Display Panel Encapsulation Edge Shape for ESD-Safe Narrow Bezels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Designing the edge position of the encapsulation layer in ultra-narrow bezel or bezel-less display panels to ensure the performance and protection of light-emitting devices, while minimizing electrostatic damage and facilitating bonding processes.
Innovation Solution
The encapsulation layer is designed with different shaped portions in the first and second edge regions to provide varying electrostatic protection, featuring a curved surface in the first edge region to reduce static electricity accumulation and facilitate bonding, and includes a self-leveling process to form a smooth surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the encapsulation layer is extended to the edge of the display panel to provide electrostatic protection, then the protection against electrostatic damage is improved, but the bonding process becomes more difficult and the risk of static electricity accumulation increases
Solution Approach 1:
The encapsulation layer is designed with different shapes in different edge regions. The first edge region has a first shape that provides electrostatic protection, while the second edge region has a second shape that facilitates bonding. This local differentiation allows each region to optimize for its specific function, resolving the contradiction between electrostatic protection and bonding ease.
Solution Approach 2:
The encapsulation layer is segmented into multiple portions with different shapes rather than using a uniform design. The first encapsulation portion in the first edge region and the second encapsulation portion in the second edge region are distinct segments that serve different purposes, allowing the system to simultaneously achieve electrostatic protection and bonding facilitation.
2Reliability
If the encapsulation layer is designed with a curved surface to reduce static electricity accumulation, then the electrostatic protection is improved, but the manufacturing complexity increases
Solution Approach 1:
The curved surface design is applied locally to specific portions of the encapsulation layer where electrostatic protection is most needed, rather than making the entire encapsulation layer complex. This localized application of curvature reduces static electricity accumulation in critical areas while keeping the overall structure manageable.

AI summary
A display panel and a display apparatus. The display panel includes a first edge region, a second edge region, an array substrate, light-emitting devices, and an encapsulation layer disposed at a side of the light-emitting devices away from the array substrate. The array substrate includes a substrate and a side trace disposed in the first edge region. The side trace includes a first portion and a second portion electrically connected to each other. The first portion is disposed at a side of the substrate facing the encapsulation layer, and the second portion is disposed at a side of the substrate away from the encapsulation layer. A first encapsulation portion of the encapsulation layer is disposed in the first edge region, and a second encapsulation portion of the encapsulation layer is disposed in the second edge region. The first encapsulation portion has a different shape from the second encapsulation portion.
