Display Panel Cover-Housing Coupling for Moisture-Resistant Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices face issues with increased size, manufacturing complexity, and vulnerability to moisture and foreign substances due to protective cover members and housings, which can damage the display panel and limit installation space.
Innovation Solution
A display device design featuring a cover member with a first bent portion and groove, coupled with a housing having a protrusion, reduces size and simplifies manufacturing by eliminating additional parts, while incorporating a groove to store and evaporate moisture, and a viewing angle control unit to prevent view dispersion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cover member and housing are added to protect the display panel, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent merges the cover member and housing into an integrated structure where the housing serves as both the protective enclosure and the mounting structure for the display panel. This consolidation reduces the number of separate components while maintaining the protective function against moisture and foreign substances.
Solution Approach 2:
The housing is designed to perform multiple functions simultaneously: it provides mechanical protection, serves as a mounting structure for the display panel, and includes integrated sealing features to prevent moisture ingress. This multi-functionality reduces the need for additional dedicated protective components.
2Reliability
If a cover member and housing are added to protect the display panel, then reliability is improved, but manufacturing cost increases
Solution Approach 1:
By combining the cover member and housing into a single integrated component, the manufacturing process is simplified. Instead of producing and assembling multiple separate protective parts, the integrated design allows for single-step molding or forming, reducing manufacturing complexity and cost.
3Reliability
If a cover member and housing are added to protect the display panel, then reliability is improved, but device size increases
Solution Approach 1:
The display panel is nested within the housing structure, which provides protective walls that contain the panel while maintaining a compact overall form factor. The protective structure is integrated into the housing volume rather than adding external layers, optimizing space utilization.
4Reliability
If additional parts are added to couple protective components, then reliability is improved, but device complexity increases
Solution Approach 1:
The coupling function is merged into the housing structure itself, which includes integrated mounting features and sealing elements that directly secure the display panel without requiring separate coupling parts. This integration eliminates additional components while maintaining secure attachment.

AI summary
A display device including a display panel configured to display images; a cover member disposed on the display panel and including a first flat portion, a first bent portion bent from the first flat portion, and a first groove formed in the first bent portion; and a housing disposed below the display panel and including a second flat portion and a second bent portion bent from the second flat portion. Further, the second bent portion of the housing has a protrusion coupled to the first groove of the cover member. In addition, the display panel includes a display substrate, a thin film transistor array on the display substrate, a light emitting layer on the thin film transistor array, an encapsulation part on the light emitting layer, a support member disposed below the display substrate, and a heat dissipation plate disposed below the support member.
