Display Panel Partition Wall Layout for Moisture-Safe Openings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display panels face challenges in integrating components such as speakers, sensors, or cameras within the display area without compromising the integrity and functionality of the display, particularly in maintaining effective encapsulation and preventing moisture ingress through openings.
Innovation Solution
A display panel design featuring a substrate with an opening, partition walls, and an encapsulation layer that includes an organic material layer extending into an intermediate area with specific opening portions, a stopper layer, and a second electrode extending into the intermediate area, along with a metal stack, to ensure structural integrity and moisture protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If components such as speakers, sensors, or cameras are integrated within the display area, then the functionality and versatility of the display panel is improved, but the integrity and moisture protection of the display may be compromised
Solution Approach 1:
The display panel is divided into distinct functional zones: a display area for light-emitting elements, an intermediate area with partition walls for component integration, and an opening area. The partition walls create separate compartments that allow component integration while maintaining moisture barriers for the display area.
Solution Approach 2:
Partition walls serve as intermediary structures between the display area and the opening area where components are integrated. These partition walls extend from the substrate and provide both structural separation and moisture protection, allowing the display to maintain integrity while accommodating additional functionality.
2Adaptability or versatility
If openings are created in the substrate for component integration, then the versatility of the display panel is improved, but moisture ingress through the openings becomes a risk
Solution Approach 1:
The encapsulation layer is applied to the light-emitting elements and extends into the intermediate area before the final assembly is completed. This preliminary encapsulation creates a moisture barrier in advance, preventing moisture ingress through the openings where components will be integrated.
Solution Approach 2:
The encapsulation layer combines organic and inorganic materials to create a composite barrier structure. This composite encapsulation layer provides enhanced moisture protection while allowing the openings to remain accessible for component integration and light transmission.
3Reliability
If the encapsulation layer is extended into the intermediate area to prevent moisture ingress, then the moisture protection is improved, but the structural complexity increases
Solution Approach 1:
The partition walls serve multiple functions simultaneously: they provide structural separation between the display area and component area, act as support structures for the encapsulation layer, and contribute to the overall mechanical integrity of the display panel. This multi-functionality reduces the need for additional separate components.
Solution Approach 2:
The encapsulation layer is merged with the partition wall structure, where the encapsulation material is deposited over and integrated with the partition walls. This combining of structures simplifies the overall design compared to having separate encapsulation and partition systems.
