The touch control signal circuit and the display electrodes are connected with multi-position analog switch set. The analog switch makes the display electrodes either connect to display drive circuit to transmit display drive signal or connect to the touch control signal circuit to directly measure and transmit the touch control signal. The display driving and the touch control measuring time division multiplex the display screen electrodes. The display screen electrodes can not only be used to display driving but also be used to touch control measuring.
