  • Patent number: 6177947
    Abstract: Apparatus for forming an image, comprising a storage for storing a digitized image and a receiver. The receiver includes a matrix, a thermomeltable material disposed in the matrix having a transition temperature range which is above room temperature wherein the viscosity of the thermomeltable material decreases substantially from below to above the transition temperature range, and field-driven particles immersed in the thermomeltable material, so that the particles change optical densities in response to an applied electric field when the thermomeltable material is above the transition temperature range and is stable at temperatures below the transition temperature range. An array of electrodes selectively applies electric fields at an image forming position on the receiver. The apparatus heats the receiver to control the temperature of the receiver to control the response of the field-driven particles in the receiver.

  • Patent number: 6128028
    Abstract: A electronic printing apparatus includes memory for storing a digitized image. A receiver is transported to an image forming position, the receiver including field-driven particles in a matrix that can change reflective density in response to an applied electric field. The apparatus further includes an array of electrodes for selectively applying electric fields at the image forming position across the receiver; a heater for heating the receiver to increase the temperature of the matrix so as to increase the mobility of the field-driven particles in the matrix; and electronic control circuitry coupled to the array for selectively applying voltages to the array so that fields are applied at the image forming position to the heated field-driven particles at particular locations on the receiver corresponding to pixels in response to the stored image whereby the electrode produces an image in the receiver corresponding to the stored image in the receiver.

  • Patent number: 5553951
    Abstract: An interactive dye thermal transfer printing apparatus and process uses a dye donor layer and a dye receiver layer, passing the dye donor layer and the opposed receiver layer between a thermal print head and a platen heated to raise the temperature of the dye receiver layer to its glass transition temperature. The thermal print head is image-wise energized to diffuse dye from the dye donor layer to the dye receiver layer.
