Abstract
A method of fabricating an active matrix LED array includes forming layers of material on a substrate, which layers cooperate to emit light when activated. Row and column dividers are formed in the layers to divide the layers into an array of LEDs arranged in rows and columns. One FET is formed on the row dividers in association with each LED and a source of each FET is connected to an anode of the associated LED. Row and column buses are formed on the row and column dividers, respectively, and the drain of each FET is connected to an adjacent row bus with the gate of each FET being connected to an adjacent column bus. A cathode for each LED is connected as a common terminal for all of the LEDs in the array.
