Multi-Display Side Wiring Layout to Reduce Short-Circuit Risk
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In known multi-displays, the side wirings of adjacent display devices can come into contact, causing electrical short-circuiting, deterioration, damage, or breakage, leading to reduced operational and long-term reliability and display quality due to stress from vibrations or thermal expansion.
Innovation Solution
The multi-display design features first and second display devices with side wirings that do not face each other, ensuring they are located adjacent without overlap, with protective layers and strategic positioning to minimize contact and stress, thereby reducing the likelihood of short-circuiting and damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If side wirings of adjacent display devices are positioned to face each other, then electrical connection between devices is achieved, but the risk of contact, short-circuiting, and damage increases due to vibrations and thermal expansion
Solution Approach 1:
The patent positions side wirings on different surfaces (first side surface vs. second side surface) of adjacent display devices, utilizing the third dimension to separate components that would otherwise be in the same plane. This spatial separation in multiple dimensions prevents contact while maintaining electrical connection functionality.
Solution Approach 2:
The patent divides the wiring arrangement into separate, non-overlapping segments on different surfaces. By segmenting the wiring paths and placing them on distinct surfaces of adjacent devices, the design eliminates the harmful interaction between side wirings while preserving individual wiring functionality.
2Area of stationary object
If side wirings are positioned close to each other for compact design, then device density increases, but the risk of deterioration and breakage due to stress from vibrations increases
Solution Approach 1:
The patent utilizes three-dimensional space by positioning side wirings on different surfaces of adjacent display devices. This dimensional separation allows compact overall design while providing sufficient spatial buffer to reduce stress concentration and protect wiring integrity from vibration-induced damage.
Solution Approach 2:
The patent design inherently provides protective spacing and spatial separation before stress can accumulate to damaging levels. By positioning wirings on different surfaces, the design creates a buffer zone that cushions against the effects of vibrations and thermal expansion before they can cause deterioration or breakage.
3Reliability
If side wirings extend from side surfaces to display surfaces, then electrical connection is established, but contact with adjacent device side wirings causes short-circuiting
Solution Approach 1:
The patent extends side wirings from different surfaces (first side surface and second side surface) into the third dimension, allowing electrical connection while maintaining spatial separation. This dimensional approach enables wiring extension functionality without the harmful side effect of contact-induced short-circuiting between adjacent devices.
Solution Approach 2:
The patent segments the wiring extension paths by assigning them to different surfaces of adjacent display devices. This segmentation ensures that while wirings extend to establish electrical connections, they remain in separate spatial zones that prevent short-circuiting between adjacent devices.

AI summary
A multi-display includes a first display device and a second display device. The first display device includes a first substrate including a first display surface and a first side surface continuous with the first display surface, a first display portion on the first display surface, and a first side wiring extending from the first side surface to the first display surface. The second display device includes a second substrate including a second display surface and a second side surface continuous with the second display surface, a second display portion on the second display surface, and a second side wiring extending from the second side surface to the second display surface. The first side surface and the second side surface are adjacent to and face each other. The first side wiring and the second side wiring are located without facing each other.
