Abstract

The color display of the present invention involves a two particle system and is capable of displaying multiple colors with high quality black and white states. The color states are suitable for highlighting function. The color display does not require alignment between the electrodes and the display cells in which a display fluid is filled, which significantly reduces the complexity of the design and also lowers the manufacturing costs.
