ABSTRACT:
An active matrix OED array includes an array area defined on a semiconductor substrate defining rows and columns of pixels and driver areas spaced from the array area with driver circuits including row drivers coupled to row buses and column drivers coupled to column buses formed in the driver areas. An active control circuit and an OED are formed in each pixel of the array area and coupled to a row and a column bus adjacent each pixel. A second substrate is formed of light transmissive material and includes externally accessible electrical connectors coupled to the driver circuits. The semiconductor substrate includes a first bump pad encircling the array area and the second substrate includes a mating second bump pad with the first and second bump pads engaged to seal the array area.
