Display Frame Coupling Mechanism for Narrow Bezel Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices with large bezel areas distort images and detract from viewing pleasure when multiple units are connected to form a multi-display device, as they create non-display areas on the screen, necessitating a structure that minimizes bezel width while maintaining stiffness.
Innovation Solution
A display device design featuring a first frame with fixing projections and a second frame with holes for engagement, along with a direct downward type backlight assembly and optical components like diffusion plates and sheets, which are fixed to the frames to maximize the display area and minimize bezel width, ensuring structural integrity.

Engineering Contradiction Analysis
1Area of stationary object
If the bezel area of the display device is reduced to minimize non-display areas, then the display area is maximized, but the structural stiffness of the frame may be compromised
Solution Approach 1:
The frame is divided into multiple segments with fixing projections and fixing holes that can be assembled together, allowing the frame to maintain structural integrity while reducing overall bezel area. The segmented structure provides reinforcement at key connection points without requiring a larger continuous frame.
Solution Approach 2:
The frame structure incorporates localized reinforcement through fixing projections and holes at specific critical positions rather than uniformly thickening the entire frame. This allows the frame to maintain stiffness where needed while minimizing material usage and bezel area in non-critical regions.
2Area of stationary object
If the bezel width is minimized to enhance viewing experience, then the valid screen area is maximized, but the structural integrity and support for internal components may be compromised
Solution Approach 1:
The frame is segmented into multiple parts that can be assembled using fixing projections and holes, providing distributed structural support across the minimized bezel width. This segmentation allows for optimized placement of reinforcement elements without increasing overall bezel dimensions.
Solution Approach 2:
The frame structure utilizes composite construction with multiple components (frame body, fixing projections, reinforcement elements) that work together to provide enhanced structural integrity within a minimized bezel width, combining different structural features to achieve both compactness and strength.
