Abstract
A backplane operative to drive an array of emissive elements forming a part of a display or display like manufacturing device is disclosed. Each emissive element is mounted to a common pad supplied with current from a plurality of pixel drive elements, wherein each pixel drive element is controlled by a resident memory cell. The plurality of pixel drive elements is organized into a block similar to other blocks of pixel drive elements across the array. The common pad may be driven by a larger or lesser number of pixel drive elements than are present in a single block of pixel drive elements. If not needed, specific pixel drive elements present in a single block may be disabled through a mask change.
