Title: DISPLAY PANEL, PIXEL DRIVING CIRCUIT AND DRIVING METHOD THEREFOR
Abstract:
A pixel driving circuit, a pixel driving method and a display panel, the pixel driving circuit comprising a driving transistor (T0), a first switch (T1), a second switch (T2), a third switch (T3), a fourth switch (T4), a first capacitor (C1), a second capacitor (C2), an initial voltage signal terminal (VINI), a data voltage signal terminal (VDATA), a reset voltage signal terminal (VREF) and a driving voltage signal terminal (OVDD). The driving transistor is provided with a gate terminal (g), a source terminal (s) and a drain terminal (d). The first capacitor (C1) is connected between the source terminal (s) and the gate terminal (g), and the second capacitor (C2) is connected to the source terminal (s) and a charging voltage terminal (n) which is connected to the reset voltage signal terminal (VREF) and the data voltage signal terminal (VDATA) respectively by means of the first switch (T1) and the second switch (T2). The drain terminal (d) is connected to the driving voltage signal terminal (OVDD) by means of the third switch (T3), and the gate terminal (g) is connected to the initial voltage signal terminal (VINI) by means of the fourth switch (T4). Also provided are a pixel driving method and a display panel.
