Claim 5:
6. The display driver according to claim 1, wherein the switching circuit includes:
a first switch configured to switch to output the source signal as the output signal according to a first switching signal included in the control signal; and
a second switch configured to switch to output the dummy source signal as the output signal according to a second switching signal included in the control signal, and
wherein the detection circuit provides the first switching signal for turning on the first switch and the second switching signal for turning off the second switch when the source signal has a level transition corresponding to the input signal during a preset test frame period, and provides the first switching signal for turning off the first switch and the second switching signal for turning on the second switch when the level transition is not in the source signal during the preset test frame period.
