PIXEL DRIVING CIRCUIT AND METHOD FOR DRIVING SAME, AND DISPLAY PANEL

WIPO Patent Application WO/2021/135971

A1

Provided is a pixel driving circuit. The circuit comprises a driving control sub-circuit (10) and a time control sub-circuit (20), wherein the driving control sub-circuit (10) is at least connected to a first scanning signal end (G1), a first data signal end (D1), a first power source voltage signal end (S1), an enabling signal end (EM) and an element to be driven (L); the driving control sub-circuit (10) comprises a first driving sub-circuit (101); the first driving sub-circuit (101) outputs a driving signal to drive the operation of the element to be driven (L); the time control sub-circuit (20) is at least connected to a first voltage signal end (V1), a second voltage signal end (V2), a third voltage signal end (V3), a second scanning signal end (G2), a second data signal end (D2), the enabling signal end (EM) and the first driving sub-circuit (101); the time control sub-circuit (20) comprises a second driving sub-circuit (201); and the second driving sub-circuit (201) is configured to output a third voltage signal to the first driving sub-circuit (101), such that the first driving sub-circuit (101) stops outputting the driving signal, so as to control the operation duration of the element to be driven (L).
