Abstract:
1. A display device comprised of a composite of the following layers: (i) a grounded transparent substrate film used to protect the thixotropic layer located directly underneath and used to provide a voltage potential across the thixotropic layer and the base of the micro-magnet X-Y array element under each pixel; (ii) a thixotropic gel layer composed of white or other colored colloid particles which exhibit covalent bond shearing upon the presence of a DC current and exhibiting the property of such bonds being re-established upon removal of the shearing current; (iii) an X-Y array of color capsule pixels organized in a dot-matrix arrangement, aligned in rows and column matrices and glued to a very flexible substrate film; (iv) an X-Y array of micro-magnet pairs each connected to a grid of very-thin electrical connectors and located directly underneath each one of the micro-capsule pixels in order to raise them by magnetic repulsion and to liquefy the gel surface directly above them by thixotropic bond shearing cause by the current.
