ABSTRACT:
A microfluidic printing apparatus responsive to an image file for printing a plurality of pixels on a display includes a plurality of ink delivery chambers; at least one ink channel for delivering ink to each ink delivery chamber; and an ink flow regulation controller (i.e., a piezo electric microvalve) for regulating the ink flow to the ink delivery chamber in response to the code values of the image file.
