Electrophoretic display

An electrophoretic display comprising a plurality of pixels and an electrophoretic fluid which comprises two types of charged particles that exhibit no or minimum bistability, which are dispersed in a colored solvent, wherein

• a) the two types of charged particles are of the same color, but carry opposite charge polarities, such that application of driving voltage of either polarity across the electrophoretic fluid, will cause the pixel to have the color of the charged particles, which is an “on” state of the pixel;
• b) the colored solvent has a color which is visually distinguishable from the color of the charged particles, such that turning off the driving voltage from the “on” state, will cause the color of the pixel to be the color of the colored solvent;
• and
• c) the color difference of a pixel between the “on” state and the state established after turning off the driving voltage from the “on” state, expressed in ΔE, is at least 5;
• wherein ΔE=√{square root over ((L*2−L*1)2+(a*2−a*1)2+(b*2−b*1)2)}, L*1, a*1, b*1 and L*2, a*2, b*2 are color coordinates for the colors of the “on” state of the pixel and state of the pixel established after turning off the driving voltage from the “on” state as defined by the CIE XYZ color space.
