Abstract
The present disclosure discloses a self-capacitive touch display panel and a display device, comprising: a substrate, and a plurality of top-emitting type organic electroluminescent structures disposed on the substrate and sharing one cathode. The self-capacitive touch display panel further comprises: a plurality of self-capacitive touch electrodes disposed at the same layer, positioned above the cathode and insulated with the cathode; a plurality of touch leads electrically connected with the plurality of self-capacitive touch electrodes; and a touch detection circuit, configured to determine a touch position by detecting the change of the capacitance values of the self-capacitive touch electrodes during a touch phase. The self-capacitive touch electrodes are connected with the touch detection circuit by way of the respective touch leads. The touch display panel reduces its thickness, guarantees a whole layer cathode structure of the organic electroluminescent structures and effectively guarantees the display quality.
