Claim 0:
1. A pixel circuit comprising:
a light emitting element;
a driving transistor configured to generate a driving current;
a write transistor including a control electrode configured to receive a write gate signal, a first electrode connected to a data line and configured to receive a data voltage, and a second electrode connected to a first electrode of a storage capacitor;
a first compensation transistor including a control electrode configured to receive a compensation gate signal, a first electrode connected to a control electrode of the driving transistor, and a second electrode connected to a first electrode of the driving transistor;
the storage capacitor including the first electrode connected to the second electrode of the write transistor, and a second electrode connected to the control electrode of the driving transistor; and
a test transistor including a control electrode, a first electrode configured to receive the data voltage, and a second electrode connected to a second electrode of the driving transistor,
wherein, in at least an array test period, the test transistor is configured to be turned on concurrently with the write transistor to apply the data voltage to the second electrode of the driving transistor while the write transistor is turned on to connect the first electrode of the storage capacitor to the data line.
