Array Substrate Encapsulation Layout for Curved Bezel Signal Lines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices suffer from improperly disposed dams in the curved area of the lower bezel, leading to wire breakage and affecting the display effect.
Innovation Solution
The array substrate includes a display area and a non-display area with dams and an encapsulation layer, where the encapsulation layer completely covers the first signal line, ensuring a flat non-display area and reducing the risk of wire breakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the dam is disposed in the curved area of the lower bezel, then the signal line can be routed through the non-display area, but the wire is prone to breakage affecting display effect
Solution Approach 1:
The patent extends the encapsulation layer beyond the display area boundary into the non-display area, creating a three-dimensional protective structure that covers the signal line from the side. This dimensional extension allows the signal line to be protected without changing its routing path, resolving the contradiction between ease of routing and wire breakage resistance.
Solution Approach 2:
The encapsulation layer is designed to cover the signal line in advance, providing protective cushioning before any potential damage can occur. The encapsulation layer acts as a pre-established protective barrier that prevents wire breakage in the curved area of the lower bezel.
2Manufacturing precision
If the encapsulation layer covers the signal line in the non-display area, then the non-display area becomes flat improving yield, but the structure becomes more complex
Solution Approach 1:
The encapsulation layer serves multiple functions: it provides the required flatness in the non-display area for manufacturing precision, simultaneously protects the signal line from breakage, and maintains structural integrity. This multi-functionality resolves the contradiction by making the additional structure serve multiple purposes rather than adding complexity without benefit.

AI summary
An array substrate and a display device. The array substrate includes a display area and a non-display area at least partially surrounding the display area. The array substrate includes a substrate, at least one first signal line, at least one dam, and an encapsulation layer. The at least one first signal line is disposed on one side of the substrate. At least part of a first signal line is first signal lines are disposed in the curved area of the non-display area. The at least one dam is disposed in the non-display area and disposed on a side of the at least one first signal line away from the substrate. The orthographic projection of the encapsulation layer on the substrate covers the orthographic projection of the first signal line on the substrate.
