Magnetic display system

A magnetic display system, comprising:

• a display comprising a non-magnetic substrate forming a front side, a back side and a microcapsule coating layer on said substrate, said microcapsule coating layer including a plurality of microcapsules, and said microcapsules containing a plurality of magnetic particles having a light absorbing characteristic and a plurality of non-magnetic particles having a light reflecting characteristic, both said magnetic and said non-magnetic particles being disposed in an oily liquid in said microcapsules;
• a first magnetic means for causing migration of said light absorbing magnetic particles in said microcapsules toward said back side of said display and migration of said light reflecting non-magnetic particles in said microcapsules toward said front side of said display in an area of said microcapsule coating layer to make said area light reflective from said front side of said display, said first magnetic means comprising a permanent magnet;
• and
• a second magnetic means for causing migration of said light absorbing magnetic particles in said microcapsules toward said front side of said display and migration of said light reflecting non-magnetic particles in said microcapsules toward said back side of said display at localized positions in said area of said microcapsule coating layer to make said localized positions light absorbing from said front side of said display for contrast with the light reflective remainder of said area, said second magnetic means comprising a permanent magnet.
