ABSTRACT:
A microfluidic display apparatus responsive to an image file for displaying a plurality of colored pixel, having at least one color for each pixel includes at least one fluid display chamber for displaying a color; a microchannel connected to the display chamber and including a first colored fluid which, when such fluid is moved to the display chamber, displays the first color as a pixel and a second colored fluid which, when moved to the display chamber, displays the second color as a pixel; and microfluidic pumps for each microchannel. A computer controls the microfluidic pumps in response to a particular pixel of the image file for selectively controlling the flow of fluid to the chamber for selectively displaying either the first or second colors or a fraction of each color thereof.
