Abstract
The present disclosure provides a pixel driving circuit and a display apparatus, and belongs to the field of display technology. The pixel driving circuit includes a gate driving sub-circuit configured to output a gate driving signal with an adjustable duty ratio; a first light-emitting control sub-circuit configured to control the first voltage control sub-circuit to output a first light-emitting voltage or control the second voltage control sub-circuit to output a second light-emitting voltage by a data voltage signal in response to a light-emitting control signal; a light-emitting time control sub-circuit configured to output the first light-emitting voltage or the second light-emitting voltage received by the light-emitting time control sub-circuit under the control of the gate driving signal; and a second light-emitting control sub-circuit configured to output the received first or second light-emitting voltage to a light-emitting device to be driven under the control of the light-emitting control signal.
