Abstract

The invention discloses a driving circuit of an AMOLED display panel, which comprises a first thin film transistor, a second thin film transistor, a third thin film transistor, a storage capacitor, a fourth thin film transistor, a fifth thin film transistor and an organic light emitting diode. The invention also provides an AMOLED display panel. The driving circuit of the AMOLED display panel and the AMOLED display panel of the present invention avoid the influence of the threshold voltage of the thin film transistor on the light-emitting brightness of the organic light-emitting diode through the setting of five thin film transistors and a storage capacitor, thereby improving the display of the AMOLED display panel. Brightness uniformity.

Description
