Electro-optical display

Abstract

A display system encompasses electrodes that induce a convective flow of a carrier fluid that transports a colorant species that is suspended in the carrier fluid. At least one of the convection flow, speed, and direction of the colorant species is controlled by operation of the electrodes.

1 . A display system comprising:
 means for inducing a convective flow of a carrier fluid that is configured to transport a colorant species, suspended in the carrier fluid, between different parts of the system; and   means for controlling at least one of the convection flow, speed, and direction of the colorant species.   
     
     
         2 . The display system of  claim 1  wherein the carrier fluid is comprised of one of polar properties, non-polar properties, or liquid crystal properties. 
     
     
         3 . The display system of  claim 1  wherein the means for inducing the convective flow is comprised of at least one of: electrokinetic elements, electrophoretic elements, charge injection elements, heating elements, microfluidic elements, micro-electromechanical elements, chemical reaction regions, or a combination of these elements. 
     
     
         4 . The display system of  claim 1  wherein the means for inducing the convective flow comprises a plurality of electrodes having at least one electrical potential across them. 
     
     
         5 . The display system of  claim 4  wherein the plurality of electrodes are coupled to the carrier fluid.
