Claim 10:
11. The touch display device according to claim 8, wherein the operation of inputting the first scanning signal to each of the first touch electrodes at a same time, and receiving the first sensing signal of each of the second touch electrodes to determine the suspected column according to the first sensing signal comprises:
inputting continuous K first scanning signals to each of the first touch electrodes at a same time, and receiving K first sensing signals of each of the second touch electrodes;
converting the K first sensing signals to K first capacitance data;
for each of the second touch electrodes, if it is detected that at least S first capacitance data in the K first capacitance data are greater than or equal to a first set threshold, determining the position of the second touch electrode to be the suspected column;
wherein, K is greater than or equal to S, and S is a positive integer greater than 1.
