Abstract
The present disclosure provides an AMOLED pixel driving circuit, method and a display device. The AMOLED pixel driving circuit is for driving an organic light-emitting diode (OLED) and includes: a charge storage unit configured to be charged in a data writing stage and be discharged in a pixel lighting stage to light up the OLED; a data writing unit configured to write a data current in the data writing stage; a light-emitting control unit configured to control to enable a connection between the charge storage unit and the OLED in the pixel lighting stage. The AMOLED pixel driving circuit further includes a current amplification unit configured to, in the data writing stage, amplify the data current and charge the charge storage unit with the amplified data current.
