Abstract
A projected capacitive touch device, a projected capacitive touch panel and touch control methods thereof are disclosed. The touching control method includes mixing a detecting signal and a feedback driving signal to generate a sending signal; transmitting the sending signal to at least one touch sensing unit of the projected capacitive touch panel, wherein an electrical field is generated on the touch sensing unit according to the feedback driving signal so that a feedback tactile sense according to the electrical field can be obtained by a user while touching the touch sensing unit.
