Abstract
A pixel driving circuit (31) includes: a driving sub-circuit (311), a first light-emission control sub-circuit (312), a second light-emission control sub-circuit (313), a data write sub-circuit (314), a compensation sub-circuit (315) and a first reset sub-circuit (316). The driving sub-circuit (311) includes a control terminal, a first terminal and a second terminal; and in an initialization phase (t1) in one display frame of the pixel driving circuit (31), a voltage difference between the control terminal of the driving sub-circuit (311) and the first terminal of the driving sub-circuit (311) is fixed. A pulse width of the signal of the first reset signal control terminal is adjustable.
