Adjustable Bracket Structure for Tiled Display Panel Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly of tiled display devices is hindered by segment differences between adjacent sub-display panel modules, leading to inefficiencies in assembly and potential display seams, which affect the flatness and display quality of the tiled display.
Innovation Solution
A bracket structure with a transfer motion adjustor is introduced, featuring a body with a support surface, an assembly surface, and side surfaces. The transfer motion adjustor includes rotation members and guide members that allow for adjustable protrusion on the assembly surface, enabling precise alignment and flatness adjustment of the sub-display panel modules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If multiple sub-display panel modules are assembled together to form a tiled display device, then the display size and expandability are improved, but segment differences between adjacent modules cause assembly difficulties and display seams
Solution Approach 1:
The bracket structure is divided into multiple adjustable support points (first support point, second support point, third support point, fourth support point) that can independently adjust the position of adjacent sub-display panel modules. This segmentation allows each module to be precisely positioned to eliminate segment differences while maintaining the overall large display area.
2Manufacturing precision
If adjustable support structures are added to eliminate segment differences, then alignment precision is improved, but device complexity increases
Solution Approach 1:
The bracket structure employs a nested design where the first and second guide members are received within the first bracket body, and the third and fourth guide members are received within the second bracket body. The guide members are nested within the adjustors, creating a compact hierarchical structure that reduces overall complexity while maintaining adjustment functionality.
Solution Approach 2:
The bracket structure uses universal adjustors that can perform multiple functions: positioning in the first direction (via first and second guide members) and positioning in the second direction (via third and fourth guide members). This multi-functionality eliminates the need for separate adjustment mechanisms for each direction, reducing overall device complexity.
3Ease of manufacture
If manual adjustment methods are used for bracket positioning, then ease of manufacture is improved, but assembly time and productivity are reduced
Solution Approach 1:
The adjustors are designed with self-adjusting features where the guide members automatically align with the guide holes through the adjustment process. The first guide member adjusts along the first guide hole, and the second guide member adjusts along the second guide hole, allowing the structure to self-correct positioning errors without requiring complex external adjustment tools or procedures.

Function Achieved in This Case
The bracket structure effectively adjusts the height of the support surface, ensuring that multiple sub-display panel modules are aligned in the same plane, thereby improving the display effect and assembly efficiency of the tiled display device.

AI summary
Embodiments of the present disclosure provide a bracket structure, a sub-display panel module, and a tiled display device. The bracket structure includes a body and at least one transfer motion adjustor. The body has a support surface, an assembly surface, and at least one side surface including a first side surface. The transfer motion adjustor includes: a first rotation member and a first guide member. A first hole is provided on the first side surface, so that a first external jig adjusts the first rotation member to rotate through the end of the first rotation member close to the first side surface and exposed from the first hole. A second hole is provided on the assembly surface, and the first guide member is configured to move along the second hole to adjust a protruding amount of the first guide member on the assembly surface.
