Abstract
An AMOLED pixel unit () and a driving method therefore, as well as an AMOLED display device including the AMOLED pixel unit (), are disclosed. The AMOLED pixel unit () includes a pixel circuit () and an organic light-emitting diode () connected to the pixel circuit (). The pixel circuit () includes a capacitor (Cs), an initialization unit connected to one terminal of the capacitor (Cs), a data writing unit and a light-emitting control unit. The other terminal of the capacitor (Cs) is connected to a first scan control line (Sn). The initialization unit is connected to a second scan control line (Sn). The data writing unit is connected to a third scan control line (Sn) and a data line (Dm). The light-emitting control unit is connected to a fourth scan control line (Sn). The AMOLED pixel unit () can effectively avoid an impact of leak currents or threshold voltage differences on the capacitors (Cs), allowing uniform light brightness of the AMOLED display device.
