Display Panel Spacer Limiting Groove Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In liquid crystal display (LCD) technology, spacers between substrates are prone to sliding under external forces, affecting the stability and leading to potential light leakage and display issues due to inadequate support.
Innovation Solution
The introduction of a first limiting groove and a first limiting protruding strip on one substrate, where the spacer end extends into the groove, creating a gap between the spacer and the groove wall, allowing for deformation and increased contact area, thereby enhancing the spacer's stability and preventing dislocation of substrates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the spacer is freely placed between substrates without limiting structures, then the manufacturing process is simple, but the spacer slides under external force affecting support stability
Solution Approach 1:
The substrate is segmented by creating a limiting groove that divides the space where the spacer can move, confining it to a specific region. This segmentation approach prevents the spacer from sliding freely while maintaining manufacturing simplicity
Solution Approach 2:
The limiting protruding strip acts as an intermediary element between the spacer and the substrate. It provides a contact surface that prevents spacer sliding without requiring complex structural modifications to the substrate itself
2Reliability
If the spacer is tightly constrained by the groove wall, then the spacer position is fixed, but the spacer cannot deform under external force reducing support effectiveness
Solution Approach 1:
The limiting groove provides localized constraint only at the edges where needed, while the center region allows spacer deformation. This local quality approach ensures positional stability without compromising structural integrity
Solution Approach 2:
The gap between the spacer and groove wall is designed in advance to anticipate and accommodate deformation under external force. This preliminary anti-action prevents the spacer from being overly constrained while maintaining position stability

AI summary
A display panel and a display device are disclosed. The display panel includes a first substrate and a second substrate that are aligned and bonded together, and further includes a spacer disposed between the first substrate and second substrate. One end of the spacer is disposed on the second substrate, and the other end faces the first substrate. The first substrate further includes a first limiting groove that is disposed on one side adjacent to the second substrate and that corresponds to a position of the spacer. The other end of the spacer extends into the first limiting groove. A first limiting protruding strip is disposed on a groove wall of the first limiting groove, and the surface of the first limiting protruding strip facing the spacer abuts against the side wall of the spacer, defining a gap between the spacer and the groove wall of the first limiting groove.
