Abstract: Disclosed are a display apparatus, a drive chip, and an electronic device. When determining that a disconnected signal line exists, a drive chip sends a control signal to a signal line repair module, so that a shift output end of a first shift unit corresponding to the disconnected signal line outputs an enable signal, so as to control a corresponding connection switch in a connection switch group to be turned on, to enable the disconnected signal line to be electrically connected to a repair line. The display apparatus may repair a disconnected signal line without being returned to a factory and a manual operation.

Abstract: Embodiments of this application provide a frame rate switching method and a related apparatus, and relate to the field of terminal technologies. In a frame rate switching process, a plurality of transition frame rates can be set. A difference value between any two adjacent transition frame rates of the plurality of transition frame rates is less than a preset value, to enable switching of a screen refresh rate of a display screen to be smoother without spanning too much; and in a switching process, a drawing frequency on an application processor AP side of a terminal device is kept synchronously changing with a TE signal obtained from an IC by the AP side, to avoid frame loss during switching.

Abstract: Disclosed are a display apparatus, a drive chip, and an electronic device. When determining that a disconnected signal line (DL) exists, a drive chip sends a control signal to a signal line repair module, so that shift output ends (OUT) of a plurality of shift units sequentially output enable signals, and the shift unit corresponding to a connection switch electrically connected to the disconnected signal line (DL) continuously outputs enable signals, so that the connection switch electrically connected to the disconnected signal line (DL) is continuously turned on. The display apparatus may repair a disconnected signal line without being returned to a factory and a manual operation.
