Abstract
The present invention provides an organic light emitting diode pixel circuit, a driving method thereof and a display panel. The OLED pixel circuit comprises a light emitting module comprising an organic light emitting diode for emitting light; a light emitting control module for controlling the light emitting module to emit light; a driving module, so as to control the light emitting module to emit light; a threshold compensation module, and a data signal input module configured for inputting a data signal; the OLED pixel circuit further comprises: a touch sensing module configured for generating a touch sensing signal; and a touch detection module configured for detecting the touch sensing signal, and providing an initial voltage for the threshold compensation module, wherein the driving module amplifies the touch sensing signal generated by the touch sensing module and then outputs it to the touch detection module.
