Display Baseplate Signal Layout for Corrosion-Resistant Via Holes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display technologies face issues with corrosion of connecting via holes between signal lines and gate line driving circuits due to insufficient distance from the sealant, leading to reduced reliability and lifespan of display products.
Innovation Solution
The display baseplate design rearranges signal lines and gate line driving circuits such that signal lines closer to the display region are positioned to increase the distance from the sealant, minimizing corrosion risk and enhancing reliability by reducing the width of the frame without increasing its size.

1Length of stationary object
If signal lines are positioned closer to the gate line driving circuit, then the frame width can be reduced, but the connecting via holes become more susceptible to corrosion from sealant
Solution Approach 1:
The patent introduces a vertical dimension (first direction perpendicular to the second direction) to arrange signal lines and gate line driving circuits. By utilizing this additional spatial dimension, the design achieves compact layout with reduced frame width while maintaining sufficient horizontal distance between signal lines and sealant, thus preventing corrosion without increasing overall frame size.
Solution Approach 2:
The patent applies different spatial arrangements to different regions: signal lines are positioned in the first direction away from the sealant location, while the gate line driving circuit is arranged in the second direction. This localized quality differentiation ensures that via holes connecting signal lines to the driving circuit remain sufficiently distant from the sealant, preventing corrosion while achieving compact design.
2Reliability
If signal lines are positioned away from the sealant, then corrosion resistance improves, but the frame width increases
Solution Approach 1:
The patent utilizes two perpendicular directions (first direction perpendicular to second direction) to arrange components. Signal lines are positioned in the first direction away from the sealant, while the gate line driving circuit extends in the second direction. This dimensional arrangement achieves adequate corrosion protection distance without proportionally increasing frame width, as the components are efficiently packed in the vertical dimension.
Solution Approach 2:
The patent changes the spatial arrangement parameters by introducing perpendicular direction positioning. Instead of linear arrangement that would require increased frame width, the design uses two-dimensional coordinate positioning where signal lines and driving circuits are offset in different directions, maintaining compact overall dimensions while ensuring sufficient separation distance for corrosion prevention.
