Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in manufacturing tiling displays is the precise alignment and assembly of large and heavy display panels, which is difficult due to their size and weight, leading to potential gaps and increased manufacturing time and cost.
Innovation Solution
A display panel alignment device with a frame and panel movement controllers that allow for precise movement and rotation of display panels in multiple directions, using a rotator, x-axis mover, and y-axis mover to minimize gaps and facilitate accurate positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple display panels are assembled to manufacture larger displays, then the display size and manufacturing cost efficiency are improved, but the alignment precision deteriorates due to the large size and heavy weight of the panels
Solution Approach 1:
The invention divides the alignment task into multiple independent alignment devices, each responsible for a specific display panel. Each alignment device includes a movement controller that independently controls the position of its associated panel, enabling precise alignment of each segment (panel) while maintaining the overall large display structure.
Solution Approach 2:
The invention introduces alignment devices as intermediary components between the display panels and the assembly system. These alignment devices include movement controllers that act as mediators to precisely position and align the heavy display panels, solving the control difficulty caused by panel weight and size.
2Manufacturing precision
If display panels are precisely aligned to eliminate gaps, then the visual quality is improved, but the manufacturing time and operational complexity increase due to the difficulty of controlling heavy panels
Solution Approach 1:
The alignment devices include movement controllers that enable self-alignment of display panels. The controllers automatically adjust panel positions to achieve precise alignment and eliminate gaps, reducing the need for manual intervention and lengthy adjustment processes, thereby decreasing manufacturing time while maintaining high precision.
3Device complexity
If manual alignment methods are used for heavy display panels, then the device complexity is reduced, but the alignment precision and control accuracy deteriorate
Solution Approach 1:
The invention replaces manual mechanical alignment methods with automated movement controllers that use motorized mechanisms (such as screw mechanisms or linear actuators) to precisely control panel positions. This substitution of mechanical control systems enables accurate positioning of heavy panels without requiring complex manual operation procedures.

AI summary
A display panel alignment device of a tiling display includes a frame including panel seating portions and a gap around the panel seating portions, and a panel movement controller disposed in each of the panel seating portions. A display panel is disposed in each of the panel seating portions. The panel movement controller controls a movement of the display panel in a front direction, a rear direction, a left direction, and a right direction, and controls rotation of the display panel.
