Patent ID: 11100846

Abstract:
The present application discloses display-driving circuit for multiple rows of pixels in a column of a display panel. The display-driving circuit includes a compensation sub-circuit comprising a driving transistor, a data-input transistor, a drive-control transistor, a reset transistor, and a capacitor. The compensation sub-circuit is configured to compensate a drift of a threshold voltage of the driving transistor to drive light emission of multiple light-emitting diodes associated with respective multiple rows of pixels in the column. The display-driving circuit further includes multiple first emission-control transistors coupled in parallel between a high-voltage supply and a source electrode of the driving transistor and multiple second emission-control transistors respectively coupled between a drain electrode of the driving transistor and respective anodes of the multiple light-emitting diodes, and respectively turned on in different ones of multiple portions of one cycle time for displaying one frame of image.
