Annular Wiring Area Bending for Array Substrate Border Width Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display panels with center via holes have a wide border due to the distribution of gate and data lines along the edge of the via hole, which is inefficient in terms of space utilization and aesthetics.
Innovation Solution
An array substrate with an annular wiring area around the via hole, featuring incisions extending toward the outer edge and portions of the wiring area bent away from the display side, reducing the width of the annular wiring area and thus the border around the via hole.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If gate lines and data lines are distributed along the edge of the center via hole, then the wiring structure is simple and easy to manufacture, but the border width around the via hole increases
Solution Approach 1:
The patent bends the annular wiring area from the inner edge toward the side away from the display side, transforming a two-dimensional planar wiring layout into a three-dimensional folded structure. This dimensional change allows the wiring to route around the via hole more efficiently, reducing the border width while maintaining manufacturing simplicity
Solution Approach 2:
The patent introduces incisions in the annular wiring area that extend toward the outer edge, dividing the continuous wiring structure into segmented regions. This segmentation enables the wiring area to be bent and folded without creating excessive stress concentration, resolving the contradiction between structural simplicity and compact border width
2Length of stationary object
If the annular wiring area is bent toward the side away from the display side, then the border width is reduced, but the wiring area may intersect with signal lines
Solution Approach 1:
The incisions divide the annular wiring area into multiple segments that can be independently bent and positioned. This segmentation allows precise control over the folding pattern, ensuring that bent portions avoid intersecting with signal lines while still achieving border width reduction
Solution Approach 2:
The patent applies different structural characteristics to different regions of the annular wiring area - some portions are bent while others remain planar. This local differentiation allows the wiring to navigate around signal lines in critical areas while achieving compact borders in other regions
