Videowall IR Disable Controller for Multi-Screen Remote Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-screen display systems require complex steps to select which displays can be controlled by a remote controller, and existing solutions do not efficiently enable or disable information receivers across multiple displays simultaneously.
Innovation Solution
A multi-screen display apparatus with a controller that enables the information receiver of one display device while disabling all others, using a manual on/off switch and communication connectors like UART for daisy chain connection, allowing a single display to act as the primary receiver for remote control signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple display devices have independent information receivers enabled, then each display can be controlled individually, but the control process becomes complex and time-consuming
Solution Approach 1:
The patent introduces a controller as an intermediary device that manages multiple information receivers. The controller receives control signals and selectively activates/deactivates specific receivers based on which display device is currently selected, eliminating the need for complex manual control of each receiver individually while maintaining individual display control capability
2Measurement precision
If manual selection steps are required to choose which display receives control signals, then control precision is maintained, but operation time increases
Solution Approach 1:
The system performs preliminary configuration by establishing a mapping between display devices and information receivers in advance. When a user selects a display device, the controller already has the predetermined information needed to quickly activate the corresponding receiver, eliminating time-consuming manual selection steps while maintaining accurate control signal routing
3Adaptability or versatility
If all information receivers are kept active, then any display can be controlled at any time, but interference between receivers occurs
Solution Approach 1:
The system dynamically adjusts the state of information receivers based on operational needs. Instead of keeping all receivers permanently active, the controller activates only the specific receiver corresponding to the currently selected display device, thereby maintaining control flexibility while preventing interference between receivers by ensuring only one is active at a time

AI summary
A multi-screen display apparatus comprising: (i) a plurality of display devices in an array, wherein each display device comprises a screen, an information receiver for receiving information from a remote control device and an on/off switch for enabling and disabling the information receiver; (ii) at least one connector for allowing the display devices to communicate with each other; and (iii) at least one controller configured to control each information receiver and each on/off switch, wherein the at least one controller is configured such that when a first on/off switch on a first display device is activated, the at least one controller enables the information receiver of said first display device and disables all other information receivers in the array.
