Active matrix organic light emitting diode pixel unit circuit and display panel
Abstract:
The present invention provides an active matrix organic light emitting diode, AMOLED pixel unit circuit and a display panel for integrating a touch screen circuit into the AMOLED pixel unit circuit, and manufacturing an AMOLED display panel having the functionality of a touch screen. The AMOLED pixel unit circuit comprises a driving module, configured to amplify a induction signal generated by a touch sensing module, output the induction signal through a induction signal output module, and drive a light emitting module; the light emitting control module, configured to control the light emitting module to emit light; a threshold compensation module, configured to compensate a threshold voltage of the driving module; a charging module, configured to charge the threshold compensation module; the touch sensing module, configured to generate the induction signal and output the induction signal to the driving module; and the induction signal output module, configured to output the induction signal amplified by the driving module.
