Multi-Point Conductive Portions for Display Panel Metal Layer Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Connections between different metal layers in traditional display panels are prone to burning, leading to panel failure during electrical testing.
Innovation Solution
Incorporating multiple conductive portions between metal layers to ensure reliable electrical connections, with at least two conductive portions spaced apart to maintain connectivity even if one is damaged.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional single conductive portion connections are used between metal layers, then the device complexity is low, but the reliability of electrical connections deteriorates due to easy burning
Solution Approach 1:
The conductive connection between metal layers is divided into multiple separate conductive portions instead of using a single continuous conductor. Each conductive portion is spaced apart from the others, creating segmented connection points that reduce current density at any single location and prevent burning while maintaining electrical connectivity.
2Reliability
If conductive portions are placed close together to ensure connection, then the electrical connectivity is maintained, but the risk of burning increases due to higher current density
Solution Approach 1:
The connection is segmented into multiple spaced-apart conductive portions, distributing the current across multiple discrete locations rather than concentrating it in a single path, thereby reducing current density and burning risk at each individual portion.
Solution Approach 2:
The conductive portions are arranged in a spaced-apart configuration that utilizes spatial distribution to reduce current density. By separating the conductive portions in space rather than concentrating them, the design reduces thermal and electrical stress at any single point.

AI summary
A display panel, a display device, and a display system are provided. The display panel includes a plurality of conductive portions. Each of the conductive portions is respectively disposed between corresponding metal layers to be electrically connected in the display panel, and is used to electrically connect with the metal layers to be electrically connected. At least two conductive portions are provided between any two of the metal layers to be electrically connected. The at least two conductive portions are used for an electrical connection to realize multi-point connection of different metal layers, which improves a reliability in a conversion of different metal layers.
