Tiled Display Device Alignment and Coupling Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large-sized display devices experience increased defective rates and reduced productivity due to the number of pixels, leading to a disconnection feeling when multiple display devices are connected, which affects image immersion.
Innovation Solution
A tiled display device design that includes a plurality of display devices with a support plate, alignment holes, and coupling members to align and fix the devices, minimizing the non-display area between them, and using a lower cover with protrusions to surround the devices and prevent visual recognition of boundaries.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple display devices are connected to form a large-sized display, then the screen size is increased, but the boundary portions between devices create a disconnection feeling that reduces image immersion
Solution Approach 1:
The invention extracts and removes the problematic boundary portions (bezel areas) between adjacent display devices through precise positioning using alignment holes. By taking out the visible seam elements and replacing them with a unified support plate structure, the disconnection feeling is eliminated while maintaining the multi-device configuration for large screen area.
Solution Approach 2:
The invention merges multiple display devices into a unified visual structure by using a common support plate that integrates the boundary portions of adjacent devices. The alignment holes and positioning structures combine the separate devices into a cohesive assembly where individual boundaries are no longer visually distinct, creating a seamless large-sized display.
2Area of stationary object
If the number of pixels in a display device is increased to achieve larger size, then the display area is expanded, but the defective rate increases and productivity deteriorates
Solution Approach 1:
The invention segments a large-sized display into multiple smaller display devices that are connected together. Instead of manufacturing one large display panel with numerous pixels (which increases defect rates), the system divides the total display area into separate modules, each with fewer pixels and lower defect rates, while maintaining overall productivity through parallel manufacturing of smaller units.
3Ease of operation
If alignment holes are designed with larger diameter to facilitate assembly, then ease of assembly is improved, but the non-display area increases which affects image immersion
Solution Approach 1:
The invention applies local quality by designing alignment holes with optimized dimensions that provide sufficient clearance for assembly operations only at the specific locations where holes are needed. The majority of the boundary area between devices is minimized and integrated into the support plate structure, ensuring that the non-display area is localized to the essential alignment features rather than extending across the entire boundary.

AI summary
Provided is a tiled display device including a plurality of display devices each having a display panel including a plurality of pixels and a support plate disposed under the display panel, a lower cover including an alignment hole and coupled to a lower portion of the support plate of each of the plurality of display devices, and a first coupling member including a base portion fixed to the support plate and a first coupling portion protruding from the base portion and passing through the alignment hole. A diameter of the first coupling portion is smaller than a diameter of the alignment hole.
