Liquid Crystal Display Supporter Segmentation for Aperture Ratio
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In liquid crystal displays, the accumulation of solid content from alignment materials on the outer surface of supporters due to surface tension leads to a decrease in aperture ratio and transmission rate, causing lumping and subsequent deterioration of pixel area performance.
Innovation Solution
A liquid crystal display design featuring a supporter divided into multiple portions to define a filling space, allowing the alignment material to fill within these spaces and reducing contact with the outer surface, thereby preventing lumping and maintaining a higher aperture ratio and transmission rate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a single supporter is used on the liquid crystal injection port to prevent roof layer drooping, then the roof layer is supported effectively, but the solid content of the alignment material accumulates on the outer surface causing lumping and decreased aperture ratio
Solution Approach 1:
The single supporter is divided into multiple supporters (first supporter and second supporter) that are positioned at different locations on the liquid crystal injection port. This segmentation reduces the surface area of each individual supporter, thereby reducing the accumulation of solid content on each supporter's outer surface while maintaining overall support capability for the roof layer.
2Strength
If the supporter surface area is large to provide sufficient support, then the roof layer is well-supported, but the solid content accumulates too thickly on the surface lowering transmission rate
Solution Approach 1:
By dividing the large supporter surface into multiple smaller supporter surfaces, the patent reduces the total outer surface area available for solid content accumulation. This segmentation maintains sufficient support capability through multiple support points while minimizing the thickness of accumulated solid content, thereby preserving transmission rate.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design effectively reduces the accumulation of solid content on the supporter's surface, thereby minimizing the decrease in aperture ratio and enhancing the transmission rate of the pixel area.
Implementation Method 1
In the process of injecting the alignment material that includes a solid content and a solvent into the fine space layer through the liquid crystal injection port and drying the injected alignment material
Implementation Method 2
a large amount of the solid content of the alignment material comes in contact with an outer surface of the supporter due to surface tension
