Tiled Display Pad Structure for Seamless Groove-Protrusion Joining
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Tiled displays with multiple connected devices often exhibit visible seams due to non-display areas or bezels between adjacent units, disrupting viewer immersion in large-screen applications.
Innovation Solution
The solution involves connecting first display devices with grooves to second display devices featuring protrusions, where the protrusions are inserted into the grooves to form a seamless interface, utilizing anisotropic conductive films for electrical connection and employing materials like ITO, IZO, or metal layers for effective bonding.

If multiple display devices are connected to form a tiled display, then the screen size is increased, but visible seams appear between adjacent display devices
Solution Approach 1:
The non-display area (bezel) is extracted or removed from the interface between adjacent display devices. By eliminating the traditional bezel structure and replacing it with a groove-protrusion connection mechanism, the boundary between display areas becomes invisible, resolving the seam visibility issue while maintaining the large screen area achieved through tiling.
Solution Approach 2:
The protrusion of one display device is inserted into the groove of the adjacent display device, creating a nested structural relationship. This nesting allows the display areas to be positioned so closely that the boundaries become imperceptible, while the grooves and protrusions provide the necessary mechanical connection and alignment.
2Shape
If display devices are connected with grooves and protrusions, then visible seams are eliminated, but manufacturing complexity increases
Solution Approach 1:
The connection interface is segmented into two complementary parts: grooves on one display device and protrusions on the adjacent device. This segmentation allows each component to be manufactured independently with standard processes, then assembled together to achieve the seamless appearance. The segmentation simplifies the manufacturing of individual units while enabling the complex overall structure.
Solution Approach 2:
The groove-protrusion structure acts as an intermediary mechanism that bridges two display devices. Rather than requiring complex direct integration of display areas, this intermediary connection structure provides mechanical support, alignment, and electrical connectivity while maintaining the visual seamless appearance from the front.

AI summary
A tiled display includes a first display device comprising a first display area and a first pad area having grooves, and a second display device comprising a second display area and a second pad area overlapping the second display area, the second pad area having protrusions, wherein the protrusions are inserted into the grooves to connect the first pad area with the second pad area.
