Title:
DISPLAY PANEL AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/174404
Kind Code:
A1
Abstract:
A display panel (10) and a display device (40). The display panel (10) comprises a base substrate (101) and sub-pixels (100) on the base substrate (101). Each sub-pixel (100) comprises a light emitting element (120) and a pixel circuit for driving the light emitting element. The pixel circuit comprises a data write sub-circuit (111), a storage sub-circuit (113), a driving sub-circuit (112), and a shunt noise reduction sub-circuit (114). The data write sub-circuit (111) is configured to transmit a data signal (Vd) to a first end of the storage sub-circuit (113) in response to a control signal. The driving sub-circuit (112) comprises a control electrode (150), a first electrode (151), and a second electrode (152). The control electrode (150) of the driving sub-circuit (112) is coupled to the storage sub-circuit (113), the first electrode (151) of the driving sub-circuit (112) is configured to receive a first power voltage (VDD), and the second electrode (152) of the driving sub-circuit (112) is coupled to a first electrode (121) of the light emitting element (120). The driving sub-circuit (112) is configured to drive, in response to the voltage of the control electrode (150), the light emitting element (120) to emit light. The shunt noise reduction sub-circuit (114) comprises a noise reduction transistor (N4). The gate (N4G) and the first pole (N4D) of the noise reduction transistor (N4) are coupled to the same electrode of the driving sub-circuit (112).
