LCD Panel Impurity Blocking Structure for Seal Hardening Issues
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing LCD panels face issues with impurities forming due to unsatisfactory hardening of seals, which can lead to decreased display characteristics as these impurities flow into the active regions, affecting light transmittance and image quality.
Innovation Solution
Incorporating an impurity blocking and liquid crystal flowing structure within the seal to prevent impurities from entering the active region while allowing liquid crystals to flow freely, thereby maintaining uniform diffusion and improving display characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a seal made of thermosetting resin or ultraviolet-curable resin is used to bond display plates, then the seal can prevent liquid crystal leakage and protect liquid crystal cells, but the seal may not harden satisfactorily due to fabrication or material problems, causing contact reaction with liquid crystals and forming impurity particles
Solution Approach 1:
A liquid crystal blocking structure is introduced as an intermediary element between the seal and the liquid crystal layer. This blocking structure prevents direct contact between liquid crystals and the seal, thereby eliminating the formation of impurity particles even when the seal does not harden properly. The blocking structure acts as a mediator that isolates the two components.
Solution Approach 2:
The space between the seal and the liquid crystal layer is segmented by introducing a liquid crystal blocking structure. This segmentation creates distinct zones: one for the seal, one for the blocking structure, and one for the liquid crystal layer, preventing harmful interactions while maintaining the sealing function.
2Reliability
If the seal is made to prevent liquid crystal leakage, then liquid crystal retention is improved, but impurities from the seal can flow into the active region, decreasing display characteristics
Solution Approach 1:
The liquid crystal blocking structure serves as an intermediary barrier that allows the seal to maintain its liquid crystal retention function while preventing impurity particles from reaching the active region. The blocking structure is positioned to intercept impurities before they can flow into the display area.
Solution Approach 2:
The blocking structure converts the potential harm of impurity flow into a beneficial separation function. By introducing this additional element, the system transforms the problem of seal impurities into an opportunity to create a dedicated blocking zone that protects the active region while maintaining sealing integrity.
3Object-generated harmful factors
If a liquid crystal blocking structure is introduced to prevent impurity flow, then display characteristics are improved, but the device complexity increases
Solution Approach 1:
The liquid crystal blocking structure is designed to perform multiple functions simultaneously: it blocks impurity particles from flowing into the active region, maintains the cell gap between display plates, and prevents liquid crystal leakage. By combining multiple functions into a single structure, the overall device complexity is minimized while achieving the desired impurity blocking effect.
Solution Approach 2:
The blocking structure merges the functions of impurity blocking, spacing, and sealing support into a single integrated component. This merging reduces the number of separate elements needed in the device, thereby limiting the increase in complexity while achieving comprehensive impurity protection.

AI summary
A liquid crystal display (LCD) panel with improved display characteristics includes a first display plate and a second display plate which face each other with a liquid crystal layer therebetween, a seal bonding the first display plate to the second display plate to prevent leakage of the liquid crystal layer, and an impurity blocking and liquid crystal flowing structure disposed inside a perimeter of the seal to prevent impurities from flowing from the seal to an active region in the first and second display plates while providing a flow path allowing liquid crystals to flow to the seal.
