ABSTRACT:
A white or colored thixotropic gel is used in conjunction with an electro-mechanical addressable X-Y pixel array composed of micro-magnet pairs in order to produce a re-writable display surface for forming images. Images are formed on the surface of this display by changing the state of transparency of the gel surface, from semi-solid to semi-liquid as a result of thixotropic bond shearing. In addition, pixels are capsules filled with any given color. Furthermore, each active color capsule is forced upwards by magnetic repulsion between the twin-micro-magnet elements to help form images and break the surface tension of the gel and press against the front layer film and forming a visible pixel or; downwards to help erase the image by means of magnetic attraction between the two micro-magnets located directly underneath each pixel. In an embodiment of this invention, four or more layers of materials are bonded together in a flexible construct in order to provide to users a low-cost electronic paper-like display.
