摘要：A print head has driver circuitry that dynamically drives a row of drivenelements, such as light-emitting elements, by driving different combinations of first andsecond terminals. The print head includes memory circuits storing compensation data for
the driven elements, and multiplexing circuits that select the compensation dataaccording to the combination of terminals being driven, thereby enabling the
compensation data to be stored in the print head despite the use of dynamic driving. Thecompensation data are used in adjusting the amount of energy supplied to the drivenelements. The amount of compensation data to be stored may be reduced by sharing theupper bits of the compensation data among a group of driven elements.
