Tiled Display Chassis Assembly for Low-Seam Large Screens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Tiled display devices with large screen sizes face increased defect rates and reduced productivity due to the number of pixels, leading to visibility issues and immersion problems caused by seams between connected display devices.
Innovation Solution
The design incorporates a first and second display device with corresponding chassis, where the end portions of the chassis are directly connected, and the display devices come into direct contact, with specific connection portions and overlapping areas to minimize seam visibility and enhance stability against external impacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a large screen size is manufactured using a single display device, then the screen area increases, but the defect rate increases and productivity deteriorates
Solution Approach 1:
The large display device is divided into multiple small display devices (first display device, second display device, third display device, fourth display device) that are connected together to form a tiled display structure. This segmentation allows each individual display device to be manufactured with fewer pixels and lower defect rates, while the overall screen area is maintained through the combination of multiple units.
2Area of stationary object
If multiple display devices are connected to form a large screen, then the screen area increases, but seam visibility increases and immersion deteriorates
Solution Approach 1:
A sealing member is introduced as an intermediary component between adjacent display devices to fill gaps and cover seams. The sealing member extends from the first chassis to the second chassis, creating a visual barrier that hides the boundary portions between display devices, thereby reducing seam visibility and improving overall appearance without affecting the large screen area.
3Area of stationary object
If multiple display devices are connected to form a large screen, then the screen area increases, but stability against external impact deteriorates
Solution Approach 1:
Multiple chassis (first chassis, second chassis, third chassis, fourth chassis) are directly connected to each other to form an integrated support structure. This merging of chassis provides enhanced structural stability and strength against external impacts, as the combined chassis structure distributes and resists external forces more effectively than individual chassis would alone.
4Ease of manufacture
If tolerance in cutting and attachment is not controlled, then manufacturing ease increases, but seam visibility increases
Solution Approach 1:
The sealing member acts as a mediator that compensates for manufacturing tolerances in cutting and attachment. By filling the gaps created by tolerance variations, the sealing member ensures that seams remain hidden even when cutting and attachment tolerances are not tightly controlled, thus maintaining low seam visibility while preserving ease of manufacture.

AI summary
A tiled display device including a first display device; a second display device located at one side of the first display device in a first direction; a first chassis disposed under the first display device to support the first display device; and a second chassis disposed under the second display device to support the second display device. An end portion of the first chassis and an end portion of the second chassis are directly connected to each other, and an end portion of the first display device and an end portion of the second display device come into direct contact with each other.
