Segmented Aging Pad for LCD Static Electricity Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Static electricity introduced during the aging process of liquid crystal display (LCD) fabrication can cause driver failure or malfunction due to the aging pad's design, which does not effectively minimize electrical interference.
Innovation Solution
The aging pad is designed with multiple sub-aging pads arranged in a matrix or at intervals, connected by a minimal-width connection pattern, reducing the overall area and minimizing static electricity generation, and is connected to the driving circuit through aging signal application wiring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the aging pad is designed with a simple structure for ease of manufacture, then manufacturing precision deteriorates due to static electricity introduction
Solution Approach 1:
The aging pad is divided into multiple sub-aging pads (first sub-aging pad, second sub-aging pad, third sub-aging pad, fourth sub-aging pad) arranged in a matrix pattern. This segmentation reduces the area of each individual pad, thereby minimizing static electricity generation while maintaining the overall functionality of the aging process. The segmented structure allows for easier manufacturing without compromising reliability.
2Object-affected harmful factors
If the aging pad area is reduced to minimize static electricity, then manufacturing precision deteriorates due to connection complexity
Solution Approach 1:
Multiple sub-aging pads are electrically connected through connection patterns to function as a unified aging pad structure. The connection patterns integrate the divided sub-pads while maintaining minimal area, ensuring that the reduced size does not compromise manufacturing precision. The merging of multiple small pads through electrical connections achieves both static electricity reduction and manufacturing feasibility.
3Object-affected harmful factors
If the aging pad is divided into multiple sub-aging pads, then device complexity increases, but static electricity introduction is minimized
Solution Approach 1:
The aging pad structure is segmented into four distinct sub-aging pads arranged in a 2x2 matrix, where each sub-pad is connected to specific gate lines and data lines. This segmentation effectively reduces the area of each pad, minimizing static electricity generation. The systematic arrangement and connection method maintain manageable device complexity while achieving the desired static electricity reduction.
