Abstract

A tiled display having pixels arranged in rows and columns, and including first and second tiles. The tiles comprise a substrate carrying a matrix of pixels arranged at a pixel pitch. The substrates comprise an edge extending between opposing faces in a depth direction. The substrate edges have a complementary shape, and face one another to establish a seam. The pixel pitch is maintained across the seam. Pixels of the second tile are not interposed between pixels of the first tile. The complementary shape includes a segment of the seam being oblique to the pixel rows, or the substrate edge of the first tile profiled in the depth direction whereby at least a section of the edge is non-perpendicular to the faces. The tiled display can maintain the pixel pitch at the seams at high resolutions (e.g., pixel pitch less than 0.5 mm).
