Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid crystal display panels face a productivity issue due to the long time required for curing the frame sealant, which is attributed to its larger volume.
Innovation Solution
The implementation of a liquid crystal display panel design that incorporates a sealing member with a boss structure, where the boss overlaps the frame sealant in the film thickness direction, reducing the thickness and volume of the frame sealant and thereby shortening the curing time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a frame sealant is placed between the array substrate and the color filter substrate to seal the liquid crystal cell, then the sealing function is improved, but the curing time increases due to the larger volume of the frame sealant
Solution Approach 1:
The frame sealant is segmented into two functional parts: a frame sealant layer for sealing and a boss structure for mechanical support and alignment. This segmentation allows the frame sealant volume to be reduced while maintaining sealing effectiveness, thereby reducing curing time without compromising reliability
Solution Approach 2:
The boss structure acts as an intermediary element between the array substrate and color filter substrate. It provides mechanical support and alignment functions that were previously required from the frame sealant itself, allowing the frame sealant to be thinned and reduced in volume, thus reducing curing time while maintaining sealing reliability
2Productivity
If the frame sealant thickness is reduced to shorten curing time, then the curing time and productivity are improved, but the sealing capability may be compromised
Solution Approach 1:
By segmenting the sealing function from the mechanical support function, the frame sealant can be optimized for sealing only, using thinner material that cures faster while the boss structure provides the necessary mechanical support to maintain sealing capability
Solution Approach 2:
The sealing member combines the frame sealant material with the boss structure material to form a composite sealing system. This composite structure allows each material to perform its optimized function, with the frame sealant providing sealing capability and the boss providing mechanical support, enabling reduced frame sealant thickness without compromising overall sealing reliability
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
This design effectively reduces the curing time for the frame sealant and enhances productivity by minimizing the volume of the frame sealant, addressing the long-standing issue of low productivity in conventional liquid crystal display panels.
Implementation Method 1
it is necessary to place a frame sealant between the array substrate and the color filter substrate. A thickness of the frame sealant typically equals the spacing between the array substrate and the color filter substrate. Due to the larger volume of the frame sealant, this results in a longer required light curing time for curing the frame sealant

AI summary
The embodiment of the present application discloses a liquid crystal display panel, the liquid crystal display panel includes a first substrate and a second substrate disposed opposite to each other. A frame sealant and a boss contacting each other are disposed in a frame sealant region, and the frame sealant at least partially overlaps the boss in a film thickness direction. A boss cooperating with the frame sealant to perform a sealing function is disposed in the frame sealant region. The boss reduces a volume of the frame sealant and lowers a time required for curing the frame sealant to improve a productivity.
