Patent ID: 8451301

Claim:
A color display device, comprising: a plurality of pixel display elements, each of which includes a plurality of sub-pixel display elements, each of said sub-pixel display elements including first and second supports, first and second electrodes attached to inner faces of said first and second supports, respectively, a solution disposed between said first and second electrodes, and particles dispersed in said solution, said first support, said first electrode and said solution being light-transmissive, said particles of said sub-pixel display elements of a same one of said pixel display elements being electrically polarizable under a predetermined driving frequency; and a driving circuit coupled electrically to said sub-pixel display elements for supplying a voltage signal to each of said sub-pixel display elements, the voltage signals supplied to said sub-pixel display elements having the same predetermined driving frequency; wherein said first supports, said second supports, said solutions, and said particles of each of said pixel display elements are provided with respective color properties such that each of said sub-pixel display elements is able to display a first color when in a first display state, in which said particles are non-polarized and are randomly dispersed in said solution, and a second color when in a second state, in which said sub-pixel display element is supplied with the voltage signal having the predetermined driving frequency by said driving circuit to polarize said particles so as to result in formation of strings of said particles in said solution; said sub-pixel display elements of a same one of said pixel display elements displaying different colors when in one of the first and second display states.
