Liquid Crystal Cell Assembly with Frame-Like Seal Members
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid crystal cell manufacturing methods result in poor productivity due to the first and second substrate members having areas larger than the frame-like seal members, limiting the number of substrates that can be produced.
Innovation Solution
The method involves forming first and second substrate members with electrodes on cell regions, using frame-like seal members that link adjacent sides to define cell regions, and bonding them through these seal members, allowing for segmentation into individual liquid crystal cells along the defined perimeters and segmentation lines.

Engineering Contradiction Analysis
1Productivity
If the first and second substrate members are defined into substrate regions with shapes larger than the outer shape of the frame-like seal member, then the substrate regions can provide liquid crystal cell substrates, but the number of substrates that can be produced is limited, leading to poor productivity
Solution Approach 1:
The first and second substrate members are divided into multiple substrate regions that are arrayed in a grid pattern. Each substrate region is bounded by frame-like seal members and can be independently processed. This segmentation allows the substrates to be produced in a systematic manner, increasing the number of substrates that can be manufactured from each substrate member while maintaining manageable complexity through standardized regional definitions.
2Ease of manufacture
If the frame-like seal members surround the screen area in units of substrate regions, then the liquid crystal cell assembly can be formed, but the segmentation and separation process becomes complex
Solution Approach 1:
Multiple frame-like seal members that individually surround screen areas of adjacent substrate regions are merged to form a continuous frame structure. This merging eliminates the need for separate sealing operations at the boundaries between substrate regions, simplifying the assembly process. The continuous frame structure provides uniform sealing across multiple substrate regions while reducing the number of discrete sealing operations required.
Solution Approach 2:
The frame-like seal members are formed to define the boundaries of substrate regions before the bonding process. This preliminary definition of regional boundaries allows for pre-planned segmentation lines that guide the subsequent separation process. By preparing the seal member configuration in advance with built-in segmentation features, the overall manufacturing process becomes more streamlined and less complex.
3Area of stationary object
If the first substrate member has substrate regions with shapes larger than the frame-like seal member outer shape, then the substrate regions can be defined, but the area utilization is reduced
Solution Approach 1:
The substrate regions are defined with precise local boundaries that match the outer shape of the frame-like seal members. Each substrate region is optimized to maximize its usable area for liquid crystal cell substrate production. By aligning the substrate region boundaries with the seal member geometry, the design ensures that every portion of the substrate member contributes to productive substrate generation, eliminating wasted area while maintaining clear regional definitions.
