Insulating Organic Compensator for Array Substrate Recesses
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display screens with high screen-to-body ratios suffer from poor display effects due to defects in the insulating layer, such as recesses or gaps, which can lead to short circuits and reduced yield, especially in narrow frame designs.
Innovation Solution
An array substrate with an insulating organic compensator is used to fill recesses in the insulating sub-layer, preventing metal from entering these defects and avoiding short circuits, thereby improving the display effect and yield.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single insulating layer is used to separate wiring layers, then the structure is simple and manufacturing is easier, but recesses or gaps in the insulating layer can cause metal to enter and create short circuits, reducing reliability
Solution Approach 1:
The insulating layer is segmented into multiple functional layers: an insulating sub-layer providing base insulation and an insulating organic compensator layer that compensates for surface recesses. This segmentation allows each layer to perform its specific function optimally, preventing metal intrusion while maintaining manufacturing feasibility.
Solution Approach 2:
The insulating organic compensator is formed in advance to pre-compensate for surface recesses before the upper wiring layer is deposited. This preliminary action ensures that the metal layer is deposited on a compensated surface, preventing metal from entering recesses and causing short circuits.
2Ease of manufacture
If the insulating layer surface is left as-is, then manufacturing is simpler, but metal can enter recesses causing short circuits and requiring complex removal processes
Solution Approach 1:
The insulating organic compensator is formed in advance to pre-compensate for surface recesses before the upper wiring layer is deposited. This preliminary action ensures that the metal layer is deposited on a compensated surface, preventing metal from entering recesses and causing short circuits.
Solution Approach 2:
The insulating organic compensator provides preliminary anti-action by preemptively filling and compensating for surface recesses, thereby preventing the harmful effect of metal intrusion before it can occur during the wiring layer formation process.
