Liquid Crystal Panel Edge Sealing Structure Against Leakage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Liquid crystal panels suffer from leakage due to sealant corrosion by water vapor, leading to reduced production efficiency and assembly issues, as existing solutions like additional sealing processes complicate manufacturing and increase the risk of adhesive failure.
Innovation Solution
A liquid crystal panel design featuring a pressing body and groove body arrangement at the edges of glass substrates, with a sealing adhesive filling the gap between them, forming a protective barrier against water vapor and ensuring secure adhesion, using a groove body and pressing body structure to accommodate the adhesive and prevent leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the sealant width is reduced to achieve ultra-narrow frame design, then the frame area is narrowed, but the sealant becomes more susceptible to water vapor corrosion and liquid crystal leakage
Solution Approach 1:
The sealing structure is divided into two functional parts: the sealant for basic sealing and the pressing body with groove body for enhanced protection. This segmentation allows each component to specialize - the sealant provides the primary seal while the pressing body structure creates a barrier against water vapor, solving the contradiction between narrow frame width and sealant reliability.
Solution Approach 2:
The pressing body acts as an intermediary structure between the sealant and the external environment. It creates a protective barrier that prevents water vapor from directly contacting the sealant, thereby protecting the sealant from corrosion while allowing the frame area to be minimized.
2Reliability
If an additional sealing process with sealing adhesive is added to prevent liquid crystal leakage, then leakage risk is reduced, but production efficiency decreases and assembly problems increase
Solution Approach 1:
The sealing adhesive application and sealant formation processes are merged into a single integrated structure. The groove body is formed simultaneously with the sealant, and the sealing adhesive is applied in the same process step, eliminating the need for a separate sealing process and improving production efficiency while maintaining leakage prevention.
Solution Approach 2:
The groove body structure is prepared in advance during the sealant formation process, creating a pre-configured structure that guides the sealing adhesive placement. This preliminary action ensures proper adhesive positioning and bonding without requiring additional alignment or adjustment steps during assembly.
3Reliability
If sealing adhesive is added to prevent leakage, then leakage risk is reduced, but the adhesive is prone to collision and peeling during transport and assembly
Solution Approach 1:
The groove body structure acts as a protective shell that encloses and protects the sealing adhesive. This structural enclosure provides mechanical protection against collision and peeling forces during transport and assembly, while the adhesive maintains its bonding function within the protected groove structure.
Solution Approach 2:
The sealing adhesive is nested within the groove body structure, which itself is nested between the first and second glass substrates. This nested arrangement provides multiple layers of protection and constraint, preventing the adhesive from peeling or detaching during handling and assembly operations.

AI summary
A liquid crystal panel, a manufacturing method therefor and an application thereof. The liquid crystal panel comprises a first glass substrate (10), a second glass substrate (20), a liquid crystal layer (30), and a sealant (40). The sealant (40) is provided at the periphery of the liquid crystal layer (30) and used for sealing and assembling the first glass substrate (10) and the second glass substrate (20). The liquid crystal layer (30) is packaged between the assembled first glass substrate (10) and the second glass substrate (20). A circle of press (50) protruding toward the second glass substrate (20) is provided around the edge of the first glass substrate (10). A groove (60) for receiving the press (50) is formed on the second glass substrate (20). A gap between the groove (60) and the press (50) is filled with a sealing adhesive (70). The sealing adhesive (70) and the sealant (40) are prepared simultaneously, so as to solve the problem in the prior art of easy leakage of liquid crystals in the liquid crystal panel.
