Display Panel Wire Exchange Area Sealing Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display panels with narrow borders achieve this effect by bending non-display areas behind the display area, but this method does not effectively prevent water vapor from entering the display area, compromising display quality and reliability.
Innovation Solution
A display panel design featuring an array substrate with a flexible substrate, inorganic insulating and metal layers, and a packaging body with an inorganic layer that directly contacts the insulating layer in the wire exchanging area, forming a secure packaging area that prevents water vapor entry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the non-display area is bent to the back of the display area to achieve narrow border effect, then the border size is reduced, but water vapor can enter the display area through the wire exchanging area
Solution Approach 1:
The patent applies composite material structure by combining inorganic insulating layers (such as silicon oxide, silicon nitride) with organic flat layers to form a multi-layer packaging body. This composite structure provides both flexibility for bending and effective water vapor barrier properties, resolving the contradiction between achieving narrow borders through bending and maintaining sealing performance.
Solution Approach 2:
The inorganic insulating layer serves as an intermediary barrier between the wire exchanging area and the display area. It directly contacts the inorganic layer of the packaging body to form a packaging area, acting as a mediator that prevents water vapor penetration while allowing the structural bending needed for narrow borders.
2Shape
If the display panel is bent near the display area to fully bend the non-display area, then the narrow border effect is achieved, but the sealing structure becomes compromised
Solution Approach 1:
The patent implements local quality by providing inorganic insulating layers and metal layers specifically in the wire exchanging area where bending occurs. This localized reinforcement with inorganic materials (silicon oxide, silicon nitride) provides enhanced water vapor barrier properties exactly where the bending compromise would otherwise create vulnerability, allowing the rest of the panel to be fully bent for narrow borders.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enhances the sealing performance, improving the reliability and stability of the display panel by effectively blocking water vapor and preventing dark spots or bubbles from forming in the display area, thus ensuring better display quality and durability.
Implementation Method 1
The inorganic layer and the inorganic insulating layer are both formed of an inorganic material, a contact sealing effect thereof is good, water vapor is effectively prevented from entering the display area
