Abstract:
A display comprising:a) a first image-forming layer including electric field-driven particles so that the electric field-driven particles move within the image-forming layer, in response to a selectively applied electric field, forming a first image; b) at least a second image-forming layer, deposed over the first image-forming layer, including electric field-driven particles so that the electric field-driven particles move within the image-forming layer, in response to a selectively applied electric field, forming a second image, so that the first image is viewed through the second image; c) at least one electric field forming means for selectively applying electric fields to the image-forming layer; and d) electronic control means coupled to the electric field forming means so that electric fields are selectively applied at locations on the image-forming layer corresponding to pixels in response to a stored image whereby the electrodes produces the image in the image-forming layer corresponding to the stored image.
