Claim 16:
17. The display device of claim 16, wherein the test strobe signal includes a second positive test strobe signal generated by shifting the phase of the strobe signal by a second positive reference phase and a second negative test strobe signal generated by shifting the phase of the strobe signal by a second negative reference phase,
wherein the timing controller is configured to decrease the power voltage by a first falling value when the error bit occurs in the test write operation and the test read operation performed based on the first positive test strobe signal or the first negative test strobe signal and the error bit does not occur in the test write operation and the test read operation performed based on the second positive test strobe signal and the second negative test strobe signal, and
wherein the timing controller is configured to decrease the power voltage by a second falling value greater than the first falling value when the error bit occurs in the test write operation and the test read operation performed based on the first positive test strobe signal or the first negative test strobe signal and the error bit occurs in the test write operation and the test read operation performed based on the second positive test strobe signal or the second negative test strobe signal.
