Title:
PIXEL DRIVING CIRCUIT AND DRIVING METHOD THEREFOR, AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/083308
Kind Code:
A1
Abstract:
A pixel driving circuit and a driving method therefor, and a display device. The pixel driving circuit comprises: a current control sub-circuit (1), configured to output a driving current from an output terminal in response to a light-emitting control signal of a light-emitting control signal terminal (EM); a time control sub-circuit (2), configured to transmit a time modulation signal of a time modulation signal terminal (Data-T) to a third control terminal (N1) in response to a time control signal of a time control signal terminal (Gate-T), and control a time at which the driving current flows through a light-emitting element (D); and an initial time control sub-circuit (3), configured to transmit an initial control signal of an initial control signal terminal (Initial-T) to an output terminal of an initial time control sub-circuit (3) in response to an initial time control signal of an initial time control signal terminal (Reset-T). The time control sub-circuit (2) controls the time when the driving current flows through the light-emitting element (D) in response to the time modulation signal transmitted by the time control sub-circuit (2) to the third control terminal (N1) and the initial control signal transmitted by the initial time control sub-circuit (3) to the third control terminal (N1).
