Multi-display Device Bezel Reduction via Segmented Chassis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi-display devices face challenges in minimizing the bezel area, which leads to incomplete image display at the boundaries between connected display devices, as traditional chassis designs obstruct the rear side of transparent displays and fail to properly fix and protect the display panels.
Innovation Solution
A multi-display device design that uses a thin or small-dimension fixing member, such as double-sided adhesive tape, to securely attach the chassis to the display panel at the boundaries between adjacent devices, minimizing the bezel size and ensuring accurate image display by using symmetrical chassis configurations with protruding portions and coupling members for secure fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a bottom chassis covering the entire rear side of the display panel is used, then the display panel is protected and fixed, but the rear side cannot display an image because it is wholly shielded
Solution Approach 1:
The chassis is divided into four separate side chassis (first, second, third, and fourth chassis) that attach to the four sides of the display panel, replacing the traditional single bottom chassis. This segmentation allows the rear side to be partially exposed for image display while maintaining structural support and protection through the distributed side-mounted chassis configuration.
2Reliability
If traditional chassis designs are used, then the display panel is fixed and protected, but the bezel area is large which prevents accurate image display at boundaries
Solution Approach 1:
The fixing members are strategically positioned at the boundaries between adjacent display devices, specifically at corners or edges where chassis meet. This localized fixation approach minimizes the bezel area in non-boundary regions, allowing for accurate image display across most of the display surface while maintaining secure fixation at critical boundary points.
3Area of stationary object
If a thin fixing member is used to minimize bezel size, then the bezel area is reduced, but the fixation strength may be insufficient
Solution Approach 1:
The fixing member serves multiple functions simultaneously: it acts as a structural connector between chassis and display panel, provides precise positioning at boundaries, and enables secure fixation through threaded coupling. By combining these functions into a single integrated component, the design achieves strong fixation with minimal bezel area.
Solution Approach 2:
The fixing member is constructed as a composite structure with a thin body (for minimal bezel profile) and threaded coupling portions (for strong mechanical fastening). This composite design allows the component to be thin in the visible bezel area while maintaining high fixation strength through the threaded engagement mechanism.
