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: 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.
