Abstract
A transparent image producing display or receiver which uses a suspension fluid for producing pixels of an image includes at least one image-forming layer having a structure which defines a plurality of pixels, with the structure receiving a suspension fluid having field-driven particles, which move in response to an externally applied field, where, in a first condition, the field-driven particles produce a first level of transmitted incident light and, in an second condition, produce a second level of transmitted incident light.
Claims2
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.

An image-forming receiver 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;
- and
- 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 an electric field, forming a second image, so that the first image is viewed through the second image.
