Electronic display comprising an adjustable color filter

Abstract

A color display and an electronic apparatus including the color display are described herein. The color display includes a first substrate having an illuminating area, a color filter unit, a plurality of power sources and a colored fluid. The color filter unit has a first and second electrode on the illuminating area, wherein the first electrode includes a plurality of patterned electrodes. Each of the patterned electrodes of the first electrode is connected to one of the power sources, whereby different voltages are applied on the patterned electrodes. The colored fluid disposed between the first and second electrodes and partially covering the surface of the illuminating area, wherein a covered area of the illuminating area by the colored fluid is controlled by the voltage applied on the first and second electrodes

What is claimed is: 
     
         1 . A display, comprising:
 a first substrate having an illuminating area;   a color filter unit having a first and second electrode on the illuminating area, wherein the first electrode comprises a plurality of patterned electrodes;   a plurality of power sources, wherein each of the patterned electrodes of the first electrode is connected to one of the power sources, whereby different voltages are applied on the patterned electrodes; and   a colored fluid disposed between the first and second electrodes and partially covering the surface of the illuminating area, wherein a covered area of the illuminating area by the colored fluid is controlled by the voltage applied on the first and second electrodes.   
     
     
         2 . The display as claimed in  claim 1 , further comprising a black matrix disposed on the first substrate. 
     
     
         3 . The display as claimed in  claim 2 , wherein the black matrix partially covers the illuminating area which is covered by the colored fluid. 
     
     
         4 . The display as claimed in  claim 1 , further comprising a control unit disposed between the first and second electrodes for controlling at least a level of the colored fluid. 
     
     
         5 . The display as claimed in  claim 1 , further comprising a third electrode, wherein the second electrode is disposed between the first and third electrodes. 
     
     
         6 . The display as claimed in  claim 1 , wherein the colored fluid is oil or is oil-based. 
     
     
         7 . The display as claimed in  claim 1 , further comprising a power supply electrically connected with the second electrode for supplying control voltage to the second electrode.
