Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display devices in portable information processing devices face challenges in enhancing display quality while reducing volume and weight, and existing assembly methods are complex and difficult to assemble efficiently.
Innovation Solution
A display device design that includes a display panel, a backlight assembly, a housing member, a cover member, and a mold frame, where the display panel is bonded to the cover member using an adhesive member, and the cover member is coupled to the housing member and mold frame through coupling protrusions and grooves, simplifying the assembly process and enhancing structural integration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate components (display panel, backlight assembly, housing, cover) are used to achieve display quality and structural integrity, then display quality and reliability are improved, but device complexity and assembly difficulty increase
Solution Approach 1:
The patent combines the cover member with coupling protrusions and grooves that directly engage with the housing member and mold frame, merging the cover function with the coupling function into a single integrated component. This eliminates the need for separate coupling mechanisms and reduces the number of assembly steps while maintaining structural integrity through the bonded display panel-cover-housing-mold frame assembly.
2Stability of the object's composition
If traditional assembly methods with multiple separate components are used, then structural stability is maintained, but assembly efficiency and productivity decrease
Solution Approach 1:
The patent segments the coupling function into integrated features (protrusions and grooves) on the cover member, allowing the cover to be assembled with the housing and mold frame in a single operation. The display panel is bonded to the cover member, creating a pre-assembled unit that simplifies the overall assembly process while maintaining structural stability through the interconnected components.
3Illumination intensity
If display quality is enhanced through additional components and assembly steps, then image display performance is improved, but device volume and weight increase
Solution Approach 1:
The cover member serves multiple functions: it provides the structural cover for the display device, incorporates coupling protrusions and grooves for mechanical attachment to the housing and mold frame, and serves as a bonding surface for the display panel. This multi-functionality eliminates the need for separate components, reducing device volume and weight while maintaining display quality through the integrated assembly.

AI summary
A display device includes a display panel having a display area which displays an image and a non-display area positioned around the display area. The display device further includes a backlight assembly which emits light towards the display panel, and a housing member which houses the backlight assembly. The display device additionally includes a cover member having an opening portion corresponding to the display area, and which covers a portion of the display panel, and a mold frame coupled to the housing member. The display panel is bonded to the cover member, and at least a portion of the cover member is disposed in a space between the housing member and the mold frame, to couple the cover member to the housing member and the mold frame.
