Projector Interface Daisy Chain Control
Solution Overview
Problem
Existing display device systems with daisy chain connections require cumbersome user operations to manage function availability based on connection status, as users need to manually switch settings for each interface, which is inefficient.
Innovation Solution
A method for controlling display devices that selects and determines the compliance of interfaces for daisy chain connections, automatically transitioning to prevent function execution if the selected interface is not compliant, and prioritizing HDMI or HDBaseT interfaces for seamless daisy chain operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users manually switch settings for each interface to manage function availability, then function availability can be controlled, but operation complexity increases and usability deteriorates
Solution Approach 1:
The display device automatically detects the connection status of multiple interfaces and self-adjusts function availability without user intervention. The control section monitors interface connections and autonomously enables or disables daisy chain functions based on detected connection states, eliminating the need for manual user configuration.
Solution Approach 2:
The system dynamically changes the operational parameters (function availability) based on the detected connection status of different interfaces. When a compliant interface is detected, the system automatically enables daisy chain functions; when non-compliant interfaces are connected, the system automatically disables these functions, adapting parameters in real-time without user input.
2Adaptability or versatility
If multiple interfaces are provided for different connection purposes, then adaptability improves, but interface selection complexity increases
Solution Approach 1:
The control section performs preliminary detection of interface connection status before functions are activated. By pre-identifying which interfaces are connected and their compliance status, the system prepares the appropriate function availability settings in advance, preventing user confusion about which interface to use for which purpose.
Solution Approach 2:
The system dynamically adjusts interface functionality based on real-time connection status. The control section continuously monitors interface connections and automatically reconfigures which functions are available on which interfaces, allowing the system to adapt its behavior to the current connection state without requiring user reconfiguration.
3Ease of operation
If automatic interface selection is implemented, then ease of operation improves, but risk of selecting wrong interface increases
Solution Approach 1:
The control section continuously monitors feedback from multiple interfaces regarding their connection status and compliance characteristics. Based on this feedback, the system intelligently determines the appropriate interface for daisy chain connections and automatically configures function availability, ensuring accurate interface selection while maintaining ease of operation.

AI summary
A projector includes a selection section configured to select an interface to which an image signal to be displayed by the projector out of the plurality of interfaces is input, a determination section configured to determine whether or not the interface selected is a compliant interface capable of establishing daisy chain connection, and a function control section configured to make the transition of the projector to a state of preventing a daisy chain function from being executed when the interface selected is not the compliant interface, and when the daisy chain function which can be executed in a state in which the projector is coupled to another projector with the daisy chain connection is set available.
