Tiled Display Pixel Arrangement Asymmetry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In tiled display devices, the rotation of display panels to connect them can lead to unnatural pixel arrangements at boundaries, causing visual recognition of these boundaries by users, and existing methods require multiple types of display panels, increasing manufacturing costs.
Innovation Solution
A tiled display structure using four identical display panels with a conductive film layer and outer periphery power supply wires, where the panels are arranged in a lattice pattern with symmetrical sub-pixels and pad areas, allowing rotation without changing pixel arrangements and reducing peripheral area width to minimize visual unnaturalness and manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If display panels are rotated to connect them in a tiled structure, then the panels can be arranged in a lattice pattern, but the pixel arrangement becomes unnatural at boundaries causing visual recognition of boundaries
Solution Approach 1:
The pad area is positioned asymmetrically within the display panel structure, specifically located only in the fourth direction rather than symmetrically in all directions. This asymmetric design allows the panel to be rotated by 180 degrees and connected to adjacent panels while maintaining consistent pixel arrangements at boundaries, eliminating the visual recognition of boundaries between panels.
2Stability of the object's composition
If multiple types of display panels are used to maintain consistent pixel arrangements, then visual unnaturalness is reduced, but manufacturing costs increase
Solution Approach 1:
A single type of display panel is designed with multi-functional capability to serve all positions in the tiled structure. The panel includes a pad area positioned in the fourth direction that can connect to adjacent panels in any orientation, allowing one panel design to replace what would traditionally require multiple specialized panel types. This universal design maintains consistent pixel arrangements while significantly reducing manufacturing costs by using identical panels throughout.
3Adaptability or versatility
If pad areas are positioned on all sides of display panels, then connection flexibility is improved, but the peripheral area width increases causing visual unnaturalness
Solution Approach 1:
The pad area is strategically positioned only in the fourth direction of the display panel rather than uniformly on all sides. This localized placement optimizes the connection functionality for tiled arrangements while minimizing the peripheral area width that would otherwise be required. The asymmetric localization of the pad area reduces the visible peripheral regions at panel boundaries, thereby reducing visual unnaturalness while maintaining sufficient connection flexibility.

AI summary
A display device includes a tiled display structure including a first display panel, a second display panel adjacent to a first side of the first display panel, a third display panel adjacent to a second side of the first display panel, and a fourth display panel adjacent to a first side of the third display panel and a first side of the second display panel. Each of the first to fourth display panels includes a display area and a pad area, and each of the first to fourth display panels includes a plurality of pixels in the display area. Each of the pixels includes at least two sub-pixels. When viewed in a plan view of the tiled display structure, the at least two sub-pixels included in each of the pixels are repeatedly arranged in a row direction and a column direction on a plane of the tiled display structure.
