Abstract: A display panel includes pixels connected to first and second data lines and a readout line. The data driver supplies data signals to the first and second data lines and supplies an initialization voltage to the readout line. Each of the pixels includes at least one light emitting element and a driving transistor. The driving transistor controls an amount of current based on a difference between a corresponding data signal among the data signals and an initialization voltage. In a sensing mode, the data driver supplies a test voltage to the first data line and a first off voltage to the second data line in a first period and supplies a second off voltage to the second data line in a second period after the first period. The second off voltage is different from the test voltage and the first off voltage.
