    Abstract: An LED print drive method is applied to an LED array. The LED array includes a plurality of LED partitions, each LED partition includes one or more LED lights, and the plurality of LED partitions are distributed in a staggered manner based on a specified sequence. A print control unit generates a plurality of groups of data signals, and a drive control unit receives the plurality of groups of data signals from the print control unit. The drive control unit converts the plurality of groups of data signals into a plurality of groups of LED drive signals, and the drive control unit drives, in a time-sharing manner with the plurality of groups of LED drive signals, a corresponding LED partition to emit light. Light-emitting time of each LED partition corresponds to distribution of each LED partition.

    Abstract: A drive control method and a related device for a display panel that has different display areas are provided. Time-divided drive control is performed on pixel scan circuits corresponding to the different display areas, so that in a scenario in which some display areas do not need to display an image, a pixel scan circuit may be left idle for some time, to reduce power consumption required by the pixel scan circuits for scanning pixels in this time period. In addition, in the embodiments of this application, time-divided drive control is further performed on touch scan circuits and fingerprint scan circuits corresponding to the different display areas, independent power supplying is further used for pixels in the different display areas, and some functions of a display driver are enabled in a time-divided manner.
