Abstract
An OLED touch display panel and a touch display device are disclosed. The OLED touch display panel includes a TFT back plate and a cathode layer disposed on the TFT back plate. The cathode layer includes a plurality of touch leads which are insulated from each other and a plurality of self-capacitance electrodes which are insulated from each other and arranged in a form of a matrix. The touch leads extend to a non-display region of the OLED touch display panel. Each one of the touch leads is connected with one of the self-capacitance electrodes, and resistance values of the touch leads connected with the self-capacitance electrodes of a same row are all consistent.
