External Display Multi-Tasking via Emulator Execution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The limitations of display size in portable electronic devices, such as smartphones and tablets, restrict effective multi-tasking capabilities, as they often require screen splitting or conversion between applications due to their smaller screens compared to personal computers.
Innovation Solution
A method and apparatus that utilize an external display device to execute and manage multiple applications, allowing for seamless multi-tasking by determining which application screens to output to the external display, processing input and control signals, and managing audio transmission, thereby enhancing the multi-tasking experience without overwhelming the device's own screen.

Engineering Contradiction Analysis
1Productivity
If multiple applications are run concurrently on a portable electronic device, then multi-tasking capability is improved, but the limited display size causes screen space insufficiency and requires screen splitting or application conversion
Solution Approach 1:
The patent extends the display space from two dimensions (portable device screen) to three dimensions by utilizing an external display device. The electronic device transmits application screen information to the external display, effectively adding a spatial dimension for multi-tasking without increasing the physical size of the portable device itself.
Solution Approach 2:
The external display device serves as an intermediary between the electronic device and the user. It receives application screen information from the electronic device and presents multiple application interfaces simultaneously, mediating the space constraint issue by decoupling the computational device from the display device.
2Productivity
If application screens are transmitted to external display device, then multi-tasking space is improved, but device complexity increases due to emulator execution and signal management
Solution Approach 1:
The patent extracts the display function from the electronic device and places it in the external display device. The electronic device focuses on application execution while the external display handles the complex task of rendering multiple application screens simultaneously, reducing the complexity burden on the portable device.
Solution Approach 2:
The external display device creates copies of application screen information received from the electronic device. Instead of running multiple emulator instances on the portable device, the system transmits the original application screens and generates additional display copies on the external device, reducing computational complexity.

AI summary
A method and apparatus for performing multi-tasking using an external display device in an electronic device are provided. A method for performing a multi-tasking work using an external display device in an electronic device includes the operations of executing at least one application, determining whether to output an application screen to the external display device, in response to determining to output the application screen, sending an emulator execution request to the external display device, and, after sending the emulator execution request to the external display device, determining an application identifier in a screen of an application whose screen is determined to be outputted to the external display device, and transmitting a signal corresponding to the screen and the application identifier to the external display device.
