Touch display device includes a first touch electrode, a second touch electrode, and a first touch signal line. First touch electrode is located in a first area of touch display device and is configured to receive a first control signal to generate a first touch signal. Second touch electrode is located in a second area of touch display device and is configured to receive a second control signal to generate a second touch signal. First area is adjacent to second area without overlapping. First touch signal line is coupled to first touch electrode and second touch electrode. First touch signal line is configured to transmit first touch signal of first area at a first stage. First touch signal line is configured to transmit a common electrode signal at a second stage. First touch signal line is configured to transmit second touch signal of second area at a third stage.

Touch display device and driving method with line for transmitting touch signal and common electrode signal at different stages

A pixel structure includes a first, second and third electrode layers and a switch element. The second electrode layer is disposed above the first electrode layer and includes a first and second main body portions and a first and second branch portions. The first main body portion and the first branch portion extend in a first direction. The first branch portion protrudes from the first to second main body portion. The second branch portion protrudes from the second to first main body portion. The third electrode layer is disposed above the second electrode layer and includes a third and fourth main body portion and a third branch portion. The third and fourth main body portions extend in the first direction. The third branch portion connects the third to fourth main body portion. The switch element is electrically connected to the first or third electrode layer.
