Wireless Video Wall Modules Replace Cables
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of connecting power lines and cables in video walls composed of multiple image display devices makes installation inconvenient, especially when the arrangement changes or devices need to be replaced.
Innovation Solution
The implementation of first and second wireless communication modules on opposite surfaces of each image display device, allowing for rapid and efficient data transmission and power distribution between adjacent devices using short-range wireless communication, eliminating the need for physical cables.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If power lines and cables are connected to each image display device, then power and signals can be transmitted, but the connection becomes complicated and installation becomes inconvenient
Solution Approach 1:
The patent replaces mechanical cable connections with wireless communication technology. Image display devices transmit and receive power and signal data wirelessly through wireless communication modules, eliminating the need for physical power lines and cable connections between devices.
2Loss of information
If cables are used for connecting image display devices, then data transmission is established, but installation efficiency decreases when arrangement changes or devices are replaced
Solution Approach 1:
The patent replaces mechanical cable connections with wireless communication technology. Image display devices transmit and receive power and signal data wirelessly through wireless communication modules, eliminating the need for physical power lines and cable connections between devices.
3Reliability
If multiple cables are connected for power and signals, then all necessary connections are established, but the overall system becomes harder to install and maintain
Solution Approach 1:
The patent combines power transmission and data signal transmission into a single wireless communication channel. The wireless communication modules integrate both power delivery and data communication functions, eliminating the need for separate power lines and signal cables.

AI summary
An image display device and a video wall including the same are disclosed. The image display device includes a housing, a display configured to display an image, a first wireless communication module disposed on one surface of the housing, and a second wireless communication module disposed at a position on an opposite surface of the housing corresponding to a position of the first wireless communication module. The first wireless communication module and the second wireless communication module transmit and receive a signal through the same short-range communication method. Various other embodiments are possible.
