Array Substrate Dummy Region Open Area Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display apparatuses often experience poor display quality at the periphery due to process residues, such as etching solutions, which can cause short circuits and affect the display effect.
Innovation Solution
The array substrate design includes a display region with first pixel regions and a dummy region with second pixel regions, where the second open regions are larger than the first open regions, allowing process residues to accumulate in the dummy region, reducing their impact on the display region and improving display quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the array substrate uses a conventional design without a dummy region, then the manufacturing process is simpler, but process residues cause short circuits and poor display quality at the periphery
Solution Approach 1:
The array substrate is segmented into a display region and a dummy region. The dummy region contains second pixel regions with larger open regions that serve as dedicated zones for collecting process residues, separating them from the display region to prevent short circuits and improve display quality.
Solution Approach 2:
The dummy region acts as an intermediary zone between the manufacturing process and the display region. By providing a buffer area with larger open regions, it mediates the impact of process residues, allowing them to accumulate harmlessly rather than causing short circuits in the display region.
2Reliability
If the array substrate includes a dummy region with larger open regions, then process residues are effectively collected and display quality improves, but the manufacturing process becomes more complex
Solution Approach 1:
The open region area parameter is changed in the dummy region compared to the display region. Second pixel regions in the dummy region have larger open regions, which changes the physical parameter to enable better residue collection while maintaining compatibility with existing manufacturing processes.
3Reliability
If the open regions in the dummy region are made larger, then process residues accumulate more effectively, but the area ratio of open region to pixel region increases significantly
Solution Approach 1:
Different regions of the array substrate are given different local qualities. The display region maintains its original open region size for optimal display performance, while the dummy region has enlarged open regions specifically for residue collection, allowing each region to optimize its function independently.
