Abstract
A touch display panel and a display device utilize one thin film transistor is configured for one touch wiring. The thin film transistor is turned on during the lighting test and a corresponding electrical signal is input, which can change the floating state of the touch wiring. The coupling effect between the touch wiring and a data line can be reduced or eliminated, which reduces interference with a data signal, so that bright-line phenomenon caused by the floating touch wiring interfering with the data line during the lighting test can be improved or eliminated.
