Multi-Cabinet Display Processor Activation via Sensor Signals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in controlling external electronic devices installed in separate spaces while using large display devices, as they cannot easily access or activate these devices while viewing images.
Innovation Solution
A display apparatus comprising multiple cabinets with sub-processors and processors that can activate each other based on sensor signals, allowing remote control of external electronic devices through a network of sensors and interfaces, enabling activation and deactivation of processors and devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the external electronic device is installed in a separate space from the display device, then the display device can be placed in a convenient location for viewing, but the user cannot easily control the external electronic device while watching images
Solution Approach 1:
The display apparatus acts as an intermediary device between the user and the external electronic device. It receives control signals from the user through its sensor and transmits these signals to the external electronic device via network communication, enabling remote control without requiring the user to physically access the external device's location
Solution Approach 2:
The display apparatus is designed with multi-functionality, serving both as an image display device and as a control device for external electronic devices. By integrating control functionality into the display apparatus, users can control external devices from the display device's location, eliminating the need for separate control mechanisms
2Speed
If multiple processors are continuously activated in all cabinets, then the system is ready to respond immediately to user inputs, but power consumption increases significantly
Solution Approach 1:
The system dynamically adjusts the operational state of processors based on real-time conditions. Processors transition between activated and inactivated states depending on whether user presence is detected and whether control operations are needed, optimizing the balance between response readiness and power consumption
Solution Approach 2:
The sub-processor remains in a stand-by mode with preliminary readiness to activate the main processor when needed. This preliminary state allows the system to quickly respond to user inputs while consuming minimal power, as the full processor activation only occurs when actually required
3Ease of operation
If the processor is kept in an activated state for remote control capability, then control responsiveness is improved, but power consumption increases
Solution Approach 1:
The sub-processor maintains a stand-by state with preliminary readiness to activate the main processor when control operations are needed. This allows the system to be prepared for remote control without continuously activating the full processor, reducing power consumption while maintaining responsiveness
Solution Approach 2:
The system uses its own sensor to detect user presence and automatically determines when processor activation is needed. This self-service mechanism eliminates the need for continuous activation while ensuring timely response when users are present, optimizing both responsiveness and power efficiency

AI summary
A display apparatus includes a plurality of cabinets arranged adjacently to each other to provide a display screen, at least one sensor, and a main processor. Each cabinet of the plurality of cabinets includes a display module, a sub-processor configured to be activated in a stand-by mode, and a processor. A first sub-processor included in a first cabinet connected to the sensor, among the plurality of cabinets, is configured to, based on a signal being received from the sensor in the stand-by mode, activate a first processor in an inactivated state included in the first cabinet, and provide state information of the first processor to a second sub-processor included in a second cabinet that is adjacent to the first cabinet, and the second sub-processor is configured to activate the first processor using the state information in the stand-by mode.
