefficient touch-responsive performance and tedious data transmission.
Innovation Solution
An electronic device with a first screen, a second screen, a virtual screen module, and a processor that generates a virtual screen signal to integrate virtual screen image information with second screen image information into an integrated image data stream, allowing for various application modes and efficient output between screens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional dual-screen output system is used, then the system can display content on two screens, but it cannot provide multiple application modes for different situations
Solution Approach 1:
The patent implements multiple application modes (full-screen mode, windowed mode, picture-in-picture mode, and edge display mode) within a single dual-screen output system, allowing the system to adapt to different usage scenarios without requiring separate configurations or hardware setups
2Ease of operation
If a conventional dual-screen output system is used, then the system can output to two screens, but effective interaction between screens is not realized
Solution Approach 1:
The patent merges the display content from the first screen into the second screen output through integrated image processing, enabling seamless picture-in-picture and edge display modes where content from both screens is combined into a unified display output, eliminating the need for manual content transfer between screens
3Productivity
If a conventional dual-screen output system is used, then the system can display on two screens, but touch-responsive efficiency is low
Solution Approach 1:
The patent replaces traditional hardware-based display output mechanisms with software-controlled virtual screen technology, allowing the processor to dynamically generate and switch between different display modes (full-screen, windowed, picture-in-picture, edge display) through software instructions rather than requiring physical hardware reconfiguration, thereby improving touch-responsive efficiency
4Ease of operation
If a conventional dual-screen output system is used, then the system can output image data streams, but the transmission procedure is tedious
Solution Approach 1:
The patent introduces a virtual screen as an intermediary layer between the processor and the physical displays. The processor outputs image data to the virtual screen, which then routes and processes the content according to the selected application mode (full-screen, windowed, picture-in-picture, or edge display), simplifying the transmission procedure by centralizing the routing logic in software

AI summary
A control method is provided. The control method is applied to an electronic device. The control method includes the following steps: detecting a virtual screen signal; allocating a virtual screen image buffer module for temporarily storing virtual screen image information according to the virtual screen signal; integrating the virtual screen image information and second screen image information into an integrated image data stream by a direct mode; outputting a first screen image data stream to a first screen of an electronic device, so that the first screen displays a first image according to the first screen image data stream; and outputting the integrated image data stream to a second screen of the electronic device, so that the second screen displays a second image according to the integrated image data stream.
