Sub-Panel Edge Pixel Layout for Seamless Tiled Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tiled display products suffer from discrepancies in pixel pitch at seams, leading to pixel dislocation or excessive pitch, which negatively impacts the display effect and uniformity.
Innovation Solution
A display panel design featuring sub-panels tiled in sequence, where the effective display bodies in the first and second pixels closest to the edges and the third pixels between them are strategically positioned to minimize the spacing difference at seams, ensuring uniform pixel pitch across the panel.

Engineering Contradiction Analysis
1Ease of manufacture
If sub-panels are tiled in sequence with uniform pixel pitch, then manufacturing is simplified, but pixel dislocation occurs at seams affecting display quality
Solution Approach 1:
The patent applies local quality by making the pixel pitch non-uniform only at specific locations (seam areas) while maintaining uniform pitch in other regions. The first and second pixels adjacent to seams have different pitch distances from their respective edges, creating a local adjustment zone that compensates for seam displacement without affecting the overall uniformity of the display panel.
Solution Approach 2:
The patent employs asymmetry by setting the pixel pitch distances asymmetrically at the seam boundaries. Specifically, the distance from the first pixel to the first edge (p8) and from the second pixel to the second edge (p9) are designed to be non-uniform, creating an asymmetric pixel arrangement that compensates for the seam width and eliminates the black strip effect.
2Manufacturing precision
If pixel pitch is adjusted to eliminate black strip effect, then display quality improves, but manufacturing complexity increases
Solution Approach 1:
The patent segments the pixel columns into distinct groups: first pixels adjacent to the first edge, second pixels adjacent to the second edge, and third pixels in between. This segmentation allows for different pitch configurations in different segments, with the first and second pixels having adjusted pitch distances (p8 and p9) to compensate for seam effects, while the third pixels maintain standard uniform pitch.

AI summary
A display panel includes a plurality of sub-panels tiled in sequence along a first direction. The sub-panels have a first edge and a second edge in the first direction. The sub-panels include a column of first pixels closest to the first edge, a column of second pixels closest to the second edge, and a plurality of columns of third pixels between the column of first pixels and the column of second pixels. A sum of a distance between effective display bodies in the first pixels and the first edge and a distance between effective display bodies in the second pixels and the second edge is smaller than a spacing between effective display bodies in two adjacent columns of the third pixels.
