Abstract: Methods and systems are described herein for driving droplet ejection devices with multi-level waveforms. In one embodiment, a method for driving droplet ejection devices includes applying a multi-level waveform to the droplet ejection devices. The multi-level waveform includes a first section having at least one compensating edge and a second section having at least one drive pulse. The compensating edge has a compensating effect on systematic variation in droplet velocity or droplet mass across the droplet ejection devices. In another embodiment, the compensating edge has a compensating effect on cross-talk between the droplet ejection devices.

Abstract: There is provided a liquid discharge apparatus including: a liquid discharge head which includes a channel structure provided with a nozzle and a liquid channel, a driving element, and a driving unit; a light emitting part; a liquid receiving part receiving light passed through or reflected by the meniscus; and a controller. The controller controls the driving unit to apply at least one of several kinds of meniscus driving signals to the driving element in a state that the light emitting part emits the light to the nozzle, thereby vibrating the meniscus in the nozzle, and is configured to determine a recovery operation from among several kinds of recovery operations which have mutually different liquid discharge amounts to be discharged from the nozzle, on the basis of an amount of light which is received by the light receiving part in the case of vibrating the meniscus of the liquid.

Abstract: An ink printing process employs per-nozzle droplet volume measurement and processing software that plans droplet combinations to reach specific aggregate ink fills per target region, guaranteeing compliance with minimum and maximum ink fills set by specification. In various embodiments, different droplet combinations are produced through different print head/substrate scan offsets, offsets between print heads, the use of different nozzle drive waveforms, and/or other techniques. Optionally, patterns of fill variation can be introduced so as to mitigate observable line effects in a finished display device. The disclosed techniques have many other possible applications.

Abstract: A droplet measurement system (DMS) is used in concern with an industrial printer used to fabricate a thin film layer of a flat panel electronic device. A clear tape serves as a printing substrate to receive droplets from hundreds of nozzles simultaneously, while an optics system photographs the deposited droplets through the tape (i.e., through a side opposite the printhead). This permits immediate image analysis of deposited droplets, for parameters such as per-nozzle volume, landing position and other characteristics, without having to substantially reposition the DMS or printhead. The tape can then be advanced and used for a new measurement. By providing such a high degree of concurrency, the described system permits rapid measurement and update of droplet parameters for printers that use hundreds or thousands of nozzles, to provide a real-time understanding of per-nozzle expected droplet parameters, in a manner that can be factored into print planning.

Abstract: A method and system of facilitating development of fluids having a variety of elemental compositions are disclosed. A graphical user interface allows user interaction with a lab deposition system to control fluid drop ejection of fluids through multiple nozzles. Fluid drop ejection and drop formation can vary from fluid to fluid, and require adjustments to waveform parameters of a drive pulse applied to the multiple nozzles. The system implements a drop watcher camera system to capture real-time still and video images of fluid drops as they exit the multiple nozzles. The captured drop formation of the fluid drops are displayed to the user, and based on the images the waveform parameters are adjusted and customized specific for individual fluid. In addition to adjusting the drive pulse that effects fluid drop ejection, a tickle pulse can also be adjusted and customize to prevent clogging of the nozzles.

Abstract: In a liquid material discharge control method, timing signals generated periodically are used to control discharge timing for discharging a liquid material from a plurality of nozzles onto a workpiece during a scan in which the nozzles and the workpiece are moved relative to each other. The liquid material discharge control method includes calculating a first elapsed time in a relative movement between the nozzles and the workpiece by counting a first prescribed number of outputs of the timing signals that define the discharge timing, comparing the first elapsed time with a first predicted time at which the nozzles are predicted to reach intended discharge positions on the workpiece, and discharging the liquid material from the nozzles onto the workpiece upon the first predicted time having elapsed when the first elapsed time is at least shorter than the first predicted time.
