Patent ID: 8207954

Claim:
An imaging device having a hybrid drive, comprising: a) a single continuous substrate; b) a two-dimensional pixel array formed on the substrate, the pixels associated into a plurality of pixel groups, each pixel group including at least four pixels and including a separate set of group row electrodes and group column electrodes connected to and driving only the pixels in the corresponding pixel group, each of the group row electrodes connected to two or more pixels and each of the group column electrodes connected to two or more pixels, so that a single group row electrode together with a single group column electrode drives a single pixel; and c) two or more chiplets located over the substrate and within the pixel array, each chiplet associated with a pixel group and having connections to each of the associated group row electrodes and associated group column electrodes and having at least as many storage elements as are in either dimension of the pixel group, the storage element storing a value representing a desired luminance for a pixel and the chiplet using the value to control the desired luminance of each pixel in its associated pixel group.
