Abstract
A microfluidic printing apparatus responsive to an image file for printing a plurality of pixels on a display is disclosed. The apparatus includes a plurality of ink delivery chambers; ink channels for delivering ink to each ink delivery chamber; and heater elements associated with particular delivery chambers and effective for causing the transfer of heat to inks in such chambers for regulating ink flow from the ink delivery chambers to the display. The apparatus further includes a circuit for controlling the heater elements for regulating the ink flow in response to the code values of the image file.
