Patent ID: 7918702

Claim:
A method for manufacturing a large area LED array, comprising: providing a stack of row electrodes, each row electrode arranged in a meander pattern on a substrate, at least two U-turns on one side of the meander each being connected to a LED mounting surface to form a row of mounting surfaces, providing a stack of column electrodes, each column electrode arranged in a meander pattern on a substrate, at least two U-turns on one side of the meander each being connected to a LED mounting surface to form a column of mounting surfaces, arranging said stacks of row and column electrodes so that rows and columns of mounting surfaces intersect each other at a plurality of intersection points, mounting LEDs at said intersection points, so that a first terminal of each LED is connected to a mounting surface of a row electrode, while a second terminal of each LED is connected to a mounting surface of a column electrode, removing substrate material surrounding each electrode, stretching said stack of row electrodes in a direction parallel to the rows of mounting surfaces, stretching said stack of column electrodes in a direction parallel to the columns of mounting surfaces, thereby separating said intersection points from each other.
