Claim Text:
1. A digital radiographic area detector comprising: an imaging array comprising a plurality of pixels, each pixel comprising at least one electrically chargeable photosensor and at least one thin-film transistor; a bias control circuit to provide a bias voltage to the photosensors for at least a portion of the imaging array; row address circuits to provide row addresses for the Portion of the imaging array; signal sensing circuits to provide signal sensing for the portion of the imaging array; and photosensor power control circuitry to maintain a first voltage across photosensors in the portion of the imaging array during readout of signals sensed from the portion of the imaging array, wherein the photosensor power control circuits comprise a first row address timing sequence for the row address circuits that is different from a second row address timing sequence used in the readout of signals from the portion of the imaging array.
