Abstract
A touch display unit, a touch display panel and a method for driving the same are disclosed. The touch display unit includes: a first electrode and a second electrode; a touch electrode, which is disposed in a same layer as one of the first electrode and the second electrode and insulated from each other; and a signal line, which is configured to transmit a signal to the touch electrode. In the above touch display unit, a touch signal can be transmitted to the touch electrode through a dedicated signal line, therefore, the synchronous transmission of the display signal and the touch signal is realized.
