Pixel control structure, array, backplane, display, and method of manufacturing

摘要

Pixel control structure for use in a backplane for an electronic display, including a transistor (20) that has a gate, a source, a drain, and an organic semiconductor element. The pixel control structure is formed by a first patterned conductive layer portion (10), a second patterned conductive layer portion (12), a dielectric layer portion (14), and an organic patterned semiconductive layer portion (16). The dielectric layer portion comprises an overlap region defined by overlap of the second conductive layer portion over the first conductive layer portion. The overlap region defines an overlap boundary, defined by an edge portion of the first patterned conductive layer portion and an edge portion of the second patterned conductive layer portion. The patterned semiconductive layer portion extends over the overlap region and away from the overlap region so as to extend from both first and second edge portions.
