Active-matrix display and drive method thereof

An active-matrix display comprising:

• a data line;
• one or a plurality of select lines intersecting with the data line;
• a control unit that supplies a voltage signal and a current signal to the data line;
• and
• a pixel circuit that receives the voltage signal and the current signal from the data line to drive a light emitting element,
• wherein the pixel circuit includes:
• a transistor that controls a current to be supplied to the light emitting element;
• a voltage holding unit connected to a gate of the transistor;
• a first switch controlled by a signal supplied through the select lines to connect the gate of the transistor to the data line;
• and
• a second switch controlled by the signal supplied through the select lines to connect the drain of the transistor to the data line,
• wherein the control unit includes:
• a voltage or first current source that supplies a voltage or current pulse to the data line in order to make the voltage holding unit to hold the voltage signal for making the light emitting element emit a light having predetermined brightness in a first selection period in which the first switch is closed by the signal supplied through the select lines;
• a second current source that supplies the current signal for making the light emitting element emit the light having the predetermined brightness to the data line in order to make the voltage holding unit to hold the current signal in a second selection period in which the first switch and the second switch are closed by the signal supplied through the select lines;
• a detection circuit that detects potential held in the voltage holding unit in the second selection period;
• and
• a correction unit that corrects the voltage signal on the basis of a relationship between the current signal and the detected potential.
