Array Substrate Electrode Layout for Lower Signal Line Loading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid crystal display panel manufacturing processes result in uneven color and poor display performance due to misalignment of substrates, leading to increased material and cost burdens from signal line loading.
Innovation Solution
The method involves forming an electrode layer on a spacer unit layer, which increases the distance between the signal line and the electrode layer, reducing capacitance and eliminating the need for gold ball material and coating processes, thereby reducing material and cost.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the spacer unit layer is formed before the electrode layer, then the distance between signal line and electrode layer is increased, reducing capacitance and loading, but the manufacturing process complexity increases
Solution Approach 1:
The spacer unit layer is formed in advance before the electrode layer, creating a preliminary structure that increases the distance between the signal line and electrode layer. This preliminary action reduces capacitance and signal line loading while maintaining a manageable manufacturing process through sequential layer formation.
2Loss of substance
If the electrode layer is formed on the spacer unit layer, then material and cost are reduced by eliminating gold ball material and coating processes, but the manufacturing precision requirements increase
Solution Approach 1:
The invention extracts and eliminates the gold ball material and its associated coating processes from the manufacturing sequence. By forming the electrode layer directly on the spacer unit layer, the patent removes unnecessary material steps, reducing both material costs and process complexity while maintaining acceptable manufacturing precision through integrated layer formation.
