Abstract (en)
[origin: EP0971336A2] A writing head (100) capable of rapidly and efficiently generating high field gradients while remaining amenable to low-voltage control utilises a piezoelectric (110) or Rosen transformer. A one- or two- dimensional array of such writing heads may be used to address a substrate (127) bearing an arrangement of electrically responsive, nonemissive display elements (125), applying an image pattern thereto. Similarly, the array of writing heads can be used to remove an image, returning the substrate (127) to its original unimaged state. <IMAGE>
