摘要： A data acquisition circuit sets one of the potential value at one end of a signal line and the value of a current flown thereto when one end of a current path of a drive device is connected to a light emitting device with the other end thereof set to a potential value where no current flows to the light emitting device. Then the circuit causes current to flow via the current path and the signal line and acquires one of the value of the current flown to the signal line and the potential value at the one end of the signal line according to the set value. A correction operation circuit acquires a threshold voltage and a current amplification factor of the drive device based on one of the current and potential values thus acquired as well as on one of the potential and current values thus set.
