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.

Abstract: In a camera tracking method and apparatus, and a device, a director device determines speech information of speaker in a preset time period. The director device determines a current speaker based on second video information collected by the first camera at a current moment and second audio information collected by the plurality of MICs at the current moment. The director device controls a director status of at least one director camera based on the speech information of speaker, the current speaker, and a speaker shot by the at least one director camera at the current moment. The director camera is configured to send a director video stream to another conference site. This avoids frequent and unnecessary switching of the director camera.

Abstract: A display panel (11) with a low signal transmission power and large cabling space, and a semiconductor display apparatus including the display panel (11) are provided. The display panel (11) includes pixel areas (DB) that are of N rows and M columns and that are connected in a matrix, each pixel area (DB) includes pixel drive modules that are of Q rows and P columns and that are connected in a matrix, each pixel drive circuit (PD) is connected to at least one pixel unit (P), and the pixel drive circuit (PD) drives, based on to-be-displayed image data, the pixel unit (P) to emit light to display an image. All pixel areas (DB) in any column of the pixel areas (DB) are connected to data interfaces (DI) in a same group, and pixel areas (DB) in different columns are connected to data interfaces (DI) in different groups.
