The present invention provides inkjet print nozzle calibration systems and methods for calibrating an inkjet print nozzle. The systems may include an inkjet print nozzle adapted to dispense ink onto a substrate in response to a firing pulse voltage, a light source adapted to illuminate the dispensed ink, an imaging system adapted to measure a transmittance of light through the dispensed ink, and a controller adapted to controllably adjust the inkjet print nozzle based on the measured light transmittance. The methods may include dispensing ink onto a surface with an inkjet print nozzle set at a firing pulse voltage, measuring a light transmittance characteristic of the dispensed ink, determining a volume of ink dispensed based on the transmittance characteristic, and adjusting a fire pulse voltage of the inkjet print nozzle based on a difference between the determined volume of ink dispensed and an expected volume level of ink dispensed.

The invention provides methods, systems, and drivers for controlling an inkjet printing system and manufacturing display objects. The system may include a print controller including one or more drivers, at least one print head coupled to the drivers, a stage controller coupled to the print controller, one or more motors coupled to the stage controller, encoders coupled to the motors and the stage controller, and a host coupled to the stage controller and the print controller. The host is adapted to transfer pattern parameter data to the print controller, and the print controller is adapted to use the pattern parameter data to trigger the at least one print head to deposit ink into pixel wells on a substrate as the substrate is moved in a print direction by the at least one motor under the direction of the stage controller in response to a command from the host.

In a first aspect, an apparatus is provided for reducing an ink conglomerate during flat panel display manufacturing. The apparatus includes (1) an inkjet head adapted to dispense ink onto a substrate during inkjet printing; (2) an ink reservoir adapted to store ink for inkjet printing and supply the ink to the inkjet head; and (3) a conglomerate-reducing device adapted to break apart conglomerates in the ink before the ink reaches the inkjet head. Numerous other aspects are provided.

The invention provides methods, systems, and drivers for controlling an inkjet printing system. The driver may include logic including a processor, memory coupled to the logic, and a fire pulse generator circuit coupled to the logic. The fire pulse generator may include a connector to facilitate coupling the driver to a print head. The fire pulse generator circuit may also include a fixed current source circuit adapted to generate a fire pulse with a constant slew rate that facilitates easy adjustment of ink drop size. The logic is adapted to receive an image and to convert the image to an image data file. The image data file is adapted to be used by the driver to trigger the print head to deposit ink into pixel wells on a substrate as the substrate is moved in a print direction. Numerous other aspects are disclosed.
