Array Substrate Repair Line Segmentation for Signal Integrity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current repair line structures in flat display manufacturing cross over multiple signal lines, leading to resistive-capacitive (RC) loading and signal transmission decay, making them ineffective in maintaining proper function as the number of crossings increases.
Innovation Solution
The introduction of at least two sub-lines from the repair line, which cross over different signal line groups, reducing RC loading by minimizing the number of signal lines each sub-line intersects, and allowing for targeted electrical connection to defective lines through the insulation layer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single repair line crosses over multiple signal lines, then the repair structure can cover more signal lines, but the resistive-capacitive (RC) loading increases and signal transmission quality deteriorates
Solution Approach 1:
The single repair line is divided into multiple sub-lines (first sub-line and second sub-line), each crossing over different groups of signal lines. This segmentation reduces the RC loading on each individual sub-line while maintaining comprehensive coverage of all signal lines through the collective action of multiple sub-lines.
2Productivity
If the repair line crosses over more signal lines, then more defects can be repaired, but the decay in signal transmission becomes worse
Solution Approach 1:
The repair line is segmented into multiple sub-lines to reduce RC loading per sub-line, and the insulation layer is selectively penetrated at specific locations to create targeted electrical connections. This allows multiple defects to be repaired while maintaining signal transmission quality by limiting the number of crossings per sub-line.
Solution Approach 2:
The insulation layer is penetrated only at specific locations where defects occur, rather than along the entire length of the repair line. This localized penetration approach creates electrical connections only where needed, reducing unnecessary RC loading and maintaining signal transmission quality while still enabling repair of multiple defects.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach mitigates signal decay caused by RC loading, ensuring the repair line functions effectively and maintains signal transmission quality even as defects occur in multiple signal lines.
Implementation Method 1
the repair line and the insulation layer are penetrated by melting for the defected signal line so as to be connected to the corresponding repair line

AI summary
An array substrate includes: a base having an active region and a peripheral region adjoining to the active region; a plurality of signal lines disposed on the base; and at least one repair structure disposed on the peripheral region and having at least one first repair line and at least one second repair line having a first sub-line and a second sub-line. The first sub-line is located between the first repair line and the second sub-line. The signal lines have a plurality of groups; the first repair line crosses over at least two of the groups of the signal lines; and at least one of the groups of the signal lines is crossed over by only one of the first sub-line and the second sub-line.
