Inkjet recording head substrate and drive control method, inkjet recording head, inkjet recording head cartridge and inkjet recording apparatus
摘要:
An inkjet recording head substrate having an electrothermal transducer for generating thermal energy used to discharge ink and a drive element for driving the electrothermal transducer mounted thereon includes a first circuit portion for outputting selection signals for selecting the electrothermal transducer to be driven at a amplitude level of a second voltage higher than a first voltage based on an input signal of the amplitude level of the first voltage, a second circuit portion for inputting the selection signals from the first circuit portion and controlling the drive element corresponding to the electrothermal transducer to be driven based on the selection signals subject to the second voltage, and a plurality of signal lines for transmitting the selection signals between the first and second circuit portions.
