Multi-Display Electronic Device for Selective Image Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mirroring technologies in electronic devices are not suitable for multitasking, as they transmit the entire image output to external devices without allowing for different actions on the display, which can disrupt user intentions, such as viewing video content while receiving popup notifications.
Innovation Solution
An electronic device with multiple displays and a communication circuit that allows for simultaneous display and transmission of different screen images to an external device, enabling multitasking by controlling which images and actions are shared.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the entire image output on the display is transmitted to the external device using existing mirroring technology, then the external device can display the same content as the electronic device, but the user cannot perform different actions on the display while viewing content on the external device, disrupting multitasking capabilities
Solution Approach 1:
The display is divided into multiple independent display areas (first display area and second display area), each capable of showing different content. The electronic device can selectively transmit content from one display area to the external device while maintaining different content in other display areas, enabling multitasking without disrupting content synchronization for the shared content.
Solution Approach 2:
Different display areas are assigned different functions and content types. For example, the first display area may show video content that is mirrored to the external device, while the second display area shows notifications or messages that remain only on the electronic device. This local differentiation allows simultaneous content sharing and independent local interactions.
2Loss of information
If popup windows for notifications are displayed on both the electronic device and external device simultaneously, then all content is synchronized, but this does not align with user intent when the user wants to view video content privately on the external device without distractions
Solution Approach 1:
The system extracts and separates notification content from the main display content that is being mirrored. Popup windows or notification messages can be displayed only on the electronic device's local display areas, while the external device receives only the selected main content (e.g., video playback). This extraction prevents unwanted information from being transmitted while maintaining information completeness for the user.
3Device complexity
If the electronic device uses a single display for both content sharing and local interactions, then the device structure is simple, but the device cannot simultaneously perform multiple display functions with different purposes
Solution Approach 1:
The single display is segmented into multiple independent display areas that can function independently. Each display area can be configured for different purposes (e.g., one for mirroring to external devices, another for local notifications, another for control interfaces). This segmentation enables diverse display functions while maintaining a relatively simple single-display physical structure.
Data Source
AI summary
A method for displaying and transmitting images and an electronic device thereof are provided. The electronic device includes a first display, a second display separated from the first display, a transceiver, at least one processor electrically connected to the first display, the second display, and the transceiver, and a memory electrically connected to the at least one processor. The at least one processor is configured to display a first screen image on the first display, provide a second screen image on the second display at least partially simultaneously with the displaying of the first screen image on the first display, provide data associated with one of the screen images to the transceiver, and control the transceiver to transmit the data to an external device such that a screen image at least partially identical to one of the screen images is output on a display of the external device.
