Blocking Portion Shunts Liquid Crystal Impact on Frame Sealant
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing liquid crystal display panel manufacturing process using drop-filling results in damage to the frame sealant due to the impact of liquid crystals, leading to potential scrapping of the display panel.
Innovation Solution
Incorporating a blocking portion with channels near the frame sealant in the non-display region to block and shunt the liquid crystals, reducing the impact force and preventing damage to the frame sealant during cell-assembling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If drop-filling method is used for liquid crystal injection, then injection speed is improved, but frame sealant is damaged due to impact force
Solution Approach 1:
A blocking portion is introduced as an intermediary structure between the liquid crystal injection area and the frame sealant. This blocking portion absorbs and dissipates the impact force of the liquid crystals, preventing direct damage to the frame sealant while maintaining the efficiency of the drop-filling method.
Solution Approach 2:
The blocking portion is positioned in advance before the liquid crystals reach the frame sealant. It serves as a cushioning structure that预先 absorbs the impact energy, protecting the frame sealant from damage before the harmful impact can occur.
2Reliability
If blocking portion is added to protect frame sealant, then frame sealant integrity is improved, but device structure becomes more complex
Solution Approach 1:
The blocking portion is not added throughout the entire display panel but only in specific local areas where liquid crystal impact is most likely to damage the frame sealant. This localized approach protects the frame sealant while minimizing the increase in overall structural complexity.
Solution Approach 2:
The blocking portion is divided into multiple segmented structures rather than a single large block. This segmentation allows the blocking function to be distributed across multiple smaller elements, reducing the overall structural complexity while maintaining protective effectiveness.

AI summary
The present disclosure provides a display panel and a display device, which can reduce damage to a frame sealant caused by impact of a photoelectric material on the frame sealant during cell-assembling of the display. The display panel includes a first substrate, a second substrate, and a frame sealant and a photoelectric material layer between them; the photoelectric material is in a liquid and flowing status, the photoelectric material layer is located in and covers a display region of the display panel, and the frame sealant is located in a non-display region of the display panel. The display panel further includes a blocking portion provided in the non-display region and at a side of the frame sealant near the display region for blocking the photoelectric material. The blocking portion includes a channel for shunting the photoelectric material so as to block impact of the photoelectric material on the frame sealant.
