Abstract:
A microfluidic display apparatus responsive to an image file for displaying a plurality of colored pixels by using different colored fluids, comprising:a) a plurality of stacked fluid display chambers which are stacked in groups of fluid display chambers, each such group of stacked fluid display chambers being arrayed to display the color in a pixel;b) a plurality of microchannels, with each microchannel being connected to a fluid display chamber in a stack of a group of fluid display chambers;c) microfluidic means for each microchannel in a stack, each microfluidic means being responsive to a pixel of the image file for selectively controlling the flow of a colored fluid to its display chamber in a group of stacked fluid display chambers so as to produce a desired color in its pixel when viewed by an observer.
