Solution Overview
Problem
Existing technologies for controlling external display devices via electronic devices face challenges in providing intuitive and efficient user input methods, leading to usability issues during screen mirroring and switching between applications.
Innovation Solution
The electronic device includes a processor that generates a virtual display corresponding to the external display, allowing for intuitive touch control through a control screen overlapping on the built-in display, processing user inputs to mirror and update the external display screen accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If screen mirroring is implemented to display content on external display device, then viewing area is improved, but control convenience deteriorates because user input processing becomes complex
Solution Approach 1:
The control screen is segmented into multiple functional areas corresponding to different applications or content types. Each segment can be independently controlled, allowing users to interact with specific portions of the external display without overwhelming complexity. The segmentation divides the control responsibilities into manageable units that map to specific display regions.
Solution Approach 2:
A control screen is introduced as an intermediary layer between the user and the external display device. This control screen receives user inputs on the electronic device's built-in display and translates them into appropriate control signals for the external display, simplifying the control process while maintaining the expanded viewing area benefits.
2Ease of operation
If control function is added between electronic device and external display device, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The control screen serves multiple functions: it displays control interfaces for various applications, receives user inputs, processes control signals, and communicates with the external display device. By making the control system multi-functional, the patent reduces overall complexity while improving ease of operation across different scenarios.
Solution Approach 2:
The control screen creates a virtual representation or copy of the external display's control interface on the electronic device's built-in display. This copying allows users to interact with the external display as if it were the built-in display, simplifying the control mechanism without requiring complex direct control protocols.
3Productivity
If real-time mirroring is implemented, then productivity is improved, but loss of information increases due to synchronization issues
Solution Approach 1:
The system implements feedback mechanisms where the control screen continuously monitors user inputs and synchronization status, adjusting the mirroring process accordingly. This feedback loop ensures that control actions are accurately reflected on the external display in real-time, preventing information loss while maintaining high productivity.
Solution Approach 2:
The control screen prepares and buffers control signals in advance, ensuring that synchronization information is ready before it is needed. This preliminary action prevents information loss by anticipating synchronization requirements and pre-processing control data, maintaining real-time productivity.

AI summary
An electronic device is provided. The electronic device includes a display, a communication circuitry, memory storing one or more computer programs, and one or more processors communicatively coupled to the display, the communication circuitry, and the memory, wherein the one or more computer programs include computer-executable instructions that, when executed by the one or more processors, cause the electronic device to connect to an external display device, display a first screen on the display, transmit, to the external display device, first data related to a second screen differing from the first screen, display a third screen corresponding to the second screen, on at least a portion of the first screen, and, in response to a touch input on the third screen, transmit updated second screen-related second data to the external display device via the communication circuitry.
