Document Type and Number:
WIPO Patent Application WO/2023/039893
Kind Code:
A1
Abstract:
A pixel circuit, a driving method and a display device. The pixel circuit comprises a light-emitting element (10), a driving circuit (11), a first light-emitting control circuit (12), a first control circuit (13), a first initialization circuit (14) and a second light-emitting control circuit (15). Under the control of a first scanning signal, the first control circuit (13) controls the communication between a first node (N1) and a control node (N0); under the control of a second light-emitting control signal, the first initialization circuit (14) controls the writing of a first initial voltage (Vi1) into the control node; and under the control of the second light-emitting control signal, the first light-emitting control circuit (12) controls the communication between a power supply voltage terminal (Vd) and a second node (N2).
