Title:
PIXEL CIRCUIT, DISPLAY PANEL, DISPLAY DEVICE, AND DRIVING METHOD
Document Type and Number:
WIPO Patent Application WO/2020/238490
Kind Code:
A1
Abstract:
Provided are a pixel circuit, a display substrate, a display apparatus and a driving method. The pixel circuit comprises a data writing sub-circuit and a driving sub-circuit, wherein the data writing sub-circuit is connected to a scanning signal end, a control signal end, a data signal end and the driving sub-circuit. The data writing sub-circuit needs to respond to a scanning signal provided by the scanning signal end and a control signal provided by the control signal end to output a data signal to the driving sub-circuit, and therefore, the potential of the control signal provided by the control signal end can be controlled, the pixel circuit only located in an area of an image to be refreshed drives a light-emitting element connected to the pixel circuit to emit light, and thus realizing image refreshing of a localized area.
