DISPLAY APPARATUS, DRIVING CHIP, AND ELECTRONIC DEVICE

Disclosed are a display apparatus, a drive chip (30), and an electronic device, so as to repair a disconnected signal line without being returned to a factory and a manual operation. In a signal line repair module (10) of the display apparatus, input ends of different connection switches (12) are electrically connected to signal lines, output ends thereof are electrically connected to a repair line (DUM), output ends of connection control units (14) are connected to control ends of connection switches (12), output ends of selector switches (13) are electrically connected to connection control ends of the connection control units (14), and shift output ends of first shift units (11) are electrically connected to input ends of the selector switches (13). When determining that a disconnected signal line exists, the drive chip (30) sends a control signal to the signal line repair module (10), so that when the shift output end of the first shift unit (11) corresponding to the disconnected signal line outputs an enable signal, the selector switch (13) corresponding to the shift output end is turned on, and then the connection control unit (14) keeps outputting a turn-on signal to the control end of the corresponding connection switch (12).
