Abstract
A pixel includes a light emitting element and a driving element connected to the light emitting element. After an initial voltage is applied to one end of a current path of the driving element via the signal line, the pixel driving device acquires the threshold voltage of the driving element based on a voltage value at a terminal of the signal line when the initial voltage is cut off and the relaxation time is elapsed. The voltage-current characteristics of the driving element is acquired based on the voltage value at the terminal of the signal line when the current flows into the current path of the driving element via the signal line. The current gain value of the driving element is acquired based on the threshold voltage of the driving element. The image data is corrected based on the acquired threshold voltage.
