Abstract
A display apparatus responsive to an image file for displaying a plurality of pixels including a plurality of ink display chambers; ink channels for delivering melted inks to each ink display chamber; and first heater elements for melting solid ink which is to be delivered through the ink channels to the display chambers. The apparatus further includes second heater elements for melting solid ink in the display channels after an image has been displayed; and a computer for controlling the first heater elements for causing solid ink melted by the first heater elements to be delivered to the display chambers where it solidifies to form a display of an image and for controlling the second heater elements for melting solid ink in the chambers to discard ink in the display chambers whereby the display apparatus is conditioned to form a new display image.
