Abstract:
1. A patterning apparatus, comprising: a nozzle ejection device to eject a function liquid onto a substrate fed as a continuing flexible sheet in a shape of a belt through the apparatus in a conveying direction; an image detection device upstream in the conveyance direction of the nozzle ejection device to detect an alignment mark formed on the substrate in advance of ejecting the function liquid through the nozzle ejection device onto the substrate; a speed detection device upstream in the conveyance direction of the nozzle ejection device to detect a conveyance speed of the substrate to be conveyed; and an ejection control device to combine feedback data from the image detection device and the speed detection device so as to create an ejection command signal; wherein the function liquid is ejected through the nozzle ejection device onto the substrate being conveyed in accordance with the ejection command signal of the ejection control device.
