Abstract
The driving method includes: inputting a first scanning signal to each of the first touch electrodes at a same time, and receiving a first sensing signal of each of the second touch electrodes to determine a suspected column according to the first sensing signal; inputting a second scanning signal to each of the second touch electrodes at a same time, and receiving a second sensing signal of each of the first touch electrodes to determine a suspected row according to the second sensing signal; determining a suspected touch region according to the suspected column and the suspected row; and sequentially inputting a third scanning signal row by row to each of the first touch electrodes in the suspected touch region, and receiving a third sensing signal of each of the second touch electrodes in the suspected touch region to determine a touch position according to the third sensing signal.
