Droplet Discharging Apparatus Drive Waveform Segmentation

The drive waveform is segmented into multiple independent pulse signals. Instead of using a single long waveform for fine-driving, the invention divides the fine-driving waveform into multiple shorter pulses that can be distributed across different drive cycles. This segmentation allows the system to achieve fine-driving precision while maintaining shorter individual waveform lengths, thereby enabling higher driving frequencies.

The invention applies periodic action by repeating the segmented pulse signals across multiple drive cycles. The fine-driving effect is accumulated through periodic application of these short pulses, achieving the desired precision without requiring a single long waveform. This periodic repetition enables the system to maintain high driving frequency while still achieving fine-driving precision.

The long fine-driving waveform is segmented into multiple short pulse signals. Each pulse individually contributes to meniscus vibration control, and their cumulative effect achieves the desired stability. This segmentation allows the system to maintain proper meniscus control while using shorter waveforms that enable faster operation speeds.

The invention maintains continuous useful action by distributing the fine-driving pulses across multiple consecutive drive cycles. Instead of using one long waveform, the system continuously applies short pulses that collectively achieve the same meniscus vibration control effect, thereby maintaining operational stability while increasing speed.
