Display Apparatus Automatic Source Switching via Power State Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience when switching sources on display apparatuses, such as TVs, as they need to navigate through multiple menus and repeatedly press directional buttons to select a different content source.
Innovation Solution
A display apparatus and method that detects changes in the power mode of connected sources, allowing automatic or manual switching between sources based on power state changes, enabling users to switch sources more conveniently without extensive user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual source switching through menu navigation is used, then source switching capability is achieved, but user operation complexity increases
Solution Approach 1:
The display apparatus automatically detects power mode changes of connected sources and performs automatic source switching without requiring user intervention. The system monitors power states of multiple sources and autonomously selects the active source, eliminating the need for manual menu navigation and button pressing.
Solution Approach 2:
The system pre-configures multiple connection interfaces and continuously monitors their power states in advance. When a source is powered on, the system has already detected the power mode change and prepared for immediate switching, eliminating the need for users to navigate through menus after the source is activated.
2Ease of operation
If automatic source switching is implemented, then user convenience is improved, but control precision over source selection decreases
Solution Approach 1:
The system dynamically adapts its switching behavior based on user preferences. Users can configure whether they want automatic switching or manual selection through settings. The system adjusts its operation mode dynamically - performing automatic switching when configured to do so, or presenting manual selection options when the user prefers control, thus balancing convenience and precision according to user needs.
3Measurement precision
If multiple connection interfaces are monitored, then source switching accuracy improves, but system complexity increases
Solution Approach 1:
The system employs a universal power mode detection mechanism that can monitor multiple different connection interfaces (HDMI, USB, etc.) through a common detection methodology. The processor uses the same power detection logic across all interfaces, eliminating the need for separate complex monitoring systems for each interface type and reducing overall system complexity while maintaining multi-interface capability.

AI summary
A display apparatus is provided. The apparatus includes a display configured to display an image corresponding to a first connection interface of a plurality of connection interfaces; and a processor configured to, in response to detecting a change of a power state of an external apparatus connected to the display apparatus through a second connection interface of the plurality of connection interfaces, determine whether content is inputted through the first connection interface, and control the display to display a user interface (UI) indicating that source switch is available or display an image received through the second connection interface, based on a result of the determination.
