Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic apparatuses are limited in providing services from OS-based applications different from their own operating system, failing to meet user demands for variety in services.
Innovation Solution
A display apparatus and control method that connects a dongle with a different OS to a display device, allowing the display of execution screens from applications stored in the dongle and enabling user commands to execute and communicate with the dongle, thereby supporting multiple OS-based applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a display apparatus uses only its own OS-based applications, then system stability is maintained, but service variety is limited
Solution Approach 1:
The system is divided into two independent parts: the display apparatus running its native OS and the dongle running a different OS. This segmentation allows each component to maintain its own operating system without conflict, enabling the display apparatus to access applications from multiple OS environments while keeping the core system stable and simple.
Solution Approach 2:
The dongle acts as an intermediary device between the user and the display apparatus. It contains a different OS and applications, and communicates with the display apparatus through a standardized interface (HDMI-CEC), allowing the display apparatus to access diverse applications without directly integrating multiple OSes, thus maintaining system simplicity while enhancing service variety.
2Adaptability or versatility
If the display apparatus integrates multiple OS-based applications, then service variety increases, but system complexity increases
Solution Approach 1:
The dongle serves as an intermediary that encapsulates the complexity of multiple OSes. Users interact with applications from different OSes through a unified interface provided by the display apparatus, while the dongle handles the complexity of running different operating systems in the background, thus maintaining ease of operation while providing service variety.
Solution Approach 2:
The display apparatus is designed to universally support applications from different OSes through a standardized interface. The HDMI-CEC interface enables the display apparatus to communicate with and control applications running on the dongle's different OS, making the system multi-functional without requiring separate interfaces for each OS, thereby maintaining ease of operation.
3Adaptability or versatility
If the display apparatus connects to a dongle with different OS, then application compatibility improves, but connection management complexity increases
Solution Approach 1:
The HDMI-CEC interface acts as an intermediary that simplifies connection management between the display apparatus and the dongle. It provides standardized protocols for detecting the dongle's presence, establishing communication, and controlling applications, thereby reducing the complexity of managing connections between devices with different OSes while improving application compatibility.

AI summary
A display apparatus includes a display, an interface, and a processor configured to, based on a dongle in which an application is stored being connected to the interface, display the application stored in the dongle on the display based on information on the application received from the dongle, and based on receiving a user command for selecting the application displayed on the display, transmit a command for executing the selected application to the dongle through the interface, and based on receiving an execution screen of the application executed in the dongle through the interface according to the command, display the received execution screen on the display The processor is further configured to, based on receiving the user command, transmit, through the interface, a command for communicating with an electronic apparatus, so that the dongle is connected to the electronic apparatus.
