Pixel driving circuit, pixel driving method and display device

A pixel driving circuit, applied to drive a light-emitting element, wherein the pixel driving circuit comprises a driving circuit and a light-emitting duration control circuit,

• a first end of the driving circuit is connected to a first voltage end, a second end of the driving circuit is connected to the light-emitting element via the light-emitting duration control circuit, and the driving circuit is configured to, under a control of a voltage of a control end of the driving circuit, control the first end and the second end to connect to each other;
• the light-emitting duration control circuit is configured to, in response to a first reset signal input by a first reset end and a control scanning signal input by a control scanning line, switch on or switch off a connection between the second end of the driving circuit and the light-emitting element, according to a control data voltage input by a control data line and a control initial voltage input by a control initial voltage end, to control a light-emitting period of the light-emitting element.
