Abstract
Display tiles comprising pixel elements on a first surface of a substrate connected by an electrode, a driver located opposite the first surface, and a connector wrapped around an edge surface of the substrate connecting the driver to the pixel elements. Displays comprised of display tiles and methods of manufacturing display tiles and displays are also disclosed.
Claims22
A display tile comprising:
- a first substrate comprising a first surface, a second surface opposite the first surface and an edge surface between the first surface and the second surface, the edge surface defining an outer perimeter;
- the first surface comprising an array of pixel elements arranged in a plurality of rows of pixel elements and a plurality of columns of pixel elements, each row of pixel elements connected by a row electrode and each column of pixel elements connected by a column electrode;
- a row driver that activates the rows of pixel elements and a column driver that activates the columns of pixel elements, the row and the column drivers located opposite the first surface;
- a plurality of row electrode connectors, each row electrode connector wrapped around the edge surface and electrically connecting a row electrode, a row of pixel elements and the row driver;
- and
- a plurality of column electrode connectors, each column electrode connector wrapped around the edge surface and electrically connecting a column electrode, a columns of pixel elements and the column driver,
- wherein when any edge surface of the display tile is placed in close proximity to an adjacent display tile of a tile display, a pixel pitch across a tile-to-tile seam of the tile display is approximately matched to that within the display tile.
