1. An operation method of a timing controller, comprising:
receiving an instruction signal via a general purpose input/output pin of a touch driver;
starting a detection period according to a first edge switched from a first voltage level to a second voltage level of the instruction signal;
detecting a number of pulse signals of the instruction signal; and
determines a current operating status of the touch driver according to the number of pulse signals of the instruction signal during the detection period,
wherein the timing controller determines that the current operating status of the touch driver is one of touch operation type statuses according to the number of pulse signals of the instruction signal during the detection period being a default number.
