Abstract
An electronic printing apparatus is disclosed for forming images on a receiver which stores a digital image. The apparatus uses a receiver that includes field-driven particles in a matrix that change optical density in response to an applied electric field, a substrate, and a conductive portion disposed between the matrix and the substrate. The apparatus further includes an array of electrodes cooperating with the conductive portion for selectively applying electric fields across the matrix at the image forming position so that the field-driven particles change optical density, and electronic control circuitry electrically coupled to the array and the conductive portion for selectively applying voltages to the array so that fields are applied at the image forming position to field-driven particles at particular locations on the receiver corresponding to pixels in the stored image whereby the electrodes produce an image in the receiver corresponding to the stored image.
