Display Device Region-Based Source Extraction for Multi-UI Services
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multi-UI service methods for electronic devices incur additional development and maintenance costs due to the need for separate applications for each operating system, and they often result in slowed data transmission speeds due to excessive data transfer.
Innovation Solution
A method and display device that divide the execution screen into regions, extract and transmit only the necessary source information to peripheral devices based on their proximity and capabilities, allowing efficient data communication and dynamic adjustment of the execution screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the conventional mirroring method is used to transmit content from the main device to the target device, then the multi-UI service can be provided among multiple electronic devices, but the data amount increases due to transmission of previously stored contents, which causes slowdown of data transmission speed
Solution Approach 1:
The patent extracts and transmits only the necessary source information (specific data elements required for the application) rather than transmitting all previously stored contents. This selective extraction of essential information reduces the overall data transmission volume while maintaining the multi-UI service functionality across multiple devices.
Solution Approach 2:
The patent segments the application data into source information that needs to be transmitted and other data that can remain stored. By dividing the data transmission into essential source information only, the system achieves faster transmission speeds while still enabling the target device to provide the required multi-UI service.
2Adaptability or versatility
If separate applications are developed for each operating system to enable multi-user participation, then each user can have their own application instance, but additional development and maintenance costs are incurred for each operating system
Solution Approach 1:
The patent implements a universal application structure where a single application can operate across multiple operating systems. The application receives user input and provides services through a common interface, eliminating the need to develop and maintain separate applications for each operating system while still enabling multi-user participation.
Solution Approach 2:
The patent introduces an intermediary layer (the service providing server) that handles the application logic and user input processing. This intermediary allows the application to function across different operating systems without requiring OS-specific implementations, reducing development and maintenance costs while maintaining multi-user capability.

AI summary
Disclosed are a display device and a method for controlling the same. The method for controlling a display device according to the present invention comprises the steps of: displaying an execution screen of an application which is divided into a plurality of regions; extracting source information related to a region, from among the plurality of regions, to be transmitted to a peripheral device; and transmitting the extracted source information to the peripheral device. Accordingly, the display device can more efficiently provide multi-UI services between a plurality of peripheral devices.
