Liquid Discharge Apparatus Drive Waveform Timing Optimization

The invention divides the drive waveform into multiple segments with different timing characteristics. By segmenting the drive signal and applying different timing adjustments to different nozzle groups, the system compensates for potential variations caused by common grounding without requiring separate ground connections for each nozzle, thus resolving the contradiction between circuit simplicity and landing accuracy.

The invention changes the timing parameter of the drive waveform dynamically. By adjusting the timing of discharge pulses based on the nozzle's position and potential variation characteristics, the system compensates for the effects of resistance components in the common ground path, maintaining droplet landing accuracy while preserving the simplified common grounding configuration.

The invention makes a single amplifier circuit universal by enabling it to generate multiple types of drive waveforms through timing adjustment. The same amplifier circuit can produce drive signals for droplets of different sizes by modifying the timing parameters, eliminating the need for multiple dedicated amplifier circuits while maintaining short waveform lengths for high productivity.

The invention introduces dynamic timing adjustment capability to the amplifier circuit. The circuit can dynamically change the timing characteristics of the drive waveform based on the required droplet size, allowing one circuit to perform multiple functions that would otherwise require several static circuits, thus improving productivity without proportionally increasing device complexity.
