Video Wall Fixing Apparatus with Shared T-Shape Top Case
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional video wall fixing apparatuses result in significant gaps between display panels due to the width and thickness of top cases, which detract from the seamless appearance of a single large screen and complicate installation and reconfiguration.
Innovation Solution
A fixing apparatus featuring T-shaped top case units with asymmetrical bezel frames and corner frames that allow neighboring display panels to share a single top case, reducing the gap between active areas and enabling modular, level positioning for a more integrated screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional top cases are used to fix display panels, then the display panels can be securely mounted, but significant gaps appear between the panels due to the width and thickness of the top cases
Solution Approach 1:
The top case is divided into two functional parts: a middle frame that fits into the recessed groove of the display panel (providing secure mounting) and a bezel frame that extends to the front surface (providing structural support). This segmentation allows the mounting function to be separated from the gap-creating structure, enabling secure attachment while minimizing the visible gap between panels.
Solution Approach 2:
The middle frame is inserted into a recessed groove formed in the display panel, creating a nested structure where the fixing apparatus is partially housed within the panel itself. This nesting approach allows the mounting mechanism to be concealed within the panel thickness, reducing the protrusion and resulting gap between adjacent panels while maintaining secure fixation.
2Strength
If top cases with significant thickness are used for structural support, then the video wall structure is more robust, but the gap between display panels increases
Solution Approach 1:
The structural support function is transitioned from a three-dimensional protruding top case to a two-dimensional bezel frame that extends along the front surface of the display panel. By distributing the structural support across the surface area rather than relying on thickness, the design achieves robustness while minimizing the gap between panels. The bezel frame can provide sufficient structural integrity through its extended surface area and connection to the middle frame.
3Ease of manufacture
If symmetrical top cases are used for simplicity of manufacture, then production is easier, but the bezel frame cannot be optimally positioned to minimize gaps
Solution Approach 1:
The bezel frame is designed with asymmetrical dimensions, allowing it to be optimally positioned relative to the middle frame and display panel boundaries. This asymmetry enables the bezel frame to extend further in directions where gap minimization is critical, while maintaining manufacturability through straightforward cutting and shaping processes. The asymmetrical design provides flexibility in positioning to achieve the smallest possible gaps between adjacent display panels.

AI summary
Disclosed is a fixing apparatus for a video wall to fix a plurality of display panels disposed in a lattice pattern, including a plurality of top case units each positioned between neighboring ones of the display panels, each of the top case units comprising a middle frame inserted between the neighboring ones of the display panels to extend to rear surfaces of the display panels, and a bezel frame extending from the middle frame to opposite sides in a perpendicular direction to the middle frame to cover ends of front surfaces of neighboring display panels, and a fastening member fastened to the middle frame extending to the rear surfaces of the display panels to fix the display panels. In the fixing apparatus, neighboring display panels share one top case, and thus the gap between the display panels for a video wall may be reduced.
