Abstract

A matrix-addressed tile comprises a tile substrate having a two-dimensional array of pixels arranged in rows and columns defining a contiguous pixel area that includes all of the pixels. A one-dimensional array of column-data lines electrically connected to columns of pixels and a one-dimensional array of row-select lines connected to rows of pixels are disposed on the tile substrate at least partially in the pixel area. At least one column-data line contact pad electrically connected to each of the column-data lines and at least one row-select contact pad electrically connected to each of the row-select lines are disposed at least partially within the pixel area and between at least two pixels. A matrix-addressed tiled system includes two or more matrix-addressed tiles electrically connected through the column-data line contact pads and row-select line contact pads.
