Patent ID: 8217891

Claim:
A display comprising: a first substrate comprising a first base and a first electrode layer, the first electrode layer being disposed on the first base and having at least one first electrode; a partition element disposed on the first substrate; a second substrate disposed on the partition element, the second substrate comprising a second base and a second electrode layer, the second electrode layer being disposed on the second base and the second electrode layer being a planar electrode, an area of the first electrode on the first base being smaller than an area of the second electrode on the second base, wherein the partition element forms at least one accommodating room between the first substrate and the second substrate, and the first electrode layer or the second electrode layer is adapted to forming a non-uniform electric field in the accommodating room; a dielectric liquid disposed in the accommodating room and having a first dielectric constant; a plurality of dielectrophoretic particles dispersed in the dielectric liquid, wherein each of the dielectrophoretic particles has a first color and a second dielectric constant different from the first dielectric constant; and a plurality of electrophoretic particles dispersed in the dielectric liquid, wherein each of the electrophoretic particles has a second color different from the first color; wherein there are one electrode layer formed on the first substrate and one electrode layer formed on the second substrate, when the display is in a first operating state, the dielectrophoretic particles move towards the second electrode layer, and the electrophoretic particles move towards the first electrode layer, when the display is in a second operation state, the dielectrophoretic particles and the electrophoretic particles move towards the second electrode layer.
