Abstract: A method for manufacturing a patterned layer on a substrate with a print head unit includes mounting a print head unit to an ink-jet device, the print head unit including at least two side print heads and one central print head, the print heads each comprising a nozzle line, rotationally moving at least one of the side print heads relative to the central pint head to achieve parallelism, rotating the print head unit around a rotating axis perpendicular to the substrate, linearly moving the side print heads along the respective nozzle line thereof to correspond to pitches of the nozzles and that of the cells on the substrate, depositing ink into the cells on the substrate, and solidifying the ink so as to form a patterned layer on the substrate.

Abstract: A print head unit (10) for manufacturing a patterned layer on a substrate is provided. The print head unit includes a first print head (12a), a second print head (12b), a third print head (12c), and a print head frame (11). The print head unit further includes parallelism adjusting means and position adjusting means. The parallelism adjusting means configured for rotationally moving at least one of the first print head and the third print head relative to the second print head so as to adjust parallelism between the first nozzle line, the second nozzle line, and the third nozzle line. The position adjusting means is configured for linearly moving at least one of the first print head and the third print head in the nozzle line direction.
