Claim 12:
13. A sensing method of mobility of the pixel driving module of claim 4, comprising:
in a second reset phase, inputting a turn-on signal to the gate of the second transistor and the gate of the third transistor via the first gate line terminal and the second gate line terminal, respectively; controlling the second switch and the third switch to be turned on and the first switch, the fourth switch, the fifth switch and the sixth switch to be turned off; and inputting a second data signal to the first electrode of the second transistor via the data line terminal, such that a signal from the first signal terminal is written to the sensing line and the second data signal is written to the storage capacitor;
in a second charging phase, inputting a turn-on signal to the gate of the third transistor via the second gate line terminal; not inputting a turn-on signal to the gate of the second transistor via the first gate line terminal; and controlling the first switch, the second switch, the third switch, the fourth switch, the fifth switch and the sixth switch to be turned off, such that a signal from the first voltage terminal is written to the sensing line; and
in a second sensing phase, controlling the first switch, the third switch and the fourth switch to be turned on and the second switch, the fifth switch and the sixth switch to be turned off; not inputting a turn-on signal to the gate of the second transistor and the gate of the third transistor via the first gate line terminal and the second gate line terminal, respectively; and acquiring a voltage signal at the output terminal of the operation amplifier, so as to calculate the mobility of the first transistor according to the second data signal and the voltage signal at the output terminal of the operation amplifier.
