Abstract
A touch display panel and a touch display device are provided. The touch electrode rows of the display panel include first touch electrode rows and second touch electrode rows. A number of touch signal lines connected to each touch electrode of the first touch electrode rows is greater than a number of touch signal lines connected to each touch electrode of the second touch electrode rows. The first touch electrode rows include an A-th touch electrode row; and the second touch electrode rows includes a B-th touch electrode row and a C-th touch electrode row adjacent to the B-th touch electrode row. An area of a touch electrode in the B-th touch electrode row is smaller than an area of a touch electrode in the A-th touch electrode row, and smaller than an area of a touch electrode in the C-th touch electrode row.
